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 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; } }
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。
