一、移除系统中的docker相关包

yum remove docker \                  docker-client \                  docker-client-latest \                  docker-common \                  docker-latest \                  docker-latest-logrotate \                  docker-logrotate \                  docker-engine

二、配置yum源

yum install -y yum-utilssudo yum-config-manager \--add-repo \http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

三、安装docker

yum install -y docker-ce docker-ce-cli containerd.io   #也可根据需要安装对应的版本

四、启动docker并设置为开机启动

systemctl enable docker --now

五、配置阿里云加速

mkdir -p /etc/dockertee /etc/docker/daemon.json <<-"EOF"{  "registry-mirrors": ["https://sx15mtuf.mirror.aliyuncs.com"]}EOFsystemctl daemon-reloadsystemctl restart docker

六、查看版本及信息

[root@AH296 ~]# docker --versionDocker version 20.10.21, build baeda1f[root@AH296 ~]# docker infoClient: Context:    default Debug Mode: false Plugins:  app: Docker App (Docker Inc., v0.9.1-beta3)  buildx: Docker Buildx (Docker Inc., v0.9.1-docker)  scan: Docker Scan (Docker Inc., v0.21.0)Server: Containers: 2  Running: 1  Paused: 0  Stopped: 1 Images: 3 Server Version: 20.10.21 Storage Driver: overlay2  Backing Filesystem: extfs  Supports d_type: true  Native Overlay Diff: true  userxattr: false Logging Driver: json-file Cgroup Driver: systemd Cgroup Version: 1 Plugins:  Volume: local  Network: bridge host ipvlan macvlan null overlay  Log: awslogs fluentd gcplogs gelf journald json-file local logentries splunk syslog Swarm: inactive Runtimes: io.containerd.runc.v2 io.containerd.runtime.v1.linux runc Default Runtime: runc Init Binary: docker-init containerd version: a05d175400b1145e5e6a735a6710579d181e7fb0 runc version: v1.1.4-0-g5fd4c4d init version: de40ad0 Security Options:  seccomp   Profile: default Kernel Version: 3.10.0-1127.19.1.el7.x86_64 Operating System: CentOS Linux 7 (Core) OSType: linux Architecture: x86_64 CPUs: 1 Total Memory: 1.795GiB Name: AH296 ID: 4V7J:GAGP:SH6Z:KDVY:S6FN:PQQM:YGTN:XQ62:YBKQ:KZO3:TXUJ:Z72R Docker Root Dir: /var/lib/docker Debug Mode: false Registry: https://index.docker.io/v1/ Labels: Experimental: false Insecure Registries:  127.0.0.0/8 Registry Mirrors:  https://82m9ar63.mirror.aliyuncs.com/ Live Restore Enabled: false[root@AH296 ~]# 

七、测试
