    In your script you have

     

    #!/usr/bin/env perl

    at the top. While this is legal from the shell it might be causing problems running as CGI. I would change it to just reference perl and see if that buys you anything.

    Sorry, but there isn't anything about Apache that is simple. I can confirm that if you put your "printenv" file in /Library/WebServer/CGI-Executables and make it world executable, it does what it is supposed to. How are you referring to it in your web browser? In the default Apple configuration, I just have to go to http://localhost/cgi-bin/printenv

     

    Are you doing something similar? Keep in mind that your "default" configuration is default from Apache and few, if any Mac users run with that configuration. We use Apple's configuration that uses different values for just about everything. These "default" cofiguration are pretty misleading to begin with. Apart from a few demo scripts, few people run with anything close to default settings.

    Thanks for hanging in there with me.

     

    I thought about whether the shebang line was incorrect, and I tried several different ones, including these two:

     

    /usr/bin$ which -a perl

    /Users/7stud/perl5/perlbrew/perls/perl-5.16.0/bin/perl

    /usr/bin/perl

     

    >Sorry, but there isn't anything about Apache that is simple.<

     

    While I agree, I'm not new to Apache and cgi scripting.  I was setting up Apache, php, mysql from source on Windows back in 2002, and I was always able to get things working. 

     

    >How are you referring to it in your web browser?<

     

    I posted the url I was using in my original cgi post:

     

    http://localhost:8080/cgi-bin/printenv

    Hurray, I got cgi to work.

     

     

    The ScriptAlias line, which is supposed to enable cgi scripts to execute, is inside a pair of <IfModule> tags:

     

     

    <IfModule alias_module>

        …

        …

     

     

        ScriptAlias /cgi-bin/ "/usr/local/apache2/cgi-bin/"

     

     

    </IfModule>

     

    So I searched the apache docs for info on what an <IfModule> tag does:

     

     

    http://httpd.apache.org/docs/2.2/mod/core.html#ifmodule

     

     

    The docs say the lines inside the tag are only executed if the test is true, which in this case means that alias_module exists.  What the heck is an alias module, and how do I know if it exists?  So, I searched my httpd.conf for 'alias_module', and I found this line:

     

     

    LoadModule alias_module modules/mod_alias.so

     

     

    As a result, I concluded that apache loads alias_module, and therefore the stuff inside the <IfModule alias_module> tag does in fact execute. 

     

    So how come the ScriptAlias line isn't allowing my cgi scripts to execute?  Next, I hit up the apache docs for 'ScriptAlias':

     

     

    http://httpd.apache.org/docs/2.2/mod/mod_alias.html#scriptalias

     

     

     

     

    The ScriptAlias directive has the same behavior as the Alias directive, except that in addition it marks the target directory as containing CGI scripts that will be processed by mod_cgi's cgi-script handler.

     

     

    Hmmm…something called a mod_cgi. Let's search httpd.conf for 'mod_cgi':

     

     

    #LoadModule cgid_module modules/mod_cgid.so

     

     

    Hmmm...not an exact match.  I wonder what will happen if I uncomment that line?  So I uncommented that line.  (By the way to change httpd.conf, I had to use:

     

     

    $ sudo mvim httpd.conf  (I'm using the macvim version of vim for text editing.)

     

     

    Otherwise, I got a 'read only error'. )

     

     

    Then I restarted apache,

     

    $ sudo /usr/local/apache2/bin/apachectl -k stop

    $ sudo /usr/local/apache2/bin/apachectl -k start

     

    and voila! the results of the printenv test script were displayed in my browser.  I decided to check into what mod_cgid is, and I found this:

     

    Summary

    Except for the optimizations and the additional ScriptSock directive noted below, mod_cgid behaves similarly to mod_cgi. See the mod_cgi summary for additional details about Apache and CGI.


    On certain unix operating systems, forking a process from a multi-threaded server is a very expensive operation because the new process will replicate all the threads of the parent process. In order to avoid incurring this expense on each CGI invocation,mod_cgid creates an external daemon that is responsible for forking child processes to run CGI scripts. The main server communicates with this daemon using a unix domain socket.

     

    This module is used by default instead of mod_cgi whenever a multi-threaded MPM is selected during the compilation process. At the user level, this module is identical in configuration and operation to mod_cgi. The only exception is the additional directive ScriptSock which gives the name of the socket to use for communication with the cgi daemon.

