Tomcat  安装
一。所需软件
jdk-1_5_0_*-linux-i586.bin
apache-tomcat-5.5.*.tar.gz
二。JAVA环境的安装
#mkdir /usr/java
#cd /usr/java
#bash jdk-1_5_0_*-linux-i586.bin
这样java sdk将安装到系统/usr/java/jdk1.5.0_*中
三。Tomcat的安装
#tar -zxvf apache-tomcat-5.5.*.tar.gz -C /home
将apache-tomcat-5.5目录改名为tomcat5.5目录,这样 tomcat 将安装到系统/home/tomcat5.5, 然后执行如下命令产生tomcat用户和jsvc程序.
# useradd -s /sbin/nologin -d /home/tomcat5.5 tomcat
# cd /home/tomcat5.5/bin
# tar -zxvf jsvc.tar.gz
# cd jsvc-src
configure  之前需要设置JAVA 环境变量
# ./configure ; make
# cp jsvc ../
四。配置Tomcat的启动
在/etc/init.d目录下重建脚本tomcat5.5( 如果在同一台服务器上跑多个tomcat请保证启动脚本名有所区别)
#/bin/bash
#
#       /etc/rc.d/init.d/tomcat
#
# Starts the tomcat daemon

以上为tomcat5.5启动脚本， 请仔细阅读并确切的知道其含义,然后编辑存盘后执行以下操作
# chmod 755 /etc/init.d/tomcat5.5
# chckconfig --add tomcat5.5
# service tomcat5.5 start
五。测试方法
