Another error while starting httpd

Starting httpd: httpd: Syntax error on line 149 of /etc/httpd/conf/httpd.conf: Cannot load /usr/lib/liblua5.1.so into server: /usr/lib/liblua5.1.so: cannot open shared object file: No such file or directory

Fix: yum install lua-devel and the file name.

Umm! That didnt fix the problem.

i fixed the problem. i uncommented liblua5.1.so and httpd started fine i was able to see the mod_security loaded in test.php file.

LoadFile /usr/lib/libxml2.so
#LoadFile /usr/lib/liblua5.1.so
LoadModule security2_module modules/mod_security2.so
