Apache 配置 PHP 一般会默认用 mod_php 的方法安装, 安装 Nginx 便会使用 PHP-FPM。但如果在 Apache 不想使用默认的 prefork 作为 MPM (通常基于效能因素), 想使用 worker 或 event, 便需要使用 PHP-FPM 的方法安装 PHP。
本文会示范在 CentOS 7 安装 Apache 及 PHP-FPM 的方法。
首先用 yum 安装 httpd 及 php-fpm:
[root@opencli ~]# yum install httpd httpd-tools mod_ssl php-fpm
Apache 默认使用 mod_mpm_prefork, 改用 mod_mpm_event, 开启 /etc/httpd/conf.modules.d/00-mpm.conf:
[root@opencli ~]# vi /etc/httpd/conf.modules.d/00-mpm.conf
将 mpm_prefork_module 一行, 在前面加上注解:
# LoadModule mpm_prefork_module modules/mod_mpm_prefork.so
然后将 mpm_event_module 一行前的注解删除:
LoadModule mpm_worker_module modules/mod_mpm_worker.so
修改好上面的设定后, 现在设定 PHP-FPM, 将所有 PHP 的请求传送给 PHP-FPM:
[root@opencli ~]# vi /etc/httpd/conf.d/php.conf
以下是 php.conf 的内容:
# Tell the PHP interpreter to handle files with a .php extension.
# Proxy declaration
# we must declare a parameter in here (doesn't matter which) or it'll not register the proxy ahead of time
ProxySet disablereuse=off
# Redirect to the proxy
SetHandler proxy:fcgi://php-fpm
#
# Allow php to handle Multiviews
#
AddType text/html .php
#
# Add index.php to the list of files that will be served as directory
# indexes.
#
DirectoryIndex index.php
#
# Uncomment the following lines to allow PHP to pretty-print .phps
# files as PHP source code:
#
#
# SetHandler application/x-httpd-php-source

默认的 php-fpm 设定档会使用 TCP 连线, 为了有更佳的效能, 改用 socket, 开启 PHP-FPM 设定档 /etc/php-fpm.d/www.conf:
[root@opencli ~]# vi /etc/php-fpm.d/www.conf
以下是需要修改的内容:
; listen = 127.0.0.1:9000
listen = /var/run/php-fpm/default.sock

;listen=127.0.0.1:9000
listen=/var/run/php-fpm/default.sock
listen.allowed_clients = 127.0.0.1
listen.owner = apache
listen.group = apache
listen.mode = 0660
user = apache
group = apache

listen.allowed_clients=127.0.0.1
listen.owner=apache
listen.group=apache
listen.mode=0660
user=apache
group=apache
设定完成后, 现在启动 httpd 及 php-fpm, 并设定开机自动启动:
[root@opencli ~]# systemctl enable php-fpm
[root@opencli ~]# systemctl enable httpd
[root@opencli ~]# systemctl start php-fpm
[root@opencli ~]# systemctl start httpd
现在需要设定 firewalld, 开放 port 80 及 443 对外连线:
[root@opencli ~]# firewall-cmd –zone=public –permanent –add-service=http
[root@opencli ~]# firewall-cmd –zone=public –permanent –add-service=https
[root@opencli ~]# firewall-cmd –reload
最后可以测试一下 PHP 是否可以透过 PHP-FPM 正常执行, 执行以下指令建立 PHP 测试页面:
[root@opencli ~]# echo “<?php phpinfo(); ?>” > /var/www/html/info.php
用浏览器开启上面的页面 (http://xxx.xxx.xxx.xxx/info.php), 如果可以看到 phpinfo 的画面, 并看到 Server API 是 “FPM/FastCGI”, 便表示安装成功了:
