[nginx] nginx + spawn-fcgi + wsapi/lua（搭建lua的web dev平台）

来源：互联网发布：yum y什么意思编辑：程序博客网时间：2024/06/05 16:18

nginx, web server

spawn-fcgi, 一个 fastcgi wrapper

wsapi.fcgi, WSAPI是针对lua的web标准，wsapi.fcgi就是把fcgi请求变成wsapi协议。

FreeBSD 8.1

安装 wsapi-fcgi

/usr/ports/www/fcgi

# pkg_add -r fcgi-devkit

# luarocks install wsapi-fcgi

安装 spawn-fcgi

/usr/ports/www/spawn-fcgi

# pkg_add -r spawn-fcgi

启动 spawn-fcgi

spawn-fcgi -F 1 -s /var/run/nginx-fcgi.sock -P /var/run/nginx-fcgi.pid -U nobody -- /usr/local/bin/wsapi.fcgi

安装nginx

/usr/ports/devel/pcre

# pkg_add -r pcre

下载 nginx-0.8.54

# ./configure && gmake install

---------------- nginx.conf ----------------

worker_processes 1;

events {

worker_connections 1024;

}

http {

server {

listen 8080;

server_name localhost;

location / {

fastcgi_pass unix:/var/run/nginx-fcgi.sock;

fastcgi_index hello.lua;

fastcgi_param SCRIPT_FILENAME /home/kasicass/sandbox/kepler/wsapi$fastcgi_script_name;

}

-----------------------------------------------

启动 nginx

# /usr/local/nginx/sbin/nginx

WSAPI Hello World Program

------------------ hello.lua ---------------------

#!/usr/bin/env wsapi.cgi

module(..., package.seeall)

function run(wsapi_env)

local headers = { ["Content-type"] = "text/html" }

local function hello_text()

coroutine.yield("<html><body>")

coroutine.yield("Hello WSAPI!")

coroutine.yield("PATH_INFO: " .. wsapi_env.PATH_INFO .. "")

coroutine.yield("SCRIPT_NAME: " .. wsapi_env.SCRIPT_NAME .. "")

coroutine.yield("</body></html>")

end

return 200, headers, coroutine.wrap(hello_text)

end

---------------------------------------------------

然后通过浏览器访问：

http://127.0.0.1/hello.lua

碰到的问题

spawn-fcgi 中的 "-U nobody" 参数，让 spawn-fcgi 以 nobody 权限启动。否则 nginx worker (nobody权限) 无法正确 connect()。

http://serverfault.com/questions/101983/nginx-php-fastcgi-fails-how-to-debug

nginx.conf 配置中 "fastcgi_index hello.lua;" 让 127.0.0.1/ 的访问变成 127.0.0.1/hello.lua
