Ubuntu14.04源码编译安装php7.0和mysql5.6

Corwien
在阿里云Ubuntu14.04找不到php7版本的apt安装包,所以,只能利用源码来安装,中间遇到不少坑,在和mysql、Nginx配置时又出现了问题,所以,这里记录下来。

一、apt安装mysql

1、获取包

1、之前系统安装了mysql5.5版本,这里我们直接卸载,如果之前没安装过的可以跳过该步骤。

# 首先删除mysql:
sudo apt-get remove mysql-*
# 然后清理残留的数据
dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P

2、更新包:

apt update

3、查找可安装的mysql版本

apt-cache search mysql

打印:

...
mysql-server-5.6 - MySQL database server binaries and system database setup
mysql-server-core-5.6 - MySQL database server binaries
mysql-source-5.5 - MySQL source
mysql-source-5.6 - MySQL source
mysql-testsuite - MySQL testsuite
mysql-testsuite-5.5 - MySQL testsuite
mysql-testsuite-5.6 - MySQL 5.6 testsuite

可以看到我们的包资源有 mysql-server-5.6 版本。

4、安装

 apt-get install mysql-server-5.6

在安装的过程中会需要输入数据库密码,直接输入即可。

5、检查mysql是否运行
安装成功后,使用如下命令查看是否正常运行:

sudo service mysql status

可以看到mysql已经安装成功在运行了:

root@iZ:/tmp# sudo service mysql status
mysql start/running, process 848

2、修改配置

6、更改配置
先进入到mysql服务:

#用户名为root,密码假设是123456
mysql -uroot -p123456

更改root访问的IP权限,否则外网连接会被拒绝的。

> use mysql;
> update user set host='%' where user = 'root' and host = '::1'

7、修改MySQL监听IP

默认情况下MySQL监听的是127.0.0.1,也就是本机,所以只有本机能够连接上,因此需要将MySQL改成监听远程主机IP或者所有IP。

打开配置文件 /etc/mysql/my.cnf, 找到 bind-address,如果监听固定远程IP,则改成远程主机IP,若监听所有IP,则改成0.0.0.0或者注释bind-address,我们这里直接注释掉,修改完成后重启。

#bind-address = 127.0.0.1

重启mysql

service mysql restart

8、完整的 my.cnf 配置内容:
/etc/mysql/my.cnf

#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
# 
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...
# Remember to edit /etc/mysql/debian.cnf when changing the socket location.
[client]
port        = 3306
socket        = /var/run/mysqld/mysqld.sock

# Here is entries for some specific programs
# The following values assume you have at least 32M ram

# This was formally known as [safe_mysqld]. Both versions are currently parsed.
[mysqld_safe]
socket        = /var/run/mysqld/mysqld.sock
nice        = 0

[mysqld]
#

# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
#bind-address        = 127.0.0.1

#
key_buffer        = 16M
max_allowed_packet    = 16M
thread_stack        = 192K
thread_cache_size       = 8
# This replaces the startup script and checks MyISAM tables if needed
# the first time they are touched

# Be aware that this log type is a performance killer.
# As of 5.1 you can enable the log at runtime!

#general_log             = 1
#
# Error log - should be very few entries.
#
log_error = /var/log/mysql/error.log
#
# Here you can see queries with especially long duration
#log_slow_queries    = /var/log/mysql/mysql-slow.log
#long_query_time = 2

#
# The following can be used as easy to replay backup logs or for replication.
# note: if you are setting up a replication slave, see README.Debian about
#       other settings you may need to change.
#server-id        = 1
#log_bin            = /var/log/mysql/mysql-bin.log
expire_logs_days    = 10
max_binlog_size         = 100M
innodb_large_prefix = ON
innodb_file_format = BARRACUDA
max_connections = 10000
#binlog_do_db        = include_database_name
#binlog_ignore_db    = include_database_name
#
# * InnoDB
#
# InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/.
# Read the manual for more InnoDB related options. There are many!
#
# * Security Features
#
# Read the manual, too, if you want chroot!
# chroot = /var/lib/mysql/
#
# For generating SSL certificates I recommend the OpenSSL GUI "tinyca".
#
# ssl-ca=/etc/mysql/cacert.pem
# ssl-cert=/etc/mysql/server-cert.pem
# ssl-key=/etc/mysql/server-key.pem



