WebMO Help - Installing WebMO on Mac OS X

Installation Instructions for Mac OS X

These instructions are for installing a copy of WebMO the first time. To upgrade an existing WebMO configuration, refer to the WebMO upgrade instructions instead.

  1. Obtain a WebMO license.
  2. Download "WebMO for Linux/Mac" to your Mac. The WebMO.*.tar.gz distribution will automatically be expanded into a WebMO.*.tar file.
  3. Configure OS X webserver.
    1. Turn on the Apache web server
      Start a terminal session (Applications/Utilities), and type:
      $ sudo apachectl start
      To insure that apache starts automatically on boot, type:
      $ sudo launchctl load -w /System/Library/LaunchDaemons/org.apache.httpd.plist
      or in older versions of OS X, one can type:
      $ sudo defaults write /System/Library/LaunchDaemons/org.apache.httpd Disabled -bool false
    2. Configure Apache
      Edit the file: /etc/apache2/httpd.conf
              Uncomment the line 'Include /private/etc/apache2/extra/httpd-userdir.conf'
              Uncomment the line 'LoadModule userdir_module libexec/apache2/mod_userdir.so'
              Uncomment the line 'LoadModule cgi_module libexec/apache2/mod_cgi.so'
      Edit the file: /etc/apache2/extra/httpd-userdir.conf
              Uncomment the line: 'Include /private/etc/apache2/users/*.conf'
    3. Configure Apache for WebMO
      Determine your home directory
      $ echo $HOME

      Create a HTML directory (if necessary)
      $ mkdir /Users/smith/Sites
      Create CGI directory
      $ mkdir /Users/smith/Sites/cgi-bin
      Move into apache configuration directory
      $ cd /etc/apache2/users
      Define CGI directory
      $ sudo vi smith.conf
      {enter administrative password}
      i {to enter insert mode}
      <Directory "/Users/smith/Sites/">
          AllowOverride All
          Options Indexes MultiViews FollowSymLinks
          Require all granted
      ScriptAlias /~smith/cgi-bin/ "/Users/smith/Sites/cgi-bin/"

      {esc}:wq {to exit insert mode, save file, and exit vi}
    4. (Additional step for Mac OS X Server ONLY)
      Edit the file: /Library/Server/Web/Config/apache2/httpd_server_app.conf
              Uncomment the line 'Include /private/etc/apache2/extra/httpd-userdir.conf'
              Uncomment the line 'LoadModule apple_userdir_module...'
    5. Restart Apache
      $ sudo apachectl restart
  4. Untar the WebMO distribution
    $ cd {download directory} $ tar xf WebMO..x.xxx.tar
  5. Run the setup script
    $ cd WebMO.install
    $ perl setup.pl
