Cannot connect to mysql server programmatically - javascript

I am trying to connect to a mysql server with the mysql library. I used the following code:
const mysql = require('mysql');
const connection = mysql.createConnection({
host : 'mysql.panamath.org',
user : <username>,
password : <password>,
database : <database>
});
connection.connect(err => {
if (err) return console.log(err);
console.log("Success connecting to database");
});
When I visit mysql.panamath.org, I am redirected to here, where my credentials work fine. However, when I run this connection, I get this error:
Error: ER_ACCESS_DENIED_ERROR: Access denied for user <username>#'129-2-181-10.wireless.umd.edu' (using password: YES)
code: 'ER_ACCESS_DENIED_ERROR',
errno: 1045,
sqlMessage: "Access denied for user <username>#'129-2-181-10.wireless.umd.edu' (using password: YES)",
sqlState: '28000',
fatal: true
It seems to be connecting to '129-2-181-10.wireless.umd.edu'. Interestingly, when I deployed through heroku, it was the same error except it was trying to connect to 'ec2-3-89-96-69.compute-1.amazonaws.com'. I also tried to connect through the terminal:
$ mysql -h mysql.panamath.org -u <username> -p
Enter password:
ERROR 1045 (28000): Access denied for user ...
with the same result.
What's going on here? Why can I connect through the website but not in my code? Is there another module or function for connecting to phpMyAdmin sites, or is the phpMyAdmin site connected to the server somehow?

MySQL cares about where you are connecting from.
Probably username#the-server-hosting-phpmyadmin is allowed to connect while username#129-2-181-10.wireless.umd.edu is not.
Consult the database administrator.

How to connect to remote phpMyAdmin server using NodeJS + ExpressJS

I'm setting up a GraphQL server however I need to connect to a remote phpMyAdmin server which my friend provided and i am getting the error:
Error: getaddrinfo ENOTFOUND 54.193.13.37/phpmyadmin 54.193.13.37/phpmyadmin:3306
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:56:26)
here is the code i use to connect
const mysql = require('mysql');
const db = mysql.createConnection({
host: "54.193.13.37/phpmyadmin",
user: "some_user",
password: "some_password",
database:"some_DB",
})
db.connect((err) => {
if (err) throw err;
console.log("Connected!");
});
I've tried removing "http://", adding port, also the IP address 54.193.13.37 is an IP address for his clan website. So, the only way i have access to the database is by 54.193.13.37/phpmyadmin and i dont have any access to any config files or whatsoever, it's just a remote database that he gave me.
Thanks to whoever can help!
just remove the phpmyadmin in the host. Try host: host: "54.193.13.37".
Phpmyadmin is a web interface, but you want to connect directly to the mysql server wich is normaly on Port 3306.

To connect create-react-app reactJs with mysql

I have problem in connecting my create-react-app with mysql using npm.
Its working in nodejs when i tried seperately without npm. But, When i trying to connect using npm install mysql, It throws me an error...
TypeError: http.IncomingMessage is undefined
./node_modules/express/lib/request.js
Here is my code:
var express = require('express');
var mysql = require('mysql');
var connection =mysql.createConnection({
host: 'localhost',
user: 'user',
password: '',
database: 'reactproject'
});
connection.connect(function(err){
if(!err) {
console.log("Database is connected ... nn");
} else {
console.log("Error connecting database ... nn");
}
});
This will not work from react-app, since react code will run from client side.
You should use my-sql connection in different app and run in different port and call as api connection.
Thanks.
Adding from an #ashik answer is correct, but if you still want to use MySQL and reactjs simultaneously, you can start by creating your own boilerplate, there you can use MySQL on the server side and create APi/web service without having to separate the APi server and client projects reactjs.

