总结下docker的一些知识
docker安装有网络版
参考文章我以前试过这个帖子建议安装高版本的docker20以上的不然可能会有一些问题
## 1、安装依赖
[rootiZo7e61fz42ik0Z ~]#yum install -y yum-utils device-mapper-persistent-data lvm2
## 2、添加docker软件源
[rootiZo7e61fz42ik0Z ~]#yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
## 3、只保留稳定版本
[rootiZo7e61fz42ik0Z ~]#yum-config-manager --disable docker-ce-edge
[rootiZo7e61fz42ik0Z ~]#yum-config-manager --disable docker-ce-test
## 4、更新包索引
[rootiZo7e61fz42ik0Z ~]#yum makecache fast
## 5、更新yum包索引
[rootiZo7e61fz42ik0Z ~]#yum list docker-ce --showduplicates|sort -r

提前下载docker下载docker的安装文件https://download.docker.com/linux/static/stable/x86_64/开始安装
docker 安装这里我下载的19.03.9后续就出现了一些端口安全的问题
# 解压docker 安装包
tar -zxvf docker-19.03.9.tgz
# 解压文件移动到到 /usr/bin
mv docker/* /usr/bin/
# 配置docker.service 文件
cd /etc/systemd/system/
# 把离线部署里的docker.service文件传到这个目录
可以使用sftp或者rz命令
# 赋予执行权限
chmod x /etc/systemd/system/docker.service
# 重新加载配置文件
systemctl daemon-reload
# 开机自启
systemctl enable docker.service
# 启动docker
systemctl start docker
