I&#39;m setting up a new server and keep running into this problem.

When I try to log into the MySQL database with the root user, I get the error:

&gt; ERROR 1698 (28000): Access denied for user &#39;root&#39;@&#39;localhost&#39;

It doesn&#39;t matter if I connect through the terminal (SSH), through [phpMyAdmin][1] or a MySQL client, e.g., [Navicat][2]. They all fail.

I looked in the *mysql.user* table and get the following:

```lang-none
+------------------+-------------------+
| user             | host              |
+------------------+-------------------+
| root             | %                 |
| root             | 127.0.0.1         |
| amavisd          | localhost         |
| debian-sys-maint | localhost         |
| iredadmin        | localhost         |
| iredapd          | localhost         |
| mysql.sys        | localhost         |
| phpmyadmin       | localhost         |
| root             | localhost         |
| roundcube        | localhost         |
| vmail            | localhost         |
| vmailadmin       | localhost         |
| amavisd          | test4.folkmann.it |
| iredadmin        | test4.folkmann.it |
| iredapd          | test4.folkmann.it |
| roundcube        | test4.folkmann.it |
| vmail            | test4.folkmann.it |
| vmailadmin       | test4.folkmann.it |
+------------------+-------------------+
```

As you can see, user *root* should have access.

The Server is quite simple, as I have tried to troubleshoot this for a while now.

It&#39;s running [Ubuntu&amp;nbsp;16.04.1][3] LTS (Xenial Xerus) with Apache, MySQL and PHP, so that it can host websites, and iRedMail 0.9.5-1, so that it can host mail.

Log into the MySQL database works fine before I installed iRedMail. I also tried just installing iRedMail, but then root also doesn&#39;t work.

How can I fix my MySQL login problem or how can I install iRedMail over an existing MySQL install? And yes, I tried the [Installation Tips][4] and I can&#39;t find those variables in the configuration files.
