ArcGIS Server account

ArcGIS Server starts and stops processes, reads and writes data to locations on the file system, and communicates between machines. To do these things securely, it uses an operating system account that you specify when you install ArcGIS Server. This is known throughout the documentation as the ArcGIS Server account.

When the ArcGIS Server account is used

The ArcGIS Server account is used for the following purposes:

  • Start and stop processes that support ArcGIS Server and services.
  • Read the GIS data behind your services when the registered database uses operating system authentication.
  • Read and write files to the ArcGIS Server directories. For example, when you create a map cache, the ArcGIS Server account writes the cache tiles into your server cache directory.
  • Read and write files to the configuration store.
  • Read and write files to the ArcGIS Server installation location and system temp directory. For example, the account writes log files that you can use to troubleshoot the server.
  • Read and write log messages to the logs directory.

The ArcGIS Server account is not the same as the primary site administrator that you define when you create the ArcGIS Server site. For more information, see Secure your ArcGIS Server site.

Which account is the ArcGIS Server account

The ArcGIS Server account is the one you used when you installed the software. The installation makes this account the owner of all files that it places on the system. In a site with multiple ArcGIS Server machines, the user ID (UID) for the ArcGIS Server account should be the same across all machines so that they can access data, the configuration store, and the server directories using the same NFS permissions.

For security reasons, the root account cannot be used as the ArcGIS Server account and cannot be used to install the software.

Permissions to grant to the ArcGIS Server account

The ArcGIS Server account requires no special permissions on the operating system other than file access to the data, configuration store, and server directories. The ArcGIS Server account does not need to be an administrator on the machine.
