- yum安装
依次执行以下命令,如有疑问请参考官方安装手册
[root@paascloud-test-001 ~]# yum remove docker docker-common docker-selinux docker-engine
[root@paascloud-test-001 ~]# yum install -y yum-utils device-mapper-persistent-data lvm2
[root@paascloud-test-001 ~]# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

以上方案安装慢的让你想哭 从官方安装包中安装, 我这里安装版本docker-ce-17.06.0.ce-1.el7.centos.x86_64.rpm
[root@paascloud-test-001 ~]# yum install /usr/local/src/tool/docker-ce-17.06.0.ce-1.el7.centos.x86_64.rpm -y
