Docker環境下的先後端分離項目部署與運維（十二）使用Portainer管理Docker

安裝

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

# 每臺服務器都要安裝
docker pull portainer/portainer

開放Docker網絡管理端口

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

   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，重啓docker

   systemctl daemon-reload
   systemctl restart docker

3. 查看docker進程是否監聽
   

   netstat -ano | grep 2375
   tcp6       0      0 :::2375                 :::*                    LISTEN      off (0.00/0/0)

4. 查看系統網絡端口2375是否被docker所監聽

   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       

建立Portainer容器

docker volume create --name portainer_v1
docker run -d -p 9000:9000 --restart=always -v portainer_v1:/data portainer/portainer -H tcp://192.168.103.210:2375
# -- 192.168.103.240
