Apache结合php

httpd主配置文件/usr/local/apache2.4/conf/httpd.conf
vim /usr/local/apache2.4/conf/httpd.conf //修改以下4个地方
ServerName（前面#去掉）
Require all denied //改成Require all granted（防止打开虚拟主机配置文件时显示403）
AddType application/x-httpd-php .php //解析php
DirectoryIndex index.html index.php
/usr/local/apache2.4/bin/apachectl -t //测试语法
/usr/local/apache2/bin/apachectl graceful 重新加载配置文件,不会把进程杀掉
/usr/local/apache2.4/bin/apachectl start //启动服务
netstat -lntp
curl localhost
vim /usr/local/apache2.4/htodcs/test.php //增加如下内容
<?php
Phpinfo();
?>

问题！！

/usr/local/apache2.4/bin/apachectl restart
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
解决办法：
vi conf/httpd.conf
#ServerName www.example.com:80 //这个打开
