Heartbeat and ISpConfig 3 cluster

Hello everyone!

I have question about this tutorial (cluster creation):
http://www.howtoforge.com/installing...th-ispconfig-3

If master server goes down - the slave is get his functions after failture?
Or in this case we need to reconfigure the router to route ports to another IP?
If it is, can we use a heartbeat package with ISPConfig3?

Big thnks.

No, not automatically.

Hello!

Try to install cluster on virtual machines.

Replications is Ok.
I see on both server dbispconfig1 and dbispconfig2 DB.

But when I try to install ISPConfig3 on srv2 have the error:

Code:

Unable to read server configuration from database.root@srv2:/tmp/ispconfig3_install/install

How to solve it?

Thank you.

Which directories are mirrored by drbd and did you use different mysql users for the local ispconfig instances as described in the mirror guide?

Thank you for fast answer Till!

I use your perfect tutorial - cluster debian 6.0

For file replication I use Unison - (/var/vmail and /var/www)

on srv1 -
dbispconfig1 - user ispconfig
dbispconfig2 - user ispconfig2

on srv2 -
dbispconfig1 - user ispconfig
dbispconfig2 - user ispconfig2

Are you are sure that you executed the install.php script and not the update.php script on srv2? The error message that you posted exists in the updater only, not the installersoit can not appear during installation.

I cofigured heartbeat wotk great.
If need configuration steps I can post it.

When I stop the master server. Slave goes on.

After that I power on it (slave).

Create new Client on srv1, but there are no replication now.
on srv2 I did not see new client.

in show slave status:

Code:

Error 'Table 'attempts_login' already exists' on query. Default database: 'dbispconfig2'. Query: 'CREATE TABLE `attempts_login` (

 `ip` varchar(39) NOT NULL,

 `times` int(11) DEFAULT NULL,

 `login_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP

) ENGINE=MyISAM DEFAULT CHARSET=utf8'

How to solve it?

All times are GMT +2. The time now is 22:11.
