This is good enough when you just want to try things out and want to have as few obstacles as possible. Once you understand how things work, you should tighten the permissions of files served by Apache. In future articles we will talk about setting proper file permissions.
As you probably know, mod_perl allows you to reuse CGI scripts written in Perl that were previously used under mod_cgi. Therefore our first test script can be as simple as:
mod_perl_rules1.pl ------------------ print "Content-type: text/plain\r\n\r\n"; print "mod_perl rules!\n";
Save this script in the
file. Notice that the
shebang line is not needed with mod_perl,
but you can keep it if you want. So the following script can be used as well:
mod_perl_rules1.pl ------------------ #!/usr/bin/perl print "Content-type: text/plain\r\n\r\n"; print "mod_perl rules!\n";
Of course you can write the same script using the Apache Perl API:
mod_perl_rules2.pl ------------------ my = shift; ->send_http_header('text/plain'); ->print("mod_perl rules!\n");
Save this script in the /home/httpd/perl/mod_perl_rules2.pl file.
Now make both of the scripts executable and readable by the server. Remember that when you execute scripts from a shell, they are being executed by the user-name you are logged with. When instead you try to run the scripts by issuing requests, Apache needs to be able to read and execute them. Apache is running under a user-name specified by the
Userdirective. If the server is running under user-name nobody, the following will do:% chown nobody /home/httpd/perl/mod_perl_rules1.pl /home/httpd/perl/mod_perl_rules2.pl % chmod 0755 /home/httpd/perl/mod_perl_rules1.pl /home/httpd/perl/mod_perl_rules2.pl
The first command makes the files belong to user nobody, the second sets the proper execution and read permissions.
You can test
mod_perl_rules1.plfrom the command line, since it is essentially a regular Perl script:% perl /home/httpd/perl/mod_perl_rules1.pl
You should see the following output:
You cannot test the second script by executing it from the command line since it uses the mod_perl API which is available only when run from within the mod_perl server.
Make sure the server is running and issue these requests using your favorite browser:
In both cases you will see on the following response:mod_perl rules!
If you see it--congratulations! You have a working mod_perl server.
If you're using port 8080 instead of 80, you should use this number in the URL:
