通过whereis查找phpMyAdmin安装目录

[root@localhost ～]# whereis phpMyAdmin

phpMyAdmin: /etc/phpMyAdmin /usr/share/phpMyAdmin

在这两个目录中找到config.inc.php文件，发现在/etc/phpMyAdmin目录中

在开发中有3台数据库服务器需要访问和管理，用客户端切换太过麻烦，直接用phpmyadmin来解决问题

修改根目录/etc/phpMyAdmin中的config.inc.php配置

$i = 0;

/*

 * 服务器A

 */

$i++;

/* Authentication type */

$cfg['Servers'][$i]['auth_type'] = 'config';

$cfg['Servers'][$i]['host'] = '127.0.0.1';

$cfg['Servers'][$i]['port'] = '3307';

$cfg['Servers'][$i]['connect_type'] = 'tcp';

$cfg['Servers'][$i]['compress'] = false;

保存，打开phpmyadmin,在首页就可以看到服务器列表了
