## 安裝 docker ``` yum update -y; yum install -y yum-utils device-mapper-persistent-data lvm2; yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo; yum install -y docker-ce; systemctl start docker; systemctl enable docker; docker version; ``` ## 安裝 docker-compose 1. 直接Linux 下載解壓到 /usr/local/bin/ 這種有時候下載的特別慢 ``` sudo curl -L "https://github.com/docker/compose/releases/download/v2.6.0/docker-compose-linux-x86_64" -o /usr/local/bin/docker-compose; sudo chmod +x /usr/local/bin/docker-compose; docker-compose version; ``` 2. 官網手動下載:[https://github.com/docker/compose/releases](https://links.jianshu.com/go?to=https%3A%2F%2Fgithub.com%2Fdocker%2Fcompose%2Freleases) 下載x86架構: docker-compose-linux-x86_64 ``` 上傳到一個目錄, 然后復制并重命名 cp docker-compose-linux-x86_64 /usr/local/bin/docker-compose sudo chmod +x /usr/local/bin/docker-compose; docker-compose version; ``` # 修改安裝容器位置***** 一定要改， 不然Linux的系統盤就那么小，很容易就滿了 docker info 默認位置 ``` Docker Root Dir: /var/lib/docker ``` ``` vi /etc/docker/daemon.json ``` ``` { "data-root": "/自己的路徑/docker" } ``` 保存退出后 systemctl restart docker 再 docker info 查看
