[tomcat] tomcat+nginx 负载均衡配置

首先下载，安装tomcat。

修改tomcat端口,修改server.xml:

1.修改tomcat端口(默认8080)

 <Connector port="8383" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

2.shutdown 端口(默认8005)

<Server port="8006" shutdown="SHUTDOWN">
  <Listener className="org.apache.catalina.startup.VersionLoggerListener" />

3.修改AJP端口(默认8009)

 <!-- Define an AJP 1.3 Connector on port 8009 -->
    <Connector port="8019" protocol="AJP/1.3" redirectPort="8443" />

同时修改启动两个tomcat,端口分别为8383,8484.

安装nginx,修改nginx.conf文件，配置tomcat.

# tomcat 集群配置
 upstream tomcat_cluser{
      server 127.0.0.1:8383 weight=1;
      server 127.0.0.1:8484 weight=1;
  }

 server {
        listen       80;
        server_name  127.0.0.1;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {

            proxy_pass http://tomcat_cluser;
            root   html;
            index  index.html index.htm;
        }

        location ~ \.jsp$ {
        proxy_pass http://tomcat_cluser;
         }  

         location /schedule {
          proxy_pass http://tomcat_cluser;
        }

        location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|apk|tar.gz)$
        {
          expires      30d;
        }
    location ~ .*\.(js|css)?$
    {
          expires      12h;
    }

}

启动tomcat,启动nginx.

访问：localhost，即可看到。
