用 perl 写一个 daemon 程序来处理 cgi 文件:
vi /usr/local/bin/cgiwrap-fcgi.pl
- #!/usr/bin/perl -w
- use FCGI;
- use Socket;
- use FCGI::ProcManager;
- sub shutdown { FCGI::CloseSocket($socket); exit; }
- sub restart { FCGI::CloseSocket($socket); &main; }
- use sigtrap 'handler', \&shutdown, 'normal-signals';
- use sigtrap 'handler', \&restart, 'HUP';
- require 'syscall.ph';
- use POSIX qw(setsid);
- #&daemonize; we don't daemonize when running under runsv
- #this keeps the program alive or something after exec'ing perl scripts
- END() { }
- BEGIN() { }
- {
- no warnings;
- *CORE::GLOBAL::exit = sub { die "fakeexit\nrc=" . shift() . "\n"; };
- };
- eval q{exit};
- if ($@) {

- }
- &main;
- sub daemonize() {
- chdir '/' or die "Can't chdir to /: $!";
- defined( my $pid = fork ) or die "Can't fork: $!";

注意文件中的这两行:
#$socket = FCGI::OpenSocket( "127.0.0.1:8999", 10 );
#$socket = FCGI::OpenSocket( "/var/run/nginx/perl_cgi-dispatch.sock", 10 );
这两行都表示监听来自 perl CGI 的请求。
其中 perl_cgi-dispatch.sock 表示使用 unix socket 响应 CGI 请求。
127.0.0.1:8999 表示使用 TCP/IP 协议响应请求。
需要使用哪种方式就在下面的 FCGI::OpenSocket 中填入相对应的内容。
启动:
chmod +x /usr/local/bin/cgiwrap-fcgi.pl
/usr/local/bin/cgiwrap-fcgi.pl > /dev/null 2>&1 &
配置 Nginx 的 location 处理 cgi 文件:
location ~ .*\.cgi$ {
fastcgi_pass 127.0.0.1:8999;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
测试:
在 web 的根目录下创建一个 cgi 文件:
vi test.cgi
#!/usr/bin/perl
print "Content-type: text/html\n\n";
print "Hello, world.";
文件需要有可执行权限:
chmod +x test.cgi
访问 http://www.domain.com/test.cgi 看看有没有输出。
