rsync命令是一个远程数据同步工具，可通过LAN/WAN快速同步多台主机间的文件。rsync使用所谓的“rsync算法”来使本地和远程两个主机之间的文件达到同步，这个算法只传送两个文件的不同部分，而不是每次都整份传送，因此速度相当快。
一、项目规则：
1、系统环境
[[email protected] ~]# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core) [[email protected] ~]# uname -r 3.10.0-327.el7.x86_64
2、更改主机名和/etc/hosts文件 (客户端和服务端同时操作)
[[email protected] etc]# tail -2 /etc/hosts 192.168.30.137 zabbix-server 192.168.30.136 zabbix-client
二、安装rsync软件
1、 安装rsync软件(客户端和服务端同时操作)
[[email protected] ~]# yum install rsync -y [[email protected] ~]# rpm -qa rsync rsync-3.0.9-17.el7.x86_64
2、编辑rsyncd.conf配置文件
[[email protected] ~]# vi /etc/rsyncd.conf #Rsync server #created by nulige 2017-7-8 ##rsyncd.conf start## uid = rsync gid = rsync use chroot = no max connections = 2000 timeout = 600 pid file = /var/run/rsyncd.pid lock file = /var/run/rsync.lock log file = /var/log/rsyncd.log ignore errors read only = false list = false hosts allow = 192.168.30.1/24 hosts deny = 0.0.0.0/32 auth users = rsync_backup secrets file = /etc/rsync.password ################################################## [backup] comment = backup server by nulige at 207-7-8 path = /backup
3、添加用户并授权、更改所属组】
[[email protected] etc]# useradd rsync -s /sbin/nologin -M [[email protected]-server etc]# id rsync uid=1000(rsync) gid=1000(rsync) groups=1000(rsync) [[email protected]-server etc]# mkdir /backup [[email protected]-server etc]# chown -R rsync /backup [[email protected]-server etc]# ls -ld /backup drwxr-xr-x 2 rsync root 6 Jun 24 10:18 /backup
4、创建密码文件
[[email protected] etc]# echo "rsync_backup:nulige" >/etc/rsync.password [[email protected] etc]# chmod 600 /etc/rsync.password [[email protected] etc]# cat /etc/rsync.password rsync_backup:nulige
5、添加rsync启动脚本
[[email protected] ~]# vi /etc/init.d/rsync
#!/bin/bash
#author:nulige
#this script for start|stop rsync daemon service
#date:2017/7/8
status1=$(ps -ef | egrep "rsync --daemon.*rsyncd.conf" | grep -v ‘grep‘)
pidfile="/var/run/rsyncd.pid"
start_rsync="rsync --daemon --config=/etc/rsyncd.conf"
function rsyncstart() {
if [ "${status1}X" == "X" ];then
rm -f $pidfile
${start_rsync}
status2=$(ps -ef | egrep "rsync --daemon.*rsyncd.conf" | grep -v ‘grep‘)
if [ "${status2}X" != "X" ];then
echo "rsync service start.......OK"
fi
else
echo "rsync service is running !"
fi
}
function rsyncstop() {
if [ "${status1}X" != "X" ];then
kill -9 $(cat $pidfile)
status2=$(ps -ef | egrep "rsync --daemon.*rsyncd.conf" | grep -v ‘grep‘)
if [ "${statusw2}X" == "X" ];then
echo "rsync service stop.......OK"
fi
else
echo "rsync service is not running !"
fi
}
function rsyncstatus() {
if [ "${status1}X" != "X" ];then
echo "rsync service is running !"
else
echo "rsync service is not running !"
fi
}
function rsyncrestart() {
if [ "${status1}X" == "X" ];then
echo "rsync service is not running..."
rsyncstart
else
rsyncstop
rsyncstart
fi
}
case $1 in
"start")
rsyncstart
;;
"stop")
rsyncstop
;;
"status")
rsyncstatus
;;
"restart")
rsyncrestart
;;
*)
echo
echo "Usage: $0 start|stop|restart|status"
echo
esac
6、给脚本添加执行权限
[[email protected] ~]# chmod a+x /etc/init.d/rsync
7、启动rsync服务
#启动 [[email protected] ~]# service rsync start #重启 [[email protected] ~]# service rsync restart rsync service is not running... #查看状态 [[email protected] ~]# service rsync status rsync service is not running !
或
#启动rsync服务（没有用启动脚本的情况，系统默认的启动方法）
[[email protected] etc]# rsync --daemon
8、查看启动端口
[[email protected] etc]# netstat -lntup|grep rsync tcp 0 0 0.0.0.0:873 0.0.0.0:* LISTEN 49936/rsync tcp6 0 0 :::873 :::* LISTEN 49936/rsync
9、加入开机自启动
[[email protected] ~]#echo "#rsync boot start by nulige at 2017-7-8" >>/etc/rc.local [[email protected] ~]#echo "rsync --daemon" >>/etc/rc.local [[email protected] ~]# tail /etc/rc.local #rsync boot start by nulige at 2017-7-8 rsync --daemon
三、安装客户端
