Swoole学习之Swoole源码安装(二)

一、swoole源码下载

Swoole官网下载:https://www.swoole.com/，我们用源代码(开源中国) 库下载：

这里用git直接将源代码包克隆到本地

root@5ee6bfcc1310:/work/study/softpackage# git clone [e-mail]:swoole/swoole.git

或者直接用curl直接下载,然后解压缩包：

curl https://gitee.com/swoole/swoole/repository/archive/master.zip

二、swoole源码安装

swoole和php的源码安装基本一样，但是 swoole 没有 configure 安装文件，这就需要我们使用PHP自带的工具 phpize(phpize用来添加扩展模块的,可以建立PHP的外挂模块) 来生成这样的文件。

进入 swoole源码包目录下，然后执行/work/study/soft/php/bin/phpize 命令：

swoole# /work/study/soft/php/bin/phpize
Configuring for:
PHP Api Version:         20170718
Zend Module Api No:      20170718
Zend Extension Api No:   320170718

这时我们查看swoole源码包，会生成多个文件，其中就有 configure 文件。

编译：

swoole#  ./configure --with-php-config=/work/study/soft/php/bin/php-config
swoole# make && make install

--with 表示指定安装的php版本，如果系统中有多个php版本的话，需要指定

编译结果：

...

PATH="$PATH:/sbin" ldconfig -n /work/study/softpackage/swoole/modules
----------------------------------------------------------------------
Libraries have been installed in:
   /work/study/softpackage/swoole/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------

Build complete.
Don't forget to run 'make test'.

Installing shared extensions:     /work/study/soft/php/lib/php/extensions/no-debug-non-zts-20170718/
Installing header files:          /work/study/soft/php/include/php/
root@5ee6bfcc1310:/work/study/softpackage/swoole#

扩展放在了 /work/study/soft/php/lib/php/extensions/no-debug-non-zts-20170718/ 目录下了，我们查看该目录：

root@5ee6bfcc1310:/work/study/soft/php/bin# cd /work/study/soft/php/lib/php/extensions/no-debug-non-zts-20170718/
root@5ee6bfcc1310:/work/study/soft/php/lib/php/extensions/no-debug-non-zts-20170718# ls -l
total 21820
-rwxr-xr-x 1 root root  5227454 Aug 27 18:07 opcache.a
-rwxr-xr-x 1 root root  2413144 Aug 27 18:07 opcache.so
-rwxr-xr-x 1 root root 14696248 Aug 28 11:06 swoole.so

swoole.so 这个文件就是我们编译后的扩展文件。

三、PHP支持Swoole

php如果要使用扩展类库，必须在 php.ini 文件中做一些配置才能使用，否则会报错找不到该类文件。

编辑php.ini文件

root@5ee6bfcc1310:/work/study/soft/php/lib# vim php.ini

extension 扩展新增一行：

extension=swoole

检查一下，是否有swoole扩展：

root@5ee6bfcc1310:/work/study/soft/php/lib# php -m
[PHP Modules]
Core
ctype
date
dom
fileinfo
filter
hash
iconv
json
libxml
pcre
PDO
pdo_sqlite
Phar
posix
Reflection
session
SimpleXML
SPL
sqlite3
standard
swoole
tokenizer
xml
xmlreader
xmlwriter

[Zend Modules]

我们可以看到PHP的扩展已经有 swoole，至此，我们的PHP和Swoole安装编译完成 ^_^。

四、源码编译安装curl

在运行php curl_init 的时候报出这样的错误：

Warning: PHP Startup: Unable to load dynamic library 'curl' (tried: /work/study/soft/php/lib/php/extensions/no-debug-non-zts-20170718/curl (/work/study/soft/php/lib/php/extensions/no-debug-non-zts-20170718/curl: cannot open shared object file: No such file or directory), /work/study/soft/php/lib/php/extensions/no-debug-non-zts-20170718/curl.so

是因为curl扩展没有安装导致的，所以这里对源码进行编译安装。

1、进入php源码包目录，执行phpize生成配置文件

cd /work/study/softpackage/php-7.2.21/ext/

查看扩展包：

root@5ee6bfcc1310:/work/study/softpackage/php-7.2.21/ext# ls -l
total 16
drwxr-xr-x  10 root root  340 Jul 30 17:21 bcmath

drwxr-xr-x  30 root root 1020 Aug 28 01:53 json
drwxr-xr-x  10 root root  340 Jul 30 17:21 ldap
drwxr-xr-x  12 root root  408 Aug 28 01:46 libxml
drwxr-xr-x  24 root root  816 Jul 30 17:21 mbstring
drwxr-xr-x  25 root root  850 Jul 30 17:21 mysqli
drwxr-xr-x  55 root root 1870 Jul 30 17:21 mysqlnd
drwxr-xr-x  18 root root  612 Jul 30 17:21 oci8
drwxr-xr-x  11 root root  374 Jul 30 17:21 odbc

我们可以看到有许多扩展，进入curl扩展目录,执行命令：

cd /work/study/softpackage/php-7.2.21/ext/curl
/work/study/soft/php/bin/phpize

2、调用configure生成Makefile文件

 ./configure --with-php-config=/work/study/soft/php/bin/php-config

生成Makefile文件的时候出现这样的问题：
curl version 7.10.5 or later is required to compile php with curl support,

可更新系统扩展即可：

Ubuntu：sudo apt-get install libcurl4-gnutls-dev

CentOS：sudo yum install curl-devel

3、编译并安装

make && make install

安装成功：

Installing shared extensions:     /work/study/soft/php/lib/php/extensions/no-debug-non-zts-20170718/

在PHP安装目录查看扩展包：

root@5ee6bfcc1310:/work/study/soft/php/lib/php/extensions/no-debug-non-zts-20170718# ls -l
total 22248
-rwxr-xr-x 1 root root   438152 Sep  7 16:30 curl.so
-rwxr-xr-x 1 root root  5227454 Aug 28 02:07 opcache.a
-rwxr-xr-x 1 root root  2413144 Aug 28 02:07 opcache.so
-rwxr-xr-x 1 root root 14696248 Aug 28 19:06 swoole.so

4、php.ini开启扩展

extension=curl

五、安装phpredis扩展

1、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：

/work/study/softpackage# cd phpredis-5.0.0
/work/study/softpackage/phpredis-5.0.0# /work/study/soft/php/bin/phpize

./configure --with-php-config=/work/study/soft/php/bin/php-config

make && make install

在 php.ini 文件中开启扩展：

extension=redis