[mysqldump]

max_allowed_packet    = 16M

[mysql]
#no-auto-rehash    # faster start of mysql but no tab completition

[isamchk]
key_buffer        = 16M

#
# * IMPORTANT: Additional settings that can override those from this file!
#   The files must end with '.cnf', otherwise they'll be ignored.
#
!includedir /etc/mysql/conf.d/

可以看到,我们新增了几个参数到该配置文件:

#5.6兼容5.7出现的mb4索引超过限制问题
innodb_large_prefix = ON
innodb_file_format = BARRACUDA
# 最大连接数10000,默认数很小
max_connections = 10000

好了到目前为止,我们已经使用apt成功安装了mysql5.6

二、源码编译安装php7.0

1、下载源码

源码包我们放在/var/software目录下:

root@i:/var/software# wget http://am1.php.net/distributions/php-7.0.0.tar.gz

2、解压安装

1、解压

cd /var/software
tar -zxvf php-7.0.0.tar.gz
cd php-7.0.0

2、编译

root@i:/var/software/php7.0# ./configure --prefix=/usr/local/php7.0 --with-config-file-path=/usr/local/php7.0 --enable-mbstring --enable-ftp --with-gd  --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-pear --enable-sockets --enable-zip --enable-fpm --enable-xml --enable-sockets --with-gd --with-zlib --with-iconv --enable-zip --enable-pcntl --enable-cli --with-openssl --with-curl 

--prefix表示php安装到哪个路径,如果不写系统会默认放到一个路径,我们也安装php必须用的扩展pdo_mysql,openssl,curl等等。

我们将 php7 安装到 /usr/local/php7.0 目录下。

3、编译安装:

make && make install

4、测试:
我们安装的目录在:/usr/local/php7.0,该目录下有这几个文件夹。

drwxr-xr-x 2 root root  4096 Nov 28 23:22 bin
drwxr-xr-x 3 root root  4096 Nov 29 09:40 etc
drwxr-xr-x 3 root root  4096 Nov 28 23:17 include
drwxr-xr-x 3 root root  4096 Nov 28 23:17 lib
drwxr-xr-x 4 root root  4096 Nov 28 23:17 php
drwxr-xr-x 2 root root  4096 Nov 28 23:22 sbin
drwxr-xr-x 4 root root  4096 Nov 28 23:17 var

进入到安装目录后,然后通过命令./bin/php -m查看扩展:

# cd /usr/local/php7.0
# ./bin/php -m
[PHP Modules]
Core
ctype
date
dom
fileinfo
filter
hash
iconv
json
libxml
pcre
PDO

3、简化PHP执行命令

我们可以看到,如果要执行php脚本,需要根据php完整路径来执行/usr/local/php7.0/bin/php -m,这样会很繁琐,非常麻烦,如果设置一个别名,后边直接跟一个脚本就非常简单,比如这样:php -m,是不是非常简洁?

修改执行命令需要将执行的命令添加到配置文件 /root/.bashrc中:

vim /root/.bashrc
# 新增php快捷命令
alias php=/usr/local/php7.0/bin/php

重新加载:

source /root/.bashrc

这样,我们就可以直接使用 php 来执行命令了,即查看php版本:

root@i:/usr/local/php7.0# php -v
PHP 7.0.0 (cli) (built: Nov 28 2019 23:16:55) ( NTS )
Copyright (c) 1997-2015 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2015 Zend Technologies

4、php-fpm配置

为php-fpm命令建立软链接,加入到环境变量中

ln -s /usr/local/php7.0/sbin/php-fpm /usr/local/sbin/php-fpm

复制php配置文件目录下的 php-fpm.conf.default,并重命名为 php-fpm.conf

cp /usr/local/php7.0/etc/php-fpm.conf.default  /usr/local/php7.0/etc/php-fpm.conf

