hi I am developing an application in nodejs which uses orientdb.
I am using orientjs version 2.2.10
var OrientDB = require('orientjs');
var server = OrientDB({
host: '127.0.0.1',
port: 2424,
username: 'root',
password: '123',
servers: [{
host: "192.168.0.159",
port: 2425
}],
});
server.connect().then(() => {
console.log("connected");
}).catch(err => {
console.log(err);
})
above is a simple code to check whether the driver connects to the server. however when there is no orientdb instance running in localhost i get the connection refused error. it looks like that when connecting it first tries host in main object and never tries to connect to hosts in servers array. I have also tried orientjs v3, result is the same.
can someone tell me what could be the issue here?
thanks
You can try like this:
databaseConfig = {
"host": '127.0.0.1',
"port": 2424,
"username": 'root',
"password": 132,
"name": 'databaseName',
"user": 'root'
};
let server = OrientDB(databaseConfig);
let db = server.use(databaseConfig);
db.open()
.then(()=>{
console.log('Connected!')
});

I have a connection on DBeaver using an ssh tunnel as follows:
sshHostname;
sshPort;
sshUser;
sshPassword;
on the actual connection to the database I have:
dbHost;
dbPort;
dbName;
dbUsername;
dbPassword;
my node js code looks something like this:
const { Pool, Client } = require('pg')
const ssh2 = require('ssh2');
const dbServer = {
host: dbHost,
port: dbPort,
database: dbName,
username: dbUser,
password: dbPassword
}
var c = new ssh2();
c.connect({
host: sshHostname,
port: 22,
username: sshUser,
password: sshPassword
});
c.on('ready', function () {
c.forwardOut(sshHostname, '22', dbHost, dbPort , function(err, data) {
const client = new Client({
host: 'localhost',
port: dbPort,
database: dbName,
user: dbUser,
password: dbPassword,
})
client.connect(function (err) {
if (err) {console.log(err)}
else {console.log('connected...')}
});
client.end();
})
});
I get the following error:
Error: connect ECONNREFUSED 127.0.0.1:dbPort
at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1133:16) {
errno: -4078,
code: 'ECONNREFUSED',
syscall: 'connect',
address: '127.0.0.1',
port: dbPort
}
I tried various configurations and various libraries with no success.
do you have any idea how to connect via nodejs to a database over a tunnel?
I have a feeling that I am actually not connecting to the ssh tunnel.
It could various of reasons why there is a connection refusion.
When making connections via SSH, you should have a SSH key ready on your computer and make it a part of your SSH white list. This is a common error many developers may run into, but since your critical information is hidden, we may need you to provide more details in that regard.
When connecting to the database with sequelize-typescript, an error occurs

