ArcGIS Server 10.5.x system requirements

The system and hardware requirements to run ArcGIS Server are listed below. A diagnostics tool runs during the setup to help you determine if your machine meets the minimum system requirements. For information about earlier versions, see Esri Support.

It's recommended that you review the deprecation notice to determine if your hardware and software components are still compatible with version 10.5.1.

Operating system requirements

The following 64-bit operating systems satisfy the minimum operating system requirements. Support is not provided for 32-bit operating systems; the setup will only proceed if the operating system is 64-bit. ArcGIS Server is only supported on Linux x86_64, on CPUs that adhere to the x86_64 architecture (64-bit), with supported Linux releases.

Machines with an underscore (_) in the name are not supported. The setup will not proceed if an underscore is detected in the machine name.

You cannot install the software as a root user. If you attempt to do this, the installation will not proceed and a software diagnostics tool will display an error message indicating that you cannot install as root.

Esri Technical Support is available for CentOS, Scientific Linux, and Oracle Linux versions that provide full binary compatibility with an equivalent supported Red Hat version. As a prerequisite for logging a defect, any software issue on these operating systems will be attempted to be reproduced on Red Hat Enterprise Linux. For Oracle Linux, support is predicated on the use of the Red Hat compatible kernel.


If you want to install the software, run the ArcGIS Software Authorization Wizard, or run the Check for Updates tool using the operating system graphical user interface (GUI), the X Window System package group is required.

The following package groups are required.

Red Hat Enterprise Linux Server requirements

Red Hat Enterprise Linux Server 6 and 7

  • gettext
  • libXtst (ArcGIS 10.5 only)

SUSE Linux Enterprise Server

SUSE Linux Enterprise Server 11 and 12

  • gettext-runtime
  • libXtst (ArcGIS 10.5 only)

Ubuntu Server LTS

Ubuntu Server 16.04 LTS

  • gettext-base
  • libxtst6 (ArcGIS 10.5 only)

Hardware requirements

OpenGL version 1.5 or later is required.

The minimum RAM requirement for GIS Server, ArcGIS GeoEvent Server, ArcGIS Image Server, or Esri Business Analyst for Server: 8 GB per unique license role.

For a production environment, minimum hardware requirements are not listed because the user and business needs of the software may vary. These requirements must be considered in determining hardware needs to meet performance and scalability expectations.

ArcGIS GeoAnalytics Server: 16 GB

When configuring ArcGIS GeoAnalytics Server, ensure that the drive hosting the \tmp directory has sufficient temporary space available. When determining a sufficient value, consider the input data size, the type of GeoAnalytics task, and the number of nodes in your site.

Example scenario:

Input data size: 100 GB of CSV point features

ArcGIS GeoAnalytics Server nodes: 5

Task: Join Features (self-join, simple Cartesian product of evenly distributed features)

Recommended space on disk: (100 x 100 GB) / 5 = 2 TB/node

Increment space accordingly to accommodate concurrent GeoAnalytics jobs.

ArcGIS Server requires a minimum of 10 GB of available disk space to successfully install on the target system. Approximately 1.5 GB of the required disk space is used during the installation of this product. This temporary disk use will be removed at the end of the installation.


You cannot install ArcGIS Server on a shared network directory (NFS mounted folder). The directory must be local on the target system.

Temp space requirements

By default, resources are extracted to the system /tmp directory. This directory must have read, write, and execute permissions enabled. If the required space is not available in the /tmp directory, the setup program will attempt to extract resources to the user's HOME directory. If the required space is not available in the user's HOME directory, the setup program will report an error indicating this problem. Optionally, you can specify an alternate temp location by setting the IATEMPDIR environment variable.

The /tmp directory is also used when publishing. When uploading service definition (SD) files through Server Manager, files equal to the size of the SD file are created in the /tmp directory. Files are not permanently stored, but deleted every hour. Ensure that the /tmp directory has sufficient space for individual SD files to be published in this manner.

Default file permissions

Due to security reasons, all permission types (read, write, and execute) for group and all users are turned off by default.

