是不是config.inc.php3没有设置好啊
$cfgServers[1]['host'] = 'localhost'; // MySQL hostname
$cfgServers[1]['port'] = ''; // MySQL port - leave blank for default port
$cfgServers[1]['user'] = 'root'; // MySQL user (only needed with basic auth)
$cfgServers[1]['password'] = ''; // MySQL password (only needed with basic auth)
$cfgServers[1]['host'] = 'localhost'; // MySQL hostname
$cfgServers[1]['port'] = ''; // MySQL port - leave blank for default port
$cfgServers[1]['user'] = 'root'; // MySQL user (only needed with basic auth)
$cfgServers[1]['password'] = ''; // MySQL password (only needed with basic auth)
2)你的phpmyadmin里的lib.inc.php3大概有问题了,重新上传一遍吧
