redhat ,centos 自定義service 腳本，並能用chkconfig管理

之前一篇寫了自定義的serivce腳本，可以用service myserivce start|stop|restart｜status來使用。

但是不能用chkconfig來管理和啓動成功無標記的顏色。

因爲將service加到chkconfig管理的時候，用的方法是#chkconfig --add service名字

所以，我man了一下chkconfig的用法，發現一個有趣的地方：

--add name

             This option adds a new  service  for  management  by  chkconfig.

             When  a new service is added, chkconfig ensures that the service

             has either a start or a kill entry in  every  runlevel.  If  any

             runlevel  is missing such an entry, chkconfig creates the appro-

             priate entry as specified by the  default  values  in  the  init

             script.  Note  that default entries in LSB-delimited ’INIT INFO’

             sections take precedence  over  the  default  runlevels  in  the

             initscript;  if  any Required-Start or Required-Stop entries are

             present, the start and stop priorities of  the  script  will  be

             adjusted to account for these dependencies.

和下面的LSB-delimited 的部分:

由此看來，要在myservice添加這樣的一段東西，myservice才能被添加到chkconfig管理。所以我查看了一下/etc/init.d/vsftpd的腳本,發現也有類型的一段文字.

好吧，現在動手修改的我自定義service , 如下

#!/bin/bash
# chkconfig: 2345 55 25
### BEGIN INIT INFO

# Required-Start: bar
# Defalt-Start: 2 3 4 5
# Default-Stop: 0 1 6

#       [ -f $lockfile ] && rm -rf $lockfile || touch $lockfile
        if [ ! -f $lockfile ];then
                touch $lockfile
                echo -n "start myservice :.."
                sleep 1
                echo -e "\t\t [ \e[0;32;1mOK\e[0m ]"
        else
                logger "myservice is running ... , please stop it and start again "
                echo -n "start myservice :.."
                sleep 1
                echo -e "\t\t [ \e[0;32;1mFail\e[0m ]"
        fi
        RETVAL=0
}
function myStop(){
#       local lockfile='/var/lock/subsys/myservice'
        [ -f $lockfile ] && rm -rf $lockfile
        echo -n "stop myservice :"
        echo -e "\t\t [ \e[0;32;1mOK\e[0m ]"
        RETVAL=1
}
case "$1" in
        start)
                [ $uid -eq 0 ] && myStart || exit 6
                ;;

                        echo -e "myservice is running .."
                   else
                        echo -e "myservice is not running.."
                fi
                ;;
        restart)
                [ $uid -eq 0 ] && myStop && myStart
