Nagios is a powerful open-source monitoring system that allows you to keep an eye on your network, servers, and applications. In this tutorial, we will be walking through how to install Nagios on Void Linux.
First, we need to install the dependencies required for Nagios to run. Open a terminal and run the following command:
sudo xbps-install -S apache php php-fpm gd openssl gd-devel httpd-devel make gcc glibc-static
This command will install the packages needed to run Nagios.
Next, we need to download the Nagios source code from the official website. You can download it by running the following command:
wget https://github.com/NagiosEnterprises/nagioscore/archive/nagios-4.4.6.tar.gz
This command will download the Nagios source code to your current directory.
Once the download is complete, we need to extract the source code and compile it. Run the following commands:
tar xf nagios-4.4.6.tar.gz
cd nagioscore-nagios-4.4.6/
./configure --with-command-group=nagcmd
sudo make all
sudo make install
sudo make install-commandmode
sudo make install-init
sudo make install-config
This command will install Nagios with its default settings.
Now, we need to configure the Nagios user account and the Apache web server.
Run the following command to create a Nagios user and group:
sudo useradd nagios
sudo groupadd nagcmd
sudo usermod -a -G nagcmd nagios
Next, we need to configure the Apache web server. Run the following command to create a new Apache configuration file for Nagios:
sudo touch /etc/httpd/conf.d/nagios.conf
sudo nano /etc/httpd/conf.d/nagios.conf
Add the following lines to the configuration file:
ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"
<Directory "/usr/local/nagios/sbin">
Options ExecCGI
AllowOverride None
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
</Directory>
Alias /nagios "/usr/local/nagios/share"
<Directory "/usr/local/nagios/share">
Options None
AllowOverride None
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
</Directory>
Save and close the file.
Next, we need to create an Apache password file for Nagios users. Run the following command:
sudo htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
This command will create a new password file and add a Nagios administrator account.
Finally, we need to restart the Apache web server to apply the changes. Run the following command:
sudo service httpd restart
After configuring Apache, you can access the Nagios web interface at http://<Server-IP-Address>/nagios/. Log in using the Nagios administrator account you created earlier.
That's it! You have successfully installed Nagios on Void Linux and configured the Nagios web interface. You are now ready to start monitoring your network, servers, and applications.
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!
