[root@localhost apache2]# ./bin/apachectl start
httpd: Syntax error on line 53 of /usr/local/apache2/conf/httpd.conf: Cannot load /usr/local/apache2/modules/libphp5.so into server:
安装完成apache后，启动报错：
/usr/local/apache2/modules/libphp5.so: cannot restore segment prot after reloc: Permission denied
解决办法：
1、永久关闭SELINUX的方法
vi /etc/selinux/config 将SELINUX=enforcing 改成SELINUX=disabled 需要重启
2、临时关闭selinux
setenforce 0
