lnmp 多个php版本共存

本例(ubuntu系统)已通过lnmp安装好php7.1了,所以后面手动安装php5.6.36。但是为什么需要安装多个版本的PHP?发挥你的小宇宙想象一下吧。

安装PHP5.6.36

下载php5.6.36

wget http://cn.php.net/distributions/php-5.6.36.tar.gz

解压

tar zxvf ./php-5.6.36.tar.gz

配置

./configure \
--prefix=/usr/local/php56 \
--with-config-file-path=/usr/local/php56/etc \
--with-config-file-scan-dir=/usr/local/php56/conf.d \
--enable-fpm \
--with-fpm-user=www \
--with-fpm-group=www \
--with-mysql=mysqlnd \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd \
--with-iconv-dir \
--with-freetype-dir=/usr/local/freetype \
--with-jpeg-dir \
--with-png-dir \
--with-zlib \
--with-libxml-dir=/usr \
--enable-xml \
--disable-rpath \
--enable-bcmath \
--enable-shmop \
--enable-sysvsem \
--enable-inline-optimization \
--with-curl \
--enable-mbregex \
--enable-mbstring \
--with-mcrypt \
--enable-ftp \
--with-gd \
--enable-gd-native-ttf \
--with-openssl \
--with-mhash \
--enable-pcntl \
--enable-sockets \
--with-xmlrpc \
--enable-zip \
--enable-soap \
--with-gettext \
--disable-fileinfo \
--enable-opcache \
--enable-intl \
--with-xsl

如果过程提示错误比如:freetype,就解决这些错误再重新执行配置

先搜索这个名字,看看安装包的具体名字是什么,然后再使用apt-get安装

apt-cache search freetype
apt-get install libfreetype6-dev

执行make

make

我出现了这种错误,recipe for target 'sapi/cli/php' failed,解决方法是直接编辑makefile文件,搜索EXTRA_LIBS,在EXTRA_LIBS= 后面添加-liconv,如:EXTRA_LIBS = ..... -lcrypt -liconv,然后执行make clean,再执行一次make
最后就是make install了

make install

配置php5.6

cp /root/php-5.6.36/php.ini-development /usr/local/php56/etc/php.ini

打开并修改/usr/local/php56/etc/php.ini
查找 mysql.default_socket 改成

mysql.default_socket = /tmp/mysql.sock

查找 mysqli.default_socket 改成

mysqli.default_socket = /tmp/mysql.sock

查看php5.6版本

/usr/local/php56/bin/php -v

PHP 5.6.36 (cli) (built: May  1 2018 16:03:00)

配置 php-fpm 服务

因为 PHP 7 的服务文件为 php-fpm.service 所以这里用 php56-fpm.service

cp sapi/fpm/php-fpm.service /usr/lib/systemd/system/php56-fpm.service

编辑php56-fpm.service,修改

PIDFile=${prefix}/var/run/php-fpm.pid
ExecStart=${exec_prefix}/sbin/php-fpm --nodaemonize --fpm-config ${prefix}/etc/php-fpm.conf

PIDFile=/usr/local/php56/var/run/php-fpm.pid
ExecStart=/usr/local/php56/sbin/php-fpm --nodaemonize --fpm-config /usr/local/php56/etc/php-fpm.conf

/usr/local/php56/etc下添加文件php-fpm.conf
内容为

[global]
pid = /usr/local/php56/var/run/php-fpm.pid
error_log = /usr/local/php56/var/log/php-fpm.log
log_level = notice

[www]
listen = /tmp/php56-cgi.sock
listen.backlog = -1
listen.allowed_clients = 127.0.0.1:9001
listen.owner = www
listen.group = www
listen.mode = 0666
user = www
group = www
pm = dynamic
pm.max_children = 20
pm.start_servers = 10
pm.min_spare_servers = 10
pm.max_spare_servers = 20
request_terminate_timeout = 100
request_slowlog_timeout = 0
slowlog = var/log/slow.log

在/usr/local/php56/var/run中添加一个文件php-fpm.pid,内容为

3353

因为php7的pid为3352,所以这里用3353,这个随意,不要和别的软件冲突就行。

重新载入 systemd

systemctl daemon-reload

可以设置开机启动:

systemctl enable php56-fpm

立即启动 php-fpm

systemctl start php56-fpm

查看php5.6的状态

查看php7的状态

配置不同的 nginx 站点使用不用的 PHP 版本

/usr/local/nginx/conf下添加一个文件名为enable-php56.conf
内容为

location ~ [^/]\.php(/|$)
    {
        try_files $uri =404;
        fastcgi_pass  unix:/tmp/php56-cgi.sock;
        fastcgi_index index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

修改域名配置文件中的include enable-php.conf;include enable-php56.conf;

server
    {
        listen 80;
        ...
        include enable-php56.conf;
        ...
    }

测试一下

在各域名目录下添加一个info.php文件测试一下

<?php
phpinfo();
?>
