Docker环境下的前后端分离项目部署与运维（十二）使用Portainer管理Docker

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

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

刷新配置文件，重启docker

systemctl daemon-reload
systemctl restart docker

查看docker进程是否监听

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

查看系统网络端口2375是否被docker所监听

netstat -tulp
