通过一条命令安装：curl https://releases.rancher.com/install-docker/19.03.sh | sh

**查看docker版本信息：**

**`yum list docker-ce --showduplicates | ``sort` `-r`**

**`安装指定版本:`**

**`例如：`**

**`sudo yum install docker-ce-17.03.2.ce`**

**阿里云安装报错时：**

**解决办法：**

\#要先安装docker-ce-selinux-17.03.2.ce，否则安装docker-ce会报错

yum install https://download.docker.com/linux/centos/7/x86\_64/stable/Packages/docker-ce-selinux-17.03.2.ce-1.el7.centos.noarch.rpm

**参考文档：**

docker 安装：[https://docs.docker.com/engine/installation/linux/centos/][https_docs.docker.com_engine_installation_linux_centos]

**1、卸载旧版本**

$ sudo yum remove docker \\

docker-common \\

docker-selinux \\

docker-engine

![70][]

**2、安装依赖**

$ sudo yum install -y yum-utils \\

device-mapper-persistent-data \\

lvm2

![70 1][]

**3、设置docker源**

$sudo yum-config-manager \\

\--add-repo\\

[https://download.docker.com/linux/centos/docker-ce.repo][https_download.docker.com_linux_centos_docker-ce.repo]

**4、启动edge版 docker.repo源**

$sudo yum-config-manager --enable docker-ce-edge

如果需要关闭，执行一下

$sudo yum-config-manager --disable docker-ce-edge

**5、安装docker-ce版**

$sudo yum install docker-ce

![70 2][]

**6、启动docker**

$sudo systemctl start docker

**7、验证：执行hello-world**

dockerrun hello-world

**8、设置自动启动**

systemctlenable docker

如果需要禁止自动启动，则执行以下命令

systemctldisable docker

--------------------

**卸载docker**

$sudo yum remove docker-ce

**删除镜像、容器和自定义配置等**

$sudo rm -rf /var/lib/docker

**恢复网关路由：**

\[root@jy2docker02 docker\]\# ip route show|column -t  
169.254.0.0/16    dev  eth0             scope  link    metric  1002  
172.18.0.0/16     dev  br-33a4e6c9c7e8  proto  kernel  scope   link  src  172.18.0.1  
172.18.101.0/24   dev  eth0             proto  kernel  scope   link  src  172.18.101.96  
192.168.122.0/24  dev  virbr0           proto  kernel  scope   link  src  192.168.122.1  
\[root@jy2docker02 docker\]\# ip route del 172.18.0.0/16

镜像加速配置：

sudo mkdir -p /etc/docker  
sudo tee /etc/docker/daemon.json <<-'EOF'  
\{  
  "registry-mirrors": \["https://088aunhx.mirror.aliyuncs.com"\]  
\}  
EOF  
sudo systemctl daemon-reload  
sudo systemctl restart docker
