What is the default length you want generated short codes to have? (You will still be able to override this on every created short URL) [5]:

Do you want Shlink to resolve the short URL title based on the long URL's title tag (if any)? Otherwise, it will be kept empty unless explicitly provided. (yes/no) [yes]:

[enter]

Do you want Shlink to redirect short URLs as soon as the first segment of the path matches a short code, appending the rest to the long URL?

[enter]

Do you want to support short URLs with multi-segment custom slugs? (for example, https://example.com/foo/bar) [Slugs and short codes will support only one segment (https://example.com/foo). Orphan visits will have one of "base_url",

yes

yes

How do you want short URLs to be matched?
Warning! This feature is experimental. It only applies to public routes (short URLs and QR codes). REST API routes always use strict match.

then get

Error writing to "config/params/generated_config.php": file_put_contents(config/params/generated_config.php):

This is very fustrating and have spent several days trying to get this to work

Using sudo all over is likely going to cause problems down the line.

I would recommend not running all the commands under Download dist file with sudo.

[franco640]

Same issue occurs, i have done this so many times and it's very frustrating.

[acelaya]

The error is caused by missing write permissions.

[franco640]

what permissions are required ? on the params folder i have 755 - drwxr-xr-x www-data www-data params

[franco640]

also the config folder is 755 - drwxr-xr-x www-data www-data.

[franco640]

base path for the Shlink folder - Shortner-Server:/var/www/shlinkio$ cd /var/www/shlinkio/

I can do a video of the settings i'm using

[franco640]

I have it working finally.

I did not know that I had to be in the root folder of where you extracted the dist file. For myself it was

cd /var/www/shlinkio

and then run

sudo -u www-data php8.3 /var/www/shlinkio/vendor/shlinkio/shlink-installer/bin/shlink-installer install

for it to work

not great and caused me no end of grief to get this to work.

[acelaya]

Yep, that's documented here https://shlink.io/documentation/command-line-interface/installation-tool/

[franco640]

bugger, my bad. That's annoying

[franco640]

Was looking at the youtube videos when i was doing the installation. They all seem to be very outdated
