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
解决：
这是因为SELINUX的问题，需要关闭SELINX，执行：
/usr/sbin/setenforce 0
引用：
When packaging an application on RHEL or CentOS, you may receive the following error:
cannot restore segment prot after reloc: Permission denied
This is likely due the the SE Linux setting being set to "enforcing"
.
To Temporarily disable enforcement on a running system
To permanently disable enforcement during a system startup
change "enforcing" to "disabled" in ''/etc/selinux/config'' and reboot.
.
By default, CentOS 5 has the SE Linux feature set to "enforcing". We are looking into ways to removing these steps.
