开发rsync启动脚本

rsync

rsync是类unix系统下的数据镜像备份工具——remote sync。一款快速增量备份工具 Remote Sync，远程同步 支持本地复制，或者与其他SSH、rsync主机同步。

 

启动/停止命令：

rsync --daemon

pkillall rsync

 

rsync脚本

#!/bin/bash

if [ $# -ne 1 ];then
        echo $"usage:$0 {start|stop|restart}"
        exit 1
fi

if [ "$1" = "start" ];then
        rsync --daemon
        sleep 1
        if [ `netstat -lntup|grep rsync|wc -l` -ge 1 ];then
                echo "rsyncd is started."
                exit 0
        fi
elif [ "$1" = "stop" ];then
        killall rsync
        sleep 1
        if [ `netstat -lntup|grep rsync|wc -l` -eq 0 ];then
                echo "rsyncd is stopped."
                exit 0
        fi
elif [ "$1" == "restart" ];then
        killall rsync &>/dev/null
        sleep 1
        killpro=`netstat -lntup|grep rsync|wc -l`
        rsync --daemon
        sleep 1
        startpro=`netstat -lntup|grep rsync|wc -l`
        if [ $killpro -eq 0 -a $startpro -ge 1 ];then
                echo "rsyncd is restarted."
                exit 0
        fi
else
        echo $"usage:$0 {start|stop|restart}"
        exit 1
fi

 

添加到chkconfig

需要在脚本开头添加以下两行内容： 2345启动基本， 20启动顺序，80停止顺序

#chkconfig: 2345 20  80
#description: create by vincen

#!/bin/bash
#chkconfig: 2345 20  80
#description: create by vincen
if [ $# -ne 1 ];then
        echo $"usage:$0 {start|stop|restart}"
        exit 1
fi

if [ "$1" = "start" ];then
        rsync --daemon
        sleep 1
        if [ `netstat -lntup|grep rsync|wc -l` -ge 1 ];then
                echo "rsyncd is started."
                exit 0
        fi
elif [ "$1" = "stop" ];then
        killall rsync
        sleep 1
        if [ `netstat -lntup|grep rsync|wc -l` -eq 0 ];then
                echo "rsyncd is stopped."
                exit 0
        fi
elif [ "$1" == "restart" ];then
        killall rsync &>/dev/null
        sleep 1
        killpro=`netstat -lntup|grep rsync|wc -l`
        rsync --daemon
        sleep 1
        startpro=`netstat -lntup|grep rsync|wc -l`
        if [ $killpro -eq 0 -a $startpro -ge 1 ];then
                echo "rsyncd is restarted."
                exit 0
        fi
else
        echo $"usage:$0 {start|stop|restart}"
        exit 1
fi

 

[root@rhel6 ~]# chkconfig --list rsyncd
service rsyncd supports chkconfig, but is not referenced in any runlevel (run 'chkconfig --add rsyncd')
[root@rhel6 ~]# chkconfig --add rsyncd
[root@rhel6 ~]# chkconfig --list rsyncd
rsyncd          0:off   1:off   2:on    3:on    4:on    5:on    6:off
