Nginx 运行perl-cgi脚本配置
1. 首先安装 perl 跟 FastCGI 支持模块
#wget http://www.cpan.org/modules/by-module/FCGI/FCGI-0.67.tar.gz
#tar zxvf FCGI-0.67.tar.gz
#cd FCGI-0.67
# perl Makefile.PL
#make && make install
--------------------------------------------------------------------------------------------------
2. 配置 perl FastCGI 的脚本：
将脚本保存为 perl-fastcgi.pl 放 /usr/bin 下 vi /usr/bin/perl-fastcgi.pl 文件内容为：
--------------------------------------------------------------------------------------------------
#!/usr/bin/perl
use FCGI;
#perl -MCPAN -e 'install FCGI'
use Socket;
use POSIX qw(setsid);
#use Fcntl;
require 'syscall.ph';
&daemonize;
#this keeps the program alive or something after exec'ing perl scripts
END() { } BEGIN() { }
*CORE::GLOBAL::exit = sub { die "fakeexit\nrc=".shift()."\n"; };
eval q{exit};
if ($@) {
exit unless $@ =~ /^fakeexit/;
};
&main;
sub daemonize() {
chdir '/' or die "Can't chdir to /: $!";
defined(my $pid = fork) or die "Can't fork: $!";
exit if $pid;
setsid or die "Can't start a new session: $!";
umask 0;
}
sub main {
#$socket = FCGI::OpenSocket( "127.0.0.1:8999", 10 ); #use IP sockets
$socket = FCGI::OpenSocket( "/usr/local/webserver/nginx/perl_cgi-dispatch.sock", 10 ); #use UNIX sockets - user running this script must have w access to the 'nginx' folder!!
$request = FCGI::Request( \*STDIN, \*STDOUT, \*STDERR, \%req_params, $socket );
if ($request) { request_loop()};
FCGI::CloseSocket( $socket );
}
sub request_loop {
while( $request->Accept() >= 0 ) {
#processing any STDIN input from WebServer (for CGI-POST actions)
$stdin_passthrough ='';
$req_len = 0;
$req_params{'CONTENT_LENGTH'};
if (($req_params{'REQUEST_METHOD'} eq 'POST') && ($req_len != 0) ){
my $bytes_read = 0;
while ($bytes_read < $req_len) {
my $data = '';
my $bytes = read(STDIN, $data, ($req_len - $bytes_read));
last if ($bytes == 0 || !defined($bytes));
$stdin_passthrough .= $data;
$bytes_read = $bytes;
}
}
#running the cgi app
if ( (-x $req_params{SCRIPT_FILENAME}) && #can I execute this?
(-s $req_params{SCRIPT_FILENAME}) && #Is this file empty?
(-r $req_params{SCRIPT_FILENAME}) #can I read this file?
){
pipe(CHILD_RD, PARENT_WR);
my $pid = open(KID_TO_READ, "-|");
unless(defined($pid)) {
print("Content-type: text/plain\r\n\r\n");
print "Error: CGI app returned no output - Executing $req_params{SCRIPT_FILENAME} failed !\n";
next;
}
if ($pid > 0) {
close(CHILD_RD);
print PARENT_WR $stdin_passthrough;
close(PARENT_WR);
while(my $s = <KID_TO_READ>) { print $s; }
close KID_TO_READ;
waitpid($pid, 0);
} else {
foreach $key ( keys %req_params){
$ENV{$key} = $req_params{$key};
}
# cd to the script's local directory
if ($req_params{SCRIPT_FILENAME} =~ /^(.*)\/[^\/] $/) {
chdir $1;
}
close(PARENT_WR);
close(STDIN);
#fcntl(CHILD_RD, F_DUPFD, 0);
syscall(&SYS_dup2, fileno(CHILD_RD), 0);
#open(STDIN, "<&CHILD_RD");
exec($req_params{SCRIPT_FILENAME});
die("exec failed");
}
}
else {
print("Content-type: text/plain\r\n\r\n");
print "Error: No such CGI app - $req_params{SCRIPT_FILENAME} may not exist or is not executable by this process.\n";
}
}
}
---------------------------------------------------------------------------------------------------------------------------------------------------------------------
注意: 将 $socket = FCGI::OpenSocket( "/usr/local/webserver/nginx/perl_cgi-dispatch.sock", 10 ); 中的地址改成你自己的地址
保存完毕后
赋予 perl-fastcgi.pl 执行权限 chmod x perl-fastcgi.pl
并运行文件，运行后将会生成 perl_cgi-dispatch.sock 文件。
------------------------------------------------------------------------------------------------------------------------------------------------------------------------
3. 修改nginx的配置文件 nginx.conf 在配置文件中 增加 location 支持Cgi 的文件
--------------------------------------------------------------------------------------------------------------------------
location ~ \.cgi$
{
fastcgi_pass unix:/usr/local/webserver/nginx/perl_cgi-dispatch.sock;
fastcgi_index index.cgi;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
----------------------------------------------------------------------------------------------------------------------------
保存完毕后 然后重启 Nginx 之后
建一个 CGI文件测试一下
----------------------------------------------------
#!/usr/bin/perl
print "Content-type: text/html\n\n";
print "Hello, world.";
-----------------------------------------------------
