> Hello. I successfully installed asterisk 12.4.0 with lua and use lua_pbx with my dialplan, but I need to use mysql.
> I installed luasql.mysql and without extensions.lua it work fine (woth external scripts)
> I tested it with my little script:
> {noformat}
> function mysqltest()
> local driver = require "luasql.mysql"
> local env = assert(driver.mysql())
> local con = assert(env:connect("mydb", "root", "mypass", "localhost", 3306));
> local cur = assert(con:execute("SELECT version()"));
> print("<mysql> MYSQL driver version is: "..driver._MYSQLVERSION);
> print("<mysql> "..driver._COPYRIGHT);
> print("<mysql> "..driver._DESCRIPTION);
> print("<mysql> "..driver._VERSION);
> cur:close()
> con:close()
> env:close()
> end;
> mysqltest()
> {noformat}
> when I called it as 
> >lua mysqltest.lua 
> I see response:
> {noformat}
> <mysql> MYSQL driver version is: 5.5.37
> <mysql> Copyright (C) 2003-2012 Kepler Project
> <mysql> LuaSQL is a simple interface from Lua to a DBMS
> <mysql> LuaSQL 2.3.0
> {noformat}
> when I tried require driver from extensions.lua, I see this when reload module pbx_lua.so:
> module reload pbx_lua.so
> {noformat}
> No such module 'pbx_lua.so'

> I uses this issue for fixing problem, but it does not
> ASTERISK-17279 
> So at weekend I deep googled this problem and found some things:
> At previous issue (17279) another things I find that I need to load pbx_lua module with global simbols. I found a the old file modules.conf (at asterisk like  1.6) was section [globals] that includes at itself modules that must be loaded with golbal simbols:
> lua_pbx.so=yes
> So I changed my modules.conf but it no affect. So my Question changed from :
> How I must install lua to my server for wotrking with luasql.mysql at extensions.lua?
> to:
> How to load Asterisk module with global simbols? 
> I thiks that is write question.
