Docker

1、換掉關鍵文件

?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

2、運行以下命令，安裝Docker。

sudo yum -y install docker-ce

3、執行以下命令，檢查Docker是否安裝成功。

sudo docker -v

Docker-Compose

需要先安裝好docker

1、關閉防火墻

sudo systemctl stop firewalld

2、?下載二進制文件

從 GitHub 下載最新版 Docker Compose 的二進制文件：

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

國內加速下載（解決 GitHub 訪問慢的問題）：

# 使用 FastGit 鏡像
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、賦予執行權限

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

4、（可選）創建符號鏈接

將二進制文件鏈接到?/usr/bin?目錄，方便全局調用：

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

5、驗證安裝

docker-compose --version
?
