如何在Linux服务器上部署Node.js和MongoDB应用程序

Question

I am developing an app and I want to deploy it on a linux server. I already have copy my local files to the server . I have read this article but not so clear to me https://github.com/keystonejs/keystone/issues/4687 .

things i have already done

Remote server has appropriate versions of Node.js & npm installed (ideally the same as what you have been testing with in development)

Check out (or copy) the latest version of your application source to the remote server.

Run npm install (or npm install --production if this will be a production environment) in the top-level of your application source directory.

but when i run npm start on the server it gives me error which is

Mongoose connection "error" event fired with: { MongoError: failed to connect to server [localhost:27017] on first connect

my settings

keystone.init({
    'name': 'Test',
    'brand': 'Test',
    'sass': 'public',
    'static': 'public',
    'favicon': 'public/favicon.ico',
    'auto update': true,
    'views': 'templates/views',
    'view engine': '.html',
    'custom engine': cons.nunjucks,
    'mongo': 'mongodb://localhost/test',
    'auto update': true,
    'emails': 'templates/email',
    'session': true,
    'auth': true,
    'user model': 'User',
});

Do i need to configure more settings on mongo on the server?

Answer 1

Mongoose connection "error" event fired with: { MongoError: failed to connect to server [localhost:27017] on first connect

The above error means that your mongodb service was not started.

To enable & start the mongodb service you can run following command:

1. Enable mongodb service

sudo systemctl enable mongod.service

2. Start mongodb service

sudo service mongod start

3. Start your nodejs app

npm start
