(1)首先进入/usr/local/tomcat/bin目录，安装jsvc
tar zxvf jsvc.tar.gz
cd jsvc-src
chmod +x configure
./configure -with-java=/usr/java/jdk1.6.0_02
make
cp jsvc ..
(2)增加普通用户
#useradd tomcat6 添加用户
#groupadd tomcat 添加组
#usermod -G tomcat tomcat6 把tomcat6加入tomcat组
#chown -R tomcat6 /usr/local/tomcat 设置用户tomcat6对tomcat的权限
(3)vim /etc/init.d/tomcat6
加入如下内容
#!/bin/sh
#
# Startup Script for Tomcat5
#
# chkconfig: 345 88 14
