无法使用主目录中的.my.cnf从Node.js客户端连接到MySql

Question

I have the following in my .my.cnf file in my home directory . Actually I will have more entries for other databases too with different suffixes to 'client'. But, for now, to test, I have a simple .my.cnf file as in:

   [client]
   database=db1
   user=user1 
   password=user123
   host=localhost

In my Nodejs program, I use the following connection parameters:

var dbConn  = { 
    user: 'user1',
    database: 'db1'
};

I expect it to connect because the password is in .my.cnf. It does not, gives the following error:

 code: 'ER_ACCESS_DENIED_ERROR',
 errno: 1045,
 sqlMessage: 'Access denied for user \'user1\'@\'localhost\' (using password: NO)',
  sqlState: '28000',

If I put the password in the connection object dbConn, it works. If I run mysql command line without specifying password, I am able to connect by using the password in .my.cnf file.

Wait. You just wrote the .cnf file separately. This wouldn't work. NodeJS wouldn't pick it up automatically. You need to use it with mysql connector. For example:

var ini = require('node-ini');
var mysql= require('mysql');

var config = ini.parseSync('/path/to/your/.my.cnf');

mysql.createPool({
                user: config.user,
                password: config.password,
                database: 'db1'
});
