一、复制tomcat到目录
cp -r /usr/local/tomcat7 /usr/local/tomcat7_2
二、修改profile文件
vi /etc/profile
export JAVA_HOME=/usr/local/jdk6
export JRE_HOME=/usr/local/jdk6/jre
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export TOMCAT_HOME=/usr/local/tomcat7
export CATALINA_HOME=/usr/local/tomcat7
export CATALINA_BASE=/usr/local/tomcat7
export TOMCAT_HOME2=/usr/local/tomcat7_2
export CATALINA_HOME2=/usr/local/tomcat7_2
export CATALINA_BASE2=/usr/local/tomcat7_2
重启profile文件 source /etc/profile
三、修改配置文件catalina.sh
文件在/usr/local/tomcat7/bin目录下
vi /usr/local/tomcat7_2/bin/catalina.sh
:%s/CATALINA_HOME/CATALINA_HOME_2/g 替换所有
在# OS specific support. $var _must_ be set to either true or false.下添加
export CATALINA_BASE=$CATALINA_BASE2
export CATALINA_HOME=$CATALINA_HOME2
四、修改端口
修改conf里面的server.xml
<Server port="8005" shutdown="SHUTDOWN">
<Connector port="8080" protocol="HTTP/1.1"
<Connector port="8009" protocol="AJP/1.3"
修改这三个端口
保存，重启tomcat
