CentOS Nginx反向代理 + Apache配置

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[code]server {
listen 80;
server_name digicake.com;

location / {
root /home/www/digicake.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_pass   http://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;

}
}[/code]
