How to Install Zabbix Server 3.0 on linux environment

Creating initial database

Create zabbix database and user on MySQL. For instructions on doing that,
[root@localhost ~]# systemctl start mariadb
[root@localhost ~]# systemctl enable mariadb
[root@localhost ~]# mysql_secure_installation
In order to log into MariaDB to secure it, we’ll need the current
password for the root user.  If you’ve just installed MariaDB, and
you haven’t set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on…
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] Y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
… Success!
Remove anonymous users? [Y/n] Y
… Success!
Disallow root login remotely? [Y/n] Y
… Success!
Remove test database and access to it? [Y/n] Y
– Dropping test database…
… Success!
– Removing privileges on test database…
… Success!
Reload privilege tables now? [Y/n] Y
… Success!

Cleaning up…
How to Install Zabbix Server 3.0 on linux environment
All done!  If you’ve completed all of the above steps, your MariaDB
installation should now be secure.
[root@localhost ~]# mysql_secure_installation
MariaDB [(none)]>

MariaDB [(none)]> create database zabbix_db;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> grant all privileges on zabbix_db.* to zabbix@localhost identified by ‘redhat’;
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> exit
[root@localhost ~]# cd /usr/share/doc/zabbix-server-mysql-3.0.2/
[root@localhost zabbix-server-mysql-3.0.2]# gunzip create.sql.gz
[root@localhost zabbix-server-mysql-3.0.2]# mysql -u root -p zabbix_db < create.
sql

Starting Zabbix server process


Edit database configuration in zabbix_server.conf
[root@localhost ~]# vi /etc/zabbix/zabbix_server.conf
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix

Editing PHP configuration for Zabbix frontend

Apache configuration file for Zabbix frontend is located in /etc/httpd/conf.d/zabbix.conf. Some PHP settings are already configured.
php_value max_execution_time 300
php_value memory_limit 128M
php_value post_max_size 16M
php_value upload_max_filesize 2M
php_value max_input_time 300
php_value always_populate_raw_post_data -1
# php_value date.timezone Asia/Dhaka

After changing the configuration file restart the apache web server.
Install Zabbix Server 3.0 on linux
[root@localhost ~]# systemctl start httpd

Finally Start Zabbix server process by
[root@localhost ~]#service zabbix-server start


Now you login your zabbix and install web content with Database.

How to Show My Computer Icon on Windows 2012, R2 Server

As mentioned earlier, this feature is not included by default. If you can manage the server without  My computer icon on desktop or other personalization options, better continue with it without installing additional features. But if you desperately want my computer icon then follow these steps.missing personalize option
We must install ‘Desktop Experience’ feature to get back personalization options which will help to get My computer back on Windows 2012 R2 server desktop.
Go to ‘Add Roles and Features’ in server dashboard, select ‘Role-based or Feature-based installation’ , do not select anything in Server Roles, and under Features select ‘Desktop Experience’ as mentioned below.
select desktop experience in features
Install other required features too.
You must restart the server after the installation.

Even though this feature would have added several options but our concern is to get My computer icon on desktop.
After the restart you must be seeing the ‘Personalize’ from right click menu from desktop (which was not shown in earlier screenshot).
Show My Computer Icon on Windows 2012
Click on Personalize and ‘Change desktop icons’ at top left corner. It will bring back our traditional desktop icons settings like Windows 7 or 8.
Select the icons you want to show, in our case it is My Computer icon.
Show My Computer Icon on Windows 2012
That will show My computer icon on Windows 2012 and R2 server desktop.
