篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Nginx+apache/Tomcat实现反向代理与动静分离相关的知识,希望对你有一定的参考价值。
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:
