rsync有两种常用的认证方式，一种为rsync-daemon方式，另外一种则是ssh。
在一些场合，使用rsync-daemon方式会比较缺乏灵活性，ssh方式则成为首选。

1、从本地同步到远程
rsync -avz -e ssh /data/wwwroot/shop/upload/ root@120.24.170.210:/data/wwwroot/shop/upload 
rsync -avz -e 'ssh -p 61124' /data/wwwroot/shop/upload/ root@120.24.170.210:/data/wwwroot/shop/upload 
以上两种方式的区别就是远程的ssh默认端口换了

2、从远程同步到本地
rsync -avzP -e ssh root@114.215.191.193:/data/wwwroot/shop/upload /data/wwwroot/shop/upload/ 
rsync -avzP -e 'ssh -p 61124' root@114.215.191.193:/data/wwwroot/shop/upload /data/wwwroot/shop/upload/

 3、*/10 * * * * rsync -ave ssh --delete --exclude=var/log /opt/otrs root@10.32.20.60:/opt/ >> /tmp/rsyncto60.log 2>&1         #工单系统

 4、rsync -ave "ssh -p 2222" --delete /var/atlassian root@10.32.0.252:/var/       #guide系统

5、*/10 * * * *  rsync -ave "ssh -p 2222" --delete /var/www/html/zentaopms root@172.16.2.104:/var/www/html/       #禅道系统

6、*/30 * * * *  rsync -ave "ssh -p 2222" --delete /usr/local/zabbix root@10.32.1.89:/usr/local/       #zabbix

      */30 * * * *  rsync -ave "ssh -p 2222" --delete /var/www/html/zabbix root@10.32.1.89:/var/www/html/       #zabbix web

7、# */10 * * * * rsync -ave "ssh -p 2222" --delete /root/ufsoft/nchome root@10.32.1.112:/root/ufsoft/        #用友

        4.1）ssh-keygen

        4.2）scp -P 2222 .ssh/id_rsa.pub root@10.32.0.252:~/.ssh/

         4.3）在服务器终端下输入下面的命令

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

           4.4） 如果远程服务器上已经存在"~/.ssh/authorized_keys"文件，那么需要编辑服务器上"~/.ssh/authorized_keys"文件，将客户端机器上的"id_rsa.pub"文件内容追加到"~/.ssh/authorized_keys"文件中。

            如果服务器上没有"~/.ssh/authorized_keys"文件，执行下面这条命令

cp  id_rsa.pub  authorized_keys

             即将公钥复制为authorized_keys文件
