cannot restore segment prot after reloc:Permission denied解决
在 apache加载其他.so 的时候
环境：Linux localhost.localdomain 2.6.18-92.el5PAE
apache2+php4整合完毕后启动apache 时报错
root@localhost fgn]# /usr/local/apache/bin/apachectl restart
httpd: Syntax error on line 53 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/apache/modules/libphp4.so into server: /usr/local/apache/modules/libphp4.so: cannot restore segment prot after reloc: Permission denied

临时改变：
这是因为SELINUX的问题，需要关闭SELINX，执行：/usr/sbin/setenforce 0
永久改变：
编辑/etc/selinux/config，找到这段：
# 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
把 SELINUX=enforcing 注释掉：#SELINUX=enforcing ，然后新加一行为：
SELINUX=disabled
保存，关闭。
# 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
把 SELINUX=enforcing 注释掉：#SELINUX=enforcing ，然后新加一行为：
SELINUX=disabled
保存，关闭。
编辑/etc/sysconfig/selinux，找到:
# 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
如果SELINUX已经是 SELINUX=disabled，那么就不用改了，否则就把SELINUX=enforcing 注释掉，新加一行：
SELINUX=disabled
保存，退出。

SELINUX=disabled
保存，退出。
如果以上都不行：

在你保证SElinux 被disable后.还执行下
chcon -t texrel_shlib_t
如: chcon -t texrel_shlib_t /路径/路径/名字.so (这个文件视具体执行文件.)
以上两步.已经解决了很多server的问题了.
