LibreNMS upgrade PHP from 7.2 to 7.4 – CentOS 7

First you’ll need to install the remi repo

sudo wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
sudo wget http://rpms.remirepo.net/enterprise/remi-release-7.rpm
rpm -Uvh remi-release-7.rpm epel-release-latest-7.noarch.rpm

You’ll need to install yum-utils, disable all old php versions, and enable the remi-php74

sudo yum install -y yum-utils
sudo yum-config-manager --disable remi-php56
sudo yum-config-manager --disable remi-php71
sudo yum-config-manager --disable remi-php72
sudo yum-config-manager --disable remi-php73
sudo yum-config-manager --enable remi-php74

If you run into issues you may want to see if you have the webtatic repo installed. I had to disable it to get php to update.

vi /etc/yum.repos.d/webtatic
[webtatic]
name=Webtatic Repository EL7 - $basearch
baseurl=https://repo.webtatic.com/yum/el7/$basearch/
mirrorlist=https://mirror.webtatic.com/yum/el7/$basearch/mirrorlist
failovermethod=priority
enabled=0   <- Disabled by changing to a 0
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-webtatic-el7

And running the yum update should update it to php 7.4

sudo yum update

Had some problems where the Sonar Poller Stopped working. Think some packages got removed so trying to run 

sudo php /opt/poller/bin/checkForUpgrades.php

Returned a php error that it was not installed. Installed it with all the other dependencies to fix the problem.

Note that php version is different then it is on the github page. php7.2-cli is installed instead of php7.0-cli.

sudo apt-get install php7.2-cli php-zip php-snmp php-sqlite3  php-bcmath php-mbstring php-dom git fping snmp redis-server monit ntp  snmp-mibs-downloader

LibreNMS Error: Missing dependencies! Run the following command to fix:

Received this error while trying to access LibreNMS in web browser.

Error: Missing dependencies! Run the following command to fix:

./scripts/composer_wrapper.php install –no-dev

 

Tried sshing into the LibreNMS server and running the script, but that didn’t fix the issue.

Ran ./validate.php and it came up with the some of the following errors.

[FAIL] Missing PHP extension: mbstring
[FIX] Please install mbstring
[FAIL] The poller (localhost.localdomain) has not completed within the last 5 minutes, check the cron job.
[WARN] Your install is over 24 hours out of date, last update: Thu, 7 May 2018 19:18:35 +0000
[FIX] Make sure your daily.sh cron is running and run ./daily.sh by hand to see if there are any errors.

Installed mbstring.  You may need to change the number if yum is complaining about package conflicts.  Use “yum search mbstring” to show all the versions available.

yum install php71w-mbstring

Ran ./validate.php again and it wanted this script run

./scripts/composer_wrapper.php install --no-dev

Restart Apache

systemctl restart httpd
