CentOS 7 httpd modules missing

Finally I decided to migrate CentOS 5 to 7 but I can't get the httpd modules from yum or within the server.

I read that we can't blindly use apache 2.2 config with 2.4 and module names might been changed or removed. How do I figure out what has it changed to?

How do I get the modules from yum? yum whatprovides mod_authz_default.so returns no package.

I keep commenting out one by one, it'll list out the next one. Yes there are modules in /usr/lib64/httpd/modules but not the ones that old httpd.conf needs.

Solution 1:

It seems these modules have been removed from apache 2.4: mod_authn_default, mod_authz_default, mod_mem_cache. Refer apache upgrade doc

For mod_ident.c and other modules I downloaded the source from GitHub and compiled it.

Example:

[root@myhost ~]# wget https://raw.githubusercontent.com/omnigroup/Apache/master/httpd/modules/metadata/mod_ident.c

[root@myhost ~]# apxs -a -i -c  mod_ident.c
