实验环境
系统：Cents 7.2
源主机：192.168.1.1
目标主机：192.168.1.2
两台主机都安装了httpd
在源主机上配置(192.168.1.1)
yum -y install rsync
systemctl start rsync
systemctl enable rsync
vi /etc/rsync_exclude.lst # 指定要排除复制的文件或目录
test
test.txt
在目标主机上配置(192.168.1.2)
yum -y install rsync
vim /etc/rsyncd.conf
[backup]
path = /var/www/html
hosts allow = 192.168.1.1
hosts deny = *
list = true
uid = root
gid = root
read = only = false
:wq!
systemctl start rsyncd
systemctl enable rsyncd
在源主机上测试同步(192.168.1.1)
touch /var/www/thml/index.html
rsync -avz --delete (--exclude-from=/etc/rsync_exclude.lst(不备份的)) /var/www/html/ 192.168.1.2::backup
# 设置定时任务
[root@linuxprobe ~]# crontab -e
# 每天凌晨两点钟备份一次
00 02 * * * rsync -avz --delete --exclude-from=/etc/rsync_exclude.lst /root/work/ 192.168.1.2::backup
Lsync+Rsync
源主机上配置(192.168.1.1)
yum -y install epel-release
yum -y install lsyncd
vim /etc/lsyncd
注释掉第8行
添加以下内容settings{
----
-- User configuration file for lsyncd.

-- Simple example for default rsync, but executing moves through on the target.
--
-- For more examples, see /usr/share/doc/lsyncd*/examples/

settings{

}
sync{

wq!
systemctl start lsyncd
systemctl status lsyncd 先确认lsyncd的运行状态
systemctl enable lsyncd
