/usr/local/apache/bin/apachectl restart
httpd: Syntax error on line 55 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/apache/modules/libphp5.so into server: /usr/local/apache/modules/libphp5.so: cannot restore segment prot after reloc: Permission denied
解决办法：
先禁止掉SELinux
更改/etc/sysconfig/selinux 文件的内容为 SELINUX=disabled
再使用：chcon -t texrel_shlib_t /usr/local/apache/modules/libphp5.so
