Linux环境安装、卸载Docker
<p><span style="font-family: 楷体; font-size: 16px">安装：</span></p><p><span style="font-family: 楷体; font-size: 16px"> 1、Docker要求CentOS系统的内核版本高于 3.10 ，通过 <strong>uname -r </strong>命令查看你当前的内核版本是否支持安账docker</span></p>
<p><span style="font-family: 楷体; font-size: 16px"> 2、更新yum包：sudo yum update</span></p>
<p><span style="font-family: 楷体; font-size: 16px"> 3、安装需要的软件包，yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖的</span></p>
<p><span style="font-family: 楷体; font-size: 16px"> sudo yum install -y yum-utils device-mapper-persistent-data lvm2</span></p>
<p><span style="font-family: 楷体; font-size: 16px"> 4、设置yum源：sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo</span></p>
<p><span style="font-family: 楷体; font-size: 16px"> <img src="https://img2018.cnblogs.com/blog/1068501/201811/1068501-20181128145022180-347869770.png"></span></p>
<p><span style="font-family: 楷体; font-size: 16px"> 5、可以查看所有仓库中所有docker版本，并选择特定版本安装：yum list docker-ce --showduplicates | sort -r</span></p>
<p><span style="font-family: 楷体; font-size: 16px"> <img src="https://img2018.cnblogs.com/blog/1068501/201811/1068501-20181128145202512-1932354955.png"></span></p>
<p><span style="font-size: 16px"> 6、安装docker：sudo yum install docker-ce-17.12.0.ce</span></p>
<p><span style="font-size: 16px"> 7、启动、设置开启开机启动</span></p>
<p><span style="font-size: 16px"> sudo systemctl start docker</span></p>
<p><span style="font-size: 16px"> sudo systemctl enable docker</span></p>
<p><span style="font-size: 16px"> 8、验证安装是否成功(有client和service两部分表示docker安装启动都成功了)：docker version</span></p>
<p><span style="font-size: 16px"> <img src="https://img2018.cnblogs.com/blog/1068501/201811/1068501-20181128145435943-1657031411.png"></span></p>
<p><span style="font-size: 16px"> 9、查看docker启动状态：systemctl status docker（如下图即启动成功） </span></p>
<p><span style="font-size: 16px"><img src="https://img2018.cnblogs.com/blog/1068501/201811/1068501-20181128145740523-1861877184.png"><em id="__mceDel"><span style="font-family: 楷体"><br></span></em></span></p>
<p><span style="font-family: 楷体; font-size: 16px">卸载：</span></p>
<p><span style="font-family: 楷体; font-size: 16px"> 1、查询docker安装过的包：</span></p>
<p><span style="font-family: 楷体; font-size: 16px"> yum list installed | grep docker</span></p>
<p><span style="font-family: 楷体; font-size: 16px"> <img src="https://img2018.cnblogs.com/blog/1068501/201811/1068501-20181128144322696-1037021590.png"></span></p>
<p><span style="font-family: 楷体; font-size: 16px"> 2、删除安装包：</span></p>
<p><span style="font-family: 楷体; font-size: 16px"> yum remove docker-ce.x86_64 ddocker-ce-cli.x86_64 -y</span></p>
<p><span style="font-family: 楷体; font-size: 16px"> 3、删除镜像/容器等</span></p>
<p><span style="font-family: 楷体; font-size: 16px"> rm -rf /var/lib/docker</span></p>
<p><span style="font-family: 楷体; font-size: 16px"> </span></p><br><br>
