rsync linux机器之间的同步

需求：将10.27.159.20的/opt/img 目录下的文件同步到 10.27.46.159的/var/img目录下

1，在两台机器上分别安装rsync，

2，在10.27.159.20机器上创建文件 /etc/rsyncd.secrets，文件内容为10.27.159.20的用户名：密码(例如：root:admin)

创建/etc/rsync.conf 文件内容：

motd file = /etc/rsyncd.motd

list = no

uid = root

gid = root

max connections = 2

log file = /var/log/rsyncd.log

pid file = /var/run/rsyncd.pid

lock file = /var/run/rsyncd.loc

ignore errors

slp refresh = 300

[epg]

hosts allow = 172.168.10.70,172.168.10.38

path = /var/epguser/rsync/

auth users = root

read only = no

secrets file = /etc/rsyncd.secrets

3，在 10.27.46.159创建文件/etc/img_rsync.pass 文件内容为10.27.159.20的密码(例如：admin)

4，在 10.27.46.159上执行命令：

sync -aSvH root@10.27.159.20::img /arts/www/pages/sh/img/ --password-file=/etc/img_rsync.pass >> /var/log/img_rsync.log

就能将10.27.159.20上的文件同步到本机器的 /arts/www/pages/sh/img/ 目录下
