I have a problem running workload from fb-oss-performance benchmark. I get the following error from every ip I use. Even localhost has the same problem. please guide me. Thanks.

`root@zahra:/home/zahra# docker run --net=host --name=fb -v /home/zahra/cmd.sh:/oss-performance/cmd.sh cloudsuite/fb-oss-performance:4.0

Hello, Can you show all the commands you use to run the workload? It seems that your way of setup the database is not expected. Are you also using the database docker image provided in CloudSuite?

Best,

Hello, Thank you for your response.

Yes, I did all the installation and execution steps according to the document in the link https://github.com/parsa-epfl/cloudsuite/blob/main/docs/benchmarks/fb-oss-performance.md

Only in "docker run --name=siege -dt --net=host cloudsuite/siege:4.0.3rc3 " I did not consider , because siege host is the same as fb-oss-performance: 4.0.

I put the content of the cmd.sh file as follows:

> .#!/bin/bash
> 
> set -eu
> 
> LOCAL_IP=$(ip route get 1.0.0.0 | grep src | cut -d' ' -f7)
> 
> echo "The IP address is $LOCAL_IP"
> 
> .# mysql server ip
> MYSQL_IP=$LOCAL_IP
> SIEGE_IP=$LOCAL_IP
> 
> 
> .# Max connections >1000 required for mediawiki workload. If mysql already has max_connections > 1000 comment the below line.
> mysql --host=$MYSQL_IP --user=root --password=root -e "SET GLOBAL max_connections = 1001;"
>

The error I am currently experiencing is as follows:

`root@zahra:~# docker run --net=host --name=fb -v /home/zahra/cmd.sh:/oss-performance/cmd.sh cloudsuite/fb-oss-performance:4.0

Hello,

If you carefully check the error message:

ssh: connect to host 192.168.134.67 port 9801: Connection refused

You can find that the problem is because of the server running siege. It either has the 9801 occupied by other applications, or the server is listening on the wrong IP address. In this case, you should first check the occupation, and then maybe strictly follow the guideline to set up the siege server.

I solved the port problem but now I get the following error:

Isn't this the same problem you faced in the beginning?

Yes, it is true, but when I solve the problem of this error, I encounter the following error:

While outside the docker run command, the ssh 10.18.0.85 -p 9801 command works without an access permission error and without asking for a password.

Another problem I noticed is that siege container is not added to the running container (docker ps) . Unless "--net=host" removed from the command "docker run --name=siege -dt --net=host cloudsuite/siege:4.0.3rc3".

xusine commented 2 years ago

First of all, the ssh run by hhvm is actually the siege docker. As far as I remember, our siege docker uses Debian image, so it should never give you Ubuntu prompt when you log in unless you are logging in to your own operating system. Second, you should definitely check what happens when running siege if siege docker is not on the active list. Do you face any errors when running siege?
