记录在CentOS 7下使用yum方式安装Docker环境的步骤。
1、移除旧版本:
yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-selinux \
docker-engine-selinux \
docker-engine
rm -rf /etc/systemd/system/docker.service.d
rm -rf /var/lib/docker
rm -rf /var/run/docker
rm -rf /usr/local/docker
rm -rf /etc/docker
2、安装一些必要的系统工具:
yum -y install yum-utils device-mapper-persistent-data lvm2
3、添加软件源信息:
yum-config-manager –add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
4、更新 yum 缓存:
yum makecache fast
5、安装 Docker-ce:
yum -y install docker-ce
6、启动 Docker 后台服务:
systemctl start docker
7、测试运行 hello-world:
docker run hello-world
8、安装centos,并以后台启动的方式运行centos:
docker run -itd centos /bin/bash
9、进入centos镜像:
[root@myserver ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
f57d4703adc3 centos “/bin/bash” About a minute ago Up About a minute jolly_dhawan
[root@myserver ~]# docker exec -it f57d4703adc3 /bin/bash
[root@f57d4703adc3 /]#
[root@f57d4703adc3 /]# cat /etc/RedHat-release
CentOS Linux release 7.6.1810 (Core)
[root@f57d4703adc3 /]#
至此,Docker环境搭建完成。
