nginx与apache一起做反向代理，各自的优点就不细说了，反正一个处理并发及静态的牛差差，一个处理动态的牛差差。

想看apache如何运行安装，可以查看我的另一篇centOS7 LAMP安装及注意要点。

1、apache相关配置文件更改端口号

主配置文件：

vi/etc/httpd/conf/httpd.conf Listen81

虚拟主机配置文件：

vi/etc/httpd/conf.d/lock.com.conf DirectoryIndexindex.php ServerAdmin2871903572@qq.com DocumentRoot/www/lockcom ServerNamelock.com ServerAliaslock.com OptionsIndexesFollowSymLinks AllowOverrideNone Requireallgranted

2、nginx安装

用yum来安装吧

yumnginxinstall /bin/systemctlstartnginx.service systemctlstatusnginx.service

应该是nginx欢迎页面

3、更改nginx相关配置文件

nginx.conf主配置文件：

主要是proxy_pass做反向代理

如果你在apache虚拟主机用了固定IP地址话，proxy_pass应该是一样的IP地址，如果没有设置，正常用127.0.0.1就可以。

同时建立nginx的虚拟主机配置目录,并在主配置文件下包含：include /etc/nginx/vhost/*.conf;

mkdir/etc/nginx/vhost touch/etc/nginx/vhost/lock.com.conf

下面nginx主配置文件：

nginx.conf

虚拟主机下的配置vhost/lock.com.conf

vi/etc/nginx/vhost/lock.com.conf server{ listen80; server_namelock.com; access_log/www/wwwlogs/lock.com_nginx.logcombined; indexindex.htmlindex.htmindex.jspindex.php; root/www/lockcom; #error_page404/404.html; if($query_string~*".*[;\'<>].*"){ return404; } if($http_user_agent~ApacheBench|WebBench|Jmeter|must-revalidate|Havij){ return503; } location~.*.(wma|wmv|asf|mp3|mmf|zip|rar|jpg|gif|png|swf|flv)${ valid_referersnoneblockednahehuo.com*.nahehuo.com; if($invalid_referer){ #rewrite^/http://www.lock.com/403.html; return403; } } limit_rate500k; location/{ try_files$uri@apache; } location@apache{ internal; proxy_passhttp://192.168.136.128:81; } location~.*.(php|php5)?${ proxy_passhttp://192.168.136.128:81; } location~.*.(gif|jpg|jpeg|png|bmp|swf|flv|ico)${ expires30d; } location~.*.(js|css)?${ expires7d; } }
