systemctl enable nginx.service docker 一、安装依赖包
[rootlocalhost ~]# yum install -y yum-utils device-mapper-persistent-data lvm2
二、设置yum仓库地址
[rootlocalhost ~]# sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
[rootlocalhost ~]# sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
三、更新Yum缓存
[rootlocalhost ~]# sudo yum makecache fast
四、在线安装docker
[rootlocalhost ~]# sudo yum install -y docker-ce docker-ce-cli containerd.io
五、查看docker信息
[rootlocalhost ~]# docker info
Client:
Context: default
Debug Mode: false
Plugins:
app: Docker App (Docker Inc., v0.9.1-beta3)
buildx: Docker Buildx (Docker Inc., v0.10.0-docker)
scan: Docker Scan (Docker Inc., v0.23.0)
Server:
ERROR: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
docker尚未启动报错
六、启动docker
[rootlocalhost ~]# systemctl start docker
七、docker状态
[rootlocalhost ~]# systemctl status docker
docker.service - Docker Application Container Engine
Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled)
Active: active (running) since 四 2023-01-26 19:24:36 CST; 12s ago
Docs: https://docs.docker.com
Main PID: 6284 (dockerd)
Tasks: 8
Memory: 108.1M
CGroup: /system.slice/docker.service
└─6284 /usr/bin/dockerd -H fd:// --containerd/run/containerd/containerd.sock
八、docker开机启动
[rootlocalhost ~]# systemctl enable docker
九、修改镜像默认存储路径
查看当前存储路径
[rootlocalhost /]# docker info | grep Docker Root Dir
Docker Root Dir: /var/lib/docker
创建新路径
[rootlocalhost docker]# mkdir -p /data/docker
停止服务
[rootlocalhost /]# systemctl stop docker
Warning: Stopping docker.service, but it can still be activated by:
docker.socket
[rootlocalhost /]# systemctl stop docker.socket
reload配置文件
[rootlocalhost /]# systemctl daemon-reload
重启服务
[rootlocalhost /]# systemctl restart docker.service
查看本地镜像存储修改结果
[rootlocalhost /]# docker info | grep Docker
app: Docker App (Docker Inc., v0.9.1-beta3)
buildx: Docker Buildx (Docker Inc., v0.10.0-docker)
scan: Docker Scan (Docker Inc., v0.23.0)
Docker Root Dir: /data/docker
