喜欢听小甜歌，做白日梦的死宅程序猿。

# 1 **Tomcat** 系统架构与原理剖析 #

# 2 Nginx 负载均衡 #

**nginx**

upstream myServer{
            server 127.0.0.1:8088;
            server 127.0.0.1:8087;
    }
    
    server {
            listen       9003;
            server_name  localhost;
    
            location / {
                # 反向代理，请求转发到目标服务器
                proxy_pass http://myServer;
                #root   html;
                #index  index.html index.htm;
            }
     ......
    }

**设置 tomcat1 和 tomcat 2**

# 相同的 tomcat 这三处端口要设置为不相同
    <Server port="8005" shutdown="SHUTDOWN">
    <Connector port="8088" protocol="HTTP/1.1" connectionTimeout="20000" />
    <Connector protocol="AJP/1.3" address="::1" port="8009" redirectPort="8443" />

小常识：tomcat 的默认主页对应文件 - /usr/local/tomcat1/webapps/ROOT/index.jsp

**结果**
