使用Docker官方yum源安装指定版本Docker的标准操作流程

[日期:2018-10-22] 来源:Linux社区  作者:MRIVANDU [字体: ]

1、卸载老版本的Docker,没有安装则不卸载。

yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-selinux \
                  docker-engine-selinux \
                  docker-engine

配置官方yum源,启用稳定版源配置。

此步骤中,需要注意的是:要启用哪个版本的源就将其下的enable值设置为1,其余设置为0。命令中的引号必须使用单引号。yum.repos.d目录下的文件必须以.repo结尾。

查看当前源的可用版本。

[root@ChatDevOps-01 ~]# yum list docker-ce --showduplicates|grep "^doc"|sort -r
docker-ce.x86_64            18.06.1.ce-3.el7                    docker-ce-stable
docker-ce.x86_64            18.06.0.ce-3.el7                    docker-ce-stable

docker-ce.x86_64            17.03.0.ce-1.el7.centos            docker-ce-stable

安装docker-ce-18.06.0.ce-3.el7。若要安装其他版本则按照以下格式进行安装:docker-ce-

[root@ChatDevOps-01 ~]# yum -y install docker-ce-18.06.0.ce-3.el7
[root@ChatDevOps-01 ~]# docker version

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

启动docker服务。

[root@ChatDevOps-01 ~]# systemctl status docker

将docker服务设置为开机启动。

[root@ChatDevOps-01 ~]# systemctl enable docker
