### 测试


执行完成后，直接在浏览器中输入服务器地址，即可进行测试  
 ![在这里插入图片描述](https://img-blog.csdnimg.cn/20200718134447847.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQyNTM0MDI2,size_16,color_FFFFFF,t_70)  
 输入服务器地址/mysql.php，对网站是否能连接到后端MySQL进行测试  
 ![在这里插入图片描述](https://img-blog.csdnimg.cn/20200718134920772.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQyNTM0MDI2,size_16,color_FFFFFF,t_70)


若连接MySQL出现报错现象，那有可能就是mysql.php文件有错误  
 ![在这里插入图片描述](https://img-blog.csdnimg.cn/20200718135034641.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQyNTM0MDI2,size_16,color_FFFFFF,t_70)  
 产生报错后，将以下内容直接复制到mysql.php，然后刷新即可

<?php $link=mysql_connect('127.0.0.1','lnmp','123456'); if ($link)echo "connection success......"; mysql_close(); ?>