编辑 php-fpm.d/www.conf,设置 php-fpm 模块使用 www-data 用户和 www-data 用户组的身份运行,监听者也是www-data

user=www-data
group = www-data

listen.owner = www-data
listen.group = www-data
listen.mode = 0660

listen=/usr/local/php7.0/var/run/php7.0-fpm.sock

这里有一个大坑,搞了好久好整明白,默认是监听 listen=127.0.0.1:9000,在Nginx fastcgi_pass 我们使用的是socket监听的,所以,这里需要改为socket监听模式:

listen=/usr/local/php7.0/var/run/php7.0-fpm.sock

这个路径 /usr/local/php7.0/ 是我们的php安装路径,如果使用其他路径,会找不到 php7.0-fpm.sock 文件的,所以,这里必须是你的PHP安装路径,另外,php7.0-fpm.sock 默认是不存在的,在运行时才会产生。

root@i:/usr/local/php7.0/var/run# ls -l
total 4
-rw-r--r-- 1 root     root     4 Nov 29 11:40 php-fpm.pid
srw-rw---- 1 www-data www-data 0 Nov 29 11:40 php7.0-fpm.sock

www.conf完整配置:
路径:/usr/local/php7.0/etc/php-fpm.d/www.conf

; Start a new pool named 'www'.
; the variable $pool can we used in any directive and will be replaced by the
; pool name ('www' here)
[www]

; Per pool prefix
; It only applies on the following directives:
; - 'access.log'
; - 'slowlog'
; - 'listen' (unixsocket)
; - 'chroot'
; - 'chdir'
; - 'php_values'
; - 'php_admin_values'
; When not set, the global prefix (or /usr/local/php7.0) applies instead.
; Note: This directive can also be relative to the global prefix.
; Default Value: none
;prefix = /path/to/pools/$pool

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
;       will be used.
user=www-data
group = www-data

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific IPv4 address on
;                            a specific port;
;   '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
;                            a specific port;
;   'port'                 - to listen on a TCP socket to all addresses
;                            (IPv6 and IPv4-mapped) on a specific port;
;   '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
;listen = 127.0.0.1:9000
listen=/usr/local/php7.0/var/run/php7.0-fpm.sock
; Set listen(2) backlog.
; Default Value: 511 (-1 on FreeBSD and OpenBSD)
;listen.backlog = 511

; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions.
; Default Values: user and group are set as the running user
;                 mode is set to 0660
listen.owner = www-data
listen.group = www-data
listen.mode = 0660
; When POSIX Access Control Lists are supported you can set them using
; these options, value is a comma separated list of user/group names.
; When set, listen.owner and listen.group are ignored
;listen.acl_users =
;listen.acl_groups =

; List of addresses (IPv4/IPv6) of FastCGI clients which are allowed to connect.
; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
; must be separated by a comma. If this value is left blank, connections will be
; accepted from any ip address.
; Default Value: any
;listen.allowed_clients = 127.0.0.1

; Specify the nice(2) priority to apply to the pool processes (only if set)
; The value can vary from -19 (highest priority) to 20 (lower priority)
; Note: - It will only work if the FPM master process is launched as root
;       - The pool processes will inherit the master process priority
;         unless it specified otherwise
; Default Value: no set
; process.priority = -19

; Choose how the process manager will control the number of child processes.
; Possible Values:
;   static  - a fixed number (pm.max_children) of child processes;
;   dynamic - the number of child processes are set dynamically based on the
;             following directives. With this process management, there will be
;             always at least 1 children.
;             pm.max_children      - the maximum number of children that can
;                                    be alive at the same time.
;             pm.start_servers     - the number of children created on startup.
;             pm.min_spare_servers - the minimum number of children in 'idle'
;                                    state (waiting to process). If the number
;                                    of 'idle' processes is less than this
;                                    number then some children will be created.
;             pm.max_spare_servers - the maximum number of children in 'idle'
;                                    state (waiting to process). If the number
;                                    of 'idle' processes is greater than this
;                                    number then some children will be killed.
;  ondemand - no children are created at startup. Children will be forked when
;             new requests will connect. The following parameter are used:
;             pm.max_children           - the maximum number of children that
;                                         can be alive at the same time.
;             pm.process_idle_timeout   - The number of seconds after which
;                                         an idle process will be killed.
; Note: This value is mandatory.
pm = dynamic

