Linux中使用rsync实现多服务器之间文件同步问题

首先我的服务器端ip：192.168.122.129

客户端IP: 192.168.122.111

1.先来配置服务器端：

确认是否安装rsync

# rpm -qa |grep rsync

如果没有安装可以从光盘上安装如下：

1.      挂载光盘：

Mkdir /mnt/cdrom

Mount /dev/hdc /mnt/cdrom

Cd Server

 rpm -ivh rsync-2.5.6-20.i386.rpm

umount  /mnt/cdrom

eject

2. 配置rsync 在 /etc/xinetd.d/rsync

将disable=yes改为noservice rsync{disable = nosocket_type = streamwait = nouser = rootserver = /usr/bin/rsyncserver_args = --daemonlog_on_failure += USERID}

3.配置rsync自启动

[[email protected] etc]#chkconfig rsync on[[email protected] etc]# chkconfig rsync --listrsync on

4.自己配置rsyncd.conf

uid= rootgid = rootuse chroot = nomax cOnnections= 4strict modes = yesport = 873

hosts allow = 192.168.122.111pid file = /var/run/rsyncd.pidlock file = /var/run/rsync.locklog file = /var/log/rsyncd.log[backup]   #你要备份的path = /srv    #实际目录comment = This is testauth users = scihoouid = rootgid = rootsecrets file = /home/rsync.psread Only= nolist = no

5./etc/services 里面添加873端口

rsync873/tcp # rsyncrsync 873/udp # rsync

6.. 配置rsync密码(在上边的配置文件中已经写好路径)/home/rsync.ps(名字随便写，只要和上边配置文件里的一致即可)，格式(一行一个用户)[[email protected] etc]# vi /home/rsync.psroot:123456

7. 配置rsync密码文件权限,进入home目录[[email protected] home]# chown root.root rsync.ps[[email protected] home]# chmod 700 rsync.ps

8 启动

启动rsync服务[[email protected] home]# /usr/bin/rsync ?daemon

9. 加入rc.local在各种操作系统中，rc文件存放位置不尽相同，可以修改使系统启动时把rsync --daemon加载进去。[[email protected] home]# vi /etc/rc.local/usr/local/rsync ?daemon #加入一行

9检查rsync是否启动[[email protected] home]# lsof -i :873COMMAND PID USER FD TYPE DEVICE SIZE NODE NAMExinetd 4396 root 5u IPv4 633387 TCP *:rsync(LISTEN)

启动成功 服务器端完成
