centos安装docker和docker-compose

1. 安装docker

// 安装Docker的依赖
yum install -y yum-utils device-mapper-persistent-data lvm2

// 安装Docker-CE
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum install docker-ce

// 启动Docker后台服务
systemctl start docker

// 测试运行
docker run hello-world

// 设置开机启动
systemctl enable docker

2. 检查docker版本

   docker version

   输出为：

   Client: Docker Engine - Community
    Version:           28.1.1
    API version:       1.49
    Go version:        go1.23.8

    OS/Arch:           linux/amd64

3. 根据docker版本下载docker-compose
   选择版本 https://github.com/docker/compose/releases

4. 安装docker-compose

curl -L "https://github.com/docker/compose/releases/download/v2.36.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

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

# 验证安装
docker-compose --version
```bash

## 常用命令
1. 删除docker volume data
`docker volume rm $(docker volume ls -qf dangling=true)`

2. 启动
`docker-compose up -d`
3. 停止
`docker-compose down`
4. 查看日志
`docker-compose logs -f`
5. 查看容器状态
`docker ps -q -a`
6. 进入容器
`docker-compose exec -it web /bin/bash`
