Question

Ubuntu 16.04 mean.js installation (without using one click app)

Posted June 17, 2017 10.2k views
Node.jsMEANUbuntu 16.04

I am trying to install mean.js on my ubuntu 16.04 using the following guide. And I keep getting stuck at the grunt stage.

https://www.digitalocean.com/community/tutorials/how-to-install-a-mean-js-stack-on-an-ubuntu-14-04-server

There were issues with building node so I install using nvm
https://www.digitalocean.com/community/tutorials/how-to-install-node-js-on-ubuntu-16-04#how-to-install-using-nvm

Then there were issues with bower where the process was killed. Managed to solved that by adding swap. I have the 512 MB ram settings.
https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-14-04

Now my problem is grunt. I now have this error.

/opt/mean$ grunt
A valid Gruntfile could not be found. Please see the getting started guide for
more information on how to configure grunt: http://gruntjs.com/getting-started
Fatal error: Unable to find Gruntfile.

Then when I tried

/opt/mean$ npm install
npm WARN checkPermissions Missing write access to /opt/mean/nodemodules/tiny-lr/nodemodules
npm WARN checkPermissions Missing write access to /opt/mean/nodemodules/tiny-lr/nodemodules/body-parser/nodemodules

This is my second droplet try.

If anyone need me to edit the question or require more information, just leave a message.

Hi @tengyong80

From looking at the error log, it looks like you don’t have permissions to the /opt/mean directory with the current user you’re logged in as.
So either change permissions to allow that user access - or run the commands as root or with sudo.

@tengyong80

You’re totally right, when you use sudo you don’t need to use the root login, but your first post didn’t use sudo or root.

All the errors involves some type of permissions problem, so have a look at these:
https://docs.npmjs.com/getting-started/fixing-npm-permissions

I created a new droplet and instead of using the previous tutorials
cd /opt/mean
sudo npm install

I am using npm install as per https://github.com/meanjs/mean
So I am now getting errors only at the Mongo part.
Do you have any idea on why this is happening?

I am using the guides here
https://www.digitalocean.com/community/tutorials/how-to-install-mongodb-on-ubuntu-16-04
https://www.digitalocean.com/community/tutorials/how-to-install-and-secure-mongodb-on-ubuntu-16-04

I added the administrative user for Mongo as below. myuser and mypassword are placeholder for our discussion here. I thought this would have solved the authorized issue.

use admin
db.createUser(
{
user: “myuser”,
pwd: “;mypassword”,
roles: [ { role: “userAdminAnyDatabase”, db: “admin” } ]
}
)

$ npm start

I will implement that security feature next time.

I did what you highlighted and I got the below after I ran npm install in the project folder.
It’s only 3 warning but meanjs doesn’t seem to be running.

    But that’s the install - that will not run the project.
    Have a look in the log files - there is usually an answer saved there :-)
    And in the future, please use the </> button in the comment editor to save the formatting of your code - and also make it easier to read.

    Formatted code will look like this. And can contain _ without making text italic

Yeap I got excited. I ran npm start and I still got the same error.

    Can you run this to verify the users and their grants:

    mongo --port 27017
use admin
db.auth("myuser", "mypassword")
show users

    And which user are you connecting with in your Node app configuration?

Below are the users generated.
I don’t know which user are connected to the Node app.

        "user" : "ktyc",

    So you need to look in your configuration of your Node app - it’s usually in a file called config.js, but again, this can be different depending on your app.
    Did you create it yourself, then you should know. If it’s a project, you’ve downloaded, then just paste a link here and I’ll try to see if I can find the config.

My answers were rejected as spam. I am not sure why.
I suspect I misused the link funtion here.

I created an account in pastebin with the reply I intended.
I hope it works.

Unless there is another way to verify this?

I tested a few iterations before I get to this point..

After I execute

sudo nano /etc/mongod.conf

Then commented

#security:
#  authorization: "enabled"

All the mongo error went away.

After I execute

npm start

as per https://github.com/meanjs/mean
I get the Mean.js test page :)

I don’t think this is the right way though.
So the problem is still not solved.
There has to be a better solution.

Anyway before I commented the mongod.conf.
It generated the errors below.

After I commented the mongod.conf, no more errors.
