Issues in running Benchmark

[shivankgarg98]

I'm not able to run any of the 3 Benchmark. Probably due to some issue with nginx-web-server.

Please look at the following output:

root@localhost:/data/shivank/DeathStarBench/mediaMicroservices# wget localhost:8080
--2021-01-26 16:59:47--  http://localhost:8080/
Resolving localhost (localhost)... ::1, 127.0.0.1
Connecting to localhost (localhost)|::1|:8080... connected.
HTTP request sent, awaiting response...

The above command get stuck. Docker logs for nginx-web-server are as follows:

root@localhost:/data/shivank/DeathStarBench/mediaMicroservices# docker-compose logs nginx-web-server

It's failing to open the tracer file even after I have changed the permission for openresty directory to 777 recursively. Also, I'm not able to understand what's causing the problem.

Any help is appreciated.

Same here. My docker containers serving the frontend keeps restarting.

It seems like the fatal error is due to unsupported instruction set on the CPU. I solved it by migrating the benchmark to another machine and it works fine now.

Hi @shivankgarg98 @hyhuang00 , I've experienced the same issue in my local machine, and it was not my first time with this using Lua.

In my specific case, I use umask 0077 in my ~/.bashrc in order to guarantee default file permissions for my user files. It caused the file socialNetwork/nginx-web-server/jaeger-config.json to be cloned (during repo git clone) without global read permissions, and caused the problem. Setting the read permission to group+others in Linux fs solved my problem and then I was able to get the environment up.

It's failing to open the tracer file even after I have changed the permission for openresty directory to 777 recursively.

Given what I said, try to set the permission for nginx-web-server folder recursively instead of changing the openresty one @hyhuang00.
