qgis - Installing Lizmap with PostgreSQL

I've been trying to install the Lizmap webclient. I was following this guide. I've successfully came to the part where I have to set up my config files.

I am suspecting the error lies within my profiles.ini.php configuration file, but for some reason I can't find out why.

This is my profiles.ini.php that I've edited to match my PostgreSQL requirements:

;for security reasons, don't remove or modify the first line

After this edit of the profiles.ini I try running php installer.php and get the following error:

[error] An error occured during the installation of the module jacl2db: error during the connection localhost

I should note that if I use the SQLite settings the Lizmap installs correctly, but since for this project I am using PostgreSQL, I would like to use the same database.

So how can I install Lizmap webclient alongside PostgreSQL?

Answer

After playing around with settings I've figured it out. The problem was with the definition, I didn't add the port number so after I added 2 lines:

[jdb:jauth]
driver="pgsql"

database="lizmap"
host="localhost"
port=5678
user="dummyuser"
password="dummypass"

[jdb:lizlog]
driver="pgsql"
database="lizmap"
host="localhost"

port=5678
user="dummyuser"
password="dummypass"

And when I reran the installer.php the Installation successfully ended.

NOTE: As Vince suggested it is dangerous to database integrity to connect as the postgres user for any purpose outside of database administration, therefore we should create a new user:

Creating a "superuser" user

su - postgres createuser dummyuser --superuser

Modifying passwords

psql ALTER USER postgres WITH ENCRYPTED PASSWORD '************'; ALTER USER dummyuser WITH ENCRYPTED PASSWORD 'dummypass'; \q
