apacheのモジュールだけをインストールする方法

該当モジュールのディレクトリにてapxsにてコンパイル、インストールする。インストール時はLoadModuleを勝手に追加してくれる。

$ pwd
/home/foo/httpd-2.0.64/modules/metadata
$ /usr/local/apache2/bin/apxs -c mod_headers.c
/usr/local/apache2/build/libtool --silent --mode=compile gcc -prefer-pic -DDEFAULT_SERVER_LIMIT=1024 -DAP_HAVE_DESIGNATED_INITIALIZER -DLINUX=2 -D_REENTRANT -D_GNU_SOURCE -pthread -I/usr/local/apache2/include  -I/usr/local/apache2/include   -I/usr/local/apache2/include   -c -o mod_headers.lo mod_headers.c && touch mod_headers.slo

----------------------------------------------------------------------
Libraries have been installed in:
   /usr/local/apache2/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
