New Zabbix install with Separate MariaDB database

dafyre

I have changed the zabbix config file to add the database in question.

You will also need to set the configuration in the Zabbix Web site config as well as the Zabbix Server config.

antonit

@dafyre Hmmm... maybe that's what I'm missing. Let me check.

antonit

@dafyre Yes, I had already added the database parameters to the file (zabbix.conf.php) and have also done it to the zabbix_server.conf file.

scottalanmiller

Looking at the server, zabbix-release was on version 2.4. Got that fixed.

dafyre

SSH in to your Zabbix server.

Are you able to mysql -u zabbixuser -p -h remotemariadb ?

antonit

@dafyre Nope. Access denied.

That's the first thing, shouldn't be looking at Zabbix at all until the database is ready.

scottalanmiller

Two quick notes on the zabbix.conf.php file (because I'm looking at the server).

One is that there was a typo and the file wasn't valid. I fixed that.

Second is that the host is not specified at all, so it isn't looking for the database server anywhere but locally.

scottalanmiller

Here is what the file looked like...

$DB['DATABASE'] = 'zabbix';
$DB['USER'] = zabbix';
$DB['PASSWORD'] = 'password'

Noting a missing quote, a missing semi-colon and a missing server name. Here is what it should look like...

$DB['DATABASE'] = 'zabbix';
$DB['USER'] = 'zabbix';
$DB['PASSWORD'] = 'password';
$DB['SERVER'] = 'maria';

antonit

Correction. I can login. Mistyped the password (where's that damn post it note...)

antonit

$DB['SERVER'] = 'maria';

Ahhh... Wasn't sure how to put that in. Sadly, I still cannot connect

scottalanmiller

What is the command to attempt to start the Zabbix service?

antonit

@scottalanmiller # service zabbix-server start

Here is the Zabbix log now...

 15247:20160218:170737.082 using configuration file: /etc/zabbix/zabbix_server.conf
 15247:20160218:170737.086 [Z3005] query failed: [1146] Table 'zabbix.users' doesn't exist [select userid from users limit 1]
 15247:20160218:170737.086 cannot use database "zabbix": database is not a Zabbix database

To me, it looks like the Zabbix SQL Script has not yet been run against the database server to set up the database.

scottalanmiller

Suspiciouns confirmed...

MariaDB [zabbix]> show tables;
Empty set (0.00 sec)

scottalanmiller

And there we go, just needed the database installed:

zcat /usr/share/doc/zabbix-server-mysql-3.0.0/create.sql.gz | mysql -uzabbix -hmaria -ppassword zabbix

Up and running.

scottalanmiller

Now here is the issue, very odd...

zabbix database issue

scottalanmiller

nothing goes to the logs when this fails, very frustrating.

scottalanmiller

Can't find any reason why it is not connecting to the database and there is zip in the logs. Not impressed with how it handles this situation.
