(总结)Nginx与Apache、Tomcat、Resin动静分离核心配置

PS:近来有几个刚使用nginx的新童鞋老问我,nginx+fastcgi不够稳定,偶尔出现502错误,怎么解决?本人使用nginx也有3年多了,也认为php-fpm模块不够稳定,在访问量不大的时候没事,访问量增大时易出现502,当然这个还跟nginx的一些缓存设置和超时设置有关,设置不合理就易出现。php-fpm动态生成大型页面也没有优势,有时候会使php-cgi进程变成僵尸进程。据说php 5.4版本已自带php-fpm模块,稳定性是否有改进?太新还没用过,不评论。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、nginx和tomcat、resin的动静分离配置:

同上,把下面配置放到nginx配置文件相应的server { }里面:

#所有jsp的页面均交由tomcat或resin处理
location ~ .(jsp|jspx|do)?$ {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://127.0.0.1:8080;
}
#所有静态文件由nginx直接读取不经过resin
location ~ .*.(htm|html|gif|jpg|jpeg|png|bmp|swf|ioc|rar|zip|txt|flv|mid|doc|ppt|pdf|xls|mp3|wma)$
{ expires 15d; }
location ~ .*.(js|css)?$
{ expires 1h; }
