CentOS SELinux

执行java报错

Error: failed /usr/admin/software/jdk1.7.0/jre/lib/i386/client/libjvm.so, because /usr/admin/software/jdk1.7.0/jre/lib/i386/client/libjvm.so: cannot restore segment prot after reloc: Permission denied

缘由是SELINUX被开启了
SELinux(Security-Enhanced Linux) 是美国国家安全局（NSA）对于强制访问控制的实现，是 Linux® 上最杰出的新安全子系统。NSA是在Linux社区的帮助下开发了一种访问控制体系，在这种访问控制体系的限制下，进程只能访问那些在他的任务中所须要文件。

[root@localhost bin]# 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 - SELinux is fully disabled.
SELINUX=enforcing
# SELINUXTYPE= type of policy in use. Possible values are:
#             targeted - Only targeted network daemons are protected. #             strict - Full SELinux protection. SELINUXTYPE=targeted

将SELINUX=enforcing注释掉便可 临时关闭用命令：/usr/sbin/setenforce 0
