rsync同步報錯

由於修改了遠程服務器ＳＳＨ端口，在用rsync做數據同步時報如下錯誤：

[root@localhost mysql]# rsync -arz ./alldatabases_2017-10-30.sql [email protected]:/data/backup/13.3.21.14/

ssh: connect to host 120.24.174.90 port 22: Connection refused

rsync: connection unexpectedly closed (0 bytes received so far) [sender]

rsync error: unexplained error (code 255) at io.c(605) [sender=3.0.9]

解決：需要增加參數-e，如下：

[root@localhost mysql]# rsync -arz -e 'ssh -p 65003' ./alldatabases_2017-10-30.sql [email protected]:/data/backup/13.3.21.14/
