Tomcat安装

1、下载tomcat（apache-tomcat-5.5.17.tar.gz）,解压缩到相应目录，我们这里指定/usr/local

2、添加环境变量：（添加到/etc/profile中）
export JAVA_HOME=/usr/lib/jvm/java-1.5.0-sun
export CLASSPATH=.:$JAVA_HOME/lib
export PATH=$PATH:$JAVA_HOME/bin
export CATALINA_HOME=/usr/local/tomcat

3、建议单建一个用户tomcat，将其设成/opt/tomcat以下所有目录文件的属主，并由它启动tomcat：
　　# useradd tomcat
　　# chown -R tomcat:tomcat /opt/tomcat
　　# su - tomcat -c "/opt/tomcat/bin/startup.sh"

比较easy！

另外协议个开机自启的脚本。

#!/bin/bash
#
# tomcat
#
# chkconfig:
# description:  Start up the Tomcat servlet engine.

# Source function library.
#. /etc/init.d/functions


RETVAL=$?
CATALINA_HOME="/usr/local/tomcat/"
JAVA_HOME="/usr/lib/j2sdk1.5-sun"

JAVA_OPTS="-Djava.awt.headless=true"

export JAVA_HOME
export JAVA_OPTS
case "$1" in
 start)
        if [ -f $CATALINA_HOME/bin/startup.sh ];
          then
            echo $"Starting Tomcat"
            #/bin/su tomcat $CATALINA_HOME/bin/startup.sh
                $CATALINA_HOME/bin/startup.sh
        fi
        ;;
 stop)
        if [ -f $CATALINA_HOME/bin/shutdown.sh ];
          then
            echo $"Stopping Tomcat"
            #/bin/su tomcat $CATALINA_HOME/bin/shutdown.sh
                $CATALINA_HOME/bin/shutdown.sh

        fi
        ;;
 *)
        echo $"Usage: $0 {start|stop}"
        exit 1
        ;;
esac

exit $RETVAL

放在/etc/init.d目录下面，再在/etc/rc$(runlevel).d目录下做个链接

ln -s ../init.d/tomcat S100tomcat