I tried connectit with and without a port, the error is the same. It just connects to SERVER, but does not want to connect to the named SERVER \ SQL2016. How can I fix this error? Found nothing on the docks
ENOTFOUND is an operating-system-level error from your OS's networking code. It means you asked it to look up a hostname and it came up with nothing. In the lingo, your name "could not be resolved." (www.stackoverflow.com is a hostname, for example. https://www.stackoverflow.com is a URL, which happens to contain a hostname.)
getaddrinfo() is OS method that asks the domain name service (DNS) to look up a hostname.
It looks to me like you tried to look up the hostname SERVER\SQL2016. That's not a hostname. You probably want something like sql2016.example.com instead. Ask the person who operates that SQL Server instance for the correct hosthame.
The SQL Server instance I use has a hostname something like devdatabase.dev.example.com.
Edit The SQL2016 part of your connection string is known as the server instance or DataSource. You need to specify it separately from the hostname. See this. Error connecting to SQL Server database with sequelize You also need to make sure your SQL Server software is configured to allow TCP connections.
Try this as you connect.
export default new Sequelize({
database: environment.database.database,
dialect: "mssql",
username: environment.database.username,
// port: environment.database.port,
password: environment.database.password,
host: environment.database.host, /* should be the hostname without \SQL2016 */
logging: !environment.production ? console.log : false,
models: [normalize(join(__dirname, "..", "models"))],
dialectOptions: {
instanceName: 'SQL2016',
options: {
enableArithAbort: true,
cryptoCredentialsDetails: {
minVersion: "TLSv1",
},
},
},
})
I changed the default port 1433 on my SQL Server in centos 7. But in API that is created with Node.js and uses the mssql package to connect to it, I get the error shown here when I want to send or get a request. mssql knows 1433 port as default.
My connection string
var sql = require('mssql');
var DbConnectionString = {
user: 'sa',
password: 'mypassword',
server: 'serverip,newport',
database: 'databasename',
"options": {
"encrypt": false,
"enableArithAbort": true
},
};
module.exports = DbConnectionString;
And this is the error I get:
{
"code": "ESOCKET",
"originalError": {
"message": "Failed to connect to myserverip,mynewport:1433 - getaddrinfo ENOTFOUND myserverip,mynewport",
"code": "ESOCKET"
},
"name": "ConnectionError"
}
How to solve it?
The mssql docs state that port can be specified with the 'port' key:
var DbConnectionString = {
user: 'sa',
password: 'mypassword',
server: 'serverip',
port: newport,
database: 'databasename',
"options": {
"encrypt": false,
"enableArithAbort": true
},
};
EDIT: I found a file at /config/database.js which is used to connect to sqlite in development. When I change the client name from sqlite to postgres, that's when the trouble starts.
Isn't strapi supposed to ignore files like this in production? How can I get strapi to ignore this file, and just use my postgres db?
module.exports = ({ env }) => ({
defaultConnection: 'default',
connections: {
default: {
connector: 'bookshelf',
settings: {
client: 'sqlite',
filename: env('DATABASE_FILENAME', '.tmp/data.db'),
},
options: {
useNullAsDefault: true,
},
},
},
});
End edit.
I'm trying to get my strapi app to start up in production, but it keeps erroring out saying
[2020-07-22T01:15:40.246Z] debug ⛔️ Server wasn't able to start properly.
[2020-07-22T01:15:40.247Z] error error: password authentication failed for user "<redacted>"
The rest of the output is related to pg, which leads me to think that this is a DB connection error.
I can log into my db from the command line using psql -U postgres -W, which confirms that I know my password.
In addition, I'm using pm2 to run things, and instead of using process.env in that file, I just added the db variables directly, but that made no difference.
The application has been built in production mode. I have 3 dbs in pg, one called postgres, one with my apps name, and another called strapi.
Thanks
my /config/enviroronments/production.database.json looks like this
{
"defaultConnection": "default",
"connections": {
"default": {
"connector": "bookshelf",
"settings": {
"client": "postgres",
"host": "${process.env.DATABASE_HOST || '127.0.0.1'}",
"port": "${process.env.DATABASE_PORT || 27017}",
"database": "${process.env.DATABASE_NAME || 'strapi'}",
"username": "${process.env.DATABASE_USERNAME || ''}",
"password": "${process.env.DATABASE_PASSWORD || ''}"
},
"options": {
"ssl": false
}
}
}
}
and I have a .env file at the root of the backend app that looks like this
DATABASE_HOST=localhost
DATABASE_PORT=5432
DATABASE_NAME="<redacted - all letters>"
DATABASE_USERNAME="<redacted - all letters>"
DATABASE_PASSWORD="<redacted - all letters>"
Found the issue. When I created the app, I used sqlite as my db. As a result, the default database.js file wasn't set up in a way that could be overwritten with env variables.
I created a new local Strapi app with pgsql as my db, and copied the contents of the database.js file to my server. All working now.
New file for reference
module.exports = ({ env }) => ({
defaultConnection: 'default',
connections: {
default: {
connector: 'bookshelf',
settings: {
client: 'postgres',
host: env('DATABASE_HOST', '127.0.0.1'),
port: env.int('DATABASE_PORT', 5432),
database: env('DATABASE_NAME', 'my-strapi-project'),
username: env('DATABASE_USERNAME', 'testing'),
password: env('DATABASE_PASSWORD', 'testing'),
ssl: env.bool('DATABASE_SSL', false),
},
options: {}
},
},
});
I had the same situation in development. I created a strapi app with SQLite and decided to use PostgreSQL. That's where the trouble came in. So the fix was as follows:
app_name/config/database.js
module.exports = ({ env }) => ({
connection: {
client: 'postgres',
connection: {
host: env('DATABASE_HOST', '127.0.0.1'),
port: env.int('DATABASE_PORT', 5432),
database: env('DATABASE_NAME', 'db_name'),
user: env('DATABASE_USERNAME', 'postgres'),
password: env('DATABASE_PASSWORD', 'postgres'),
ssl: env.bool('DATABASE_SSL', false),
},
},
});
Your dependencies under app_name/package.json should be like
"dependencies": {
"#strapi/strapi": "4.1.8",
"#strapi/plugin-users-permissions": "4.1.8",
"#strapi/plugin-i18n": "4.1.8",
"pg": "8.6.0"
}

[2023-02-19 11:27:27.199] error: password authentication failed for user "root"
FIX==>
su - postgres
psql postgres
CREATE ROLE root SUPERUSER LOGIN PASSWORD 'password';
The point of interest here is the module used with strapi .
configuration file database.js
module.exports = ({ env }) => ({
defaultConnection: "default",
connection: {
client: "postgres",
connection: {
host: "127.0.0.1",
port: 5432,
database: "dbname",
username: "postgres",
password: "password",
ssl: false
},
debug: true,
useNullAsDefault: true
}
});
version package.json

In my node application i am connecting to a postgres sql in remote system
I have the following connection code:
var sequelize = new Sequelize('postgres://username:password#xxx.xxx.xx.xx:5432/dbname');
Its working fine.. but the following connection is not working:
// initialize database connection
var sequelize = new Sequelize(
config.dbname,
config.username,
config.password, {
dialect: 'postgres',
port:'5432'------------------->specified port here..
});
My config file:
{
"server": {
"port": 3000,
"forks": 1,
"siteUrl": "http://xxx.xxx.xx.xxx:3000"
},
"dbpostgres": {

}
I am receiving the following error:
"Error: connect ECONNREFUSED"," at errnoException (net.js:770:11)","
Please help me to solve this..Thanks in advance.....
