Using Lua 5.2 with wsapi 1.6-1 and wsapi-fcgi 1.6-1 installed via luarocks, I have the following nginx configuration:
server {
listen 127.0.0.1:8080;
server_name localhost;
location / {
root /home/petsagouris/code/wsapitest/;
index index.html index.htm run.lua;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
# Lua WSAPI
# taken from http://mascarenhas.github.io/2009/10/24/wsapi-nginx-fcgi.html
location ~ ^(.+\.lua)(.*)$ {
root html;
fastcgi_pass 127.0.0.1:9100;
fastcgi_index run.lua;
fastcgi_split_path_info ^(.+\.lua)(.*)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
The launcher script is this:
#!/usr/bin/env lua
# filename: run.lua
local fastcgi = require"wsapi.fastcgi"
local app = require"app"
fastcgi.run(app.run)
and the actual app is this one:
#!/usr/bin/env wsapi.cgi
# filename: app.lua
local coroutine = require "coroutine"
local M= {}
_ENV = M
function run(wsapi_env)
local headers = { ["Content-type"] = "text/html" }
local function hello_text()
coroutine.yield("<html><body>")
coroutine.yield("<p>Hello Wsapi!</p>")
coroutine.yield("<p>PATH_INFO: " .. wsapi_env.PATH_INFO .. "</p>")
coroutine.yield("<p>SCRIPT_NAME: " .. wsapi_env.SCRIPT_NAME .. "</p>")
coroutine.yield("</body></html>")
end
return 200, headers, coroutine.wrap(hello_text)
end
return M
Both of them are executable at the moment (do I just need the run.lua to be executable or I have to keep both like that?) and I can get the correct responses from the command line when I go for $ ./run.lua or $ ./app.lua
When I visit localhost:8080 I get a "502 Bad Gateway" response and the following log line:
2013/11/19 09:02:51 [error] 31359#0: *26 connect() failed (111: Connection refused) while connecting to upstream, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9100", host: "localhost:8080"
I find it really weird that I can get the scripts to work properly via the command line but they don't work when hit from the server. Anyone that can help me out with this?
