This guide will help you Install PHP 7.3 on Ubuntu 18.04 / Ubuntu 16.04 / Debian. PHP is an open-source server-side scripting language which has been widely adopted for the creation of dynamic web pages. This skeleton includes a Vagrantfile based on Ubuntu 14.04, and using the ondrej/php PPA to provide PHP 7.0. Start it up using: $ vagrant up. Once built, you can also run composer within the box. For example, the following will install dependencies: $ vagrant ssh -c 'composer install' While this will update them.

This topic discusses how to set up a connection from your Magento web node to a MySQL server on another host. If you have a separate database host, you must perform the tasks discussed in this topic to install and use the Magento software. (The Magento web node is the server on which you installed the Magento software and that runs your web server.)

This is an advanced topic that should be used only by an experienced network administrator or database administrator. You must have root access to the file system and you must be able to log in to MySQL as root.

Prerequisites

Before you begin, you must:

Install MySQL server on the database server
Create a database instance on the database server
Install the MySQL client on your Magento web node. Consult MySQL documentation for details.

High availability

Use the following guidelines to configure remote database connections if your web server or database server are clustered:

You must configure a connection for each web server node
Typically, you configure a database connection to the database load balancer; however, database clustering can be complex and configuring it is up to you. Magento makes no specific recommendations for database clustering.
For more information, see MySQL documentation.

Resolving connection issues

If you have issues connecting to either host, first ping the other host to make sure it is reachable. You also might need to allow connections from one host to another by modifying firewall and SELinux rules (if you use SELinux).

Create the remote connection

To create a remote connection:

On your database server, as a user with root privileges, open your MySQL configuration file.
To locate it, enter the following command:
The location displays similar to the following:
On Ubuntu 16, the path is typically /etc/mysql/mysql.conf.d/mysqld.cnf.
Search the configuration file for bind-address.
If it exists, change the value as follows.
If it doesn’t exist, add it anywhere except the [mysqld] section.
See MySQL documentation, especially if you have a clustered web server.
Save your changes to the configuration file and exit the text editor.
Restart the MySQL service:
- CentOS: service mysqld restart
- Ubuntu: service mysql restart
If MySQL fails to start, look in syslog for the source of the issue. Resolve the issue using MySQL documentation or another authoritative source.

Grant access to a database user

To enable your web node to connect to the database server, you must grant a web node database user access to the database on the remote server.

This example grants the root database user full access to the database on the remote host.

To grant access to a database user:

Docker Composer Install Ubuntu Debian

Log in to the database server.
Connect to the MySQL database as the root user.
Enter the following command:
For example,
If your web server is clustered, enter the same command on every web server. You must use the same username for every web server.

Docker Compose Install Ubuntu 16

Verify database access

On your web node host, enter the following command to verify the connection works:

If the MySQL monitor displays as follows, the database is ready for the Magento software:

If your web server is clustered, enter the command on each web server host.

Docker Compose Install Ubuntu 20.04

Install the Magento software

When you install the Magento software, you must specify the following:

The Base URL (also referred to as the store address) specifies the hostname or IP address of the web node
Database host is the remote database server IP address (or load balancer if the database server is clustered)
Database username is the local web node database user to which you gave access
Database password is the local web node user’s password
Database name is the name of the database on the remote server
