Procedures

Step 1. Prerequisites

Well, to deploy MySQL on a Linux server, you should have a Linux server first. ~~Of course.~~

Step 2. Install MySQL

Just execute a ordinary install command.

1	sudo apt install mysql-server

Then, you can check the installation.

1	mysql --version

And you can check the status of MySQL service. If not started, execute the command below and check again.

1 2	systemctl status mysql.service sudo systemctl start mysql # only use this when the previous fails

Step 2. Set Root Password

After installation, we should reset our root password. First, enter MySQL.

1	sudo mysql -u root

Notice that, we have to use sudo at the first time. Since it requires some extra privileges.

Then, we can change root password by the following SQL. Just replace 123456 with your favorite password. 🤪

1	ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password by '123456';

Here, root can only access database from localhost. If we want to access it remotely, we can create a new user, and grant it all privileges.

1
2
3

CREATE USER 'admin'@'%' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'%';
FLUSH PRIVILEGES;	# if you want to make sure privileges are applied

Step 4. Change Configuration

I’m not sure if this is needed, but I guess its somewhat useful. Just comment bind-address = 127.0.0.1 out, or change it to 0.0.0.0.

1	vim /etc/mysql/mysql.conf.d/mysqld.cnf

Then, restart MySQL service.

1	sudo service mysql restart

Step 3. Allow Access

Emm… One last step. Make sure the 3306 port is open. This can be found in the control panel of your server’s provider.

Now, we can use admin to connect to our server remotely.

Step 4. Connect MySQL with Navicat

In Navicat, crate a new connection. And just fill it with the host, username and password. And you are good to go.

Well, this is it. Too late… go to bed! 😴
