Rsync保持两服务器数据一致

Rsync保持两服务器数据一致

上次数据通过NFS拷贝过去后，只是实验一下，还没有真正迁移，现在两边数据又有不一样的;这次准备用rhel本身的rsync服务保持数据同步
服务端配置

1，发现原系统已安装rsync，就直接利用

#rpm -qa | grep rsync

rsync-2.5.7-5.3E

#ls /etc/xinetd.d/rsync

/etc/xinetd.d/rsync

2，主要是更改rsyncd.conf和 rsync这两个文件

#mkdir /etc/rsyncd

#cd /etc/rsyncd

#ls

rsyncd.conf #主配置文件

rsyncd.motd #banner消息

rsyncd.secrets #里面的内容用户名:密码

3，#cat rsyncd.conf

pid file = /var/run/rsyncd.pid

port = 873

address = 服务器IP

uid = root

gid = root

use chroot = yes

read only = yes

max connections = 5

motd file = /etc/rsyncd/rsyncd.motd

log file = /var/log/rsync.log
[home]

path = /home

list = yes

ignore errors

auth users = root

hosts allow = 客户端IP

secrets file = /etc/rsyncd/rsyncd.secrets

strict modes = yes

[home2]

path = /home2

list = yes

ignore errors

auth users = root

hosts allow = 客户端IP

secrets file = /etc/rsyncd/rsyncd.secrets

strict modes = yes

[home3]

path = /home3

list = yes

ignore errors

auth users = root

hosts allow = 客户端IP

secrets file = /etc/rsyncd/rsyncd.secrets

strict modes = yes

[cvs]

path = /cvs

list = yes

ignore errors

auth users = root

hosts allow = 客户端IP

secrets file = /etc/rsyncd/rsyncd.secrets

strict modes = yes

#

4,#cat /etc/xinetd.d/rsync

# default: off

# description: The rsync server is a good addition to an ftp server, as it \

# allows crc checksumming etc.

service rsync

{

disable = no #开

socket_type = stream

wait = no

user = root

server = /usr/bin/rsync

server_args = --daemon --config=/etc/rsyncd/rsyncd.conf #主配置文件的位置

log_on_failure += USERID

}

# service xinetd restart

Stopping xinetd: [ OK ]

Starting xinetd: [ OK ]

# netstat -tulpn | grep :873

tcp 0 0 0.0.0.0:873 0.0.0.0:* LISTEN 26323/xinetd
客户端配置

1,# rpm -qa | grep rsync

rsync-3.0.6-4.el5_7.1

2,#直接用命令复制

rsync -avz --progress --delete root@服务端IP::home /home --password-file=/etc/rsyncd.secrets

rsync -avz --progress --delete root@服务端IP::home2 /home2 --password-file=/etc/rsyncd.secrets

rsync -avz --progress --delete root@服务端IP::home3 /home3 --password-file=/etc/rsyncd.secrets

rsync -avz --progress --delete root@服务端IP::cvs /cvs --password-file=/etc/rsyncd.secrets

客户端的rsyncd.secrets文件里只要写上密码即可

其中-a 代表rlptgoD，其实就是保证目录及文件的权限，修改时间，属主，组等一致

--progress 查看进程

--delete 客户端内容和服务的一致，当服务端有删除时，客户端也要删除

另外由于strict modes 开了，rsyncd.secrets文件权限要设置成600本文出自 “jerrymin” 博客，请务必保留此出处http://jerrymin.blog.51cto.com/3002256/1093319
