このWikiもそうだけど、OpnePNEなどのPHPで動くコンテンツは、ユーザ数が増えてくると重～くなるそうな・・・というわけで、Xchacheを入れてみることにする。例によって、
piano:root {203} % locate xcache
/usr/ports/www/xcache
/usr/ports/www/xcache/Makefile
/usr/ports/www/xcache/distinfo
とのことなので、
piano:root {204} % portinstall www/xcache
すると、
----------------------------------------------------------------------
Libraries have been installed in:
/usr/ports/www/xcache/work/xcache-1.2.2/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
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

*****************************************************************************
You have installed the xcache package.
To enable it copy the /usr/local/share/examples/xcache/xcache.ini sample
config file into /usr/local/etc/php/ and modify it to suit your needs.
*****************************************************************************
piano:root {205} % cp /usr/local/share/examples/xcache/xcache.ini /usr/local/etc/php/
/usr/local/etc/php.ini に追加設定が必要か？とおもったけど、
http://piano.smb.net/~openpne/phpinfo
で確認したら、
| additional .ini files parsed | /usr/local/etc/php/extensions.ini, /usr/local/etc/php/xcache.ini |
ということで、/usr/local/etc/php/xcache.ini の設定が反映されてました。
/usr/local/etc/php/extensions.ini の内容を/usr/local/etc/php.ini にも書き込んでいたら、Cron <root@piano> sh /usr/home/openpne/bin/tool_rss_cache.cron /usr/home/openpne/bin/ /usr/local/bin/php が動作したとき、
PHP Warning: Module 'XCache' already loaded in Unknown on line 0
というエラーが報告されました。これは、
extension = xcache.so
がPHP起動時に二回呼び出されたためのモノのようです。