ER_NOT_SUPPORTED_AUTH_MODE - MySQL server

Failed at Connecting Node.js Server to MySQL-Database
       
I had MariaDB" installed on a "Node.js Server", but decided that I wanted to use a SQL Database instead. I uninstalled, and completely removed "MariaDB", after which, I proceeded to install the "Community Ed." "MySQL Database". After going through the entire *'MySQL Setup Process'**, I made several attempts to connect to the database via a JavaScript document that implemented the de facto code snippet for a JS DB Connection — my DB-connection document is posted as a code snippet bellow — shown in the code snippet bellow. Disappointingly, the JS/SQL connection failed at each attempt.
Here is the Failed Connection Error Message that I received:
"ER_NOT_SUPPORTED_AUTH_MODE: Client does not support authentication
protocol requested by server. Consider upgrading MariaDB client."
JS/SQL Connection Snippet that I am using:
var mysql = require('mysql');
var connection = mysql.createConnection({
host : 'localhost',
user : 'root',
password : '********',
database : 'foobarDb'
});
For MySQL v8.0 use the following:
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'password'
You need to reconfigure the Quick Action Settings by clicking the "Reconfigure Link" as shown in the screenshot below. From there, select "Legacy password" for v5.1.
The cause of the error:
You installed the latest "MySQL Version", v8.0. The latest version has a different encryption plugin for authenticating users at login. 5.6, and 5.1 revert to the prior encryption algorithms. Please note, 5.6 & 5.1 have several security vulnerabilities reported by oracle.
The top-rated answers in this Q/A thread are for the most part valid, but they are unorganized, which is to say the least. A solution is here, however, the solution is bits and pieces amongst three other answers. To offer an answer that is a single solution, more helpfull, and is a time saver, I'll make an attempt to write an answer myself in a way that is clear, concise, and orderly. I will cover the whole problem that Ubuntu users experiance, and in addition, I will add information that's helpfull, and not included in any other answer, that will help readers understand the issue that persist for them.
To Start: The Issue is not a SQL Problem, it is an Ubuntu Problem
The issue that persist for you, has to do with the fact (a fact most software developers/I.T. professionals are probably all already aware of) the 'ROOT' user doesn't have a password in Ubuntu, and is accessible by anyone with $ sudo privileges. To offer clarity for anyone experiencing this issue who might be new to some of the semantics that I am throwing out there; Ubuntu users use the sudo -i command to register as the Root-user, whereas, every other Linux distribution in existence uses a User-ID w/ a Password. In truth, I cannot remember ever needing to be a ROOT user for anything other than Database Management, and always only when I am first installing a Database to a server, though my experience is probably far limited in comparison to some IT professionals out there. My point is, typically using sudo for everything does the Job, but in this case it is problematic, so the important thing to note is the following:
PROBLEM:
Ubuntu lacks a 'ROOT PASSWORD' and this is why everyone experiencing the issue that we are discussing runs a Distribution of the Ubuntu OS/SHELL. And unless we rewrite the Ubuntu kernel, and the practically everything else in the operating system, we cannot give Ubuntu SHELL a "root password".
SOLUTION:
We may not be able to give the Ubuntu SHELL a root password, but we can, and we will, give MySQL a 'ROOT PASSWORD'.
TO EXECUTE THE SOLUTION YOU NEED TO HAVE THE FOLLOWING:
Node.js v12+
NPM (Probably need v5+ but don't quote me on that)
MySQL v8.0+ (obviously)
The MySQL Driver (from npm)
CONFIRMATION:
If you don't already have everything on the list you honestly can't say that this is the issue your dealing with.
If you do have everything on the list
and you are running an Ubuntu distro, then you should be getting an error message that probably looks somthing like the one I got when I had to fix this issue.
My error message read:
ERROR: (28000): Access denied for user 'ajc'#'localhost'
ERROR: ERROR_NOT_SUPPORTED_AUTH_MODE: Client does not support
authentication protocol requested by server; consider upgrading
MySQL client
'Client does not support authentication protocol requested by server; consider upgrading MySQL client
If your still reading then your likely in the right place.
To start fixing the problem create an empty Node.js project, and install the MySQL driver as a dependency to it using NPM (you should know how to do this, as you had to do that to have this issue). Add a JavaScript .js file. Call the file, sqltest.js or whatever something like that.
Add the code below to the file you just created.
let mysql = require('mysql');
let connection = mysql.createConnection({
host : 'localhost',
user : 'root',
password : '********',
database : 'DB_App_00',
});
connection.connect(function(err) {
if (err) {
return console.error('error: ' + err.message);
}
console.log('Connected to the MySQL server.');
});
In the method called 'createConnection' is a JSON OBJ parameter holding the credential values to make a valid connection to the MySQL database server. The user has to equal to 'root', and the database has to exist. Also for a later test add a testing table to the database, with some BS data."