; The number of child processes to be created when pm is set to 'static' and the
; maximum number of child processes when pm is set to 'dynamic' or 'ondemand'.
; This value sets the limit on the number of simultaneous requests that will be
; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
; CGI. The below defaults are based on a server without much resources. Don't
; forget to tweak pm.* to fit your needs.
; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand'
; Note: This value is mandatory.
pm.max_children = 15

; The number of child processes created on startup.
; Note: Used only when pm is set to 'dynamic'
; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
pm.start_servers = 2

; The desired minimum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.min_spare_servers = 1

; The desired maximum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.max_spare_servers = 3

; The number of seconds after which an idle process will be killed.
; Note: Used only when pm is set to 'ondemand'
; Default Value: 10s
;pm.process_idle_timeout = 10s;

; The number of requests each child process should execute before respawning.
; This can be useful to work around memory leaks in 3rd party libraries. For
; endless request processing specify '0'. Equivalent to PHP_FCGI_MAX_REQUESTS.
; Default Value: 0
;pm.max_requests = 500

; The URI to view the FPM status page. If this value is not set, no URI will be
; recognized as a status page. It shows the following informations:
;   pool                 - the name of the pool;
;   process manager      - static, dynamic or ondemand;
;   start time           - the date and time FPM has started;
;   start since          - number of seconds since FPM has started;
;   accepted conn        - the number of request accepted by the pool;
;   listen queue         - the number of request in the queue of pending
;                          connections (see backlog in listen(2));
;   max listen queue     - the maximum number of requests in the queue
;                          of pending connections since FPM has started;
;   listen queue len     - the size of the socket queue of pending connections;
;   idle processes       - the number of idle processes;
;   active processes     - the number of active processes;
;   total processes      - the number of idle + active processes;
;   max active processes - the maximum number of active processes since FPM
;                          has started;
;   max children reached - number of times, the process limit has been reached,
;                          when pm tries to start more children (works only for
;                          pm 'dynamic' and 'ondemand');
; Value are updated in real time.
; Example output:
;   pool:                 www
;   process manager:      static
;   start time:           01/Jul/2011:17:53:49 +0200

;
; By default the status page output is formatted as text/plain. Passing either
; 'html', 'xml' or 'json' in the query string will return the corresponding
; output syntax. Example:
;   http://www.foo.bar/status
;   http://www.foo.bar/status?json
;   http://www.foo.bar/status?html
;   http://www.foo.bar/status?xml
;
; By default the status page only outputs short status. Passing 'full' in the
; query string will also return status for each pool process.
; Example:
;   http://www.foo.bar/status?full
;   http://www.foo.bar/status?json&full
;   http://www.foo.bar/status?html&full
;   http://www.foo.bar/status?xml&full
; The Full status returns for each process:
;   pid                  - the PID of the process;
;   state                - the state of the process (Idle, Running, ...);
;   start time           - the date and time the process has started;
;   start since          - the number of seconds since the process has started;
;   requests             - the number of requests the process has served;
;   request duration     - the duration in µs of the requests;
;   request method       - the request method (GET, POST, ...);
;   request URI          - the request URI with the query string;
;   content length       - the content length of the request (only with POST);
;   user                 - the user (PHP_AUTH_USER) (or '-' if not set);
;   script               - the main script called (or '-' if not set);
;   last request cpu     - the %cpu the last request consumed
;                          it's always 0 if the process is not in Idle state
;                          because CPU calculation is done when the request
;                          processing has terminated;
;   last request memory  - the max amount of memory the last request consumed
;                          it's always 0 if the process is not in Idle state
;                          because memory calculation is done when the request
;                          processing has terminated;
; If the process is in Idle state, then informations are related to the
; last request the process has served. Otherwise informations are related to
; the current request being served.
; Example output:

; - remove a server from a group if it is not responding (load balancing);
; - trigger alerts for the operating team (24/7).
; Note: The value must start with a leading slash (/). The value can be
;       anything, but it may not be a good idea to use the .php extension or it
;       may conflict with a real PHP file.

