一、Docker的安装

1.下载docker与依赖组件

# 下载依赖组件
yum -y install yum-utils device-mapper-persistent-data lvm2

# 导入docker官方仓库
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

# 下载docker
yum -y install docker-ce

# 启动并设置开机自启
systemctl start docker
systemctl enable docker

# 验证安装
[root@localhost-~]# docker version

2.配置Docker镜像

• 国内访问docker官方仓库经常受网络影响无法拉取镜像，所以将docker配置文件中地址该为国内地址

# 修改配置文件
vim /etc/docker/daemon.json

-----------------------------------------------------------------------------------------------------------
{
  "registry-mirrors": [
    "https://mj13bvr2.mirror.aliyuncs.com",
    "https://mirror.baidubce.com",
    "https://docker.m.daocloud.io",
    "https://docker.credclouds.com",
    "https://k8s.credclouds.com",
    "https://quay.credclouds.com",
    "https://gcr.credclouds.com",
    "https://k8s-gcr.credclouds.com",
    "https://ghcr.credclouds.com",
    "https://do.nark.eu.org",
    "https://docker.nju.edu.cn",
    "https://docker.mirrors.sjtug.sjtu.edu.cn",
    "https://docker.1panel.live",
    "https://docker.rainbond.cc"
  ],
  "data-root": "/etc/docker"
}
-----------------------------------------------------------------------------------------------------------

# 重载配置并重启docker
systemctl daemon-reload
systemctl restart docker

二、Docker-compose的安装

# 从GitHub镜像站下载docker-compose
wget https://bgithub.xyz/docker/compose/releases/download/v5.0.2/docker-compose-linux-x86_64
# 添加可执行权
chmod +x docker-compose-linux-x86_64

# 移动到系统环境变量并简单重命名
mv docker-compose-linux-x86_64 /usr/bin/docker-compose

# 验证安装
[root@localhost-~]# docker-compose version
Docker Compose version v2.29.0
