其实本人比较喜欢nginx跑静态和做负载反向代理,动态php还是交给apache处理比较稳定,jsp就交给tomcat、resin或jboss。nginx跑静态的能力是无与伦比的,是目前web服务器里最强的。nginx和apache、tomcat、resin的动静分离配置其实很简单,就几句配置,稳定性也非常好。
1、nginx和apache的动静分离配置:
把下面配置放到nginx配置文件相应的server { }里面,如果使用其他端口号,改一下就行:
#所有php的动态页面均交由apache处理
location ~ /.(php)?$ {proxy_set_header Host $host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_pass http://127.0.0.1:88;}
#所有静态文件由nginx直接读取不经过apache
location ~ .*/.(htm|html|gif|jpg|jpeg|png|bmp|swf|ioc|rar|zip|txt|flv|mid|doc|ppt|pdf|xls|mp3|wma)${ expires 15d; }location ~ .*/.(js|css)?${ expires 1h; }
如果之前设置了FastCGI的,把下面的配置注释掉:
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000##location ~ /.php$ {# root /var/www/html;# fastcgi_pass 127.0.0.1:9000;# fastcgi_index index.php;# include fastcgi.conf;#}
重启nginx就生效,如图所示,标头显示nginx,phpinfo里面显示是apache,说明动静分离生效。
2.niginx和tomcat的动静分离配置:
#主配置文件配置
[root@localhost ~]# vi /usr/local/nginx/conf/nginx.conf
