UPGRADE PHP7-centos7

I’m assuming that you are running a stock installation of CentOS, and already have PHP 5.4 installed.

1. VERIFY CURRENT VERSION OF PHP

Type in the following to see the current PHP version:

1

php -v

The output should match this:

1 2 3

PHP 5.4.16 (cli) (built: Apr 12 2018 19:02:01) Copyright (c) 1997-2013 The PHP Group Zend Engine v2.4.0, Copyright (c) 1998-2013 Zend Technologies

Cool, let’s move on!

2. INSTALL THE REMI AND EPEL REPOSITORIES

If you don’t already have them, install the Remi and EPEL repositories:

1 2	rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm rpm -Uvh https://rpms.remirepo.net/enterprise/remi-release-7.rpm

Enable the Remi repository globally:

1	nano /etc/yum.repos.d/remi.repo

Under the section that looks like [remi] make the following changes:

1 2 3 4 5 6 7 8

[remi] name=Remi's RPM repository for Enterprise Linux 7 - $basearch #baseurl=http://rpms.remirepo.net/enterprise/7/remi/$basearch/ #mirrorlist=https://rpms.remirepo.net/enterprise/7/remi/httpsmirror mirrorlist=http://cdn.remirepo.net/enterprise/7/remi/mirror enabled=0 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi

Type CTRL-O to save and CTRL-X to close the editor

Enable the Remi PHP7.3 Repository:

1	nano /etc/yum.repos.d/remi-php73.repo

Under the section that looks like [remi-php73] make the following changes:

1 2 3 4 5 6 7 8

[remi-php73] name=Remi's PHP 7.3 RPM repository for Enterprise Linux 7 - $basearch #baseurl=http://rpms.remirepo.net/enterprise/7/php73/$basearch/ mirrorlist=https://rpms.remirepo.net/enterprise/7/php73/httpsmirror mirrorlist=http://cdn.remirepo.net/enterprise/7/php73/mirror enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi

Make sure you un-comment the HTTPS mirror-list as well. The HTTP mirror seems to run into issues every now and then.

Type CTRL-O to save and CTRL-X to close the editor

3. UPGRADE PHP 5.4 TO PHP 7.3

Now we can upgrade PHP. Just type in the following command:

1	yum -y upgrade php*

Once the upgrade has completed, verify that you have PHP 7.3 installed:

1

php -v

Output should look like:

1 2 3

PHP 7.3.0RC5 (cli) (built: Nov  6 2018 10:22:47) ( NTS ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.3.0-dev, Copyright (c) 1998-2018 Zend Technologies

You’re now running with PHP 7.3!
