无法链接mysql

[califord]

情况说明

test.php 内容如下

<?php
error_reporting(E_ALL);
ini_set('display_errors','On');
$mysqli=new mysqli();
$mysqli->connect('192.168.1.5','lamp1234','lamp1234','lamptest');
$sqlstr='select * from chuhu';
$result=$mysqli->query($sqlstr);
while($row=$result->fetch_object())
{$name=$row->chuhu_id;
echo $name;
}
?>

在windows下的phpstudy环境可以得到相关的数据里的数据，ip:192.168.1.200

但是同样的代码放到linux+apache+php+mysql环境,IP地址:192.168.1.5,就是说程序与mysql均在同一服务器下，同时3306端口是打开的。防火墙已关闭，同时利用mysqlfont工具在widnows平台链接linux下的mysql是可以的，正如同样的程序上windows下是可以执行的。
已把short_open_tag = Off改为short_open_tag = On

却提示报错，具体信息如下
[Mon Jul 11 04:38:37 2016] [error] [client 192.168.1.5] PHP Warning: mysqli::connect(): (HY000/2003): Can't connect to MySQL server on '192.168.1.5' (13) in /var/www/html/test.php on line 5

my.ini文件 配置如下：
[root@localhost etc]# cat my.cnf
[mysqld]
default-character-set = utf8
port = 3306
skip-locking
#bind-address = 192.168.1.5
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
#symbolic-links=0

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

也就是说同样的的代码在linux却不能执行

还有什么办法，请各位指点一下，谢谢

[一起混吧]

估计是linux 把 192.168.1.5 当成远程地址了，所以不可以。 用localhost就可以了，没什么可纠结的

PHP Warning: mysqli::connect(): (HY000/2003): Can't connect to MySQL server on '192.168.1.5' (13) in /var/www/html/test.php on line 5 他不是已经告诉你链接不到 192.168.1.5 了吗？ 为什么不用 localhost 呢？

[califord]

SElinux的原因，呵呵，终于是找到原因了~~~~感谢各位

[califord]

链接localhost到真可以了，但就是没明白为什么呀？ 有哪里配置不对？

[傲雪星枫]

连接不到192.168.1.5的3306端口，看看是否没有权限，或密码错误

[关山路遥]

mysql只是配置localhost才能访问了吧？
