[root@linux log]# getenforce
Enforcing
[root@linux log]# setenforce 0
[root@linux log]# cat /etc/sysconfig/selinux

# 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=targeted

出现这个需要将selinux disable掉

[root@linux log]# vi /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=disable
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted

这个需要重启才能生效，如果需要立即生效，需执行

[root@linux ~]# setenforce
usage: setenforce [ Enforcing | Permissive | 1 | 0 ]

[root@linux ~]# setenforce 0

[root@linux log]# /etc/init.d/oracleasm createdisk asm1 /dev/sdg1
