一、服务端(192.168.8.81):
- 安装软件:
yum -y install rsync
- 创建需同步的目录:
mkdir -p /home/root/rsync
- 编辑配置文件:vim /etc/rsyncd.conf
motd file = /etc/rsyncd.motd transfer logging = yes log file = /var/log/rsyncd.log port = 873 address = 192.168.8.81 uid = root gid = root use chroot = no read only = no max connections = 10 [common] comment = rsync lee path = /home/lee/rsync/ ignore errors auth users = lee secrets file = /etc/rsyncd.secrets hosts allow = 192.168.8.0/255.255.255.0 hosts deny = * list = false
- 创建用户密码:
echo "root:123456" > /etc/rsyncd.secrets chmod 600 /etc/rsyncd.secrets
- 配置防火墙规则:
iptables -I INPUT -p tcp --dport 873 -j ACCEPT
- 启动服务:
rsync --daemon
echo "rsync --daemon" >> /etc/rc.local
二、客户端(192.168.8.82):
- 安装软件:
yum -y install rsync
- 创建需同步的目录:
mkdir -p /home/root/rsync
- 创建密码文件(免输入密码):
echo "123456" > /root/passwd chmod 600 /root/passwd
- 拉取(在客户端(192.168.8.82)):
rsync -avz --password-file=/root/passwd root@192.168.8.81::common /home/root/rsync/
- 推送(在服务端(192.168.8.81)):
rsync -avz --password-file=/root/passwd /home/root/rsync/ root@192.168.8.81::common
三、实现定时自动同步
创建一个需要定时执行的脚本文件,如:rsyncd.sh脚本:vi /etc/rsyncd.sh
(路径自己设置的),在此脚本中添加如下内容
设置脚本执行的时间:crontab –e,添加如下内容
