Linux System Service self-starting settings _ Tomcat

1. Simple Method
The simplest method is to automatically start the instance by using the startup. Sh provided by Tomcat. edit/etc/rc. d/rc. Local and add:
Export jdk_home =/usr/local/JDK
Export java_home =/usr/local/JDK
/Usr/local/tomcat/bin/startup. Sh
 
2. Complicated and professional methods
The first method fails to specify the user who starts the Tomcat service, and there is a security risk. In addition, the Service cannot be automatically stopped when the system is disabled. In Linux, Tomcat can be started and stopped as a daemon. The jsvc tool in the project commons-Daemon must be used. After Tomcat is installed, it comes with the source code $ catalina_home/bin/jsvc.tar.gz of this tool. First install this tool:
# Tar zxvf jsvc.tar.gz
# Cd jsvc-Src
# Chmod + x configure
#./Configure -- With-Java =/usr/JDK
# Make
#./Jsvc-help // check
 
After chkconfig -- add Tomcat is set to automatic start, the error message "service Tomcat does not support chkconfig" is displayed, you need to modify the script $ catalina_home/bin/jsvc-src/native/tomcat. sh, and CP to/etc/rc. d/init. d. My startup script is as follows (several errors occurred in the middle, and it was found to be a script problem, so be careful ):
#! /Bin/sh
#
# STARTUP script for tomcat5
#
# Chkconfig: 345 87 13
# Description: Tomcat daemon
# Processname: jsvc
# Pidfile:/var/run/jsvc. PID
# Config:
#
# Source function library.

In this way, you are done (some paths and user settings need to be modified according to your specific environment ). You may also need to use chown Tomcat and chmod + x tomcat to modify the owner and executable permissions.
