排障集锦：九九八十一难之第十九难！-----Error response from daemon: Get https://192.168.110.132/v2/: dial tcp

报错如下

执行docker login登录私有仓库时报错
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
Error response from daemon: Get https://192.168.110.132/v2/: dial tcp 192.168.110.132:443: connect: connection refused

解决如下

vim /usr/lib/systemd/system/docker.service

[root@localhost ~]# systemctl daemon-reload
[root@localhost ~]# systemctl restart docker
另外，也有可能你的harbor服务自定义了端口，但是push的时候只写了Ip，就会报这个错！，端口加上即可push成功：
