evasive module in apache error: "Can't locate API module structure `evasive24_module'"

Question

I wanted to protect my Apache/2.4.6 (CentOS) server in CentoOS 7 from DDOS attacks so after searching for some alternatives I found this page. They go through the installation of the modules evasive and security pretty easy. So I started first by installing the modules:

# yum update && yum install mod_security mod_evasive 

Then, I added this two lines to my config file:

LoadModule evasive20_module modules/mod_evasive24.so
LoadModule security2_module modules/mod_security2.so

and now that I try to start my server I get the following error:

httpd: Syntax error on line 375 of /etc/httpd/conf/httpd.conf: Syntax error on line 2 of /etc/httpd/conf.d/mod_evasive.conf: Can't locate API module structure `evasive24_module' in file /etc/httpd/modules/mod_evasive24.so: /etc/httpd/modules/mod_evasive24.so: undefined symbol: evasive24_module

Have anybody had this similar problem? Any tips or ideas of how can I solve this?
