uWSGI - WSGI アプリケーションコンテナ


uWSGI は、「ホスティングサービスを構築するためのフルスタックの開発を的とする」ソフトウェアアプリケーションです。プロジェクトでサポートされている最初のプラグインである Web Server Gateway Interface(WSGI; ウィズギー) にちなんで命名されている。

uWSGIは、Cherokee や Nginx などの Web サーバーと組み合わせて Python Web アプリケーションを提供するためによく使用され、uWSGI のネイティブ uwsgi プロトコルを直接サポートする。

Libraries have been installed in:
   /usr/lib64/httpd/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.
----------------------------------------------------------------------
chmod 755 /usr/lib64/httpd/modules/mod_uwsgi.so

#
# Dynamic Shared Object (DSO) Support
#
# To be able to use the functionality of a module which was built as a DSO you
# have to place corresponding `LoadModule' lines at this location so the
# directives contained in it are actually available _before_ they are used.
# Statically compiled modules (those listed by `httpd -l') do not need
# to be loaded here.
#
# Example:
# LoadModule foo_module modules/mod_foo.so
#
LoadModule uwsgi_module modules/mod_uwsgi.so
