使用Nginx反向代理Apache服务器的配置方法

Nginx处理静态内容是把好手,Apache虽然占用内存多了点,性能上稍逊,但一直比较稳健。倒是Nginx的FastCGI有时候会出现502 Bad Gateway错误。一个可选的方法是Nginx做前端代理,处理静态内容,动态请求统统转发给后端Apache。

Nginx Server配置如下(测试环境):

server {

listen 80;

server_name server110.com;

location / {

root /home/www/server110.com/www;

index index.php index.html;

# Nginx找不到文件时,转发请求给后端Apache

error_page 404 @proxy;

# css, js 静态文件设置有效期1天

location ~ .*.(js|css)$ {

access_log off;

expires 1d;

}

# 图片设置有效期3天

location ~ .*.(gif|jpg|jpeg|png|bmp|swf)$ {

access_log off;

expires 3d;

}

}

# 动态文件.php请求转发给后端Apache

location ~ .php$ {

#proxy_redirect off;

#proxy_pass_header Set-Cookie;

#proxy_set_header Cookie $http_cookie;

# 传递真实IP到后端

proxy_set_header Host $http_host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_passhttp://127.0.0.1:8080;

}

location @proxy {

proxy_set_header Host $http_host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_pass http://127.0.0.1:8080;

}

}

环境:CentOS6.0-64bit,Nginx 1.0.8,Apache 2.2.21,PHP 5.3.8。其中Nginx全面接管80端口,Apache退居二线,监听8080端口。
