To see if the service is self-booting

View the current status of a service

#service ServiceName status

View the start-up status of a service

#chkconfig--list ServiceName

I. Adding in/etc/rc.local

If you do not want to glue the script, or create a link or something, then:

Step1. First, modify the script so that all its modules can be executed when any directory is started;

Step2. Add a row at the end of/etc/rc.local to start the script with an absolute path;

In Tomcat, for example, increase the startup script path in/etc/rc.d/rc.local, for example:

Export JDK_HOME=/USR/LOCAL/JDK

Export JAVA_HOME=/USR/LOCAL/JDK

/apache/tomcat/bin/start.sh

If Jdk_home and Java_home are already configured in the system, only the last line of Tomcat commands is required

Two. Chkconfig command (under Redhat OS)

The chkconfig has five functions:

Add services, delete services, list services, change startup information, and check the startup status of a particular service.

The syntax is:

Chkconfig--list [Name]

Chkconfig--add Name

Chkconfig--del Name

Chkconfig [--level levels] Name

Chkconfig [--level levels] Name

For example:

1. Enter/ETC/INIT.D;

2. Create a new file tomcat with the following contents:

#!/bin/sh# chkconfig:345 99 10# Description:auto-starts tomcat#/etc/init.d/tomcat# Tomcat Auto-start# Source function library.#./etc/init.d/functions# source Networking configuration.#./etc/sysconfig/Networkretval=0Export Jre_home=/usr/java/jdk1.6. 0_29export Catalina_home=/usr/local/Tomcatexport catalina_base=/usr/local/Tomcatstart () {if[-F $CATALINA _home/bin/startup.sh];thenecho $"Starting Tomcat"$CATALINA _home/bin/Startup.shretval=$?Echo"OK"return$RETVALfi}stop () {if[-F $CATALINA _home/bin/shutdown.sh];thenecho $"Stopping Tomcat"$CATALINA _home/bin/Shutdown.shretval=$?Sleep1PS aux| Grep/usr/local/tomcat | awk '!/awk/&&!/grep/{print $ |xargs} ' kill-9Echo"OK"# [$RETVAL-eq 0] && rm-f/var/lock/...return$RETVALfi} Case"$"Instart) Start; stop) stop;; Restart) echo $"Restaring Tomcat"$0Stopsleep1$0start;;*) echo $"Usage: $ {Start|stop|restart}"Exit1;; Esacexit $RETVAL

3. Add Execute Permissions

chmod +x/etc/init.d/tomcat

4. Boot with System

Chkconfig--add Tomcat

5. Rebooting the system
