摘要：找到含有的一行，去掉前邊的。可能你需要修改的默認(rèn)文檔，在的位置按要求添加即可。寫文件首先我們寫一個(gè)的文件，作用就是會(huì)把我們的后綴修改為。

對(duì)于Apdche這個(gè)東西，絕大多數(shù)人都是非常熟悉的。很多人都會(huì)詬病這個(gè)Apache，說它效率不高而且非常消耗資源，然后會(huì)建議用Nginx。這些不能否認(rèn)，但是我還是很喜歡Apache，因?yàn)樗容^穩(wěn)定。
Apache關(guān)于Lua我不知道是哪一個(gè)版本編譯進(jìn)去了的，但是最新版的是有的。在Apache的bin目錄下有一個(gè)lua51.dll很明顯，這個(gè)是Lua5.1版本的，目前Lua已經(jīng)到了5.3版本了，如果你想追求新的版本的話，你可以自己把a(bǔ)pache編譯一次。然后還有，在Apache的modules目錄下有一個(gè)mod_lua.so是開啟Apache和Lua“通信橋梁”的文件。

找到含有mod_lua.so的一行，去掉前邊的#即可。

找到含有mod_rewrite.so的一行，去掉前邊的#。

可能你需要修改Apache的默認(rèn)文檔，在DirectoryIndex的位置按要求添加即可。

將AllowOverride后邊的None寫為All，表示在整臺(tái)服務(wù)器上都開啟了URL重寫。

首先我們寫一個(gè).htaccess的文件，作用就是會(huì)把我們的Lua后綴修改為php。,內(nèi)容如下：

RewriteEngine on
RewriteCond %{REQUEST_FILENAME}   info
RewriteRule (.*).php    $1.lua [NC]

新建一個(gè)info.lua，寫入內(nèi)容如下：

-- Extend tostring to report function type (C or Lua)
do
  local type, tostr = type, tostring
  function tostring(obj)
    local type, val = type(obj), tostr(obj)
    if type == "function" then
      type = pcall(coroutine.create, obj) and "Lua " or "C " -- coroutines cannot start at a C function
      return type .. val
    else
      return val
    end
  end
end

local safe_replacements = {
  ["<"] = "<",
  [">"] = ">",
  ["&"] ="&",
}
local function safestring(...)
  return tostring(...):gsub("[<>&]", safe_replacements):gsub("

end
local function emstring(...)
  return """.. safestring(...) .."""
end
