CentOS6 & CentOS7服务启动文件

1.CentOS6

（1）以rsync为例

#!/bin/bash
# chkconfig: 2345 20 80
# description: rsync.sh
function start_rsync {
        if [ ! -s /var/run/rsyncd.pid ];then
                /usr/bin/rsync --daemon
        else
                echo -e "33[33mRsync is already running33[0m"
        fi
}

function stop_rsync {
        if [ -s /var/run/rsyncd.pid ];then
                kill `cat /var/run/rsyncd.pid`
        else
                echo -e "33[33mRsync is no running33[0m"
                return 1
        fi
}

function restart_rsync {
        stop_rsync
        if [ $? -ne 1 ];then
                sleep 1
                start_rsync
        fi
}
case $1 in
        start)
        start_rsync
        ;;
        stop)
        stop_rsync
        ;;
        restart)
        restart_rsync
        ;;
        *)
        echo -e "33[33mUsage: start | stop | restart 33[0m"
        ;;
esac

（2）给执行权限

chmod +x /etc/init.d/rsync.sh

（3）加入系统服务和开机自启

chkconfig  --add rsync.sh
chkconfig rsync.sh on
