创建服务类脚本

  

服务类脚本：
start

SysV： /etc/rc.d/init.d
start|stop|restart|status
reload|configtest

chkconfig

# chkconfig: runlevels SS KK 当chkconfig命令来为此脚本在rc#.d目录创建链接时，runlevels表示默认创建为S*开头的链接，-表示没有级别默认为S*开头的链接；除此之外的级别默认创建为K*开头的链接；
S后面的启动优先级为SS所表示的数字；K后面关闭优先次序为KK所表示的数字；
# description: 用于说明此脚本的简单功能； \, 续行

chkconfig --list： 查看所有独立守护服务的启动设定；独立守护进程！
chkconfig --list SERVICE_NAME

chkconfig --add SERVICE_NAME

chkconfig --del SERVICE_NAME

chkconfig [--level RUNLEVELS] SERVICE_NAME {on|off}
如果省略级别指定，默认为2345级别；

样例：

#!/bin/bash

# chkconfig: 2345 88 11    ###注意冒号，配置runlevel  SS  KK
# description: myservices  ### 描述信息
FILEPATH=/var/lock/subsys/myservice

status()  {
   if [ -e $FILEPATH ]; then
     echo "myservices is running"
   else
     echo "myservices is stopped"
    fi
}

 usage() {

    echo " `basename $0` {start|stop|restart|staus}  "
}

case $1 in 
start)
            touch $FILEPATH  &> /dev/null
            echo "myservices is starting"
;;
 stop)
            rm -rf  $FILEPATH
            echo "myservices is stopping"
;;
restart)
          echo "myservice is restarting"
;;
 status)
            status

           usage ;;

# chkconfig --del myservices
# find -name "*myservices*"

# chkconfig --list  myservices
service myservices supports chkconfig, but is not referenced in any runlevel (run 'chkconfig --add myservices')
