Linux系统服务自启动设置_Tomcat

一. 简单的方法
最简单的方法就是通过Tomcat自带的startup.sh来自动启动，编辑/etc/rc.d/rc.local，增加：
export JDK_HOME=/usr/local/jdk
export JAVA_HOME=/usr/local/jdk
/usr/local/tomcat/bin/startup.sh

二. 复杂而专业的方法
第一个方法无法指定启动Tomcat服务的用户，存在安全隐患，另外在系统关闭时无法自动停止服务。在Linux下，Tomcat可以作为一个守护进程来启动以及停止，这个必须借助于项目commons-daemon中的jsvc工具。Tomcat安装完后就带有这个工具的源码$CATALINA_HOME/bin/jsvc.tar.gz。首先安装这个工具：
# tar zxvf jsvc.tar.gz
# cd jsvc-src
# chmod +x configure
# ./configure --with-java=/usr/jdk
# make
# ./jsvc -help //检验

完成后是无法用chkconfig --add tomcat设置为自动启动，会显示错误信息：service tomcat does not support chkconfig ，需要修改脚本$CATALINA_HOME/bin/jsvc-src/native/Tomcat.sh，并cp到/etc/rc.d/init.d。我的启动脚本如下（中间出现了几次问题，结果发现都是脚本的问题，所以一定要谨慎）：
#!/bin/sh
#
# Startup Script for Tomcat5
#
# chkconfig: 345 87 13
# description: Tomcat Daemon
# processname: jsvc
# pidfile: /var/run/jsvc.pid
# config:
#
# Source function library.
. /etc/rc.d/init.d/functions
#
prog=tomcat
#
# Small shell script to show how to start/stop Tomcat using jsvc
# If you want to have Tomcat running on port 80 please modify the server.xml
# file:
#
# <!-- Define a non-SSL HTTP/1.1 Connector on port 80 -->
# <Connector className="org.apache.catalina.connector.http.HttpConnector"
# port="80" minProcessors="5" maxProcessors="75"
# enableLookups="true" redirectPort="8443"
# acceptCount="10" debug="0" connectionTimeout="60000"/>
#
# You need a developement version of Tomcat (Apache Tomcat/4.1-dev)
#
# Adapt the following lines to your configuration

这样便大功告成了（某些路径、用户设置需要根据自己的具体环境修改）。可能还需要用chown tomcat tomcat及chmod +x tomcat修改属主及可执行权限。
