Centos 7 安装指定版本的docker(19.03.9)
<p>1、安装之前前移除现有docker</p><pre><code>sudo yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-selinux \
docker-engine-selinux \
docker-engine
</code></pre>
<p>或者</p>
<pre><code>sudo yum remove docker-ce
</code></pre>
<p>2、安装工具</p>
<pre><code>sudo yum install -y yum-utils device-mapper-persistent-data lvm2
</code></pre>
<p>3、设置阿里镜像，访问速度更快一些</p>
<pre><code>sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
</code></pre>
<p>4、更新yum缓存</p>
<pre><code>sudo yum makecache fast
</code></pre>
<p>5、查看可用的社区版，一般选最新的就行</p>
<pre><code>yum list docker-ce --showduplicates | sort -r
</code></pre>
