# Install on NGINX
<h1 align=center>Installation of 4get in NGINX</h1>
>I do NOT recommend following this guide, only follow this if you *really* need to use nginx. I recommend you use the apache2 steps instead.
<div align=right>
Login as root.
> NOTE: As the previous version stated, it is better to follow the <a href="https://git.lolcat.ca/lolcat/4get/src/branch/master/docs/apache2.md">Apache2 guide</a> instead of the Nginx one.
Create a file in `/etc/nginx/sites-avaliable/` called `4get.conf` or any name you want and put this into the file:
> NOTE: This is going to guess that you're using either a <abbr title="(Arch Linux, Artix Linux, Endeavouros, etc...) ">Arch-based system</abbr> or a <abbr title="(Debian, Ubuntu, Devuan, etc...)">Debian-based system</abbr>, although you can still follow it with minor issues.
</div>
1. Login as root.
2. Upgrade your system:
* On Arch-based, run `pacman -Syu`.
* On Debian-based, run `apt update`, then `apt upgrade`.
3. Install the following dependencies:
* `git`: So you can clone <a href="https://git.lolcat.ca/lolcat/4get">this</a> repository.
* `nginx`: So you can run Nginx. If using a non-systemd distribution, go to <a href=""></a>
* `php-fpm`: This is what allows Nginx to run *(and show)* PHP files.
* `php-imagick`, `imagemagick`: Image manipulation.
* `php-apcu`: Caching module.
* `php-curl`, `curl`: Transferring data with URLs.
* `php-mbstring`: String utils.
* `certbot`, `certbot-nginx`: ACME client. Used to create SSL certificates.
* In Arch-based distributions:
* `pacman -S nginx certbot php-imagick imagemagick curl php-apcu git`
* In Debian-based distributions:
* `apt install php-mbstring nginx certbot php-imagick imagemagick php-curl curl php-apcu git`
<div align=right>
> IMPORTANT: `php-curl`, `php-mbstring` might be a Debian-only package, but this needs further fact checking.
> IMPORTANT: `php-apcu` is known to not work on Artix[^1].
</div>
4. `cd` to `/etc/nginx` and make the `conf.d/` if it doesn't exist:
* Again, this guesses you're logged in as root.
```sh
cd /etc/nginx
ls -l conf.d/ # If ls shows conf.d, then it means it exists.
# If it does not, run:
mkdir conf.d
```
5. Make a file inside `conf.d/` called `4get.conf` and place the following content:
* First run `touch conf.d/4get.conf` then `nano conf.d/4get.conf` to open the nano editor: *(Install it if it is not, or use another editor.)*
```sh
server {
# DO YOU REALLY NEED TO LOG SEARCHES?
access_log /dev/null;
error_log /dev/null;
# Change this if you have 4get in other folder.
access_log /dev/null; # Search log file. Do you really need to?
error_log /dev/null; # Error log file.
# Change this if you have 4get in another folder.

That is a very basic config so you will need to adapt it to your needs in case you have a more complicated nginx configuration. Anyways, you can see a real world example [here](https://git.zzls.xyz/Fijxu/etc-configs/src/branch/selfhost/nginx/sites-available/4get.zzls.xyz.conf)
After you save the file you will need to do a symlink of the `4get.conf` file to `/etc/nignx/sites-enabled/`, you can do it with this command:
* The above is a very basic configuration and thus will need tweaking to your personal needs. It should still work as-is, though. A 'real world' example is present in [^2].
* After saving the file, check that the `nginx.conf` file inside the main directory includes files inside `conf.d/`:
* It should be inside the the http block: *(The following is an example! Don't just Copy and Paste it!)*
```sh
ln -s /etc/nginx/sites-available/4get.conf /etc/nginx/sites-available/4get.conf
http {
include mime.types;
include conf.d/*.conf;
types_hash_max_size 4096;
# ...
}
```
* Now, test your configuration with `nginx -t`, if it says that everything is good, restart *(or start)* the Nginx daemon:
* This depends on the init manager, most distributions use `systemd`, but it's better practice to include most.
