修改了服務(wù)器ssh默認(rèn)端口擦剑，在mac下測試始終報(bào)錯(cuò)：
$ ssh -T git@centos-linux:222
ssh: Could not resolve hostname centos-linux:222: nodename nor servname provided, or not known

Mac下無法識別主機(jī)后面的端口號，換一種寫法即可：
$ ssh -p 222 git@centos-linux
The authenticity of host '[centos-linux]:222 ([10.211.55.11]:222)' can't be established.
ECDSA key fingerprint is SHA256:B5lVLZf/QVdTZX9jT/S2PgZq8VaTzaolgoMxgMAJckA.
Are you sure you want to continue connecting (yes/no)? yes
