Allow remote access

If you have iptables enabled and want to connect to the MySQL database from another machine, you must open a port in your server’s firewall (the default port is 3306). You don’t need to do this if the application that uses MySQL is running on the same server.

Run the following command to allow remote access to the mysql server:

sudo ufw enable
sudo ufw allow mysql

Start the MySQL service

After the installation is complete, you can start the database service by running the following command. If the service is already started, a message informs you that the service is already running:

sudo systemctl start mysql

Launch at reboot

To ensure that the database server launches after a reboot, run the following command:

sudo systemctl enable mysql

Configure interfaces

MySQL, by default is no longer bound to ( listening on ) any remotely accessible interfaces. Edit the “bind-address” directive in /etc/mysql/mysql.conf.d/mysqld.cnf:

bind-address		= 127.0.0.1 ( The default. )
bind-address		= XXX.XXX.XXX.XXX ( The ip address of your Public Net interface. )
bind-address		= ZZZ.ZZZ.ZZZ.ZZZ ( The ip address of your Service Net interface. )
bind-address		= 0.0.0.0 ( All ip addresses. )

Restart the mysql service.

sudo systemctl restart mysql

Start the mysql shell

There is more than one way to work with a MySQL server, but this article focuses on the most basic and compatible approach, the

sudo ufw enable
sudo ufw allow mysql

3 shell.

At the command prompt, run the following command to launch the
```
sudo ufw enable
sudo ufw allow mysql
```
3 shell and enter it as the root user:
```
/usr/bin/mysql -u root -p
```
When you’re prompted for a password, enter the one that you set at installation time, or if you haven’t set one, press Enter to submit no password.
The following
```
sudo ufw enable
sudo ufw allow mysql
```
3 shell prompt should appear:
```
mysql>
```

Set the root password

If you logged in by entering a blank password, or if you want to change the root password that you set, you can create or change the password.

For versions earlier than MySQL 5.7, enter the following command in the
```
sudo ufw enable
sudo ufw allow mysql
```
3 shell, replace
```
sudo ufw enable
sudo ufw allow mysql
```
7 with your new password:
```
UPDATE mysql.user SET Password = PASSWORD('password') WHERE User = 'root';
```
For version MySQL 5.7 and later, enter the following command in the
```
sudo ufw enable
sudo ufw allow mysql
```
3 shell, replacing
```
sudo ufw enable
sudo ufw allow mysql
```
7 with your new password:
```
sudo mysql_secure_installation utility
```
0
To make the change take effect, reload the stored user information with the following command:
```
sudo mysql_secure_installation utility
```
1
Note: We’re using all-caps for SQL commands. If you type those commands in lowercase, they’ll work. By convention, the commands are written in all-caps to make them stand out from field names and other data that’s being manipulated.

If you need to reset the root password later, see Reset a MySQL root password.

View users

MySQL stores the user information in its own database. The name of the database is mysql. Inside that database the user information is in a table, a dataset, named user. If you want to see what users are set up in the MySQL user table, run the following command:

sudo mysql_secure_installation utility

2

The following list describes the parts of that command:

SELECT tells MySQL that you are asking for data.
User, Host, authentication_string tells MySQL what fields you want it to look in. Fields are categories for the data in a table. In this case, you are looking for the username, the host associated with the username, and the encrypted password entry.
FROM mysql.user " tells MySQL to get the data from the mysql database and the user table.
A semicolon (;) ends the command.

Note: All SQL queries end in a semicolon. MySQL does not process a query until you type a semicolon.

User hosts

The following example is the output for the preceding query:

sudo mysql_secure_installation utility

3

Users are associated with a host, specifically, the host from which they connect. The root user in this example is defined for localhost, for the IP address of localhost, and the hostname of the server. You usually need to set a user for only one host, the one from which you typically connect.

If you’re running your application on the same computer as the MySQL server, the host that it connects to by default is localhost. Any new users that you create must have localhost in their host field.

If your application connects remotely, the host entry that MySQL looks for is the IP address or DNS hostname of the remote computer (the one from which the client is coming).

Anonymous users

In the example output, one entry has a host value but no username or password. That’s an anonymous user. When a client connects with no username specified, it’s trying to connect as an anonymous user.

You usually don’t want any anonymous users, but some MySQL installations include one by default. If you see one, you should either delete the user (refer to the username with empty quotes, like ' ‘) or set a password for it.

Create a database

There is a difference between a database server and a database, even though those terms are often used interchangeably. MySQL is a database server, meaning it tracks databases and controls access to them. The database stores the data, and it is the database that applications are trying to access when they interact with MySQL.

Some applications create a database as part of their setup process, but others require you to create a database yourself and tell the application about it.

To create a database, log in to the

sudo ufw enable
sudo ufw allow mysql

3 shell and run the following command, replacing

sudo systemctl start mysql

1 with the name of the database that you want to create:

sudo mysql_secure_installation utility

4

After the database is created, you can verify its creation by running a query to list all databases. The following example shows the query and example output:

sudo mysql_secure_installation utility

5

Add a database user

When applications connect to the database using the root user, they usually have more privileges than they need. You can add users that applications can use to connect to the new database. In the following example, a user named demouser is created.

To create a new user, run the following command in the

sudo ufw enable
sudo ufw allow mysql

3 shell:

sudo mysql_secure_installation utility

6

When you make changes to the user table in the mysql database, tell MySQL to read the changes by flushing the privileges, as follows:
```
sudo mysql_secure_installation utility
```
1
Verify that the user was created by running a SELECT query again:
```
sudo mysql_secure_installation utility
```
8

Grant database user permissions

Right after you create a new user, it has no privileges. The user can log in, but can’t be used to make any database changes.

Give the user full permissions for your new database by running the following command:
```
sudo mysql_secure_installation utility
```
9
Flush the privileges to make the change official by running the following command:
```
sudo mysql_secure_installation utility
```
1
To verify that those privileges are set, run the following command:
```
sudo ufw enable
sudo ufw allow mysql
```
1
MySQL returns the commands needed to reproduce that user’s permissions if you were to rebuild the server.
```
sudo systemctl start mysql
```
3 means the users gets no privileges on anything by default. That command is overridden by the second command, which is the grant you ran for the new database.
```
sudo ufw enable
sudo ufw allow mysql
```

Summary

If you’re just creating a database and a user, you are done. The concepts covered here should give you a solid start from which to learn more.
