Ah but the joys of trying to match the missing module with its obtuse apache error. In this case, we tried to use the TypesConfig directive but the module wasn’t loaded at runtime. Here’s the error:

# service httpd configtest
Syntax error on line 107 of /etc/httpd/conf/httpd.conf:
Invalid command 'TypesConfig', perhaps misspelled or defined by a module
not included in the server configuration

In this case, we were missing the mime module. You can add that module in your httpd.conf file with the following directive:

LoadModule mime_module modules/mod_mime.so

Happy apaching!
