||||
|
||||
Installs and configures the **latest available Zabbix LTS release** on Ubuntu 24.04 Server.
|
||||
|
||||
This is a **production-focused installer**, not a demo.
|
||||
|
||||
It assumes Nginx, PHP-FPM, and MariaDB are already installed and running.
|
||||

|
||||
|
||||
If you don’t have the required components, you can use these compatible installers:
|
||||
|
||||
- [Nginx + PHP-FPM Installer](https://git.x-files.dk/webserver/nginx-ubuntu)
|
||||
- [MariaDB Installer](https://git.x-files.dk/database/mariadb-ubuntu)

||||
### Download the Script
|
||||
|
||||
Clone this repository to your server:
|
||||
|
||||
```
|
||||
git clone https://git.x-files.dk/network/zabbix-ubuntu.git
|
||||
```
|
||||
|
||||
```
|
||||
cd zabbix-ubuntu
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Usage
|
||||
|
||||
Run the script using:
|
||||
|
||||
```
|
||||
sudo ./zabbixinstall -n <domain> -p <zabbix db password> [options]
|
||||
```
|
||||
|
||||
### Examples
|
||||
|
||||
The installer automatically detects if socket authentication is active. Only include `-a` and `-m` if your MariaDB setup does **not** use socket authentication.
|
||||
|
||||
```
|
||||
sudo ./zabbixinstall -n zabbix.example.com -p zabbixdbpwd
|
||||
sudo ./zabbixinstall -n zabbix.example.com -p zabbixdbpwd -m rootpwd
|
||||
sudo ./zabbixinstall -n zabbix.example.com -p zabbixdbpwd -a admin -m adminpwd
|
||||
```
|
||||
|
||||
### Options
|
||||
|
||||
| Flag | Description |
|
||||
|------|--------------|
|
||||
| `-p <password>` | Zabbix database user password |
|
||||
| `-a <username>` | Optional MariaDB admin username (defaults to `root` if not specified) |
|
||||
| `-m <password>` | MariaDB root or admin password — *required only if socket authentication is disabled* |
|
||||
| `-h`, `--help` | Show the help screen (reflects detected socket status) |
|
||||
|
||||
### Configuration
|
||||
|
||||
Once the installer completes, visit:
|
||||
|
||||
```
|
||||
http://<domain>
|
||||
```
|
||||
|
||||
And complete the setup.

### Features
|
||||
|
||||
- Installs and configures Zabbix LTS automatically
|
||||
- Creates the MariaDB database and user with the correct privileges
|
||||
- Enables and starts Zabbix server and agent services
|
||||
- Detects MariaDB socket or password authentication automatically
|
||||
- Generates an Nginx host configuration dynamically
|
||||
- Integrates cleanly with PHP-FPM and Nginx setups
|
||||
- Supports re-runs via `IF NOT EXISTS` logic for safe idempotency

### Configuration Details
|
||||
|
||||
#### File Locations
|
||||
|
||||
| File | Description |
|
||||
|------|--------------|
|
||||
| `/etc/zabbix/zabbix_server.conf` | Main Zabbix server configuration file |
|
||||
| `/usr/share/zabbix-sql-scripts/mysql/server.sql.gz` | Database schema file imported by installer |
|
||||
| `/etc/nginx/conf.d/<domain>.conf` | Generated Nginx host configuration file |
|
||||
| `/etc/nginx/nginx-snippets` | Shared include snippets and templates |
|
||||
|
||||
---
|
||||
|
||||
#### Behavior
|
||||
|
||||
- The installer checks if **MariaDB socket authentication** is active.
|
||||
If available, it connects locally as `root` (no password).
|
||||
- If socket authentication is **not detected**, use `-a` and `-m` to supply credentials.
|
||||
- Automatically sets and resets `log_bin_trust_function_creators` during import.
|
||||
- Nginx configuration is validated (`nginx -t`) before restarting.
|
||||

|
||||
|
||||
### Nginx Integration
|
||||
|
||||
The generated Zabbix configuration file listens on port 80.
|
||||
To enable HTTPS (port 443), use the example provided [here](https://git.x-files.dk/webserver/nginx-snippets/src/branch/main/hostfiles/zabbix.443.conf).
|
||||
|
||||
> **NOTE**
|
||||
> The file also includes optional caching directives (commented out by default).
|
||||
> You can enable them to improve load times and performance if needed.
|
||||
> The lines you are looking for are at the bottom of the generated config file and look like this:
|
||||
> ```
|
||||
> ##### Cache js css static content and open files start #####################
|
||||
> # include /etc/nginx/nginx-snippets/cache-open-files.conf;
|
||||
> # include /etc/nginx/nginx-snippets/cache-statics.conf;
|
||||
> # include /etc/nginx/nginx-snippets/cache-js-css.conf;
|
||||
> ##### Cache js css static content and open files stop ######################
|
||||
|

|
||||
|
||||
### Troubleshooting
|
||||
|
||||
**Nginx fails to restart**
|
||||
Run `nginx -t` and review any syntax errors reported in `/etc/nginx/conf.d/<domain>.conf`.
|
||||
|
||||
**Access denied during database creation**
|
||||
Your MariaDB setup likely does not use socket authentication.
|
||||
Re-run the installer with the `-m` flag (and optionally `-a`) to provide credentials.
|
||||
The installer will automatically re-detect your configuration.
|
||||
|
||||
**PHP version mismatch**
|
||||
The script automatically detects your installed PHP version,
|
||||
but ensure that the PHP-FPM service (e.g., `php8.3-fpm`) is active.
|
||||
|
||||
**Schema import fails**
|
||||
Verify that `/usr/share/zabbix-sql-scripts/mysql/server.sql.gz` exists.
|
||||
If missing, reinstall the `zabbix-sql-scripts` package.

### FAQ
|
||||
|
||||
**Q:** Why doesn’t the script ask for a MariaDB password by default?
|
||||
**A:** Ubuntu 24.04’s MariaDB defaults to *socket authentication*,
|
||||
allowing the local `root` user to connect without a password.
|
||||
The installer detects this automatically and skips password prompts when applicable.
|
||||
|
||||
**Q:** Can I run the installer multiple times?
|
||||
**A:** Yes. Database and user creation use `IF NOT EXISTS`, making re-runs safe.
|
||||
Existing Nginx configuration files are replaced, but no data is deleted.
|
||||
|
||||
**Q:** Does this modify existing Nginx settings?
|
||||
**A:** No. It adds a standalone host file in `/etc/nginx/conf.d/`
|
||||
and validates configuration changes before applying them.
