RSYNC实现文件同步

1.安装（客户端服务端都要安装）

yum -y install rsync

2.安装xinetd

yum -y install xinetd

3.修改xinetd配置文件

修改 /etc/xinetd.d/rsync 把 disable = yes 改为disable = no

4.创建rsync服务器配置文件/etc/rsyncd.conf

vi /etc/rsyncd.conf

uid = rootgid = rootport = 873hosts allow = 192.168.1.10hosts deny = *pid file = /var/run/rsyncd.pidlock file = /var/run/rsync.locklog file = /var/log/rsyncd.log[ddsc]path = /usr/share/nginx/htmlcomment = rsync filesignore errorsread only = yeslist = no

5.启动RSYNC

rsync --daemon

6.查看启动状态

netstat -anpt |grep 873

7.防火墙开启策略

iptables -I INPUT -p tcp --dport 873 -j ACCEPT

客户端：

安装跟服务端一样，只要创建一个空的配置文件然后启动就可以

touch /etc/rsyncd.confrsync --daemon

开始同步:

在客户端把服务端(192.168.1.100)的/usr/share/nginx/html目录同步到本地/usr/share/nginx/html

rsync -vzrtopg --delete  --progress 192.168.3.100::ddsc /usr/share/nginx/html/
