Warning: mysqli::real_connect(): php_network_getaddresses: getaddrinfo failed

在安装iTOP的时候你可能会遇到如题所示的警告，具体如下：

解法：
在上面设置MySQL服务器地址的时候，将【localhost】，改成【127.0.0.1】

可以看到，已经没有警告了。

DataTables：从MySQL获取数据

前提：
DataTables的环境的搭建不在描述，前面的文档中都已经写了。

本文主要有以下部分：
1. PHP代码的编写：两个PHP文件
2. 数据库的数据表的准备：MySQL

先看看数据库的部分：

iTop：配置管理 – 联系人，在MySQL数据库中对应的表

在ITOP中，配置管理里面有个模块是联系人。
如下：

这部分的内容其实是存放在后端的数据库中的。

看看我们的数据库的配置：

[root@itop production]# pwd                 
/www/wwwroot/itop/conf/production
[root@itop production]# 
[root@itop production]# ls -ltr
total 12
-r--r--r-- 1 www www 9479 Feb 12 15:17 config-itop.php
[root@itop production]# 
[root@itop production]# cat config-itop.php | grep "db_"
        'db_host' => '192.168.174.128',
        'db_name' => 'itop_data',
        'db_pwd' => '你的数据库密码',
        'db_subname' => '',
        'db_user' => 'itop',
[root@itop production]#

[root@itop production]# pwd

/www/wwwroot/itop/conf/production

[root@itop production]#

[root@itop production]# ls -ltr

total 12

-r--r--r-- 1 www www 9479 Feb 12 15:17 config-itop.php

[root@itop production]#

[root@itop production]# cat config-itop.php | grep "db_"

'db_host' => '192.168.174.128',

'db_name' => 'itop_data',

'db_pwd' => '你的数据库密码',

'db_subname' => '',

'db_user' => 'itop',

[root@itop production]#

然后去数据库中查看：

PHP：PDO访问MySQL的时候，返回的json数据中文乱码

问题如题所示，具体如下：

解决该问题，需要在PDO请求数据库连接的时候，就把字符集的设定声明进去。

如下修改代码就能解决中文乱码问题：

<?php

//字符集编码
//header("content-Type: text/html; charset=utf-8");

//变量声明
$servername = "localhost";
$username = "adamhuan";
$password = "***********";

//字符集处理：json
function encode_json($str) {
  return urldecode(json_encode(url_encode($str)));
}

function url_encode($str) {
  if(is_array($str)) {
    foreach($str as $key=>$value) {
      $str[urlencode($key)] = url_encode($value);
    }
  } else {
    $str = urlencode($str);
  }

  return $str;
}

//MySQLi extention
//-------------------------------
// 创建连接
//面向对象
//$conn = new mysqli($servername, $username, $password);

//面向过程
//$conn = mysqli_connect($servername, $username, $password);

// 检测连接
//if ($conn->connect_error) {
//    die("连接失败: " . $conn->connect_error);
//}
//echo "连接成功";

//PDO
//----------------------------------------
try {
    $conn = new PDO("mysql:host=$servername;", $username, $password,array(PDO::MYSQL_ATTR_INIT_COMMAND => "set names utf8"));
    //echo "连接成功<br/>";
    //echo "===================<br/>";
    //echo "";
}
catch(PDOException $e)
{
    echo "连接失败<br/>";
    echo "===================<br/>";
    echo $e->getMessage();
    echo "<br/>";
    echo "";
}

//for DataTables Coding

//SQL语句
$sql = "select * from gds_its_customer_data.people";

//SQL语句执行
$do = $conn->prepare($sql);
$do->execute();

//SQL语句，获得结果集
$row = $do->fetchAll(PDO::FETCH_ASSOC);

//--> json encoding
//$row_json_encoding = json_encode($row,JSON_UNESCAPED_UNICODE);

//输出
//echo $row;

//echo _json($row);
//echo $row_json_encoding;

echo encode_json($row);

//关闭连接
//MYSQLI
//面向对象
//$conn->close();

//面向过程
//mysqli_close($conn);

//PDO
$conn = null;

?>

<?php

//字符集编码

//header("content-Type: text/html; charset=utf-8");

//变量声明

$servername = "localhost";

$username = "adamhuan";

foreach($str as $key=>$value) {

$str[urlencode($key)] = url_encode($value);

}

} else {

$str = urlencode($str);

}

return $str;

}

// die("连接失败: " . $conn->connect_error);

//}

//echo "连接成功";

//PDO

//----------------------------------------

try {

//echo "连接成功 ";

//echo "=================== ";

//echo "";

}

catch(PDOException $e)

{

echo "连接失败 ";

echo "=================== ";

echo $e->getMessage();

echo " ";

echo "";

}

//for DataTables Coding

//SQL语句

$sql = "select * from gds_its_customer_data.people";
