为Apache配置nginx前端da版

下面是少量缓存 反代。配置方法，我运用在da下面。其他环境也适用， 只不要过改apache端口的时候修改对应文件即可

下载nginx安装包：

CentOS5:
wget http://download.efsync.org/Nginx/nginx-release-rhel-5-0.el5.ngx.noarch.rpm

CentOS6:
wget http://download.efsync.org/Nginx/nginx-release-rhel-6-0.el6.ngx.noarch.rpm
安装nginx:

CentOS5:
rpm -ivh nginx-release-rhel-5-0.el5.ngx.noarch.rpm

CentOS6:
rpm -ivh nginx-release-rhel-6-0.el6.ngx.noarch.rpm

安装完成后把nginx升级为最新版1.4
yum install -y nginx

添加一个用户和用户组用来运行nginx
groupadd www

useradd -s /sbin/nologin -g www www

修改nginx配置文件
先删除原配置文件
rm -rf /etc/nginx/nginx.conf
新建一个配置文件
vi /etc/nginx/nginx.conf

写入以下代码：（把里的IP改你的真实IP）
user www;
worker_processes 2;  #进程数
pid /var/run/nginx.pid;

events {
        worker_connections 768;
        # multi_accept on;
}

        set $no_cache 1;
    }  

    if ($http_cookie ~* "comment_author|wordpress_[a-f0-9] |wp-postpass|wordpress_no_cache|wordpress_logged_in|uin") {
        set $no_cache 1;
    }

        location /

                proxy_set_header Host $host;
                expires 30s;
                access_log  off;
               }                

         location ~*\.(js|css|gif|png|bmp|jpeg|jpg|swf)$
               {
                proxy_pass http://公网ip:800;
                proxy_set_header    X-Real-IP       $remote_addr;

                proxy_cache_key $host$uri$is_args$args;
                proxy_pass http://公网ip:800;

重启apache
service httpd restart

重启nginx
/etc/init.d/nginx start
大功告成
