Installation of Zabbix in Centos 7

Lakshmana

When I done the service restart i got these output,whether any issues arises by these kind of outputs mentioned below

[lakshmana@dny-lnx-zabbix create]$ sudo nano /etc/httpd/conf.d/zabbix.conf
[lakshmana@dny-lnx-zabbix create]$ sudo systemctl start zabbix-server
[lakshmana@dny-lnx-zabbix create]$ sudo systemctl start zabbix-agent
[lakshmana@dny-lnx-zabbix create]$ sudo systemctl restart httpd
[lakshmana@dny-lnx-zabbix create]$ sudo systemctl restart mariadb
[lakshmana@dny-lnx-zabbix create]$ sudo systemctl enable zabbix-server
ln -s '/usr/lib/systemd/system/zabbix-server.service' '/etc/systemd/system/multi-user.target.wants/zabbix-server.service'
[lakshmana@dny-lnx-zabbix create]$ sudo systemctl enable zabbix-agent
ln -s '/usr/lib/systemd/system/zabbix-agent.service' '/etc/systemd/system/multi-user.target.wants/zabbix-agent.service'

It looks like he's using the right path now...

The error it is showing is that it can't create the tables... That seems like a MySQL error or something else. I'm not sure what to check next.

Lakshmana

The Zabbix Installation page came in the browser after configuring the other things also

dafyre

Can you check the Permissions of /var/lib/mysql ?

Make sure it is owned by mysql?

ls -ohrd /var/lib/mysql

Lakshmana

The output for the above command is
drwxr-xr-x 5 mysql 4.0K Sep 9 01:57 /var/lib/mysql/

Lakshmana

Then I have used this command as per teh Dafyre suggestion
ls -ohrd /var/lib/mysql/*

thereare many files are present in it

dafyre

Are they all owned by mysql or root or what?

Always provide the output, not just your summary of what you feel you see.

Turn off SELinux to be sure it is not blocking the creation of new database files.

ls -ohrd /var/lib/mysql/*

Looks healthy from a permissions standpoint.

Lakshmana

[lakshmana@dny-lnx-zabbix ~]$ sestatus -v

scottalanmiller

Okay, so SELinux is off.

dafyre

Curious... It looks like all the tables are there now.

What happens if you:

mysql -u root -p
use zabbixdb;
describe users;

?

The output is provided below

It looks like the data has loaded right... let's check one more...

Okay, so everything appears to be working.

What happens if you http://<ip of your server>/zabbix ?
