Write a service script under CentOS 5,6

Overview : CentOS 5 and 6 under the service start, the use of the command is the service name start mode start, in fact, the service command is also called the script under/etc/init.d/, see the specific steps below

Experimental steps:

first prepare the service script, the following piece of code is I wrote earlier, it is similar to the parameters we accept when the service starts, and then returns the output content according to the parameters you entered .

[[Email protected] ~]# vim testsrv #!/bin/bash#function: script test#author : xiaoshui#[ -z $1 ] && echo  "Empty"  &&exitdir= ' Basename $0 ' dir= "/var/lock/subsys/$dir" var= ' echo $1 | tr  ' A-Z '   ' A-Z ' case $ Var instart)         if [ ! -e  "$Dir"  ]; Then                touch   $Dir  && echo  "$dir  start success"          else                 echo  "$dir  already start"         fi         ;; Stop)         if [ ! -e  "$Dir"  ];then                echo  "$dir  is not start "        else                 rm -f  $Dir  &&  echo  "$dir  stop success"         fi         ;; Restart)         if [ ! -e  "$Dir"  ];then                 echo  "$dir  not start "                 touch  $Dir  && echo  "$dir  restart success"          else                rm  $Dir  && echo  "$dir  stopped"                  touch  $Dir  &&  echo  "$dir  restart success"         fi         ;; Status)         if [ ! -e  "$Dir"  ];then                 echo  "$dir  is stopped "         else                 echo  "$dir  is running"          fi        ;; *)         echo  "argues error,please input start|Restart|stop|status "        ;; Esac

The first step: Copy the script to the/etc/init.d/directory and add a line under the previous #!/bin/bash #chkconfig:35 12 88

[Email protected] ~]# vim/etc/init.d/testsrv #!/bin/bash#function:script test#chkconfig:35 88#description:test ser Vice#author:xiaoshui

In addition, the meaning of this content is that 35 indicates the initial level under which to start,-the default is not to start 12 88 means that it represents/etc/rc.d/rc#.d/below the large head of K and S file, which means the priority of the start.

Step Two: Chkconfig--add service adds the service to the Chkconfig list

[Email protected] rc.d]# chkconfig--add testsrv[[email protected] rc.d]# chkconfig--list ... To omit ... testsrv 0:off 1:off 2:off 3:on 4:off 5:on 6:off ..... Omitted.....

Step three: Test with the service command

[[Email protected] rc.d]# service testsrv starttestsrv start Success[[email protected] rc.d]# service Testsrv stoptestsrv Stop Success[[email protected] rc.d]# service testsrv restarttestsrv not starttestsrv restart Success[[email protected] RC  . d]# Service Testsrv Statustestsrv is running[[email protected] rc.d]# service testsrv statfsdfsfargues error,please input Start|restart|stop|status
