Linux CentOS7.4 Docker环境搭建

Linux CentOS7.4 Docker环境搭建

一、安装Docker

1、卸载系统的旧版本

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

2、设置仓库、并修改为阿里云镜像

sudo yum install -y yum-utils \
  device-mapper-persistent-data \
  lvm2

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

3、安装Docker社区版（docker-ce）

sudo yum install -y docker-ce

4、启动Docker

systemctl start docker

5、备注：卸载Docker CE命令

yum remove docker-ce 
rm -rf /var/lib/docker

安装Docker Compose

1、运行以下命令来下载docker-compose最新版

sudo curl -L "https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

2、给二进制文件赋予权限

sudo chmod +x /usr/local/bin/docker-compose

3、测试安装

$ docker-compose --version
docker-compose version 1.22.0, build 1719ceb
