Good morning, all.

This morning I received this warning when update our Nagios server (CentOS 7):

1 =====================================================================
2
3 WARNING : PHP 7.2 have reached its "End of Life" in
4 November 2020. Even, if this package includes some of
5 the important security fix, backported from 7.3, the
6 UPGRADE to a maintained version is very strongly RECOMMENDED.
7
8 =====================================================================

I found a Nagios Support Knowledgebase article with instructions to upgrade to PHP 7.2, which is what we have.

https://support.nagios.com/kb/article/n ... 7-860.html

Looking at the steps in this article, it looks like some might not be necessary. Are there instructions available specifically to upgrade from PHP 7.2 to 7.3?

Thanks in advance for your usual prompt response.

Hi,

The process is similar but you'll want to enable the repo for 7.3 and disable the other. I tested this and it worked for me but please take a VM snapshot and/or take a full backup before making any changes, or preferably run through this on a test instance before updating the production server.

Code: Select all

sudo yum-config-manager --disable remi-php72
sudo yum-config-manager --enable remi-php73

Then update the system.

Code: Select all

yum update

Re-install the Source Guardian PHP extension.

Code: Select all

cd /tmp
rm -rf /tmp/nagiosxi
wget https://assets.nagios.com/downloads/nagiosxi/xi-latest.tar.gz
tar zxf xi-latest.tar.gz
cd /tmp/nagiosxi
rm -rf /etc/php.d/sourceguardian.ini
./init.sh
sed -i '/^PHP script/d' xi-sys.cfg
sed -i '/^1)/d' xi-sys.cfg
sed -i '/^2)/d' xi-sys.cfg
sed -i '/^3)/d' xi-sys.cfg
./install-sourceguardian-extension.sh

Then restart the web server.

Code: Select all

systemctl restart httpd

Let me know if you need help or have any questions.

This is an interesting thread and I see php v8 is out since last November - will NagiosXI work if we upgrade to that or is it safer to saty on 7.3 or 7.4?

Hi techgeek,

We haven't rolled out support for PHP 8 yet, it's unlikely to work by default. We usually need to adjust some to the other packages/settings for major updates.

Thanks that is good to know - does Nagiosxi work with 7.4?

Posted: **Fri Apr 30, 2021 9:51 am**

Good question. Yes, Nagios XI will run in PHP 7.4 as long as you're using Nagios XI 5.7.0 or later.

Supported PHP versions for Nagios XI:

5.3, 5.4, 5.5, 5.6
7.0, 7.1, 7.2 (XI 5.5+)
7.3 (XI 5.6.8+)
7.4 (XI 5.7.0+)

Sorry I didn't reply sooner -- the upgrade went well. Thanks for your help!
