在epel-repo有帶1.7的docker
yum -y install epel-release yum -y install docker-io #升級成1.9.1 參考 https://www.jianshu.com/p/31248c006c06 curl -sSL -O https://get.docker.com/builds/Linux/x86_64/docker-1.9.1 chmod +x docker-1.9.1 mv /usr/bin/docker /usr/bin/docker-1.7 cp ./docker-1.9.1 /usr/bin/docker
docker pull centos:6.9
有問題 先關掉service
service stop docker
#看起來是必須升級kernel
rpm –import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
rpm -Uvh http://www.elrepo.org/elrepo-release-6-8.el6.elrepo.noarch.rpm
yum –enablerepo=elrepo-kernel install kernel-lt -y
另外在CentOS 6.5實際測試，docker 1.7不能執行，主要原因是
relocation error: docker-1.7: symbol dm_task_get_info_with_deferred_remove, version Base not defined in file libdevmapper.so.1.02 with link time reference 需要將libdevmapper更新: yum upgrade device-mapper-libs
修改/etc/grub.conf 更改default
reboot
