MySQL 8 Administrator???s Guide

Installing and Upgrading MySQL 8

In the previous chapter, we provided an overview of MySQL along with MySQL 8's new features, use cases, and limitations. MySQL is very flexible in terms of platforms, such as RedHat, Fedora, Ubuntu, Debian, Solaris, Microsoft Windows, and so on. It has the support of an API to connect with different languages, such as C, C++, C#, PHP, Java, Ruby, and many more. For any programming platform, the most important and monotonous task is to set up the environment with the necessary software tools. That won't be the case for MySQL 8, as this chapter is focused on setting up the environment with MySQL 8.

This chapter explains MySQL 8's installation steps in detail with the necessary prerequisites. Separate installation steps are provided to set up MySQL 8 on various platforms. The chapter also covers methods to upgrade to or downgrade from...

The MySQL 8 installation process

This section will guide readers in MySQL 8 version selection, where to get MySQL 8 from, and how to install MySQL 8. It also explains the post-installation steps required for setup. This chapter provides information on how to upgrade or downgrade from MySQL 8.

General installation guide

MySQL 8 is available on many operating systems with different versions. The MySQL 8 release is managed in two ways:

  • Development release: This has the newest feature but is not recommended for use in production
  • General release: This is a stable release and users can use it for release in production also

Naming conventions are followed in each release of MySQL 8, which indicates its status. Each release name...

Post-installation setup for MySQL 8

Post-installation is a process that describes the basic steps or configuration that the user has to perform after MySQL 8 installation.

Data directory initialization

In previous sections, we have seen different methods of MySQL 8 installation. Some of the methods will automatically create a data directory for MySQL 8. For generic binary distribution and source distribution, data directory creation is a must. Data directory initialization is performed by either of the following two commands:

E:\> bin\mysqld –-initialize 
E:\> bin\mysqld --initialize-insecure

Either of these commands can be chosen based on the user's requirements to generate a random initial password or not...

Upgrading MySQL 8

In previous versions of MySQL, the data dictionary is stored in the file-based system while in MySQL 8 it is stored in the data dictionary structure. So, the up-gradation process will move the file-based structure into the data dictionary structure. Up-gradation into MySQL 8 is possible from the MYSQL 5.7 GA version, which means from 5.7.9 or higher. For non-GA versions of 5.7, up-gradation is not possible. Before starting the up-gradation process, the following points need to be understood.

Upgrading methods

Two methods are in use for up-gradation that are differentiated by their implementation method. Let us discuss these methods in detail.

...

MySQL 8 downgrading

Downgrading is the reverse process of up-gradation, where we will move from a higher version of MySQL to a lower version of MySQL. In this section, we cover how to downgrade from MySQL 8 to MySQL 5.7. A downgrade that does not support a version skip means that downgrading from MySQL 8 to MySQL 5.6 is not supported. Within the same series where a version skip is supported means you can downgrade from MySQL 8.z to MySQL 8.x by skipping the MySQL 8.y version. First, we will explain some basic points that need to be understood before starting downgrading.

Downgrading methods

An in-place downgrade means shutting down the new version of MySQL 8, replacing its binaries or packages with the old version of MySQL...

Summary

To choose the proper software with its version for development is an important phase, right? In this chapter, we understood how to select the proper version of MySQL 8 by understanding its version pattern. We also learned the execution steps of MySQL 8 installation using the installer and command line in Microsoft Windows. For the Linux platform, we installed MySQL 8 using the Yum repository, RPM package, and Debian package. Post-installation describes the basic configuration to start with MySQL 8. Finally, we explained how to upgrade and downgrade from MySQL 8 with execution steps.

In the next chapter, we will learn about various programs and utilities available for MySQL 8. It mainly focuses on how to use these programs for MySQL 8 along with command-line executions.

I like the book and will likely purchase their advanced Mysql 8 book. I hope they have improved editing in it.They need to have a human edit the text. There are many grammatical errors in the text. The missing articles, loose for lose, than for then, and many other such items are distracting. In the worst case these errors obscure the meaning of the text. I am not a grammar expert but this carelessness is a problem.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
