【機器背景說明】Linux-Centos7；已有低版本的Docker

【目標環境說明】

卸載已有Docker，用docker-26.0.2.tgz安裝包安裝

1.Docker包下載

下載地址：Index of linux/static/stable/x86_64/

2.卸載已有的Docker

卸載之前首先停掉服務

sudo systemctl stop docker
sudo systemctl disable docker

采用官方提供的卸載方法：

#采用apt-get
sudo apt-get update
sudo apt-get purge -y docker-ce docker-ce-cli containerd.io
#yum方式
sudo yum remove docker docker-common docker-selinux docker-engine

或者手動卸載

sudo rm -rf /var/lib/docker
sudo rm -rf /etc/dockersudo rm -rf /usr/local/bin/docker
sudo rm -rf /usr/local/bin/docker-compose
sudo rm -rf /usr/local/bin/docker-machine
sudo rm -rf /usr/bin/docker
sudo rm -rf /usr/bin/docker-composesudo rm /usr/local/bin/docker
sudo rm /usr/bin/dockersudo rm /etc/systemd/system/docker.service
sudo rm /etc/systemd/system/docker.socket

如果存在NVIDIA的依賴卸載不掉的問題，則可去下面文件夾刪掉帶有"NVIDIA"的相關依賴文件

cat /etc/apt/sources.list.d/*

3.安裝Docker

解壓復制docker文件到系統環境變量中

sudo tar -xvzf docker-26.0.2.tar.gz
sudo cp ./docker/* /usr/bin/

配置docker的 systemd 服務?

sudo mkdir -p /etc/systemd/system/docker.service

?在內容中填上

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network.target[Service]
ExecStart=/usr/bin/dockerd
ExecReload=/bin/kill -s HUP $MAINPID
LimitNOFILE=1048576
LimitNPROC=infinity
TimeoutStartSec=0
Restart=always[Install]
WantedBy=multi-user.target

4.啟動并檢查Docker是否完成

sudo systemctl daemon-reload
sudo systemctl start docker
sudo systemctl enable dockerdocker --version
docker info

5.(選做) 安裝Docker-compose

下載地址：https://github.com/docker/compose/releases/tag/v2.33.0

下載完后直接扔到/usr//bin/里

并給權限

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