Now open a terminal window, and do your typical updates & upgrades, this is important, which is why every tutorial asks you to do them.
~$: sudo apt update
~$: sudo apt upgrade
After you do your upgrades enter the following command into your terminal:
~$: sudo mysql -u root
It should prompt you for your Ubuntu Password, type it and [ENTER].
The next step is critically important:
Now here is the step that could be considered the medicine and/or the cure to the problem. Your terminal should be open, and you should be inside of the MYSQL Server, under the user 'root'. The terminal should have the cursor flashing at a blank mysql command-line. Within the CMDL copy & paste this:
mysql> ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'ChoosePassword';
mysql> FLUSH PRIVILEGES;
The next part is obvious, change 'ChoosePassword' to a password you will remember while leaving the password within single quotation marks. Change absolutely nothing else, press [ENTER]
If you followed the steps correctly, you now have a MySQL 'ROOT USER' with its own password now. Test it by copy and paste the following at the Ubuntu CMDL:
~$: mysql -u root -p
It will prompt you for your new password, type it and [ENTER]
...you should be in, now exit.
mysql>exit
Back to your 'testsql.js' file, alter the credentials to root for the user, password to your password, a valid database, and host to localhost, unless you have a unique need for a different hostname.
let connection = mysql.createConnection({
host : 'localhost',
user : 'root',
password : '********',
database : 'DB_App_00',
});
now use node to run the node test file
~$: node testsql.js
Final Thought:
If it doesn't say connected you did something wrong, but if all went well, you should connect. It took some effort before I got it to work, but this answer should save you some time from reading all the other half written answers.
You can use the package mysql2 instead of mysql. I ran into the same issue and using mysql2 worked for me.
You can install this package using npm i mysql2
You can either alter an existing user to use mysql_native_password, or create a new user,
CREATE USER 'new_user'#'%' IDENTIFIED WITH mysql_native_password BY '***';
GRANT USAGE ON *.* TO 'new_user'#'%';
ALTER USER 'new_user'#'%' REQUIRE NONE WITH MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0;
GRANT ALL PRIVILEGES ON `new_user`.* TO 'new_user'#'%';
FLUSH PRIVILEGES;
replace new_user with your new user name, and set your password.
Now you can access mysql from node using the mysql package,
npm install mysql
recommended to use pool connection for this package.
I figure that some MySQL versions have the authentication for the establishment of a connection a bit messed up. All I had to do was add the line "insecureAuth" : true to the CreateConnection(...) credentials.
var connection = mysql.createConnection({
host : 'localhost',
user : 'root',
password : '********',
database : 'vod_bill_database',
insecureAuth : true
});
The error is gone now, and the client is successfully connecting.
1st run this code ->
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
2nd
flush privileges;
try the older version of mysql like 5.6.40, it uses by default SHA256_password auth where new version 8.0. uses by default sha2_password auth which is more secure and throw this authentication protocol error.
MYSQL installer 5.6.40
yellow yow bros !
// mysql.ts
const pool = mysql.createPool({
connectionLimit: 10,
host: "localhost",
user: "root",
password: "password",
database: "rest-resume-api",
});
and then I have a docker-compose file such as
# docker-compose.yml
version: '3.3'
services:
db:
image: mysql
restart: always
command: --default-authentication-plugin=mysql_native_password
environment:
MYSQL_DATABASE: 'rest-resume-api'
MYSQL_USER: 'root'
MYSQL_ROOT_PASSWORD: 'password'
ports:
- '3306:3306'
expose:
- '3306'
volumes:
- my-db:/var/lib/mysql2
volumes:
my-db:
you can do it
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'password'
ALTER USER 'root'#'%' IDENTIFIED WITH mysql_native_password BY 'password'
FLUSH PRIVILEGES;
check mysql root user IDENTIFIED
select user,host,plugin from user;
+------------------+-----------+-----------------------+
| user | host | plugin |
+------------------+-----------+-----------------------+
| root | % | mysql_native_password |
| mysql.infoschema | localhost | caching_sha2_password |
| mysql.session | localhost | caching_sha2_password |
| mysql.sys | localhost | caching_sha2_password |
| root | localhost | mysql_native_password |
+------------------+-----------+-----------------------+
var connection = mysql.createConnection({
host : 'localhost',
user : 'root',
password : '********',
database : 'vod_bill_database',
port : 3308
});
I had the same error and since i changed my port in phpmyadmin from 3306 to 3308 therefore here also i had to write port: 3308 and it started working.
in order to overcome this error use the following code:
var connectionString = 'mysql://*root:*password#*localhost/*database?charset=utf8_general_ci&timezone=-0700';
var connection= mysql.createConnection(connectionString);
but make sure that you changed the * marks in the connectionString based on your setup.
just create a new user on MySQL
CREATE USER 'foo'#'localhost' IDENTIFIED WITH mysql_native_password BY 'bar';

