在RedHat Linux5 中安装JDK1.7时，当我解压jdk，并且配置好了环境变量，测试的时候，报以下错误。

[root@jingfeng01 ~]# java -versionError: dl failure on line 863Error: failed /usr/java/jdk1.7.0_60/jre/lib/i386/client/libjvm.so, because /usr/java/jdk1.7.0_60/jre/lib/i386/client/libjvm.so: cannot restore segment prot after reloc: Permission denied

在网上找了找错误，最后发现原来是SELinux的缘故,关闭SELinux即可解决

解决方案：

[root@jingfeng01 ~]# vi /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 - SELinux is fully disabled.SELINUX=disabled# 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 改为SELINUX=disabled 关闭，然后重启机器，让其生效
