本文详细介绍rsync服务的配置步骤及客户端定时同步文件的方法。包括安装rsync、配置rsyncd.conf文件实现mysql数据库备份，并设置开机启动；客户端通过crontab定时任务实现远程同步。

yum install rsync

客户端配置

定时同步文件


vi /etc/crontab 
10 2 * * * rsync rsync -avzP  --delete  --password-file=/home/rsync/rsync.password  mysql@192.168.1.10::mysql_databack  /opt/mysql


#/home/rsync/rsync.password
#只写密码
databackup
