I have problem with apache, when I get configure a LAMP then I write:

sudo apt-get install apache2

And everything been fun, but next I wrote

cd /etc/apache2/mods-available

sudo cp * /etc/apache2/mods-enabled

And when I start a apache I get error log

"* Starting web server apache2                                                                    * 

 * The apache2 configtest failed.

Output of config test was:

apache2: Syntax error on line 140 of /etc/apache2/apache2.conf: Syntax error on line 1 of /etc/apache2/mods-enabled/lua.load: Cannot load /usr/lib/apache2/modules/mod_lua.so into server: /usr/lib/apache2/modules/mod_lua.so: cannot open shared object file: No such file or directory

Action 'configtest' failed."

How I can repair this? Please give a simple council because this is my first time on ubuntu. (I have ubuntu 14.04 LTS)
