Introduction to MySQL Administration
MySQL Administration is defined as a program or operation that is used to perform administrative tasks like configuring, monitoring, managing users, and its role, starting and stopping MySQL server with backups and other such admin procedures. The MySQL Administration is intended to work with MySQL 4.0 versions and higher than it also. MySQL Administration guides you on how to start, halt, and resume a MySQL Server on Windows and Linux. MySQL is an open-source RDBMS software under GNU licensed and popularly used with PHP programming and other web applications. MySQL is a Database Management System that works on a server that is fast, secure, and easy to use for both small or huge data application storage and access. MySQL server can accumulate a huge amount of bulky data in the arrangement of MySQL tables which are in the form of related rows and columns. To fetch and manage MySQL data, MySQL Administration uses a standard query language called SQL – Structured Query Language, which plays an important role in manipulating the records or rows of tables in the server. Also, the SQL query helps in organizing all the databases to maintain the server and its data privacy.
Why do we need MySQL Administration?
MySQL Administration works for running different operations and assigning users privileges to work for the database server management activities so that the MySQL is maintained and secured. MySQL administration offers many tools which help to serve for server maintenance, server configuration, database backup, Security, user roles, initialize/shutdown, duplication supervision, repair, restore, resource managing, performance check, status report, access records, CRUD operations SQL, granting permissions, etc. Thus, MySQL Administration is an admin level responsibility to handle all the tasks executing on a server to make things run properly and ensures data integrity, security and fast management to allow users to interact in a better way.
How does MySQL Administration work?
We can install WAMP or XAMPP MySQL servers to use PHPMyAdmin i.e. admin panel of MySQL. PHPMyAdmin is dedicated to handling the administration of MySQL over the web applications which is free software written in PHP.
You can even download MySQL Database from www.mysql.com. You can see the below WAMP localhost page and PHPMyAdmin page:
On clicking PHPMyAdmin, we need to use login credentials but by default here, the root is username and password is blank:

Showing all databases:
MySQL Administration bench allows us to integrate the tools into a simpler and friendly graphical user interface. MySQL DBA enables us to create and manage databases. Using MySQL Commands, we can achieve managing the databases and their records successfully.
We have some commands described below:
- Show Databases: Lists all the databases present in the MySQL Server.
- Show Tables: Displays all the tables stored in a particular MySQL database.
- Show Columns: Shows the list of columns from a specific table in the database server.
- Show Processlist: Finds the currently running processes or threads in the MySQL server.
With these features, DBA also provides some special tools as follows:

- Backup: Using the mysqldump tool, you can take a backup of one or multiple databases.
- Restore: Even, you can restore the database with the dump file.
- Maintain Tables: Responsible to provide commands to preserve the databases in the MySQL server.
Roles of MySQL Administration
MySQL Administration provides the following roles:
- Create Users: It defines how to add new users in the MySQL Server.
- Grant Privileges: It permits rights to the user.
- Revoke Privileges: It withdraws the user privileges from the account.
- Manage Roles: It organizes the different roles assigned to the users and their privileges.
- Show Granted Privileges: Presentation of rights associated with the user roles or their respective accounts in the server.
- Drop Users: It defines to know how to remove or delete a user.
- Change passwords: helps to learn how to set passwords for the MySQL server users.
- Show Users: Explains how to display user accounts in the server.
- Rename Users: Allows to rename a user to another.
- Lock User Accounts: Describes how to lock the MySQL server users or their respective accounts.
- Unlock User Accounts: Defines how to unlock the MySQL user accounts.
Therefore, MySQL administration activities help to retrieve and manage the data. It provides different features to execute many tools to organize the MySQL server. Mostly, the tasks can be implemented by using a command-line client like MySQL or MySQLAdmin.
Remember in MySQL Administration, you will find the user details that exist in a MySQL named database and tables by the name user. Though the main privileges exist in the user table itself you can get the user privileges in different tables based on the privilege level of different databases. We need admin user privilege to access the MySQL server by MySQL Administration roles.
Advantages of MySQL Administration
Let us see some advantages below:
- MySQL Administration displays an improved structure or summary of the settings which are vital for the performance of MySQL Server. Hence, it helps to show this by graphical representation which helps to make the reading and indication of the tune settings of the MySQL Server.
- Defines rules to create a new user, give rights to access user account, cancel user rights, organize user roles, and administrative activities in the database server.
- It determines the security risk management, maintains user accounts, their passwords, drop the user, and also lock or unlock them whenever needed.
- It defines high performance with scalability, continuous uptime, secure transactional support, provides open-source flexibility, and cost-effectiveness for ownership.
- MySQL administration includes controlled workflow and stored procedures.
- We work with SQL queries with a standard and very popular easy to use friendly language to interact with the records manipulation and access.
- It gives us functionality to easily import and export data files from the server but it depends upon the limited file size.
Conclusion
MySQL Administration applies on MySQL server which is a relational database that relates all data with some conditions and can be retrieved using SQL. This admin process helps for a wide range of purposes such as Data Warehousing, E-commerce, logging applications, Web applications, and stores a huge amount of data of all fields like IT, Medical, Government, Business, Education, etc. Thus, MySQL Administration is easy to interact like with web-based administrative tool PHPMyAdmin or admirer and begin to learn with basic knowledge of SQL
