It is worth mentioning that we will not see good practices of databases, relationships, etc. We will use the tables as they are, without looking at normalization, or things like that.

Note: this tutorial uses PDO, but remember that we can also use mysqli functions. Personally I recommend PDO, because it is object oriented. However, I hope to write a tutorial about mysqli in the future.

How to install MySQL (MariaDB) on Android with Termux

Install MySQL on Android

Android mobile devices are not designed to be servers (although some of them are powerful), however it is always interesting to see how technology advances and day by day we can do more things with our phones.

Today we will see how to install the MySQL or MariaDB server on Android, thanks to the Termux application. For that it is enough to execute a few simple commands and voila, we will have a MySQL database server in our Android; fully functional and ready to execute queries.

If we want to put it for production, we can do it as long as we configure security. In short, we will not see more advanced topics; we will only see how to install mysql on Android.

Here we will use MariaDB and MySQL as synonyms; that is, if you see that I say MariaDB do not get confused, I mean MySQL; and vice versa.

I know that there are really more differences especially with the licenses, but that is another topic and you can search it in Google if you wish.
