Started this thing called NodeJs and i thought it was cool, i used it for the backend of a yet to be finished mobile-App. Cool right. i was crazy about it until i had it deployed on a borrowed cloud server(ubuntu). To Freshers lemme Explain how it is done
STEP 1:
Install NodeJs on the cloud server,
apt-get install nodejs.
check version by
npm -v
STEP 2:
Transfer Code?repo Unto Cloud Server using WinSCP or other ssh third part apps
STEP 3:
Navigate to the folder where the nodejs code is and do a
node filename.js
and what do u see?
Voila ERRORS!! Intentional
Apparently Ubuntu has a conflict so it uses the
nodejs keyword instead of
node as used on windows.
STEP 4:
So i tried to consume my new service on my 'borrowed ' cloud server. And it didnt work!!!! after so much happiness?This is spiritual!
So i found out putty had closed connection and hence closed session to the server hence the unavailability to reach Server.
So i wanted it to run forever. i searched and found this wonderful script. Wonderful,
noHup nodejs filename.js &
That worked for a while until my mochahost server decided to do a maintenance on a weekend. They did and they didnt start up my server.
Crazy abi? Was i expecting them to before? So i wanted a solution. So i searched further. Got another called
Forever
Forever does the Job perfectly, restarts your server incase of 'iranu'(errors).
STEP 5:
Install forever using
sudo apt-get install forever --global
DONE!!! But it doesnt recognize the NodeJs used as keyword hence it reports 'file not found' on doing a 'forever list'.
So i found an alternative.
Install node-legacy by:
sudo apt-get install nodejs-legacy
That fixed it.
So Forever has a couple of operands:
Three most important ones are : start, stop and list.
LIST lists all the processes being run by the forever service;
Look at the circled red stuff, That is the process id;
This can also be achieved by using the
'ps aux| grep nodejs'
STOP as usual stops the process i.e
'forever stop [process_id]',
equivalent to the kill -9 [ubuntuprocess_id]
START:
Starts a forever process for the nodeJs server
'forever start filename.js'
Voila! You have Set Up That Server. !!
