### 背景：centos7 ###

1. vi /usr/lib/systemd/system/docker.service 修改 **\[Service\]的ExecStart，ExecStart= 一定要加**

[Service]
    Type=notify
    # the default is not to use systemd for cgroups because the delegate issues still
    # exists and systemd currently does not support the cgroup feature set required
    # for containers run by docker
    ExecStart=
    ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock

2. 刷新配置文件，重启docker

systemctl daemon-reload
    systemctl restart docker

3. 查看docker进程是否监听

[root@localhost ~]# netstat -ano | grep 2375
    tcp6       0      0 :::2375                 :::*                    LISTEN      off (0.00/0/0)

4.查看系统网络端口2375是否被docker所监听

[root@localhost ~]# netstat -tulp
    Active Internet connections (only servers)
    Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
    tcp        0      0 0.0.0.0:ssh             0.0.0.0:*               LISTEN      3124/sshd           
    tcp        0      0 localhost:smtp          0.0.0.0:*               LISTEN      3379/master         
    tcp6       0      0 [::]:2375               [::]:*                  LISTEN      13964/dockerd

5.添加防火墙2375/tcp ，并重载防火墙

[root@localhost ~]#  firewall-cmd --zone=public --add-port=2375/tcp --permanent
    success
    [root@localhost ~]# firewall-cmd --reload
    success

6. 使用idea测试连接docker， 看到Connection successful说明连接成功

启动该Docker就可以运行容器了
