问题1

使用yum install docker安装完后启动不了

[root@test ~]# service docker start

Redirecting to /bin/systemctl start docker.service

Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

解决1

vi /etc/sysconfig/docker

解决2

[root@apptest ~]# yum remove docker
[root@apptest ~]# yum remove docker-selinux

[root@test yum.repos.d]# vi /etc/yum.repos.d/docker.repo

[dockerrepo]
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/
enabled=1
gpgcheck=1
gpgkey=https://yum.dockerproject.org/gpg

[root@test yum.repos.d]# yum install docker-engine

问题2

Delta RPMs disabled because /usr/bin/applydeltarpm not installed.
或
No Presto metadata available for base.

解决

yum provides '*/applydeltarpm'
yum install deltarpm
