JIRA Cloud addon can't start on CentOS platform

Jira Development Jira Cloud
#1

We are constructing a CentOS 6.5 (amd64) platform as our App Server, and moving App Server from Win7 platform to CentOS platform; however, during this process, we run into some issues which never occurred on Win7 platform as follows.

On CentOS platform, I firstly install a global ngrok with ‘npm install ngrok -g’ command, and check it:

$ ngrok -v
$ ngrok version 2.2.8

This ‘ngrok http’ command can establish a local tunnel for HTTP.

On our addon folder, I run ‘npm install’ and then ‘npm start’ command, but the latter hangs forever after ‘Initialized sqlite3 storage adapter’:

$ pwd
/jira/gadget
$ npm start

com.hitachiconsulting.gadget@0.0.1 start /jira/gadget
node app.js

Watching atlassian-connect.json for changes
Add-on server running at http://CDC-Jira-Cloud-01:3000
Initialized sqlite3 storage adapter

ngrok can not establish a local tunnel as expected.

I also find that ‘npm install’ installs a local ngrok on our addon subfolder–node_modules:

$ pwd
/jira/gadget
$ npm install --unsafe-perm
…
ngrok - downloading binary https://bin.equinox.io/a/b87faFPKrii/ngrok-2.1.1-linux-amd64.tar.gz …
ngrok - binary downloaded…
ngrok - binary unpacked.
added 494 packages in 33.291s
$

But this lcoal ngrok does not work as follows:

$ pwd
/jira/gadget/node_modules/ngrok
$ ./bin/ngrok -v
Segmentation fault
$

Would anyone like to give us helps?

Any helps would be appreciated.

Thanks.

@xjiang - I would try downloading directly from ngrok’s website. https://ngrok.com/download . Try their latest stable build.

I am using the latest stable build: 2.28

if I only run ngrok, it is OK:

# ngrok http 8080

But if I run ‘npm start’ command on my gadget folder:

# pwd
/jira/gadget
# npm start

Watching atlassian-connect.json for changes

It hangs here, and I find out ngrok is failed with the following error:

My CentOS is:

On Win7 platform, I am also using ngrok 2.2.8, and it works very well

So I don’t what’s going on, any helps or suggestion?

@xjiang - when you ran ngrok standalone, was it from the binary on Ngrok’s website, or was it from your node_modules/ directory?

I’m guessing it was the standalone, based on your first post (where you’re segfaulting on the node_modules binary). And therefore, this is expected, because when your Node app is calling ngrok, it’s using the binary from the ./node_modules directory.

Just for grins, can you just put the working ngrok executable binary (the one that works) into ./node_modules/ngrok/bin/ (overwrite the one that is segfaulting) and see if you can run npm start without it bailing?
