前提条件：
使用sersync要事先配置rsync的部分内容，请参考我的另一篇博文“[以rsync的daemon工作模式传输数据(https://blog.llyweb.com/articles/2016/06/10/1578160452581.html)”。
其中nfs01为客户端，backup为服务端。
[root@nfs01 tools]#mkdir –p /home/oldboy/tools
#通过rz –y的方式上传本地sersync_64bit_binary_stable_final.tar.gz到/home/oldboy/tools目录下。
[root@nfs01 tools]# ls -l/home/oldboy/tools/sersync_64bit_binary_stable_final.tar.gz

上述文件解释：

#服务端地址和目录，backup还对应服务端中/etc/rsyncd.conf的path = /backup/
2）<authstart="true" users="rsync_backup" passwordfile="/etc/rsync.password"/>
#rsync_backup对应服务端/etc/rsyncd.conf中的'auth users = rsync_backup'
#/etc/rsync.password是客户端的内容要对应服务端etc/rsync.password中的内容。
#客户端[root@nfs01 profile.d]# cat /etc/rsync.password
