首先要有一个虚拟机或者云服务器

安装docker

1.安装yum工具

yum install -y yum-utils \
           device-mapper-persistent-data \
           lvm2 --skip-broken

2.更新本地镜像源

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

sed -i 's/download.docker.com/mirrors.aliyun.com/docker-ce/g' /etc/yum.repos.d/docker-ce.repo

yum makecache fast

3.安装

yum install -y docker-ce

启动docker

# 关闭防火墙
systemctl stop firewalld
# 禁止开机启动防火墙
systemctl disable firewalld

然后启动

systemctl start docker  # 启动docker服务

systemctl stop docker  # 停止docker服务

systemctl restart docker  # 重启docker服务

通过docker -v查看是否启动

有显示出docker版本号即为安装成功

安装 DockerCompose

这里比较简单，只需复制三个命令即可。

# 安装
curl -L https://github.com/docker/compose/releases/download/1.23.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

# 修改权限
chmod +x /usr/local/bin/docker-compose

# 补全命令
curl -L https://raw.githubusercontent.com/docker/compose/1.29.1/contrib/completion/bash/docker-compose > /etc/bash_completion.d/docker-compose
