删除旧版本的Docker
sudo yum remove docker \docker-client \docker-client-latest \docker-common \docker-latest \docker-latest-logrotate \docker-logrotate \docker-engine这个可能是匹配不到的来个狠一点的
sudo yum remove docker*带有Docker的全部删掉
安装Docker仓库
sudo yum install -y yum-utils
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo安装Docker
安装最新版本
安装Docker最新版不带版本的默认最新版本 sudo yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin安装指定版本
查找docker-ce的版本
[rootWDQCVM ~]# yum list docker-ce --showduplicates | sort -r* updates: mirrors.aliyun.com
Loading mirror speeds from cached hostfile
Loaded plugins: fastestmirror* extras: mirrors.aliyun.com
docker-ce.x86_64 3:24.0.5-1.el7 docker-ce-stable
docker-ce.x86_64 3:24.0.4-1.el7 docker-ce-stable
docker-ce.x86_64 3:24.0.3-1.el7 docker-ce-stable
docker-ce.x86_64 3:24.0.2-1.el7 docker-ce-stable
docker-ce.x86_64 3:24.0.1-1.el7 docker-ce-stable查找docker-ce-cli的版本
[rootWDQCVM ~]# yum list docker-ce-cli --showduplicates | sort -r* updates: mirrors.aliyun.com
Loading mirror speeds from cached hostfile
Loaded plugins: fastestmirror
Installed Packages* extras: mirrors.aliyun.com
docker-ce-cli.x86_64 1:24.0.5-1.el7 docker-ce-stable
docker-ce-cli.x86_64 1:24.0.5-1.el7 docker-ce-stable
docker-ce-cli.x86_64 1:24.0.4-1.el7 docker-ce-stable
docker-ce-cli.x86_64 1:24.0.3-1.el7 docker-ce-stable
docker-ce-cli.x86_64 1:24.0.2-1.el7 docker-ce-stable
docker-ce-cli.x86_64 1:24.0.1-1.el7 docker-ce-stable 将参数替换即可
通用示例
sudo yum install docker-ce-VERSION_STRING docker-ce-cli-VERSION_STRING containerd.io docker-buildx-plugin docker-compose-plugin指定版本示例
sudo yum install docker-ce-24.0.4-1.el7 docker-ce-cli-24.0.4-1.el7 containerd.io docker-buildx-plugin docker-compose-pluginCentos7.9版本安装Docker指定版本时安装了好多次这么设置版本号才成功在软件包名称和版本号之间不需要添加数字和冒号但官网给出的实例是带有:的费解。
校验是否成功
[rootWDQCVM ~]# sudo systemctl start docker
[rootWDQCVM ~]# sudo docker --version
Docker version 24.0.4, build 3713ee1
[rootWDQCVM ~]# 有以下这些就可说明成功了
[rootWDQCVM ~]# sudo docker run hello-worldHello from Docker!
This message shows that your installation appears to be working correctly.To generate this message, Docker took the following steps:1. The Docker client contacted the Docker daemon.2. The Docker daemon pulled the hello-world image from the Docker Hub.(amd64)3. The Docker daemon created a new container from that image which runs theexecutable that produces the output you are currently reading.4. The Docker daemon streamed that output to the Docker client, which sent itto your terminal.To try something more ambitious, you can run an Ubuntu container with:$ docker run -it ubuntu bashShare images, automate workflows, and more with a free Docker ID:https://hub.docker.com/For more examples and ideas, visit:https://docs.docker.com/get-started/[rootWDQCVM ~]# Docker安装个NGINX
