如果没报啥错误, 并且 docker images 也能看到一个列表目录而不是报错, 那表示你一定是成功了
如果报错：
# 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
解决办法：
# yum install device-mapper-event-libs
# docker version 查看docker的版本号，包括客户端、服务端、依赖的Go等
