Observium is an open-source network monitoring platform designed for Linux and Unix-based systems. With Observium, you can monitor the availability, performance, and health of your network and its devices, including servers, routers, switches, and more. In this tutorial, we will guide you on how to install Observium on Fedora Server Latest.
Before you start installing Observium, make sure that you have the following prerequisites:
The first thing you should do is to update your Fedora Server's packages to ensure that you have the latest software versions before you install Observium. To do that, run the following commands:
sudo dnf update
sudo reboot
After the system reboots, log in again as the root user.
Next, install some packages that Observium depends on. Run the following command to install them:
sudo dnf install httpd mariadb-server mariadb php php-mysqlnd php-gd php-posix php-ldap php-mbstring php-snmp php-process subversion fping cronie net-snmp net-snmp-utils nmap-ncat git
Observium requires a database to store its data, so you need to configure the MariaDB database. Here are the steps:
Run the following command to start the MariaDB service:
sudo systemctl start mariadb
Secure the MariaDB installation by running this command:
sudo mysql_secure_installation
Follow the prompts to change the MariaDB root password and secure the installation.
Create a new database named "observium" and a new user named "observiumuser" by running these commands:
sudo mysql -uroot -p
MariaDB [(none)]> CREATE DATABASE observium;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON observium.* TO 'observiumuser'@'localhost' IDENTIFIED BY 'observiumpass';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> exit;
Replace "observiumpass" with a strong password of your choice.
Now you are ready to install Observium. Follow these steps:
Download the latest Observium version from the official website using this command:
sudo svn checkout http://www.observium.org/svn/observium/trunk /opt/observium
The above command will install Observium under the directory "/opt/observium".
Change to the Observium directory by running this command:
cd /opt/observium
Then, run the Observium installer using this command:
sudo ./discovery.php -u
This command will detect the devices on your network and set up the Observium database.
Edit the Observium configuration file by running this command:
sudo nano config.php
Set the following parameters:
$config['db_extension'] = 'mysqli';
$config['db_host'] = 'localhost';
$config['db_user'] = 'observiumuser';
$config['db_pass'] = 'observiumpass';
$config['db_name'] = 'observium';
$config['base_url'] = "/observium";
Replace the database credentials with the ones you created earlier.
Save and exit the file.
Create a new file named "observium" in the /etc/cron.d directory by running this command:
sudo nano /etc/cron.d/observium
Add the following lines:
*/5 * * * * observium /opt/observium/discovery.php -h all >> /dev/null 2>&1
*/5 * * * * observium /opt/observium/discovery.php -h new >> /dev/null 2>&1
*/5 * * * * observium /opt/observium/poller-wrapper.py 8 >> /dev/null 2>&1
0,10,20,30,40,50 * * * * observium /opt/observium/alerts.php >> /dev/null 2>&1
Save and exit the file.
Finally, run these commands to fix the file permissions:
sudo chown -R apache:apache /opt/observium
sudo setfacl -d -m group:apache:rwx /opt/observium/rrd /opt/observium/logs
To access the Observium web interface, you need to configure Apache. Here are the steps:
Create a new file named "observium.conf" in the /etc/httpd/conf.d directory by running this command:
sudo nano /etc/httpd/conf.d/observium.conf
Add the following lines:
<VirtualHost *:80>
ServerAdmin webmaster@example.com
DocumentRoot /opt/observium/html/
ServerName your.example.com
<Directory "/opt/observium/html/">
AllowOverride All
Options FollowSymLinks MultiViews
Require all granted
</Directory>
ErrorLog /var/log/httpd/observium-error-log
CustomLog /var/log/httpd/observium-access-log combined
</VirtualHost>
Replace "your.example.com" with your FQDN.
Save and exit the file.
Restart the Apache service by running this command:
sudo systemctl restart httpd
Once you have completed the previous steps, open a web browser and navigate to http://your.example.com/observium to access the Observium web interface.
Login with the default username "admin" and password "admin". You should see the Observium dashboard.
Congratulations! You have successfully installed Observium on your Fedora Server Latest.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
