Can't install and run server with systemd, CentOS 7.5 x64

[vkukh]

Hello! I installed Impress on CentOS 7.5 x64. I was able to run the server just under the root, "impress start" gave a port error, so I ran it through the "node server &", the error got out too, but the server was working. The server is working now, but how can I track the process (stop) and "systemctl status impress" shows

● impress.service - Impress Application Server

@newGermes do you have something in impress log folder?
@belochub please investigate this case and give your proposals.

Based on your logs лип 20 20:20:46 rider sh[25591]: /bin/sh: impress: command not found the systemd unit couldn't find the impress startup binary. Did you perhaps install Impress manually or did you use the deploy script?

I installed three times:

1. npm install impress
2. uploaded and launched deploy/centos7x64.sh (can't be launched)
3. npm install impress (i got the same error like in first)

[lundibundi]

And what is the error for the script? (deploy/centos7x64.sh)

If it was something like 'not executable' or 'not found' could you try to sudo chmod +x centos7x64.sh and then sudo centos7x64.sh assuming you are in the same directory where you downloaded the script.

[vkukh]

I'm sorry. I don't remember. I can do this from scratch one more time if you give me advice in which way it would be more preferable. Thank you!

P.S. File centos7x64.sh was executable

[lundibundi]

Well, then just try to run sudo ./centos7x64.sh (or just ./centos7x64.sh if you are root) on a clean system (I'm assuming you are installing Impress globally for this use case Installation scripts for an empty server (from the scratch) ). That should do it, no need for npm install or anything, the script should do it by itself. If it fails then just paste the log here.

[vkukh]

Ok. Thank you!

[vkukh]

I have installed with an approach: "sudo ./centos7x64.sh"

1. After I launched "sudo impress start":

[lundibundi]

Thanks, that's a bug in Impress. We will fix it and get a new version available soon.

For anyone interested: https://github.com/metarhia/impress-cli/blob/master/cli.js#L182 in fs.unlink callback parameter is no longer optional since node 10.
I'll submit a PR later if no one does this before me.
Also we should probably scan impress/impress-cli for such usages as it may not be the only one.

[vkukh]

Thank you for this product ;-) I will be waiting for update.
