如何在Android手机上安装MySQL以与Node.js一起使用

Question

Are there any MySQL lightweight apps that can be installed on mobile android phone preferably in the background process?

I followed this tutorial Building a Node.js application on Android I'm able to run non-SQL node server scripts but I rely on MySQL instances to have a connection on localhost using node.js mysql module.

var mysql      = require('mysql');
var connection = mysql.createConnection({
  host     : 'localhost',
  user     : 'root',
  password : 'root',
  database : 'database'
});
connection.connect();

Is there anyway I could create an MySQL instance on android actually?

I'd recommend using sqlite3 , because it uses a small file as it's database. It has a much smaller footprint than alternatives like mysql and postgres. Store it in the install directory of the node app and connect to it via a library like knex.js or sqlite3 .

Example using knex.js (my preference):

var knex = require('knex')({
  client: 'sqlite3',
  connection: {
    filename: "./mydb.sqlite"
  }
});
