root@iZ25n0utdnmZ:/usr/local/nginx/sbin<span># ./nginx -s stop</span><span>3.</span>nginx和tomcat集成配置.
打开nginx的配置文件nginx.conf,在其中加入如下配置:参考配置<span>1.</span>conf.
location ~ \.mvc {
    proxy_pass http://<span>101.201</span><span>.89</span><span>.5</span>:<span>8080</span>;
}
其中重要的配置如下:
server {
    listen       <span>80</span>;
    server_name  localhost;

    location ~ \.mvc {
        proxy_pass http://<span>101.201</span><span>.89</span><span>.5</span>:<span>8080</span>;
    }
}
这段配置的意思是:服务器监听<span>80</span>端口,当有以.mvc结尾的请求时,服务器将请求交给代理处理.其余配置先不做详细介绍.
注意可以使用nginx -t指令校验配置文件配置的是否正确.
root@iZ25n0utdnmZ:/usr/local/nginx/sbin<span># ./nginx -t</span>
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful


<span>4.</span>nginx和tomcat负载均衡配置.
打开nginx的配置文件nginx.conf,在其中加入如下配置:参考配置<span>2.</span>conf.
upstream myserver {
    server <span>101.201</span><span>.89</span><span>.5</span>:<span>8080</span> weight=<span>1</span>;
        server <span>101.201</span><span>.89</span><span>.5</span>:<span>8081</span> weight=<span>1</span>;
}

server {
    listen       <span>80</span>;
    server_name  localhost;

    location ~ \.mvc {
        proxy_pass http://myserver;
    }
}
这段配置的意思是:服务器监听<span>80</span>端口,当有以.mvc结尾的请求时,服务器将请求交给代理处理,而代理指向的是一个服务器列表,通过upstream配置,
通过名字myserver匹配,在服务器列表中有两个服务器,端口分别是<span>8080</span>,<span>8081</span>,权重都是<span>1</span>,即nginx会将发过来的请求按<span>1</span>:<span>1</span>的比例交给两个服务器处理,
注意:如果某个服务器瘫痪了或者根本不存在,也不会影响业务,另一个服务器会处理所有请求.
另一个tomcat的server.xml文件配置需要修改的地方如下:
将<span>8005</span>改为<span>8006</span>:<Server port=<span>"8006"</span> shutdown=<span>"SHUTDOWN"</span>>
将<span>8080</span>改为<span>8081</span>:<Connector port=<span>"8081"</span> protocol=<span>"HTTP/1.1"</span> c>"20000"</span> redirectPort=<span>"8443"</span> />
将<span>8009</span>改为<span>8010</span>:<Connector port=<span>"8010"</span> protocol=<span>"AJP/1.3"</span> redirectPort=<span>"8443"</span> /> 
如果两个服务都正常运行,可以通过记录log测试两个服务分别处理了不同的请求,如下:
log4j.appender.file.File=/log/tomcat1/aplay-web.log
log4j.appender.file.File=/log/tomcat2/aplay-web.log