PostgreSQL keep failing password auth in Node.js

Seems like There's something wrong with connect function.
config.DATABASE_URL is initialized using environment export DATABASE_URL=postgres://bustabit:1234#localhost/bustabitdb
function connect(callback) {
return pg.connect(config.DATABASE_URL, callback);
}
error: password authentication failed for user "bustabit"
at Connection.parseE (/home/bobbysun/busta/bustabit-gameserver/node_modules/pg/lib/connection.js:526:11)
It's kind of weird that It fails just like in connect function when I try to login psql in shell like:
psql -d bustabitdb -U bustabit
psql: FATAL: Peer authentication failed for user "bustabit"
but This one works:
psql bustabit -h 127.0.0.1 -d bustabitdb
Password for user bustabit:
psql (9.3.16)bustabitdb=>
Does anybody have any idea why this happens? I think I should change DATABASE_URL but I'm pretty new to postgreSQL so I have no idea what to change.
UPDATE: upgrading pg module to latest version resolves this problem.

How do I allow the node pg module communicate with my Windows postgresql server?

I have a node server on localhost. In it is the pg module:
//above is express requires
var pg = require('pg');
var client = new pg.Client();
client.connect((err)=>{
if(err) throw err;
client.end((err)=>{
if(err) throw err;
});
})
//below is basic express server stuff
I have, I believe, a postgresql server running on windows. I have pgadmin open, there is a localhost:5432 section, and inside is a "test" database I have created.
My node server currently throws:
error: password authentication fails for user 'myname'
I do not understand how I can, either in postgresql's Windows client, set default username/password that is then added to environment variables, or, in Windows add the proper environment variable key/value pairs that the node pg module expects so it can login, or, tell the node pg module how to login to postgresql, or, whether I am even going down the right path at all.
How can I allow my node pg module to connect to my localhost postgresql server?
EDIT: I tried to follow the instructions in this SO answer, however I would always recieve "access denied" errors no matter where I pointed the db creation to, whether I used cmd or powershell in admin or no, and no matter the permissions I set for files. I'm now primarily interacting with postgresql through the pgadmin III GUI.
EDIT2: I tried modifying the pg initialization by doing:
var connectstring = 'postgres://me:password#localhost/dbname';
var client = new pg.Client(connectstring);
I received the same error, using the same exact login details I was prompted with by pgadmin III.
EDIT3: According to these docs, I should possibly have that list of environment variables? If not, where can I find this information so I can manually set these environment variables? Is this the right path to go down?
Use:
var pg = require('pg');
var config = {
user: 'foo',
database: 'my_db',
password: 'secret',
port: 5432
};
var pool = new pg.Pool(config);
