Rocky9.2安装docker-docker-compose

1.更换阿里云源（不换下载很慢）

sed -e 's|^mirrorlist=|#mirrorlist=|g' -e 's|^#baseurl=|baseurl=|g' -i.bak     /etc/yum.repos.d/rocky-*.repo
 dnf makecache

2.更新系统包

sudo dnf update -y
sudo dnf install -y yum-utils
sudo yum-config-manager --add-repo
sudo dnf install -y docker-ce docker-ce-cli containerd.io

3.启动 Docker 服务

sudo systemctl start docker # 启动
sudo systemctl restart docker #重启
sudo systemctl status docker #查看是否运行

4.安装 Docker Compose

curl -L "(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose**
sudo chmod +x /usr/local/bin/docker-compose