     

    http://httpd.apache.org/docs/2.2/mod/mod_cgid.html

     

     

     

     

     

    I was able to use the shebang:

     

     

    #!/usr/bin/env perl

     

     

     

    And if you want the html in a test script to be rendered as html, use the line:

     

     

    print "Content-type: text/html; charset=iso-8859-1\n\n";

     

     

    rather than 'text/plain'.

    Example httpd.conf for Mac OSX 10.6.8:

    #

    # This is the main Apache HTTP server configuration file.  It contains the

    # configuration directives that give the server its instructions.

    # See <URL:http://httpd.apache.org/docs/2.4/> for detailed information.

    # In particular, see

    # <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>

    # for a discussion of each configuration directive.

    #

    # Do NOT simply read the instructions in here without understanding

    # what they do.  They're here only as hints or reminders.  If you are unsure

    # consult the online docs. You have been warned. 

    #

    # Configuration and logfile names: If the filenames you specify for many

    # of the server's control files begin with "/" (or "drive:/" for Win32), the

    # server will use that explicit path.  If the filenames do *not* begin

    # with "/", the value of ServerRoot is prepended -- so "logs/access_log"

    # with ServerRoot set to "/usr/local/apache2" will be interpreted by the

    # server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log"

    # will be interpreted as '/logs/access_log'.

     

     

    #

    # ServerRoot: The top of the directory tree under which the server's

    # configuration, error, and log files are kept.

    #

    # Do not add a slash at the end of the directory path.  If you point

    # ServerRoot at a non-local disk, be sure to specify a local disk on the

    # Mutex directive, if file-based mutexes are used.  If you wish to share the

    # same ServerRoot for multiple httpd daemons, you will need to change at

    # least PidFile.

    #

    ServerRoot "/usr/local/apache2"

     

     

    #

    # Mutex: Allows you to set the mutex mechanism and mutex file directory

    # for individual mutexes, or change the global defaults

    #

    # Uncomment and change the directory if mutexes are file-based and the default

    # mutex file directory is not on a local disk or is not appropriate for some

    # other reason.

    #

    # Mutex default:logs

     

     

    #

    # Listen: Allows you to bind Apache to specific IP addresses and/or

    # ports, instead of the default. See also the <VirtualHost>

    # directive.

    #

    # Change this to Listen on specific IP addresses as shown below to

    # prevent Apache from glomming onto all bound IP addresses.

    #

    #Listen 12.34.56.78:80

    Now, you guys are assuring me that there is no security risk by turning Sharing on if I want to use php, etc. in the future?

    There is always some security risk involved with running a server. That risk is virtually zero in this case.

  • 22. Re: Installing Apache 2.4.3 on OSX 10.6.8

    I decided to try and install php from source--just to see if I could do it.  After messing around with vagrant unsuccessfully, I decided vagrant was way too complicated, and I installed php from source myself.  In case anyone else is interested in how I installed php, I followed the php install instructions here (which are the Unix install instructions, which the Mac Install Instructions said to use):

     

    http://www.php.net/manual/en/install.unix.apache2.php

     

    Here are some clarifications of some of the steps:

     

    3) I ignored step 3 (because I had already installed apache):

     

    Build and install Apache. Consult the Apache install documentation for more details on building Apache.

     

     

    cd httpd-2_x_NN

    ./configure --enable-so

    make

    make install

     

    Apparently the apache install does the --enable-so by default.

     

     

    5) I had previously installed mysql, and the --with-mysql flag, succeeded in allowing me to access my databases from a php script.

     

     

    6) Make sure you do step 6:

     

     

    cp php.ini-development /usr/local/lib/php.ini

     

    I guess by default php reads the php.ini file located at /usr/local/lib/ and there isn't one there until you copy it.

     

    7) The php install took care of adding the specified line to apache's http.conf.

     

     

    8) I added the following to http.conf:

     

     

    <FilesMatch \.php$>

        SetHandler application/x-httpd-php

    </FilesMatch>

     

     

     

    9)  To test your php install, start apache then create a file called my_test.php containing the following:

     

     

    <!DOCTYPE html>

    <html>

    <body>

     

     

    <?php

    echo "My first PHP script!";

    phpinfo();

    ?>

     

     

    </body>

    </html>

     

     

    Put that file in the directory /usr/local/apache2/htdocs.  Then use the following url in your browser:

     

     

    http//localhost:8080/my_test.php

     

     

    (Note that in apache's httpd.conf file, I have this line:

     

     

    Listen 8080

     

     

    which makes apache listen on port 8080, which means I have to include the port in the url.)

     

     

    If you scroll down the resulting page, you can see lots of php/mysql/apache configuration info.
