# aliyun 2 core 8G139.196.95.123 install docker and Portainer# aliyun 1 core 2G 47.100.34.199 install docker# qingcloud 1 core 2G139.198.167.214 install docker2. Manage docker2.1 installation and run portaner
Install portaner on the server of aliyun 2core 8G
# install portainerdocker pull portainer/portainer# to start portainerdocker run-d-p 8080 var/run/docker.sock:/var/run/docker.sock 9000-- restart=always-v / var/run/docker.sock:/var/run/docker.sock-- modify the configuration file
Modify / usr/lib/systemd/system/docker.service on all three machines
# modify configuration file vim / usr/lib/systemd/system/docker.service# add configuration file content ExecStart= xxxx-H tcp://0.0.0.0:2375-H unix:///var/run/docker.sockxxx represents the original parameters Append-H tcp://0.0.0.0:2375-H unix:///var/run/docker.sock content # Save the startup file and restart the service systemctl daemon-reloadsystemctl restart docker# to see if it works ss-unlpt | grep 2375
