Add "Email Server" (multiserver config) with data on master server.

Hello, about a month ago I installed an ispconfig 3 server and configured a website with the addition of php 5.3.
At the time you will prepare the server as if it were a webserver, mailserver and dbserver.
Now I need to add a separate mail server and manage everything as if it were a multiserver.
I tried to follow the official howtoforge guide for the multiserver
(https://www.howtoforge.com/multiser...ueeze-with-ispconfig-3#multiserver-setup-with -dedicated-web-email-dns-amp-mysql-database-servers-on-debian-squeeze-with-ispconfig-)
but when I get to the part of the ispconfig script (launched on the mail server) where it tries to insert the records in the master I get this error:

MySQL master server database name [dbispconfig]:

ERROR: Stopped: Database already contains some tables.

I deleted all the records (related to mailserver) present in the server table of the master database.
What else should I do.
I would not want to reconfigure the existing website because it is managed by another person (webdesigner) and moreover it is a legacy site (php 5.3).
Thanks for your help.

 

We have two Virtual machine

1. webserver (master db ispconfig actually configured ) 192.168.1.1
2. mailserver (i will this slave of master , actually run script install ispconfig on this in expertmode and multiserver slave) 192.168.1.2

Ho guardato il codice di install.php, il problema arriva da install.php =>
./lib/installer_base.lib.php: $this->error('Stopped: Database already contains some tables.');
./lib/mysql.lib.php (line 650) =>
// gibt Array mit Tabellennamen
public function getTables($database_name = '') {
if(!is_object($this->_iConnId)) return false;
if($database_name == '') $database_name = $this->dbName;
$tb_names = $this->queryAllArray("SHOW TABLES FROM ??", $database_name);
return $tb_names;
}

I could blow this check, but I don't know the implications.
However, it should be noted that on the master I only have one site and one web configured, no mail account.

 

Looking at the code I solved it.
From a previous installation I had created a dbispconfig database on the local mailserver (maybe I made a mistake on a previous installation) I dropped the dbispconfig created locally on the mailserver and now everything works.
Thanks anyway, have a nice day.
