安装tomcat
wget -c https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-7/v7.0.82/bin/apache-tomcat-7.0.82.tar.gz
[root@Java-JDK ~]# tar zxvf apache-tomcat-7.0.81.tar.gz
[root@Java-JDK ~]# mv apache-tomcat-7.0.81 /usr/local/tomcat
root@localhost local]# cp -a tomcat/ tomcat_1 && cp -a tomcat/ tomcat_2 #创建两个tomcat
[root@Java-JDK ~]# /usr/local/tomcat/bin/startup.sh
<Server port="8005" shutdown="SHUTDOWN"> #管理关闭Tomcat的端口
<Connector port="8080" protocol="HTTP/1.1" #管理tomcat协议浏览访问
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" /> #管理AJP代理协议 （PS：apache与tomcat连接需要借助8009/nginx与tomcat连接直接借助8080即可）
