How to change the default index for all websites on Plesk?

Note: In the following example, index.php is set as a priority. All newly created domains will have the new directoryIndex afterwards.

1. Connect to the server via SSH;

2. Add the following lines to /usr/local/psa/admin/conf/panel.ini using any text editor:

   [webserver]
   directoryIndex = "index.php index.html index.cgi index.pl index.xhtml index.htm index.shtml"

3. Reconfigure all existing domains:

   # plesk bin domain -l | while read i; do plesk repair web $i -y; done

Note: In the following example test.php file is set as a priority:

1. Connect to the server via RDP.

2. Open PowerShell command line

3. Run one of the following commands depending on the requirements:

   • Set up the "test.php" file as a default document file for all existing domains:

     Note: change the "test.php" file in the command below to the correct one.

     PS > plesk bin site -l | % { if ( $_ ) { &$env:windirsystem32inetsrvappcmd.exe set config $_ /section:defaultDocument /enabled:true /+files.[value=`'test.php`'] } }

   • If the following error appears:

     ERROR ( message:New add object missing required attributes. Cannot add duplicate collection entry of type 'add' with unique key attribute 'value' set to 'main.php'. )

     then such file is already present in the default documents list. Modify file priority manually in IIS > hostname > Sites > example.com > Default Documents.
     

   • Reset the customization of Default Documents to default for all domains:

     PS > plesk bin site -l | % { if ( $_ ) { &$env:windirsystem32inetsrvappcmd.exe clear config $_ /section:defaultDocument } }
