[root@localhost ~]# cat /etc/selinux/config # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=enforcing # SELINUXTYPE= can take one of these two values: # targeted - Targeted processes are protected, # mls - Multi Level Security protection. SELINUXTYPE=targeted2.修改該配置文件中將enforcing替換為disabled

3.reboot重啟一下系統，使生效。 四、准備就緒，安裝docker-io，摸摸哒。 [root@localhost ~]# yum install docker-io 已加載插件：fastestmirror, refresh-packagekit, security 設置安裝進程

Please upgrade your kernel to 3.10.0. 但是目前表示我可以正常使用。
