1.查找主机上关于Docker的软件包
rpm -qa | grep docker – – 列出包含docker字段的软件的信息

2.使用yum remove卸载软件

yum remove docker-client-1.13.1-161.git64e9980.el7_8.x86_64
yum remove python36-docker-pycreds-0.2.1-2.el7.noarch
yum remove docker-common-1.13.1-161.git64e9980.el7_8.x86_64
yum remove docker-1.13.1-161.git64e9980.el7_8.x86_64
yum remove python36-dockerpty-0.4.1-18.el7.noarch
yum remove python36-docker-2.6.1-3.el7.noarch

3.使用curl升级到最新版
 curl -fsSL https://get.docker.com/ | sh

4.重启Docker
systemctl restart docker

5.设置Docker开机自启
 systemctl enable docker

6.查看Docker版本信息
docker version

7.查看Docker系统信息，包括镜像和容器数…
docker info

8.docker-compose

# 后台启动容器
docker-compose up -d

docker-compose ps
# 停止容器

#查看docker-compose版本
docker-compose -v

 

 

注意：这个一定要设置目录

否则后面会踩坑（导致如下问题，也面登陆502）

./prepare 

 ./install.sh

✖ Need to install docker-compose(1.18.0+) by yourself first and run this script again.

 

Compose 安装
Linux
Linux 上我们可以从 Github 上下载它的二进制包来使用，最新发行的版本地址：https://github.com/docker/compose/releases。

运行以下命令以下载 Docker Compose 的当前稳定版本：

$ sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
要安装其他版本的 Compose，请替换 1.24.1。

将可执行权限应用于二进制文件：

$ sudo chmod +x /usr/local/bin/docker-compose
创建软链：

$ sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
测试是否安装成功：

$ docker-compose --version
cker-compose version 1.24.1, build 4667896b
注意： 对于 alpine，需要以下依赖包： py-pip，python-dev，libffi-dev，openssl-dev，gcc，libc-dev，和 make。
