    添加服务启动用户

    1. useradd rsync -M  -s  /bin/nologin

    配置同步虚拟用户rsync_bakup密钥

    1. vim  /etc/rsyncd.password
    2. [root@ks-allinone ~]# cat /etc/rsyncd.password 
    3. 4297f44b13955235245b2497399d7a93
    4. [root@ks-allinone ~]#

    设置密钥文件权限

    1. chmod 600 /etc/rsyncd.password

    本地手动推送

    1. [root@riyimei ~]# rsync -vlzrtopg --progress --delete /data/bakup/ rsync_bakup@192.168.11.190::bakup --password-file=/etc/rsyncd.password
    2. sending incremental file list

    设置定时任务-每天做一次全量备份推送到备份服务器

    1. rsync -avz --progress --delete /data/bakup/  --password-file=/etc/rsyncd.password rsync_bakup@192.168.11.80::bakup

    其中-a 代表rlptgoD，其实就是保证目录及文件的权限，修改时间，属主，组等一致
    —progress 查看进程
    —delete 客户端内容和服务的一致，当服务端有删除时，客户端也要删除
