    <p>I'm trying to set up a web application for the first time on Amazon ec2 and everything is working except for remote access of PHPMyAdmin from the webserver instance. I've set up two 'Basic 64-bit Amazon Linux AMI 2011.02.1 Beta' instances of which one is acting as the webserver and the other as the MySQL server. Apache is installed on the webserver together with php and mysql, and the MySQL only has mysql server installed.</p> <p>I have set these two servers up by following these instructions :<a href="http://www.alexkorn.com/blog/2011/03/getting-php-mysql-running-amazon-ec2/" rel="nofollow">here</a> and setup PHPmyAdmin following these: <a href="http://www.calebogden.com/wordpress-on-linux-in-the-amazon-cloud-with-mac/" rel="nofollow">here</a>. I have installed PHPmyAdmin on the webserver. Now the problem is that whatever I try I get a '1045 Cannot log in to the MySQL server' warning while trying to log in. However I do get access when executing normal php-scripts fom the webserver or when I login through mysql while being logged in into the webserver. </p> <p>I've granted the root user all privileges on the public IP, on the public DNS, on the ip written as 'ip-111-222-333-444', on '%.internal', the internal ip and even on '%', but it still doesn't work(see mysql.user tabel below). Also included below is the config file from PHPMyAdmin. </p> <p>I hope to hear what I'm doing wrong and how I can fix it. Am I using the wrong ip's for the GRANTS or for the mysql server, or is there something else? If more information is needed please let me know.</p> <p>| host | user | password<br> -----+------+-------------------------------------------+<br> localhost | root | PASSWORD |<br> ip-own-server-ip | root |<br> 127.0.0.1 | root |<br> localhost | |<br> ip-'own-server-ip' | |<br> ip-'public-dns-webserver'.compute.internal | root | PASSWORD |<br> % | root | PASSWORD|<br> 'PUBLIC IP' | root | PASSWORD |<br> ip-'PUBLIC IP' | root | PASSWORD<br> %.internal | root | PASSWORD<br> ip-'public-dns-MySQLserver'.compute.amazonaws.com | root |PASSWORD<br> | ip-'LOCAL IP-ADDRESS' | root | PASSWORD| </p> <p>PHPMyAdmin config.ing.php file </p> <pre><code>&lt;?php /* * Generated configuration file * Generated by: phpMyAdmin 3.4.0 setup script * Date: Sun, 22 May 2011 11:01:18 +0000 */ /* Servers configuration */ $i = 0; /* Server: HipHop [1] */ $i++; $cfg['Servers'][$i]['verbose'] = 'HipHop'; $cfg['Servers'][$i]['host'] = 'ec2ip-xxx-xxx-xxx-xxx.compute.amazonaws.com'; $cfg['Servers'][$i]['port'] = ''; $cfg['Servers'][$i]['socket'] = ''; $cfg['Servers'][$i]['connect_type'] = 'tcp'; $cfg['Servers'][$i]['extension'] = 'mysqli'; $cfg['Servers'][$i]['auth_type'] = 'cookie'; $cfg['Servers'][$i]['user'] = 'root'; $cfg['Servers'][$i]['password'] = ''; /* End of servers configuration */ $cfg['DefaultLang'] = 'en'; $cfg['ServerDefault'] = 1; $cfg['blowfish_secret'] = '4dd8eb378ebd13.46094950'; $cfg['UploadDir'] = ''; $cfg['SaveDir'] = ''; ?&gt; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
