          yes, i have see the error message, but i don't understand the problem
          in google, i don't have find a interesting result.

          do I need to install nginx on my VM, for the test run perfectly ?

            It should run out-of-the-box just fine, but given the error above, sounds like some issue with your system otherwise an upstream nginx bug.

              I Michael,

              I have continued my test/debug for nginx

              I have noted that i obtain the same error when the process doesen't running.

              you can show below different test.
              i have run manually the same test that phorononix solution realize (pre script, test ab, post script)

              after this tests, i thinks that is possible that the process nginx in pre script, doesn't run correctly

              additional information : when i execute lynx command : lynx http://localhost:8088/test.html i obtain a forbidden error

              thanks

                  I do not know why it was working and why it stopped working, but I did run a network trace and it seems that the Apache Benchmark tool which is run to benchmark Nginx is using the IPv6 localhost rather than the IPv4, and Nginx is configured to only listen to the IPv4. So the test fails as you mentioned with a connection attempt error.

                  The solution is to edit the file ~/.phoronix-test-suite/test-profiles/pts/nginx-1.1.0/test-definition.xml
                  And to replace the keywork "localhost" by "127.0.0.1" which will force the benchmark tool to use IPv4 and thus succeed.

                  Note: to Michael Larabel, I've seen your GitHub repos for the pts software, but did not find it for the test profiles. I have no clue how to push you with the fix. Please advise for future!

                    Side note: benchmarking nginx serving static files using ab ("apache benchmark") is funny: ab uses waaaaay more resources to generate load than nginx uses to serve these requests. Needless to say, proper benchmarking of nginx proven to be tricky business. Test could easily end being bottlenecked by ... bechmark tool itself! So to get proper results it usually wise to launch ab on separate powerful physical machine (preferably far more powerful than one running nginx). Else its easy to benchmark ... ab tool itself :-)
