## Zabbix install script for Ubuntu 22.04 and 24.04 server.
|
||||
|
||||
### Prerequisites
|
||||
Ubuntu 22.04 or higher with Nginx and MariaDB. Nginx can be installed from
|
||||
[\[Here\]](https://git.x-files.dk/ubuntu-web-server/nginx-install)
|
||||
and MariaDB can be install from
|
||||
[\[Here\]](https://git.x-files.dk/ubuntu-database-server/mariadb-install)
|
||||
|
||||
### Download the script
|
||||
```
|
||||
git clone https://git.x-files.dk/ubuntu-web-application/zabbix-install.git
|
||||
```
|
||||
|
||||
### Usage
|
||||
cd zabbix-install
|
||||
sudo ./zabbixinstall [-n] <domain name> [-p] <zabbix database pwd>
|
||||
|
||||
### Example
|
||||
sudo ./zabbixinstall -n zabbix.something.xyz -p zabbixdatabasepwd
|
||||
|
||||
This will create a Zabbix site running on port 80 with the domain name you chose under the installation.
|
||||
Don't worry though this can easily be fixed by modifying the Nginx configuration later.
|
||||
If you need an example on how to configure Nginx to run this on port 443 I an example
|
||||
[\[Here\]](https://git.x-files.dk/ubuntu-web-server/nginx-install/src/branch/main/cfg-apps/zabbix.443.conf)
|
||||
|
||||
### Configuration
|
||||
Once the script is done browse to http://<i></i>zabbix.something.xyz and fill out the mandatory fields marked with green.

||||

||||
<p align="center" width="100%"><img src="https://git.x-files.dk/assets/zabbix-configuration2.png" alt="Zabbix Configuration"/></p>
|
||||
<p align="center" width="100%"><img src="https://git.x-files.dk/assets/zabbix-configuration3.png" alt="Zabbix Configuration"/></p>
|
||||
|
||||
**Post install:**\
|
||||
Nothing to do.
|
||||
|
||||
### Troubleshooting
|
||||
Most issues will probably be caused by the fact that we all set up and configure Nginx diffrently. If you encounter problems I would suggest you look at the Nginx configuration I use
|
||||
[\[Here\]](https://git.x-files.dk/ubuntu-web-server/nginx-install/src/branch/main/cfg/nginx.conf)
|
||||
and also the default "sites-enabled" Nginx configurarion I use
|
||||
[\[Here\]](https://git.x-files.dk/ubuntu-web-server/nginx-install/src/branch/main/cfg/default)
|
||||
when you start troubleshooting.
|
||||
|
||||
### More guides
|
||||
More guides can be found on [\[wiki.x-files.dk\]](https://wiki.x-files.dk)
|
||||
|
||||
### Last tested
|
||||
October 10th 2024 on Ubuntu 24.04.
