Movable TypeなどでまだまだPerlの需要があります。
今回はNginxでPerlを動かす手順のご紹介。
epelリポジトリの導入します。

# wget http://ftp-srv2.kddilabs.jp/Linux/distributions/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm # rpm -ivh epel-release-6-8.noarch.rpm |
Perl関連のモジュールをインストールします。
|
1 |
# yum install perl perl-CGI spawn-fcgi fcgi-devel |
fcgi-perlをインストールします。
|

# yum install fcgi-perl --enablerepo=epel |
起動スクリプトの作成

Perlを動かす為fastcgiのスクリプトを作成します。

実行権限をつけて
|
1 |
# chmod +x /usr/bin/fastcgi-wrapper.pl /etc/rc.d/init.d/perl-fastcgi |
起動・自動起動設定を行います。
|
1 2 3 |
# /etc/rc.d/init.d/perl-fastcgi start # chkconfig --add perl-fastcgi # chkconfig perl-fastcgi on |
これでPerlのcgiファイルを実行できるようになります。
|
1 2 3 |
# lsof -i:8999 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME fastcgi-w 3712 root 3u IPv4 20514 0t0 TCP localhost:bctp (LISTEN) |
Port8999番にてperl-fastcgiが起動している事がわかります。
Nginxのコンフィグを設定します。
cgiを使いたいホストのコンフィグファイルに以下の内容を挿入する。
|
1 2 3 4 5 6 7 8 9 10 |
(略) location ~ \.cgi$ { #fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock; fastcgi_pass 127.0.0.1:8999; fastcgi_index index.cgi; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } # location ~ \.cgi$ (略) |
cgiファイルにアクセスがきた時に後方のperl-fastcgiに渡してあげる。
これで大丈夫。
お疲れ様です。
