One of the most important components for WordPress is PHP.  I recommend going on the latest version 7.3.  Below are easy to follow instructions for accomplishing it.

See the WordPress page for some other php fixes. 

This is what I use to install PHP for WordPress.

sudo apt install php7.3 libapache2-mod-php7.3 php7.3-common php7.3-mysql php7.3-gmp php7.3-curl php7.3-intl php7.3-mbstring php7.3-xmlrpc php7.3-gd php7.3-xml php7.3-cli php7.3-zip

I have been working on better securing my web sites in WP.   I installed the Health Check plugin. 

It checked the php components and found a few missing. CURL, which I had installed so I refollowed these steps to verify it for php 7.3

  1. First Install CURL by typing sudo apt-get install curl

  2. Then Restart Apache by typing sudo service apache2 restart

  3. Then Install PHP5 CURL by typing sudo apt-get install php7.3-curl

  4. will prompt to install… type y or yes!

  5. Then Restart Apache by typing sudo service apache2 restart

  6. Done!  It now shows up in phpMyAdmin.

I have upgraded to the latest LAMP components that you are read about on Ubuntu pages.   I am on the latest version of WordPress.   This mainly affects my main webpage with videos of my children.  These files can be huge. 


upload_max_filesize = 768M
post_max_size =768M
memory_limit = 768M
max_execution_time = 360

Health Check said these two components were missing.  fpm had some errors too.

sudo apt-get install php7.3-bcmath
sudo apt-get install php7.3-imagick

I ran the commands below in various order to fix fpm

sudo a2enmod proxy_fcgi setenvif
sudo a2enconf php7.3-fpm

sudo apt purge libapache2-mod-php7.3 libapache2-mod-php
sudo apt install libapache2-mod-php7.3 libapache2-mod-php

After I fixed these errors, I ran update and dist-upgrade again to get the latest versions. 

WordPress 5.x works great with PHP 7.3 and above.   PHP 7.3 performance increases have been well documented. 

9.6.2019: Multiple Code Execution Flaws Found In PHP Programming Language

The PHP security team has addressed the vulnerabilities in the latest versions. So users and hosting providers are strongly recommended to upgrade their servers to the latest PHP version 7.3.9, 7.2.22, or 7.1.32.

The configuration file now needs a secret passphrase (blowfish_secret).

phpMyAdmin blowfish secret generator

In /usr/share/phpMyAdmin rename to  Use the link above to generate the line of code to add to this file. Change this line with the code that link gives you. 

$cfg[‘blowfish_secret’] = ”; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */

The $cfg[‘TempDir’] (./tmp/) is not accessible

create tmp under /usr/share/phpMyAdmin.   I use chmod 755 and chown www-data:www-data so Apache can use it.  I am not a big fan of 777 for it.

 phpMyAdmin Homepage

Many of the articles I read on MYSQL and MariaDB mentioned phpMyAdmin to create databases and users.   I have a notepad++ page filled with scripts to created WP databases and users.   I started off installing the base Ubuntu phpMyAdmin 4.5.4.   I added the repository for 4.6.    I went to their main site and downloaded the tar file for 4.8.5 because it fixed errors on the pages.   It was a manual install.  I just upgraded to 4.9.1 and rebooted. 

You will find  phpMyAdmin-4.9.1-all-languages.tar.gz  on the list.  Right click and copy link.  You will get this

tar xvzf phpMyAdmin-4.9.1-english.tar.gz
sudo cp -avr ./phpMyAdmin-4.9.1-english/. /usr/share/phpmyadmin

I did a wget in the /usr/share/phpmyadmin folder.   The tar command will unzip it into its own folder.   cp -Rf the contents into the folder above it.    Restart Apache.  

phpMyAdmin allows me a tool to create databases and users with ease.   I created a sa account and gave root limited access.   I moved phpMyAdmin off port 80 to another port.   It required a few basic steps of creating a Sites-Available file and removing the mods-enable configuration.  Both WP servers are now on this port.  

The main screen of phpMyAdmin shows you the databases on the left.  The versions of Apache, MySQL (MariaDB), and php on the right.  It also shows you the version of phpMyAdmin running.

I decided to setup a new database to parse out the Firewall Syslogs.  I created a new page for the Fortinet 60E hardening to show the results of this database.  pMyAdmin allows for the easy creation of databases, tables and setting up the user for the database.   Once you setup a unique table field, you can even edit, create and delete rows of data. 

In order for LOAD DATA LOCAL INFILE to work in your php code you need a few config file changes:

modify php.ini files in these directories.
