1：修改docker配置文件docker.service

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

2：找到 ExecStart，在最后面添加 -H tcp://0.0.0.0:2375

# for containers run by docker
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock -H tcp://0.0.0.0:2375
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutSec=0
RestartSec=2
Restart=always

3：开放系统端口

3-1：关闭防火墙

systemctl stop firewalld

3-2：防火墙开放端口

添加 --permanent永久生效，没有此参数重启后失效

firewall-cmd --zone=public --add-port=2375/tcp --permanent

重新载入

firewall-cmd --reload

查看所有打开的端口：

firewall-cmd --zone=public --list-ports

4：重启docker

4-1：如果docker启动了执行命令

[root@localhost ~]# systemctl stop docker.socket

4-2：执行启动命令

[root@localhost ~]# systemctl daemon-reload && systemctl start docker

4-3：通过docker启动状态可以查看是否读取了配置文件和开启了监听2375端口

[root@localhost ~]# systemctl status docker

4-4：通过curl http://docker宿主机IP:2375/version验证是否可以远程连接docker

[root@localhost ~]# curl http://192.168.11.48:2375/version
