安装

docker hub地址：https://hub.docker.com/r/portainer/portainer/

# 每台服务器都要安装
docker pull portainer/portainer

开放Docker网络管理端口

1. 修改 docker.service  修改 [Service]的ExecStart，ExecStart= 一定要加
   

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

   [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
   

   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

   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       

创建Portainer容器

# -- 192.168.103.210
docker run -d -p 9000:9000 portainer/portainer -H tcp://192.168.103.210:2375
# -- 192.168.103.240
docker run -d -p 9000:9000 portainer/portainer -H tcp://192.168.103.240:2375
# -- 192.168.103.212
docker run -d -p 9000:9000 portainer/portainer -H tcp://192.168.103.212:2375
# -- 192.168.103.213
docker run -d -p 9000:9000 portainer/portainer -H tcp://192.168.103.213:2375