```sh
# systemd
systemctl stop nginx
systemctl start nginxt
# or
systemctl restart nginx
Now test the nginx config with `nginx -t`, if it says that everything is good, restart nginx using `systemctl restart nginx`
# openrc
rc-service nginx stop
rc-service nginx start
# or
rc-service nginx restart
# Encryption setup
# runit
sv down nginx
sv up nginx
# or
sv restart nginx
Generate a certificate for the domain using:
# s6
s6-rc -d change nginx
s6-rc -u change nginx
# or
s6-svc -r /run/service/nginx
# dinit
dinitctl stop nginx
dinitctl start nginx
# or
dinitctl restart nginx
```
6. Clone the repository to `/var/www`:
* `git clone --depth 1 https://git.lolcat.ca/lolcat/4get 4get` - It clones the repository with the depth of one commit *(so it takes less time to download)* and saves the cloned repository as '4get'.
7. That should be it! There are some extra steps you can take, but it really just depends on you.
<h2 align=center>Encryption setup</h2>
1. Generate a certificate for the domain you're using with:
* Note that `certbot-nginx` is needed.
```sh
certbot --nginx --key-type ecdsa -d www.yourdomain.com -d yourdomain.com
```
(Remember to install the nginx certbot plugin!!!)
2. After that, certbot will deploy the certificate automatically to your 4get conf file; It should be ready to use from there.
After doing that certbot should deploy the certificate automatically into your 4get nginx config file. It should be ready to use at that point.
<h2 align=center>Tor Setup</h2>
# Tor setup on NGINX
<div align=right>
Important Note: Tor onion addresses are significantly longer than traditional domain names. Before proceeding with Nginx configuration, ensure you increase the `server_names_hash_bucket_size` value in your `nginx.conf` file. This setting in your Nginx configuration controls the internal data structure used to manage multiple server names (hostnames) associated with your web server. Each hostname requires a certain amount of memory within this structure. If the size is insufficient, Nginx will encounter errors.
> IMPORTANT: Tor onion addresses are very long compared to traditional domains, so, Before doing anything, edit `nginx.conf` and increase <abbr title="This setting in your Nginx configuration controls the internal data structure used to manage multiple server names (hostnames) associated with your web server.

1. Open your `nginx.conf` file (that is under `/etc/nginx/nginx.conf`).
2. Find the line containing `# server_names_hash_bucket_size 64;`.
3. Uncomment the line and adjust the value. Start with 64, but if you encounter issues, incrementally increase it (e.g., 128, 256) until it accommodates your configuration.
</div>
Open your current 4get NGINX config (that is under `/etc/nginx/sites-available/`) and append this to the end of the file:
```
1. `cd` to `/etc/nginx` *(if you haven't)* and open your `nginx.conf` file.
2. Find the line containing `# server_names_hash_bucket_size 64;` inside said file.
3. Uncomment the line and adjust the value; start with 64, but if you encounter issues, incrementally increase it *(e.g., 128, 256)* until it accommodates your configuration.
4. Open *(or duplicate the configuration)* and edit it:
* Example configuration, again:
```sh
server {
access_log /dev/null;
error_log /dev/null;
access_log /dev/null; # Search log file. Do you really need to?
error_log /dev/null; # Error log file.

A real world example is present in [^2].
5. Once done, check the configuration with `nginx -t`. If everything's fine and dandy, refer to <a href="https://git.lolcat.ca/lolcat/4get/src/branch/master/docs/tor.md">the Tor guide</a> to setup your onion site.
Obviously replace `<youronionaddress>` by the onion address of `/var/lib/tor/4get/hostname` and then check if the nginx config is valid with `nginx -t` if yes, then restart the nginx service and try opening the onion address into the Tor Browser. You can see a real world example [here](https://git.zzls.xyz/Fijxu/etc-configs/src/branch/selfhost/nginx/sites-available/4get.zzls.xyz.conf)

2. <a href="https://git.lolcat.ca/lolcat/4get/src/branch/master/docs/apache2.md">Apache2 guide</a>: Fallback to this if you couldn't get Nginx to work, or you don't know something.
Once you did the above, refer to <a href="https://git.lolcat.ca/lolcat/4get/src/branch/master/docs/tor.md">this tor guide</a> to setup your onionsite.
<h2 align=center>Known issues</h2>
1. `php-apcu` not working in Artix[^1], this might be because of it being a systemd daemon, but the binary isn't present. This might apply to Arch Linux as well, since it is from where the package was gotten. Read more in the issue.
[^1]: lolcat/4get#40, It might be needed to create a boot entry, but the binary is unknown.
[^2]: <a href="https://git.nadeko.net/Fijxu/etc-configs/src/branch/selfhost/nginx/conf.d/4get.conf">git.nadeko.net</a> nadeko.net's 4get instance configuration.
