Sorry for late reply.

Upgrading php its distro based, so cant help you much on that.

What I did in my centos 7 was to add a repo that had >php7.3 then upgrade that package

42

@TheGreatDoc No problem, thanks for getting back to me. I’m not a linux expert, I’m not sure how to do what you did. Is it possible to backup my config, rebuild the VM using an up to date version of linux and then import my settings? I’d like to keep my data/history and sensors.

Thanks.

@dt-lib what distro are you running?

And yes, you can backup all your data and change server https://docs.librenms.org/Support/FAQ/#how-do-i-move-my-librenms-install-to-another-server

@TheGreatDoc

i haven’t ran apt-get update and apt-get upgrade in a while, will that update php to the latest version?

EDIT- I don’t see PHP in the list

@TheGreatDoc

What about upgrading my current install to 20.04.1 LTS? I see this when I login.

69 packages can be updated.
0 updates are security updates.

New release ‘20.04.1 LTS’ available.
Run ‘do-release-upgrade’ to upgrade to it.

46

@TheGreatDoc

Thanks for providing that link. I was hoping for some type of export option, but it appears to be a bit more complicated (for me) than that.

47

I never had good experiences doing a release-upgrade.

Check this: https://computingforgeeks.com/how-to-install-php-on-ubuntu/ to install php 7.4 in ubuntu 18

48

@dt-lib
release-upgrade worked well for 6 servers here, but was always done in a virtual machine environnement with a snapshot taken before, and ready in case a rollback is needed.

Ensure that the server is perfectly upgraded in its current release, run “apt autoremove” before, and ensure that you have more than enough disk space to run the upgrade. That should be safe.

@PipoCanaja @TheGreatDoc
I tried the upgrade to 20.04 and it completed, but when I try to launch the librenms web page, I get this:

<?php /** * Laravel - A PHP Framework For Web Artisans * * @author Taylor Otwell */ /* |-------------------------------------------------------------------------- | Register The Auto Loader |-------------------------------------------------------------------------- | | Composer provides a convenient, automatically generated class loader for | our application.

Thanks.

Make sure php is installed and enabled

52

thats php-cli, and you also want the apach2/fpm one

53

@TheGreatDoc

I’m not sure what I need to do from here.

54

Im not running LibreNMS in Ubuntu, but try sudo apt install php libapache2-mod-php

55

Thanks, that got me to this when I tried launching librenms

Missing PHP extensions. Please install and enable them on your LibreNMS server.
mysqlnd

56

@TheGreatDoc
I ran this, sudo apt-get install -y php- mysqlnd and now I see this

Missing PHP extensions. Please install and enable them on your LibreNMS server.

mbstring
curl
xml
gd

I guess this is similar to the mysqlnd, I’ll see how to get those installed.

edit- I’m getting too many mixed results when searching for how to install curl, xml, gd and mbstring. It seems that something is broken or I’m doing something wrong.

edit2- I restored to the snapshot just prior to the 20.04 upgrade. I’ll be leaving the server as is, no more updates because of the PHP issue, I can’t get past that. Thanks to all of your assistance @TheGreatDoc I really do appreciate all of your help.

57

Instead upgrading whole distro, try the link I posted before to install php7.4 in Ubuntu18

58

Ok, here is where I’m at after I run the first few commands, I have not proceeded yet.

You can get more information about the packages at https://deb.sury.org

I proceeded by pressing enter, followed all the commands on that page, now I’m at (when I try to launch librenms)…
