Type 'help;' or '\h' for help. 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
