How to upgrade to PHP 7.4 on Ubuntu

You should upgrade your PHP for your server to version 7.4 or higher for security reasons. You can find PHP version info from here: Here I am doing an upgrade from PHP version 7.2 to 7.4 on my Ubuntu server, before you do any changes, make sure you have a good backup of your server/application which may be running on your server.

To see current version:

command: php -version
output: PHP 7.2.24-0ubuntu0.18.04.7 and some other details of your server

First, make sure your server is up to date by running the following commands:
Command: apt update
Command: apt-upgrade

Then add repository to install PHP:

Command: add-apt-repository ppa:ondrej/php
Command: apt update

You will get message like this to continue or cancel:

To install PHP7.4

Command: apt install php7.4

To see the version you can re-run the command:

Command: php -version
Output: PHP 7.4.14 with some other info

Now you have the PHP 7.4 on your server you can update your application to take effect of newer version of PHP. Here is example of web server apache

Command: sudo a2enmod php7.4

Considering dependency mpm_prefork for php7.4:
Considering conflict mpm_event for mpm_prefork:
ERROR: Module mpm_event is enabled – cannot proceed due to conflicts. It needs to be disabled first!
Considering conflict mpm_worker for mpm_prefork:
ERROR: Could not enable dependency mpm_prefork for php7.4, aborting

To fix:

Command: sudo a2dismod mpm_event

Module mpm_event disabled.
To activate the new configuration, you need to run:
systemctl restart apache2

Before you restart, you will need to activate PHP7.4, otherwise you will get this error:

Command: sudo systemctl restart apache2

Install PHP 7.4 Extensions

Installing PHP extensions are simple with the following syntax.
Command: sudo apt install php7.4-extension_name

Here are some commonly used php-extensions:

php7.4-common php7.4-mysql php7.4-xml php7.4-xmlrpc php7.4-curl php7.4-gd php7.4-imagick php7.4-cli php7.4-dev php7.4-imap php7.4-mbstring php7.4-opcache php7.4-soap php7.4-zip php7.4-intl

For PHP 7.4 with Apache the php.ini location will be in following directory.
sudo nano /etc/php/7.4/apache2/php.ini

For PHP 7.4 FPM with Nginx the php.ini location will be in following directory.
sudo nano /etc/php/7.4/fpm/php.ini

To search with nano editor: F6 or CTR+W and update the following values for better performance.

upload_max_filesize = 32M 
post_max_size = 48M 
memory_limit = 256M 
max_execution_time = 600 
max_input_vars = 3000 
max_input_time = 1000

For web server to take effect restart the service:
Command: sudo systemctl restart apache2

Finally doing clean up of old stuff no longer needed:

Command: apt autoremove

That’s should it, if you have other applications you just have to update that, some may automatically be done, no other action needed. You should test everything to make sure all functioning well.

Moving your WordPress site to new server via All-in-one WP Migration

Here is another way of moving your new WordPress site to a new server.  I had written one post called How to move your WordPress site to a new server which was the manual way of doing, without the use of any plugin, like this one called All-in-One WP Migration.  It’s a very simple process to do move using this plugin, please make sure you have a good backup before doing anything.  I like said before, use whatever you feel comfortable.  As always I do recommend doing a full backup of your site file and database, just in case you need to go back to it.  In this post, will go through the whole process of moving your WordPress site, using third party plugin called All-in-One WP Migration. Remember, using this third-party plugin is easier, but have to be aware, it may have the restriction on function/size of database or type, which may change at any time.

I am assuming you already have a good working website, permission, and backup.  Will keep this simple and jump right onto moving site.

Install a plugin called All-in-One WP Migration by going to your WordPress admin panel and clicking on Plugins tab>Then Plugins Add New

Search: all in one WP, once you find it click Install, then Activate it.

Then let’s create a backup using the new All-in-one WP Migration plugin, by clicking on Create Backup under All-in-one WP Migration plugin

It will give you many options where you want to back up to, I am going to select the file

Once, it finishes back up it will give you the option to download it, click on it and save, then click close.

In case you want to download the backup via FTP/SFTP: \wp-content\ai1wm-backups

Then log in to the new WordPress site and install the same plugin installation

Now let’s import your data to the new site

Go to All-in-one WP Migration Plugin>Import>Then select the file and find your backup

You will get this warning if you are ready to override, click Proceed

Once it’s done, you should see Successfully message

That’s it.
