Cannot to database failed

[hexman123]

Hi.

Im trying to set up zabbix and when thorugh the whole process following this guide for debian 8. There about two small typos that I saw while installing and fixed so I dont think they are the cause.

http://www.tecmint.com/install-and-configure-zabbix-monitoring-on-debian-centos-rhel/

I got all the way until the very end, but thats where my problem is. When I enter the zabbix page, I get that the zabbix server is not running.

Zabbix server is running	No	localhost:10051

I used google that lead me to alot of zabbix post to try and fix this error. The closest I got was to see what was causing the error by viewing the zabbix_server.log. This is what I see

It just keeps on repeating the last line. It says somethign about the socket so I dont think its a password error, and I have checked both zabbix_server.conf and zabbix.conf.php so they match.

This is my zabbix.conf.php (my password IS "your_password" lol)

?php
// Zabbix GUI configuration file.
global $DB;

$DB['TYPE']     = 'MYSQL';
$DB['SERVER']   = 'localhost';
$DB['PORT']     = '0';
$DB['DATABASE'] = 'zabbix';
$DB['USER']     = 'zabbix';
$DB['PASSWORD'] = 'your_password';

// Schema name. Used for IBM DB2 and PostgreSQL.
$DB['SCHEMA'] = '';

$ZBX_SERVER      = 'localhost';
$ZBX_SERVER_PORT = '10051';
$ZBX_SERVER_NAME = 'zabbix';

$IMAGE_FORMAT_DEFAULT = IMAGE_FORMAT_PNG;
?> 

Few of my zabbix_server.conf

### Option: DBSocket
#       Path to MySQL socket.
#
# Mandatory: no
# Default:
# DBSocket=/var/run/mysqld/mysqld.sock

### Option: DBPort
#       Database port when not using local socket. Ignored for SQLite.
#
# Mandatory: no
# Range: 1024-65535
# Default (for MySQL):
# DBPort=3306

The onyl thing I have not tried is the SELinux topic that i have read. Could that help me out or is it unrelated. Need more info?

PS: I saw a post about sockets but i have to go, ill see if i can find it. It was posted here is zabbix forums

Have you verified that your path to the mysqld.sock file is correct?

Furthermore, are the configurations within that file set correctly?

Do you mind to UN-comment line

# DBSocket=/var/run/mysqld/mysqld.sock

and restart zabbix_server again?

[hexman123]

Well, I tried alot of things from reading the forums and different web places. I am learning more as I try new methods to fix the problem. I have tried both suggestions from above and un-commented other possibilities in the zabbix_server.conf . I will keep on trying to fix this and any suggestion would help.

Question.
Some people have said that SElinux might be causing the problems. As mentioned I am running Debian 8 and read this bit from the Debian website concerning SElinux

"CAUTION Reference policy not in jessie

Unfortunately the maintainers of the refpolicy source package did not handle release critical bugs on their package and the package got removed from jessie. This means that the selinux-policy-* packages are currently not installable in jessie and need to be fetched from another place. Hopefully they will come back in one of the point releases or in jessie-backports. In the meantime, you can grab them from unstable.
This sad situation at least proves that SELinux is not very popular in the set of users/developers who are running the development versions of Debian. Thus, if you opt to use SELinux, you should expect the default policy to not work perfectly and you will have to invest quite some time to make it suitable to your specific needs."

I am super new so I don't fully understand. Is it that SElinux IS installed but there is no way to change the the rules, or that SElinux is not working at all?
