Apache – How to view the complete httpd configuration


I'm trying to figure out what is the full complete configuration of an httpd setup.

All the configurations files are scattered in different files (/etc/httpd/conf.d, httpd.conf, various mod configs)

Is there a way to list the final httpd configuration?
Like the whole running setup configuration in a single file?

As noted by arco444, you can use apachectl -S to display an overview of the VirtualHosts currently running from the configs, and apachectl -M to display all currently loaded modules - I'm not aware of a tool to display the verbose output of all configs parsed (and which order they were parsed in) at launch of httpd, but I would recommend that you familiarise yourself with the general structure of the httpd config files:

Of particular note to your question: the 'main' apache config file is located in /etc/httpd/conf/httpd.conf (in the region of line 221 on a default httpd installation from the repos included in CentOS 6, which I assume you are using based on your post tags), and the 'supplementary' config files are located in /etc/httpd/conf.d and require to be included explicitly in the main config file. For example, if you search the httpd.conf file for the term 'Include', you will find the line Include conf.d/*.conf which is what includes all files of extension .conf in the subdirectory conf.d - in alphabetical order, so you will want to familiarise yourself with the importance of config file parsing at some point if possible.

As an aside, if you are using a shell based text editor such as vim, I suggest that you enable line numbering and syntax highlighting by default so that such lengthy config files are a bit easier to parse yourself and navigate - in the case of vim, you'd do so by creating a file in your home directory called .vimrc (or append to an existing one) and add the following lines:
