How to install MySQL on Ubuntu

Database management can become a really complex task due to the amount, type and complexity of this data, but there are platforms that help us mitigate this impact and have a centralized administration of the data and one of the most popular is MySQL..

 

MySQL has been created as a SQL (Structured Query Language) database server where its speed, multithreading capabilities, and multiuser stand out. It has been designed for production systems where data of all kinds abounds and it is capable of being integrated into software that they make use of the mass deployment method.

 

MySQL Features
Some of the general features of MySQL are:

 

  • Your database is relational
  • Is free
  • Allows you to use CMake to make it a portable option
  • It supports data like FLOAT, DOUBLE, CHAR, VARCHAR, BINARY, VARBINARY, TEXT, BLOB, DATE, TIME, DATETIME, TIMESTAMP, YEAR, SET, ENUM and many more.
  • It has independent modules to increase the actions of use
  • Makes use of B-tree disk tables (MyISAM) with index compression

 

 

 

MySQL Advantages
Currently MySQL is available in version 8.0 which offers:

 

  • Added a data dictionary
  • Integration of atomic data definition statements (atomic DDL)
  • Improved update process
  • session reuse
  • Enhanced security and account management
  • The grant tables in the MySQL system database will be converted to InnoDB or also called transactional tables.
  • Added a new authentication plugin caching_sha2_password
  • The caching_sha2_password and sha256_password authentication plugins have stronger password encryption than mysql_native_password
  • Optimized resource management
  • Table encryption management
  • InnoDB improvements
  • Support of new characters
  • JSON improvements
  • MySQL now supports windowing functions
  • Regular expression support
  • Time zone support for TIMESTAMP and DATETIME

8

 

step 10

We start the service if necessary:
 sudo systemctl start mysql.service 
step 11

We enable the service at Ubuntu boot:
 sudo systemctl enable mysql.service 

9

 

step 12

We access MySQL:
 sudo mysql 
image

 

 

step 13

We set the root password:
 ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'PASSWORD'; 
image

 

step 14

We leave the console:
 exit; 
image

 

step 15

We ensure the installation of MySQL since by default it presents some security flaws, for this we execute:
 sudo mysql_secure_installation 
image

 

step 16

We enter the root password in the initial part we enter the letter "n" so as not to change the root password:

step 17

Then we enter in all the fields the letter "y":

 

image

 

step 18

We access MySQL with the password:
 mysql -u root -p 
image

 

step 19

We create the database with the syntax:
 CREATE DATABASE(base); 
image

 

step 20

We create the user with password:
 CREATE USER 'user'@'localhost' IDENTIFIED BY 'password'; 
image

 

step 21

We assign the database permissions to that user:
 GRANT ALL PRIVILEGES ON base.* TO 'user'@'localhost'; 
step 22

We leave the console with exit;.

Step 23

We log in to MySQL again either with the root user or with the created user and validate the available databases:
 show databases; 
step 24

There we can see the database that we have created.

step 25

Update the system:
 sudo apt update 
image

 

Step 26

To install extra utilities, as optional, we execute:
 sudo apt install mysql-workbench-community libmysqlclient18

Step 27

Finally to see the version of MySQL we execute the command:
 mysql -V 
image

 

We see how MySQL can be installed in a simple and functional way in Ubuntu and with it have one of the best platforms to manage data which is not only free but as we saw full of functions that make it the ideal solution for this type of work.
