首先查看内核
[root@netpc.com.cn~]# uname -r
2.6.32-431.23.3.el6.x86_64
据说是要3.1以上的
试试看
安装docker-io
yum -y install docker-io
查看状态
[root@netpc.com.cn ~]# service docker status
docker is stopped
启动docker进程
[root@netpc.com.cn ~]# service docker start
Starting cgconfig service: [ OK ]
Starting docker:[ OK ]
搜索php镜像
[root@netpc.com.cn ~]# docker search php
Cannot connect to the Docker daemon. Is ‘docker -d’ running on this host?
根据提示执行
[root@netpc.com.cn ~]# docker -d

docker: relocation error: docker: symbol dm_task_get_info_with_deferred_remove, version Base not defined in file libdevmapper.so.1.02 with link time reference
忽略警告，再次查看状态，docker死了，可是pid还在。
[root@netpc.com.cn ~]# service docker status
docker dead but pid file exists
网上搜索要安装对应的包
[root@netpc.com.cn ~]# yum upgrade device-mapper-libs
再次查看状态，已经变了。
[root@netpc.com.cn ~]# service docker status
docker dead but subsys locked
原来是要重启下。
[root@netpc.com.cn ~]# service docker restart
Stopping docker: [FAILED]
Starting docker:[ OK ]
再次查看状态，已经运行中了。
[root@netpc.com.cn ~]# service docker status
docker (pid 29178) is running…
