Ubuntu 18.04 Two vital modules are missing

I’ve now made a third clean install. All is almost working but two vital modules are missing.

Process management: Without this module, the second is not working… UCL, User Control Panel.

Recommended steps (Run from the CLI)

  • fwconsole ma install pm2
  • fwconsole ma enable pm2

How do I install these things!? I’ve done some notes: http://freepbx.tilda.ws/

“Thank God it’s Friday” :slight_smile: Hopefully we get this up and running next week…!

What version of node do you have installed? (node -v)

[email protected]:~$ node -v

My SIP-app from the phone does not connect and it’s a surprise to me because that part was easy earlier.

I’ve written some Ubuntu 18.04-related notes at the bottom of the page and also added some photos that were missing.

I’m seriously considering installing all on Ubuntu 20.04, since all was actually working on that platform… apart from PHP7 because I was too fast installing things. (I assume!!) Now I know the procedure! :slight_smile:

Debian 11 Asterisk 16, but add your own compile of zastrridk 18


See comments theretoo.

Thank you for taking the time to post this link!
I read the specs: “PHP 7.4, standard with Debian Bullseye”

I got the impression PBX is not compatible with PHP 7.4, or does that vary from OS to OS!?
I’m trying a new install, Ubuntu 20.04 this time, and I just want to make sure to install the correct version of PHP.

But at the other hand, I now see that PHP 8.0 is the latest version of PHP for Ubuntu.

I’m going along with the install. PHP and Node are important to not have too late versions…

" Step 5 – Install FreePBX"
“FreePBX requires Apache webserver, MariaDB and PHP version 7.2 to be installed in your server. By default, Ubuntu 20.04 ships with PHP version 7.4, so you will need to install the PHP Ondrej repository to your server. You can add it with the following command:”

Just checking versions for php and node.
