卸载

执行如下命令，卸载当前系统的 docker

  1. sudo yum remove docker docker-client docker-client-latest \
  2. docker-common docker-latest docker-latest-logrotate \
  3. docker-logrotate docker-engine

更新 yum

  1. # 升级所有的包，同时也升级软件和系统内核
  2. sudo yum -y update

安装 Docker

安装需要的软件包和设置 yum 源

  1. sudo yum install -y yum-utils device-mapper-persistent-data lvm2
  2. # 设置yum源
  3. sudo yum-config-manager  --add-repo  https://download.docker.com/linux/centos/docker-ce.repo

yum 查看可用版本

  1. sudo yum list docker-ce --showduplicates | sort -r

yum 安装 Docker

这里需要选择docker-ce相关版本的docker安装

  1. sudo yum -y install docker-ce-18.06.3.ce

检查安装版本

执行如下命令：

  1. sudo docker version

结果如下

  1. Client:
  2.  Version:           18.06.3-ce
  3.  API version:       1.38
  4.  Go version:        go1.10.3
  5.  Git commit:        d7080c1
  6.  Built:             Wed Feb 20 02:26:51 2019
  7.  OS/Arch:           linux/amd64

设置开机自启动并启动 Docker

  1. sudo systemctl enable docker && systemctl start docker

设置镜像源

如果嫌原镜像源速度太慢，可以换成国内各大厂或机构的镜像源。

  1. # 1.创建Docker配置文件夹
  2. sudo mkdir -p /etc/docker
  3. # 2.创建配置：daemon.json
  4. sudo tee /etc/docker/daemon.json <<-'EOF'
  5. {
  6.   "registry-mirrors": ["https://6m7no14o.mirror.aliyuncs.com"],
  7.   "exec-opts": ["native.cgroupdriver=systemd"],
  8.   "log-driver": "json-file",
  9.   "log-opts": {
  10.     "max-size": "100m"
  11.   },
  12.   "storage-driver": "overlay2",
  13.   "storage-opts": [
  14.     "overlay2.override_kernel_check=true"
  15.   ]
  16. }
  17. EOF
  18. # 3.重启Docker
  19. sudo systemctl daemon-reload && systemctl restart docker
