mod_perl

しばらく追いかけるのをやめているうちにmod_perlはどんどん安定化し、かなり使えるものとなってしまっているようなので(おそい!)使ってみる。
  • BOX: AMD Opteron 1.6GHz x 2, 1GB RAM
  • OS: FreeBSD 7.0-CURRENT #2: Thu Mar 23 12:41:17 JST 2006
  • Apache httpd: 半年ぐらい前のHEADなやつかもしくは2.0.55などのGA、MPMはworker
  • perl: perl 5.8.8
threaded MPMなapacheに組み込む場合、当然だろうけどperlもthreadedにしないといけない。perlがthreadedになっていない場合はperlの入れ直し。FreeBSDでportで入れる場合はWITH_THREADSでmake installすればよい。で、mod_perlのソースを取ってきてビルド。Apache httpdはHEADなやつだとauthまわりでごちゃごちゃしてるのでmakeできないもよう。日々失敗する箇所が変っているのでいじってる最中かも? たまたま半年ぐらい前のHEADなやつがあったのでそれで試してみたらmakeはできた。
$ svn checkout https://svn.apache.org/repos/asf/perl/modperl/trunk/ mod_perl-2.0 $ cd mod_perl-2.0 $ perl Makefile.PL MP_APXS=/home/apache/bin/apxs Reading Makefile.PL args from @ARGV MP_APXS = /home/apache/bin/apxs no conflicting prior mod_perl version found - good. Configuring Apache/2.3.0-dev mod_perl/2.0.3-dev Perl/v5.8.8 ・・・・・ ・・・・・ $ make && make test $ sudo make install
httpd.confに
LoadModule perl_module modules/mod_perl.so
と書いて基本的な設定はおわり。 いきなりモジュールを書くのもアレなので、とりあえずApache httpdに付属のprintenvをModPerl::Registryで動かしてみる。
PerlModule ModPerl::Registry Alias /perl /home/apache/perl <Location /perl> SetHandler perl-script PerlResponseHandler ModPerl::Registry Options +ExecCGI </Location>
と書いてhttpdをrestartして、/home/apache/perlにprintenvを置いてアクセス。をを!動いている(あたりまえ)。 mod_perlなので速いはず、ということで、フツーのCGIとして動くprintenvと比べてみると・・・ いい加減な計測だけど相対的な違いは明らか。かなり速い。安定して動くのならいいなあ。
