Apache ab will not work - ab: invalid URL when testing python cyclone

Question

I am trying to ab test cyclone.

When I run

ab -n 2000 -c 25 http://127.0.0.1 

I get ab: invalid URL.

Well...when I go to ff on my dev machine, the site is there.

Here is my nginx config

http {      upstream frontends {         server 127.0.0.1:8051;     }      ##     # Basic Settings     ##      sendfile on;     tcp_nopush on;     tcp_nodelay on;     keepalive_timeout 30;     types_hash_max_size 2048;     # server_tokens off;     # server_names_hash_bucket_size 64;     # server_name_in_redirect off;      include /etc/nginx/mime.types;     default_type application/octet-stream;          # Only retry if there was a communication error, not a timeout         # on the Tornado server (to avoid propagating "queries of death"         # to all frontends)         proxy_next_upstream error;      server {         listen   80;         server_name 127.0.0.1;                  location / {             proxy_pass_header Server;             proxy_set_header Host $http_host;             proxy_redirect false;             proxy_set_header X-Real-IP $remote_addr;             proxy_set_header X-Scheme $scheme;                  proxy_pass http://frontends;         } 

Answer 1

ab requires a trailing slash after the URL.

This should work:

ab -n 2000 -c 25 http://127.0.0.1/
