here , -u flags specifies User Name and -p flags specifies Password.
After entering password , We can see below welcome message,
Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 90 Server version: 8.0.19 MySQL Community Server - GPL Copyright (c) 2000, 2020, Oracle and/or its affiliates. All rights reserved.

Type '\c' to clear the current input statement.
Step 5: Create MySQL Remote User
First, Login to MySQL Server with root user using command line, Login to MySQL using username root and password
mysql -u root -p
Below is command is to create user , here i am creating user “fosstechnix“.
mysql> CREATE USER 'fosstechnix'@'%' IDENTIFIED BY 'fosstechnix@123';
Next, assign the privileges to database with below command , here i am assigning all databases privileges to user fosstechnix, If you want to assign privileges to specific database replace ” .” with database name.
mysql> GRANT ALL PRIVILEGES ON * . * TO 'fosstechnix'@'%';
OR If you want to allow “fosstechnix” user to give privileges to other user.
mysql> GRANT ALL PRIVILEGES ON *.* TO 'fosstechnix'@'%' WITH GRANT OPTION;
To take effect reload the privileges using below command,
mysql> FLUSH PRIVILEGES;
Step 6: Enable MySQL Remote Access
By default, In MySQL database server remote access is disabled for security reason. To enable remote connections of MySQL Server, we have to change bind-address in MySQL configuration file. Open the /etc/mysql/mysql.conf.d/mysqld.cnf file
sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf
Below the [mysqld] section find the Line,
[mysqld] bind-address = 127.0.0.1
And replace it to
bind-address = 0.0.0.0
Restart the MySQL Server to take effect.
sudo systemctl restart mysql.service
To Enable MySQL 8 on System startup.
sudo systemctl enable mysql.service
Step 7: Start,Stop,Restart and Status of MySQL Service
To start MySQL Service
sudo systemctl start mysql.service
To stop MySQL Service
sudo systemctl stop mysql.service
To restart of MySQL Service
sudo systemctl restart mysql.service
To check status of MySQL Service
sudo systemctl status mysql.service