;      it can accept a strftime(3) format:
;      %d/%b/%Y:%H:%M:%S %z (default)
;      The strftime(3) format must be encapsuled in a %{<strftime_format>}t tag

;  %T: time the log has been written (the request has finished)
;      it can accept a strftime(3) format:

; Default Value: not set
; Note: slowlog is mandatory if request_slowlog_timeout is set
;slowlog = log/$pool.log.slow

; The timeout for serving a single request after which a PHP backtrace will be

; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
;request_slowlog_timeout = 0

; The timeout for serving a single request after which the worker process will
; be killed. This option should be used when the 'max_execution_time' ini option
; does not stop script execution for some reason. A value of '0' means 'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
;request_terminate_timeout = 0

; Set open file descriptor rlimit.
; Default Value: system defined value
;rlimit_files = 1024

; Set max core size rlimit.
; Possible Values: 'unlimited' or an integer greater or equal to 0
; Default Value: system defined value
;rlimit_core = 0

; Chroot to this directory at the start. This value must be defined as an
; absolute path. When this value is not set, chroot is not used.
; Note: you can prefix with '$prefix' to chroot to the pool prefix or one
; of its subdirectories. If the pool prefix is not set, the global prefix
; will be used instead.
; Note: chrooting is a great security feature and should be used whenever
;       possible. However, all PHP paths will be relative to the chroot
;       (error_log, sessions.save_path, ...).
; Default Value: not set
;chroot =

; Chdir to this directory at the start.
; Note: relative path can be used.
; Default Value: current directory or / when chroot
;chdir = /var/www

; Redirect worker stdout and stderr into main error log. If not set, stdout and
; stderr will be redirected to /dev/null according to FastCGI specs.
; Note: on highloaded environement, this can cause some delay in the page
; process time (several ms).
; Default Value: no
;catch_workers_output = yes

; Clear environment in FPM workers
; Prevents arbitrary environment variables from reaching FPM worker processes
; by clearing the environment in workers before env vars specified in this
; pool configuration are added.
; Setting to "no" will make all environment variables available to PHP code
; via getenv(), $_ENV and $_SERVER.
; Default Value: yes
;clear_env = no

; Limits the extensions of the main script FPM will allow to parse. This can
; prevent configuration mistakes on the web server side. You should only limit
; FPM to .php extensions to prevent malicious users to use other extensions to
; exectute php code.
; Note: set an empty value to allow all extensions.
; Default Value: .php
;security.limit_extensions = .php .php3 .php4 .php5 .php7

; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from
; the current environment.
; Default Value: clean env
;env[HOSTNAME] = $HOSTNAME
;env[PATH] = /usr/local/bin:/usr/bin:/bin
;env[TMP] = /tmp
;env[TMPDIR] = /tmp
;env[TEMP] = /tmp

; Additional php.ini defines, specific to this pool of workers. These settings
; overwrite the values previously defined in the php.ini. The directives are the
; same as the PHP SAPI:
;   php_value/php_flag             - you can set classic ini defines which can
;                                    be overwritten from PHP call 'ini_set'.
;   php_admin_value/php_admin_flag - these directives won't be overwritten by
;                                     PHP call 'ini_set'
; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.

; Defining 'extension' will load the corresponding shared extension from
; extension_dir. Defining 'disable_functions' or 'disable_classes' will not
; overwrite previously defined php.ini values, but will append the new value
; instead.

; Note: path INI options can be relative and will be expanded with the prefix
; (pool, global or /usr/local/php7.0)

; Default Value: nothing is defined by default except the values in php.ini and
;                specified at startup with the -d argument
;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f www@my.domain.com
;php_flag[display_errors] = off
;php_admin_value[error_log] = /var/log/fpm-php.www.log
;php_admin_flag[log_errors] = on
;php_admin_value[memory_limit] = 32M

5、php.ini文件

我们可以看到 /usr/local/php7.0 安装的目录里边没有 php.ini 配置文件,这就需要我们把源码包的 php.ini 拷贝到我们的安装目录。

拷贝:

# 进入源码包
cd /var/software/php7.0
cp php.ini-development /usr/local/php7.0/etc

修改文件名 php.ini-development 为 php.ini:

cd /usr/local/php7.0/etc
mv php.ini-development php.ini

这里还有一个坑,就是有时候我们改了php.ini文件后没有生效,这样的问题怎么排查呢?

