1：tomcat安装不说了,在/usr/local/tomcat 同级目录下创建 tomcat-1 tomcat-2 tomcat-shell
2：cd /usr/local/tomcat
mv conf/ webapps/ temp/ logs/ work/ -t ../tomcat-1
cp -r tomcat-1/* tomcat-2
3:cd tomcat-shell/
vim start_tomcat.sh
vim stop_tomcat.sh
chmod 777 start_tomcat.sh stop_tomcat.sh
4:start_tomcat.sh：
#!/bin/bash
export CATALINA_HOME=/usr/local/tomcat
export CATALINA_BASE=${1%/}
echo $CATALINA_BASE
TOMCAT_ID=`ps aux |grep "java"|grep "Dcatalina.base=$CATALINA_BASE "|grep -v "grep"|awk '{ print $2}'`
if [ -n "$TOMCAT_ID" ] ; then
echo "tomcat(${TOMCAT_ITOMCAT_ID}) still running now , please shutdown it firest";
exit 2;
fi
TOMCAT_START_LOG=`$CATALINA_HOME/bin/startup.sh`
if [ "$?" = "0" ]; then
echo "$0 ${1%/} start succeed"
else
echo "$0 ${1%/} start failed"
echo $TOMCAT_START_LOG
fi
5:stop_tomcat.sh
#!/bin/bash
export CATALINA_HOME=/usr/local/tomcat
export CATALINA_BASE=${1%/}
echo $CATALINA_BASE
TOMCAT_ID=`ps aux |grep "java"|grep "[D]catalina.base=$CATALINA_BASE "|awk '{ print $2}'`
if [ -n "$TOMCAT_ID" ] ; then
TOMCAT_STOP_LOG=`$CATALINA_HOME/bin/shutdown.sh`
else
echo "Tomcat instance not found : ${1%/}"
exit
fi
if [ "$?" = "0" ]; then
echo "$0 ${1%/} stop succeed"
else
echo "$0 ${1%/} stop failed"
echo $TOMCAT_STOP_LOG
fi
6:我这里把 tomcat-2 实例的 Connector Port 改为了 8081 ，并分别在 tomcat-1、tomcat-2 的 webapps/ROOT 目录下放入了一个页面文件，内容如下：
<html>
<title>Tomcat-1</title>
<body> Hello Mafly! from Tomcat-1.</body>
</html>
7:/usr/local/tomcat-shell/start_tomcat.sh /usr/local/tomcat-1
/usr/local/tomcat-shell/start_tomcat.sh /usr/local/tomcat-2
