For this installation we will assume that we are working on AlmaLinux 8 or 9. Warning: This guide does not cover any security hardening or rate limiting.
Note: These steps also work with AlmaLinux 9, but it will install PHP 8 instead of 7.
3. Enable and start Apache/PHP-FPM: `systemctl enable httpd; systemctl enable php-fpm` and `systemctl start httpd; systemctl start php-fpm`.
4. Let's help MTR to work, execute the following command: `ln -s /usr/sbin/mtr /usr/bin/mtr` and also mtr helper called mtr-packet: `ln -s /usr/sbin/mtr-packet /usr/bin/mtr-packet`.
5. You *must* configure SELinux before this all works, or you can disable SELinux using `setenforce 0` and possibly make it permanent: `nano /etc/selinux/config` change to `SELINUX=disabled`.
6. Upload the contents of the ZIP to /var/www/html/.
7. Rename config.dist.php to config.php and adjust the settings.
8. (Optional) You might want to enable SSL using LetsEncrypt, take a look at [acme.sh](https://github.com/acmesh-official/acme.sh).
### Customization
If you open up config.dist.php you will see that there are some features that allows you to customize the looking glass, this includes a custom CSS override.
You may also extend the looking glass with a custom block.
### TODO
- Move to Composer;
- Software-based rate limiting;
- Implement a template engine, for advanced customization;
We would love to receive code contributions in the form of a pull request. We prefer this over forking, so if you have any code improvements feel free to commit.
This project is inspired by the [LookingGlass project](https://github.com/telephone/LookingGlass) of @telephone and uses his procExecute() function, although slightly modified.
