Docker

1、换掉关键文件

 vim /etc/yum.repos.d/CentOS-Base.repo

  
▽
[base]
name=CentOS-$releasever - Base - Mirrors Aliyun
baseurl=http://mirrors.aliyun.com/centos/$releasever/os/$basearch/
gpgcheck=1
enabled=1
gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7

[updates]
name=CentOS-$releasever - Updates - Mirrors Aliyun
baseurl=http://mirrors.aliyun.com/centos/$releasever/updates/$basearch/
gpgcheck=1
enabled=1
gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7

[extras]
name=CentOS-$releasever - Extras - Mirrors Aliyun
baseurl=http://mirrors.aliyun.com/centos/$releasever/extras/$basearch/
gpgcheck=1
enabled=1
gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7

[centosplus]
name=CentOS-$releasever - Plus - Mirrors Aliyun
baseurl=http://mirrors.aliyun.com/centos/$releasever/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7
 

2、运行以下命令，安装Docker。

sudo yum -y install docker-ce

3、执行以下命令，检查Docker是否安装成功。

sudo docker -v

Docker-Compose

需要先安装好docker

1、关闭防火墙

sudo systemctl stop firewalld

2、 下载二进制文件

从 GitHub 下载最新版 Docker Compose 的二进制文件：

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

国内加速下载（解决 GitHub 访问慢的问题）：

# 使用 FastGit 镜像
sudo curl -L "https://hub.fgit.cf/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
 
# 或使用 ghproxy 代理
sudo curl -L "https://ghproxy.com/https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

3、赋予执行权限

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

4、（可选）创建符号链接

将二进制文件链接到 /usr/bin 目录，方便全局调用：

sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
 

5、验证安装

docker-compose --version
