Settings > Hosts > General

MAMP PRO uses virtual hosts to allow your web servers to serve different websites. The “localhost” virtual host is created by default and cannot be deleted. You can add an unlimited number of hosts, allowing you to create one host per project. Each host can have it’s own directory to store html, PHP files and images. This directory is called the Document Root.

The name of a host (server name) must be unique, often it’s convenient to use a reverse domain naming scheme to easily identify it (e.g. use info.mamp.development instead of The unreversed name may conflict with an external domain name.

To create a new host, press the “Plus” button in the lower left corner of the hosts table.


  • Host Name

    The server name and port number must be unique within MAMP PRO. The host name can only contain letters and/or numbers and dashes (“-“), but cannot begin or end with a “-“ character. Names are not case sensitive (upper and lower case are not distinguished).

  • Document root

    The location of a virtual host’s documents (HTML/PHP files, etc.) is called the document root. The document root is also known as the web root folder. MAMP PRO will automatically add an index.php file and a MAMP image to this location when your web server is restarted if the folder is empty.

  • Create a database named

    You may optionally create a MySQL database. Most content management systems require a database, and you can conveniently add one here.

  • Copy the contents of a template folder to the document root

    You can optionally add the contents of a templates folder. You may use the same template, js, and css files/folders in every site you develop. Use this option to copy the contents of your template folder to your new document root folder.


  • Hosts Table

    The hosts table has five columns. The first column contains your host name. The second column indicates which web server is hosting the file.

    The third column indicates whether the host is active. If left unchecked, the host will not be active and cannot be viewed in a web browser.

    The fourth column contains the PHP version that is used with host. The fifth column will display an icon of the Extra installed if an Extra is installed.

  • Hostname
    The server name and port number in combination must be unique within MAMP PRO. The host name may only contain letters and/or numbers, as well as dashes (“-“); but it may not begin or end with a “-“ character. Names are not case-sensitive.

    If the servers are running you can use the Open button to open a host in your web browser.

  • IP address
    If this field is left empty or contains an * the web server will use one of the computer’s IP addresses to access this host. If you want to choose which of the IP addresses should be associated with a host, then select it from the pop up menu.

  • Port number
    Determine the port with which the virtual host is accessible. Valid values are from 1 to 65535. In most cases the preset value does not need to be changed.

  • PHP Version
    Determine which version of PHP a host will use. This can only be set when Individual PHP version for every host (CGI) is set in the PHP section of MAMP PRO.

    If you select the default PHP version MAMP PRO will automatically adapt this setting if you choose a new default version in the PHP tab. Use a fixed setting to tell MAMP PRO not to alter the PHP version.


    Sounds complicated? Let’s take a look at an example: The default version is set to 5.5.9. You have oneHost set to PHP version “Default (5.5.9)”, anotherHost set to “5.5.9” and yetAnotherHost set to “5.3.28”. If you set the PHP version in the PHP section to “5.4.25”, MAMP PRO will adapt the PHP version of oneHost to this version (it is set to always use the standard version). The other 2 hosts will not be changed.

    • PHPInfo


      View your PHP configuration by pressing the “i” button to the right of the version name.

  • Dynamic DNS
    Determines, if this virtual host is accessible with the Dynamic DNS service from the internet.

  • Use with server
    Determine which web server will be used with your host. An icon next to the server name in the server list will also indicate which web server you chose.

  • Name resolution
    This will determine how your system will map host names to ip addresses.

    • via hosts file
      The basic mapping mechanism which uses the the file “C:\Windows\System32\drivers\etc\hosts”.

    • for “MAMP Viewer” (LAN only)
      Enable your host to be viewed on the MAMP Viewer.

    • via (LAN only)
      Allow other computers on your local network to access your web site. Using the Share button you can send the address to other users.

      Note: The addresses will only work in your local network. They are temporary and may become invalid if you restart your PC. Also make sure that your Internet router is not blocking calls by using a DNS Rebind protection. If the router does this you can either deactivate this function, add as an exception or not use the router as DNS Server in your PCs network settings.

  • Document root
    The location of the documents (HTML/PHP files etc.) of a virtual host is called a document root.

  • Alias Name
    Aliases are additional names for your virtual host. The same constraints apply to these additional names as to the host itself. Add aliases with the plus-button.

To remove a new host press the “Minus” button at the bottom left of the screen.


  • Delete document root folder

    MAMP PRO will delete your document root folder and all of its contents.

  • Remove the databases of the installed Extras

    If your host is an Extra, MAMP PRO will delete the database installed Extra database.
