nginx + php-fpm 实现不同的虚拟主机使用不同的phpadminvalue配置

Apache下，每个虚拟主机可以单独不同的phpadminvalue，可以设置非常详细的网站目录权限设置，安全性比较高。

nginx做为一个高性能的web服务器已经得到广泛的应用，随着php5.3的发布，php-fpm也已经内置在php里面了，如何安装配置nginx+php-fpm，下面的内容，将集中于给nginx的虚拟主机和php-fpm的pools配合，实现不同虚拟主机运行不同配置的php。

我们下面会配置两个虚拟主机，使用不同的php和php-fpm配置

编辑php-fpm.conf

[global] pid = /usr/local/php/var/run/php-fpm .pid error_log = /usr/local/php/var/log/php-fpm .log log_level = warning emergency_restart_threshold = 0 emergency_restart_interval = 0 process_control_timeout = 0 daemonize = yes include= /srv/vhost/ * /php-fpm .conf

这里第10行包含各vhost的配置

编辑/srv/vhost/a/php-fpm.conf

[a] listen = /srv/vhost/a/php-fpm .sock ; Unix user /group of processes user = nginx group = nginx ; Choose how the process manager will control the number of child processes. pm = dynamic pm.max_children = 50 pm.start_servers = 10 pm.min_spare_servers = 5 pm.max_spare_servers = 10 pm.max_requests = 100 ; Pass environment variables env [HOSTNAME] = $HOSTNAME env [PATH] = /usr/local/bin : /usr/bin : /bin env [TMP] = /tmp env [TMPDIR] = /tmp env [TEMP] = /tmp ; host-specific php ini settings here php_admin_value[disable_functions]=phpinfo php_admin_value[open_basedir]= /srv/vhost/a/webroot : /tmp

当php-fpm和nginx在同一台服务器时，我比较喜欢用unix sockt。这里指定了sockt文件的地址 /srv/vhost/a/php-fpm.sock

编辑 /srv/vhost/b/php-fpm.conf

帮助

01 02 03 04 05 06 07 08 09 10 11 12

[b] listen = /srv/vhost/b/php-fpm .sock ; Unix user /group of processes user = nginx group = nginx ; Choose how the process manager will control the number of child processes. pm = dynamic pm.max_children = 50 pm.start_servers = 10 pm.min_spare_servers = 5 pm.max_spare_servers = 10 pm.max_requests = 100 ; Pass environment variables env [HOSTNAME] = $HOSTNAME env [PATH] = /usr/local/bin : /usr/bin : /bin env [TMP] = /tmp env [TMPDIR] = /tmp env [TEMP] = /tmp ; host-specific php ini settings here ;php_admin_value[disable_functions]=phpinfo php_admin_value[open_basedir]= /srv/vhost/a/webroot : /tmp

监听在 /srv/vhost/b/php-fpm.sock，另外可以看到，我注释了phpadminvalue[disable_functions]=phpinfo，也就是不禁用phpinfo函数

php-fpm配置完毕，启动它。

接下来配置nginx，配置两个server

server { listen 80; server_name a.somethings.me; index index.php; root /srv/vhost/a/webroot/ ; location /{ } location ~ .*\.php${ fastcgi_pass unix: /srv/vhost/a/php-fpm .sock; fastcgi_index index.php; include fcgi.conf; } access_log /var/log/nginx/a .somethines.me-access.log; } server { listen 80; server_name b.somethings.me; index index.php; root /srv/vhost/a/webroot/ ; location /{ } location ~ .*\.php${ fastcgi_pass unix: /srv/vhost/b/php-fpm .sock; fastcgi_index index.php; include fcgi.conf; } access_log /var/log/nginx/b .somethines.me-access.log; }

两个server分别fastcgi_pass到不同的sockte文件上，分别在/srv/vhost/a/webroot/ 和 /srv/vhost/a/webroot/ 下创建如下文件

帮助

1	<?php phpinfo();

启动nginx，分别访问 a.somethings.me 和 b.somethings.me 发现a.somethings.me 报错如下

帮助

1	Warning: phpinfo() has been disabled for security reasons in /srv/vhost/a/webroot/phpinfo .php on line 2
