ok, let me check. For Amazon Linux AMI the install script method (which you are using) should work

@Tanvir Sadik Shaikh I just tested this on Amazon Linux 2 AMI in a t2.medium machine and it successfully installed for me. 1. Can you take a latest pull of the code and try again. We released a new version(

v0.4.1

) a few hrs back. 2. What is the machine you are trying to install SigNoz? - t2.medium? - SigNoz would need min 3-4 GB RAM machine to get installed

@User some application already running on port 8080?

Ankit Nayan

09/28/2021, 4:59 PM

try changing ports at https://github.com/SigNoz/signoz/blob/main/deploy/docker/clickhouse-setup/docker-compose.yaml#L29 to

8081:8080

and re-run

./install.sh

Ankit Nayan

09/28/2021, 5:00 PM

Tanvir Sadik Shaikh

09/29/2021, 6:20 AM

@User "try changing ports at https://github.com/SigNoz/signoz/blob/main/deploy/docker/clickhouse-setup/docker-compose.yaml#L29 to

8081:8080

and re-run `./install.sh`" this worked for me, but same issue is coming for frontend port 3000. already in use because i am using that port for our application.

Ankit Nayan

09/29/2021, 6:52 AM

@User you can change port for frontend at https://github.com/SigNoz/signoz/blob/main/deploy/docker/clickhouse-setup/docker-compose.yaml#L54

Ankit Nayan

@Ankit Nayan while running this cmd OTEL_METRICS_EXPORTER=none OTEL_EXPORTER_OTLP_SPAN_ENDPOINT="http://<IP of SigNoz Backend>:55681/v1/trace" LS_SERVICE_NAME=<service name> node server_init.js, i am facing below port number issue 3001 that is already in use.

Ankit Nayan

10/04/2021, 10:29 AM

as I last remember you changed the port of signoz frontend to 3009 right? Then nothing that is part of should be running at port 3001. This might be some of your applications. Run

lsof -i tcp:3001

and find out what command was used that is running a process at 3001

Tanvir Sadik Shaikh

10/04/2021, 10:55 AM

3001 already in use, is it possible to use 3002, if yes where i need to make the changes

Ankit Nayan

10/04/2021, 11:12 AM

change this line to

- "3002:3000"

and 3000 to 3002 at this line if you use

./install.sh

Tanvir Sadik Shaikh

10/04/2021, 11:38 AM

here i already done the changes to 3009 but still the error is showing

Ankit Nayan

10/04/2021, 11:47 AM

whats the output of

lsof -i tcp:3001

Tanvir Sadik Shaikh

10/04/2021, 12:01 PM

this is the output

Ankit Nayan

10/04/2021, 12:08 PM

some nodejs application is run using PM2 command...please check

Tanvir Sadik Shaikh

10/04/2021, 12:10 PM
