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=http://dl.rockylinux.org/$contentdir|baseurl=https://mirrors.aliyun.com/rockylinux|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 https://download.docker.com/linux/centos/docker-ce.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 "https://github.com/docker/compose/releases/download/2.29.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose**
sudo chmod +x /usr/local/bin/docker-compose
