4.4 MySql and PHP

MySql and php is next for an install

-- sudo apt install mysql-client mysql-server php libapache2-mod-php

sudo apt install apache2 mysql-client mysql-server php libapache2-mod-php

To start the service

sudo service mysql start

Other commands are

sudo service mysql start
sudo service mysql stop
sudo service mysql status
sudo service mysql restart

**

The next bit is very important.

**

sudo mysql_secure_installation

This secures the MySql service. MySql must be running and this command must be run by the sudo user.

• When asked "Would you like to setup VALIDATE PASSWORD plugin?"Choose "N"
• Now set the Mysql root user (IMPORTANT do not forget that password! Write it down)
• Answer Y to "Remove anonymous users?", "Disallow root login remotely?", "Remove test database and access to it?", "Reload privilege tables now?"

Check your PHP version with:

php -v

Mine returns **PHP 7.2.19-0ubuntu0.18.04.1**. If the command returns a version of 7.3 or higher, change the version number in the following command:
<

sudo apt install graphviz aspell ghostscript clamav php7.2-pspell php7.2-curl php7.2-gd php7.2-intl php7.2-mysql php7.2-xml php7.2-xmlrpc php7.2-ldap php7.2-zip php7.2-soap php7.2-mbstring

Restart Apache webserver.

sudo service apache2 restart

You may see Failed to enable APR_TCP_DEFER_ACCEPT so run

sudo service apache2 status

You should see Apache2 is running.
