phpMyAdmin允许定义输入的MySQL服务器IP地址，用户名和密码

修改/libraries/config.default.php为真即可，简单安全省事

$cfg['AllowArbitraryServer'] = true;

phpMyAdmin修改config.inc.php，服务器地址为下拉列表可选登录多个服务器

增加config.sample.inc.php文件，参考下面配置或者访问setup手动生成

/*
 * Generated configuration file
 * Generated by: phpMyAdmin 4.4.11 setup script
 * Date: Fri, 10 Jul 2015 15:54:42 +0800
 */

/* Servers configuration */
$i = 0;

/* Server: 10.4.14.64 [1] */
$i++;
$cfg['Servers'][$i]['verbose'] = '10.10.6.64';
$cfg['Servers'][$i]['host'] = '10.10.6.64';
$cfg['Servers'][$i]['port'] = '';
$cfg['Servers'][$i]['socket'] = '';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';

/* Server: 10.10.1.172 [2] */
$i++;
$cfg['Servers'][$i]['verbose'] = '10.10.1.172';
$cfg['Servers'][$i]['host'] = '10.10.1.172';
$cfg['Servers'][$i]['port'] = '';
$cfg['Servers'][$i]['socket'] = '';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';

/* End of servers configuration */

$cfg['blowfish_secret'] = '559f78c86f22d8.48481095';
$cfg['DefaultLang'] = 'zh_CN';
$cfg['ServerDefault'] = 1;
$cfg['UploadDir'] = '';
$cfg['SaveDir'] = '';
?>

如果mysql是5.1的这个版本php会报错（

您应升级到 MySQL 5.5.0 或更高版本

），解决方案：

vi /var/www/html/phpmyadmin/libraries/common.inc.php
#查找
if (PMA_MYSQL_INT_VERSION < 50500) {
#更换为
if (PMA_MYSQL_INT_VERSION < 50100) {