可以用下边这个命令php -i | grep php.ini来看:

php -i | grep php.ini
Configuration File (php.ini) Path => /usr/local/php7.0

我们可以看到,最终的执行路径在 /usr/local/php7.0 下面,正常我们是放在 /usr/local/php7.0/etc 下边,编译之后会放在 /usr/local/php7.0 下,所以我们把etc下边的移到 php7.0安装目录下面即可:

root@i:/usr/local/php7.0# mv ./etc/php.ini ./

然后再查看:

root@i:/usr/local/php7.0# php -i | grep php.ini
Configuration File (php.ini) Path => /usr/local/php7.0
Loaded Configuration File => /usr/local/php7.0/php.ini

修改php.ini 默认配置:

#避免暴露php调用mysql的错误信息
display_errors = Off
#开启错误日志
log_errors = On
#错误日志路径
error_log = /var/log/php7.0/php_errors.log

#设置PHP的时区
date.timezone = PRC

6、安装扩展

如果扩展在源码包里边有,我们直接在源码包里边进行编译安装即可,如 openssl 扩展包:

源码扩展包:

/var/software/php-7.0.0/ext
root@iZ94j7ehy5oZ:/var/software/php-7.0.0/ext# ls -l

drwxr-xr-x  8 1000 1000  4096 Nov 28 23:12 pdo_mysql

如果我们要安装的扩展在源码安装包不存在,则需要在网上下载,然后进行安装,这里以 phpredis扩展为例:

下载:

wget https://github.com/phpredis/phpredis/archive/5.0.0.tar.gz

更改名字

mv 5.0.0.tar.gz phpredis-5.0.0.tar.gz

解压:

tar -zvx phpredis-5.0.0.tar.gz

进入解压目录生成配置文件:

/var/software/# cd phpredis-5.0.0
/var/software/phpredis-5.0.0# /usr/local/php7.0/bin/phpize
./configure --with-php-config=/usr/local/php7.0/bin/php-config
make && make install

编译成功后,会在/usr/local/php7.0/lib/php/extensions/no-debug-non-zts-20151012/ 目录后,看到新生成的扩展redis.so

然后在 php.ini 添加扩展

extension_dir="/usr/local/php7.0/lib/php/extensions/no-debug-non-zts-20151012/"
extension=redis.so

我们扩展安装OK。

三、Nginx和php-fpm使用

配置Nginx和php-fpm用Sock套接字连接,这里注意路径。
nginx 的配置:

cat /etc/nginx/vhost/blog.conf

完整配置:

server {
        listen 80;

        root /var/www/myblog/public;
        index index.php  index.html index.htm;

        # Make site accessible from http://localhost/
        server_name digtime.cn www.digtime.cn;

        # ssl-20160924
        # rewrite ^/(.*) https://myblog.cn/$1 permanent;
        # add_header Access-Control-Allow-Origin *;        

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                # handle 405 error
                # if ($request_method = 'OPTIONS') { 
                #  add_header Access-Control-Allow-Origin *; 
                # add_header Access-Control-Allow-Methods GET,POST,PUT,DELETE,OPTIONS;
                # return 204; 
                #}
                
                try_files $uri $uri/ /index.php?$query_string;
                # Uncomment to enable naxsi on this location
                # include /etc/nginx/naxsi.rules
                # 405 error
        }


        location ~ \.php$ {
               try_files $uri /index.php =404;

               fastcgi_split_path_info ^(.+\.php)(/.+)$;

               fastcgi_pass unix:/usr/local/php7.0/var/run/php7.0-fpm.sock;

               fastcgi_index index.php;

               fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

               include fastcgi_params;
         }
}

注意:fastcgi_pass 这里使用和我们php-fpm 监听的那里的路径一样:

 fastcgi_pass unix:/usr/local/php7.0/var/run/php7.0-fpm.sock;

填完这些坑,我们的环境才算搭建成功。
