## Requirements
### Operating system and web server
Shaarli makes outbound HTTP/HTTPS connections to websites you bookmark to fetch page information (title, thumbnails), the server must then have access to the Internet as well, and a working DNS resolver.
+--------------------------------------------------------------------------------
### PHP
We recommend setting up [HTTPS](https://en.wikipedia.org/wiki/HTTPS) on your webserver for secure communication between clients and the server.
+### Let's Encrypt
+
For public-facing web servers this can be done using free SSL/TLS certificates from [Let's Encrypt](https://en.wikipedia.org/wiki/Let's_Encrypt), a non-profit certificate authority provididing free certificates.
- [How to secure Apache with Let's Encrypt](https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-debian-10)
sudo systemctl start nginx
```
+On apache `2.4.43+`, you can also delegate LE certificate management to [mod_md](https://httpd.apache.org/docs/2.4/mod/mod_md.html) [[1](https://www.cyberciti.biz/faq/how-to-secure-apache-with-mod_md-lets-encrypt-on-ubuntu-20-04-lts/)] in which case you don't need certbot and manual SSL configuration in virtualhosts.
+
+### Self-signed
+
If you don't want to rely on a certificate authority, or the server can only be accessed from your own network, you can also generate self-signed certificates. Not that this will generate security warnings in web browsers/clients trying to access Shaarli:

## Examples
-The following examples assume a Debian-based operating system is installed. On other distributions you may have to adapt details such as package installation procedures, configuration file locations, and webserver username/group (`www-data` or `httpd` are common values).
-
-In these examples we assume the document root for your web server/virtualhost is at `/var/www/shaarli.mydomain.org/`:

### Nginx
This examples uses nginx and the [PHP-FPM](https://www.digitalocean.com/community/tutorials/how-to-install-linux-nginx-mariadb-php-lemp-stack-on-debian-10#step-3-%E2%80%94-installing-php-for-processing) PHP interpreter. Nginx and PHP-FPM must be running using the same user and group, here we assume the user/group to be `www-data:www-data`.
bantime = -1
```
+Then restart the service: `sudo systemctl restart fail2ban`
