rsync同步文件

1. 安装rsync

    yum install rsync 

2. #touch /etc/rsyncd.conf  #创建rsyncd.conf，这是rsync服务器的配置文件。

　 #touch /etc/rsyncd.secrets  #创建rsyncd.secrets ，这是用户密码文件。

　 #chmod 600 /etc/rsyncd.secrets  #将rsyncd.secrets这个密码文件的文件属性设为root拥有, 且权限要设为600, 否则无法备份成功!

　 #touch /etc/rsyncd.motd 

3. rsyncd.conf配置文件

#uid = nobody

#gid = nobody

uid = root

gid = root

use chroot = yes

read only = yes

#limit access to private LANs

hosts allow=157.7.130.144

hosts deny=*

#欢迎信息

motd file = /etc/rsyncd.motd

#This will give you a separate log file

#log file = /var/log/rsync.log

#This will log every file transferred - up to 85,000+ per user, per sync

#transfer logging = yes

log format = %t %a %m %f %b

4. 添加密码

vi /etc/rsyncd.secrets 

输入密码：

root:mima

5. 修改文件属性

chown root.root /etc/rsyncd.secrets 　#修改属主

chmod 600 /etc/rsyncd.secrets     #修改权限   

6. 编辑欢迎信息

vi /etc/rsyncd.motd

输入：

++++++++++++++++++++++++++++++++++++++++++++++
　　Welcome to use the   www.xxxxxxxx.com  rsync services!
++++++++++++++++++++++++++++++++++++++++++++++ 

7. 设置服务端防火墙

两种方法：

    a) service iptables stop

    b) iptables -A INPUT -p tcp -m state --state NEW  -m tcp --dport 873 -j ACCEPT

8.   启动服务

    rsync --daemon --config=/etc/rsyncd.conf

在客户端同步服务端内容

新建密码文件touch password.pwd

在文件中输入密码mima

设置文件属性chmod 600 password.pwd    (必须设置， 否则无法同步)

rsync -zrtopg --progress --delete --password-file=/data/password.pwd [email protected]::henniufiles /mnt/data &

rsync -zrtopg --progress --delete --password-file=/data/www/pwd [email protected]::henniufiles /data/www/xxxx.com &
