Installation of OpenFlow

rehan.quresh · December 27, 2022, 2:05pm

Hi,

I’m trying to install ’ Normal version’ (GitHub - open-rpa/docker) of RPA on windows 2019 server. Since it is server I’m unable to install Docker properly.

It is showing below error for docker:
docker: Error response from daemon: failed to start service utility VM (createreadwrite): hcsshim::CreateComputeSystem c65f371c9022928da3ffcdd1060b926bf3c0f34973741d59a93faf6c833e1a0b_svm: The virtual machine could not be started because a required feature is not installed.

I want to know, Is there any alternate option other than Docker to install normal version on a server ?

Install openflow using npm :HERE IS THE LINK FOR IT

rehan.quresh · December 27, 2022, 5:22pm

Thank you for helping.

I installed openflow using the link you provided but on port 80 some other service is running because of that I’m unable to access --localhost.openiap.io.

I tried changing port number in openflow.env but it is not changing.

Q1. Please help me in changing the port number

Q2. How do I install openRPA tool on server.
Shall I download the .exe and change domain from settings.json

Update the envoriment file then run openflow-cli —install again.
there is no .exe but you can download an .msi installer from github. And you define the openflow url in documents/openrpa/settings.json under wsurl

Thank you @Allan_Zimmermann

I changed the port number in env file but while executing the command I got below error.
Note: While installing pm2-service-install, I entered yes for Set PM2_HOME: and gave path

PS E:\OpenRPA> openflow-cli --init

you need to follow the guide at deploy openflow using NPM | openflow

rehan.quresh · December 28, 2022, 7:02pm

Hi @Allan_Zimmermann

I followed the guide but unable to overcome this error. Please help!!

C:\openflow>openflow-cli --init
init

}

Allan_Zimmermann · December 28, 2022, 7:28pm

you can ignore the error about docker not being installed.
after install, you can check if it worked using

pm2 list

rehan.quresh · December 29, 2022, 5:33am

When I access http://localhost.openiap.io/ —It says ‘This site can’t be reached’

Result of
C:\openflow>openflow-cli --install openflow
install
NodeJS version v18.12.1 Config C:\openflow\openflow.env
Error: connect ENOENT //./pipe/docker_engine
at PipeConnectWrap.afterConnect [as oncomplete] (node:net:1300:16) {
errno: -4058,

address: ‘//./pipe/docker_engine’
}

I did – C:\openflow>netstat -nba | FINDSTR “LISTEN” | FINDSTR “80”
command but couldn’t find anything running on port 80.

Am I missing something ?

Allan_Zimmermann · December 29, 2022, 9:27am

You can check the logs using

pm2 logs

or monitor it, using

pm2 monit

and in a separate console, do

pm2 restart 0

and look for any errors.

I tried to install from beginning following the steps provided in https://openflow.openiap.io/npmopenflow but I got below errors:

Experiencing also this exact problem.
Please help

EDIT:

I can now access the openflow.

I edited the openflow.env file and changed the mongodb_url.
old: mongodb://localhost:27017
new: mongodb://0.0.0.0:27017

rehan.quresh · January 3, 2023, 9:19am

Thank you @at.austria. It worked. You’re a life savior!!

Allan_Zimmermann · January 3, 2023, 10:03am

Hi @at.austria I did not know you could connect to 0.0.0.0 that is normally an broadcast address that symbols “all ip addresses” but I’m glad you found a solution that also works for @rehan.quresh
