Docker和docker-compose环境搭建

1、安装Docker

更换源仓库为国内阿里源以提升安装速度，安装docker

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

yum -y install docker-ce

2、加入开机启动

systemctl start docker
systemctl enable docker

3、查看是否安装成功

docker version

4、安装Docker-compose

安装python pip

1、首先检查linux有没有安装python-pip包，终端执行 pip -V
```
pip -V
```
2、没有python-pip包就执行命令
```
yum -y install epel-release
```
3、执行成功之后，再次执行yum -y install python-pip
```
yum -y install python-pip
```
4、对安装好的pip进行升级 pip install --upgrade pip
```
pip install --upgrade pip
```
(至此，pip安装好了，执行pip -V 再次检查pip环境。)
安装Docker-Compose

终端执行：pip install docker-compose

pip install docker-compose

若报错Cannot uninstall 'requests'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall执行：

pip install docker-compose --ignore-installed requests

检查docker-compose 安装

docker-compose -version

5、更换docker源

修改配置文件，仓库地址

vim /etc/docker/daemon.json

{
  "registry-mirrors":["https://registry.docker-cn.com"]
}

重启docker服务

systemctl restart docker.service

至此docker和docker-compose安装完成
