How to set up remote access to MySQL on Linux

MySQL is a commonly used relational database management system. When developing or deploying applications, we need to set up MySQL remote access settings according to the situation. MySQL remote access settings are particularly important when collaborating on multiple computers or servers.

The default setting of MySQL is to only allow local access. If we need to access MySQL from another computer or server, additional access settings are required.

Below we will introduce in detail how to set up remote access to MySQL on a Linux system.

1. MySQL remote access setting prerequisites

Before setting up MySQL remote access, we need to confirm the following prerequisites:

(3) Confirm the version and port number of MySQL.

(4) Enable remote access to the MySQL server.

(5) Update MySQL user permissions.

(6) Test whether the MySQL remote access settings take effect.

In collaborative development, MySQL remote access settings allow developers to work together on different machines, improving development efficiency and collaboration effects.