File handles and processes limits

ArcGIS Server is a data-intensive server product, and many of its data formats consist of hundreds of thousands of files. In heavily used systems, thousands or tens of thousands of files may be in use at any given time. If there are insufficient file handles and processes, requests may start failing randomly, leading to system downtime. The actual number of file handles and processes needed varies based on the data and the number of instances (threads/processes) running. Setting a file handle limit of 65,535 and a process limit of 25,059 will allow you to ensure that the system remains running.

There are soft and hard limits for file handles and processes on Linux. To determine the hard limits, use the ulimit -Hn -Hu (or limit -h descriptors if you're using csh) command. To determine the soft limits, use the ulimit -Sn -Su (or limit descriptors if you're using csh) command.

To increase the soft and hard limits, you'll need to edit the /etc/security/limits.conf file with superuser access. For example, you can add four lines in the file as follows:

<ArcGIS Server installation user> soft nofile 65535
<ArcGIS Server installation user> hard nofile 65535
<ArcGIS Server installation user> soft nproc 25059
<ArcGIS Server installation user> hard nproc 25059

After making this change, you'll need to log out and log back in with the particular user for the new values to take effect. To verify that the limits have been modified appropriately, use the ulimit -Hn -Hu and ulimit -Sn -Su commands as described above.

Firewall settings

ArcGIS Server communicates on ports 1098, 4000-4004, 6006, 6080, 6099, and 6443. You'll need to open these ports on your firewall before installing the software. For more information, see Ports used by ArcGIS Server.

DNS hostname entry

ArcGIS Server must be installed on a machine that has a domain name service (DNS) hostname entry. This may require the system administrators for the site to add an entry to a name server in their network and that this name server be listed in the /etc/resolv.conf configuration file on the system.

If you'll be federating your site with Portal for ArcGIS, it's recommended you configure your organization's DNS to include fully qualified domain name (FQDN) entries for each site you intend to federate with the portal. Portal for ArcGIS will request the FQDN of each site when you federate.

SSL certificates

ArcGIS Server comes pre-configured with a self-signed certificate, which allows the server to be initially tested and to help you quickly verify that your installation was successful. You must request a certificate from a trusted certificate authority (CA) and configure the server to use it. This could be a domain certificate issued by your organization or a CA-signed certificate.

Like ArcGIS Server, Portal for ArcGIS also comes with a pre-configured self-signed certificate. If you'll be federating your site with Portal for ArcGIS, you should request a certificate from a trusted CA and configure the portal to use it.

For more information, see Best practices for configuring a secure environment.

Supported web browsers

ArcGIS Server Manager requires one of the following web browsers to be installed:

  • Google Chrome
  • Mozilla Firefox
  • Microsoft Internet Explorer (version 9, 10, or 11)
  • Microsoft Edge

ArcGIS Server on cloud platforms

You can deploy ArcGIS Server in the cloud. Many organizations do this to increase performance and capacity without having to buy and configure new hardware. Cloud platforms allow you to add more capabilities to your ArcGIS Server deployment, including resizing computer capacity, automatically scaling capacity up and down according to conditions you define, automatically distributing application traffic across multiple instances for better performance, and much more.

Esri provides ArcGIS Server virtual machine images on two popular cloud platforms: Amazon Web Services and Microsoft Azure.


Esri Technical Support is available for Esri software on cloud platforms. However, Esri may not provide support for Amazon Web Services or Microsoft Azure machine images that have been modified beyond standard Esri or operating system updates. It's recommended that you do not modify the software released by Esri.

ArcGIS Server AMI for Linux is available on Ubuntu. Changes to the Esri-released AMI will be treated as changes on an unsupported system.

Supported virtualization environments

All components of ArcGIS Enterprise are fully supported on virtual environments as long as they run on supported platforms. When running third-party applications with ArcGIS Enterprise, such as relational databases, the application must also be supported in a virtual environment. Check the third-party vendor for its virtualization support.

The following virtualization environments are known to perform well with ArcGIS Enterprise:

  • VMware vSphere 5.5 and 6
  • Microsoft Hyper-V

For additional information, see Virtualization and ArcGIS Server.

Supported databases

See the following topics for information on databases supported with ArcGIS Server:

You cannot connect to SQL Server from ArcGIS Server on Linux.

Not all components of ArcGIS Server Workgroup are available on Linux; for example, you cannot install SQL Server Express to create a database server and workgroup geodatabases on Linux.
