安装docker

yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager \
    --add-repo \
    https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum install docker-ce docker-ce-cli containerd.io -y
启动
systemctl daemon-reload
systemctl restart docker

安装docker-compose

wget https://github.com/docker/compose/releases/download/v2.10.2/docker-compose-linux-x86_64
mv docker-compose-linux-x86_64  /usr/local/bin/docker-compose
将可执行权限应用于二进制文件：
$ sudo chmod +x /usr/local/bin/docker-compose
创建软链：
$ sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
测试是否安装成功：
$ docker-compose --version
