When working with MySQL, it can be very difficult to visualize an entire database of information, especially if there are relational databases that all work in tandem to present data. Fortunately for us, there are numerous GUI based applications that can be downloaded and installed on a Linux system that make the process of managing databases much easier. Many users prefer interacting with MySQL through a GUI rather than a command line, where it is difficult to visualize multiple columns of data and understanding how they correspond to each other.
Apache, MySQL, and Python can be used in tandem to host and serve a website from a Linux system. This assortment of software is known as a LAMP stack (Linux, Apache, MySQL, Python) although sometimes the ‘P’ means PHP, which can either be used in addition to or as a replacement of Python. Apache serves the website, MySQL stores and retrieves information from a database, and Python can generate HTML and related code for the site’s visitors to view.
MySQL server has gone away error can occur when you have an established connection to the MySQL server and for one reason or another, the connection times out or otherwise goes down. In the context of a Linux system, the error can sometimes be seen from the MySQL client. In this tutorial, we will show several solutions for dealing with and troubleshooting the MySQL error.
If you wish to access your MySQL server remotely, it will be necessary to configure one or more users to allow access from remote hosts. If you do not know all the IP addresses of the connecting hosts, then you can simply allow connections from all hosts.
If you need to allow remote access to your MySQL server, a good security practice is to only allow access from one or more specific IP addresses. This way, you are not needlessly exposing an attack vector to the entire internet.
MySQL is probably the most famous Relational Database Management System (RDBMS). Developed as a free and open source software, it was originally backed by the MYSQL AB company, but is now owned by Oracle. In MySQL the “storage engine” used for a table determines how data is handled.
A LAMP stack is an assortment of software that contains everything you need in order to serve a website, show dynamic content, and store or retrieve data from a database. The software is all within the LAMP acronym, namely the Linux operating system, Apache web server, MySQL database (or MariaDB alternatively), and PHP programming language.
