Centos 7 安装卸载docker

安装docker

yum install docker

启动 Docker 服务,并将其设置为开机启动

service docker start chkconfig docker on

或者是以下操作

systemctl start docker.service systemctl enable docker.service

验证docker

docker run hello-world

会出现以下内容

Unable to find image 'hello-world:latest' locally Trying to pull repository docker.io/library/hello-world ... latest: Pulling from docker.io/library/hello-world 9db2ca6ccae0: Pull complete Digest: sha256:4b8ff392a12ed9ea17784bd3c9a8b1fa3299cac44aca35a85c90c5e3c7afacdc Status: Downloaded newer image for docker.io/hello-world:latest Hello 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 the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker ID: https://hub.docker.com/ For more examples and ideas, visit: https://docs.docker.com/engine/userguide/

卸载docker

查看docker安装包

yum list installed|grep docker

或者使用该命令

rpm -qa|grep docker

docker.x86_64 2:1.12.6-16.el7.centos @extras docker-client.x86_64 2:1.12.6-16.el7.centos @extras docker-common.x86_64 2:1.12.6-16.el7.centos @extra

分别删除安装包

yum –y remove docker.x86_64 yum –y remove docker-client.x86_64 yum –y remove docker-common.x86_64

删除docker 镜像

rm -rf /var/lib/docker

再次check docker是否已经卸载成功

rm -rf /var/lib/docker

如果没有搜索到，那么表示已经卸载成功。
