2. 安装docker-compose

查看最新版 https://github.com/docker/compose/releases

运行此命令以下载Docker Compose的当前稳定版本

curl -L "https://github.com/docker/compose/releases/download/v2.10.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

• 要安装不同版本的Compose，请替换v2.10.2 为要使用的Compose版本
• 如果github下载失败，可以科学上网下载后上传到服务器，安装yum install lrzsz -y，然后rz上传文件，然后mv docker-compose-linux-x86_64 /usr/local/bin/docker-compose

对二进制文件应用可执行权限

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

测试

[root@localhost ~]# docker-compose --version
Docker Compose version v2.10.2
