或
docker -d

INFO[0000] +job serveapi(unix:///var/run/docker.sock) 
INFO[0000] WARNING: You are running linux kernel version 2.6.32, which might be unstable running docker. Please upgrade your kernel to 3.1.0.
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

解决运行提示问题：
1）：升级kernel2.6.32到 3.1

   1. rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org

  2. rpm -Uvh http://www.elrepo.org/elrepo-release-6-6.el6.elrepo.noarch.rpm

  3. yum --enablerepo=elrepo-kernel -y install kernel-lt

  4. vi /etc/grub.conf  注释掉 2.6的版本

  5. reboot
 
  2）解决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
    安装缺少的包：
    yum upgrade device-mapper-libs
