How to Rebuild corrupted userdata files in Cpanel

In certain circumstances , your servers user data files may corrupt which can create issues while migrating , operating the cpanel accounts. These user data files can be repaired using a  valid and working httpd.conf  file on the server.

Lets assume we have a corrupted user data file , in order to rebuild the user data file follow the steps as below.

  1. Login to your WHM/Cpanel server with root user
  2. The user data files are located at /var/cpanel. Make sure if the userdata directory is present on the server.
  3. If the directory exists , move it or rename it with mv command

    mv /var/cpanel/userdata /var/cpanel/userdata_backup

  1. Create a new user data directory with the command mkdir

    mkdir /var/cpanel/userdata

  1. Now that we have a new userdata directory created , in order to rebuild userdata files for all the accounts hosted on your cpanel server run the script “userdata_update” with “–reset” flag which will rebuild the userdata files for all the accounts that are hosted on your cpanel server.

    /usr/local/cpanel/bin/userdata_update –reset

  1. The next step will be to fix the permissions for newly generated user data files which can be done by running the command

    /usr/local/cpanel/bin/fix_userdata_perms

  1. Since we have a new userdata file generated we will need to update the system’s cache which can be done by command

    /scripts/updateuserdatacache

  1. Now rebuild the apache configuration in order to use the newly rebuilt userdata files with the command

    /scripts/rebuildhttpdconf

  1. Restart the apache service with the command

    /scripts/restartsrv_httpd
