Manual: Multi-node HA-ready production profile requirements and installation
This page walks you through the requirements and installation instructions for the multi-node HA-ready production profile.
Linux and Kubernetes knowledge is required regardless of the deployment profile you choose. If you encounter issues installing and configuring Automation Suite, contact UiPath Professional Services.
Before choosing your deployment profile, see Supported use cases for single-node and multi-node installations.
The installation process generates self-signed certificates on your behalf. These certificates will expire in 90 days, and you must replace them with certificates signed by a trusted Certificate Authority (CA) as soon as installation completes. If you do not update the certificates, the installation will stop working after 90 days. For instructions, see Managing certificates.
The multi-node HA-ready production profile is resilient to only one node failure. This means that you can lose only one server node. This restriction does not apply to agent nodes. You can lose as many agent nodes and still continue to use the cluster without downtime as long as enough overall cluster capacity is available.
Federal Information Processing Standard (FIPS) is not compatible with Automation Suite. If FIPs is enabled at any point on the servers running Automation Suite, the cluster will fail. If FIPs is enabled on any cluster server, the installer will encounter issues blocking the installation.
Larger node sizes are more efficient than smaller node sizes because of the fixed baseline resource overhead per node. For example, 3 x 32 cores nodes is more efficient than 6 x 16 cores nodes.

RHEL kernel version kernel-4.18.0-477.10.1.el8_8 is affected by an issue that interrupts the installation or management of the Automation Suite cluster. Make sure that none of the Automation Suite nodes uses this kernel version either pre- or post-installation. You can update the kernel version by running the following command:
dnf install -y kernel kernel-tools kernel-tools-libs
dnf install -y kernel kernel-tools kernel-tools-libs
- You need root permission to install and deploy Automation Suite. For more on the specific components that require root access, see Root privileges requirement.
-
Cilium requires CAP_SYS_ADMIN permissions to function correctly. Make sure these permissions are granted.
- Having scan agents running on your system may cause installation or runtime failures, due to the changes they make to the IPTables. To avoid this behavior, configure your scan agent so that it does not interfere with the Automation Suite installation.
- UiPath does not prescribe specific firewall or developer tool configurations as long as the Automation Suite requirements are met. Based on our observations, a limited number of external tools can interfere with the smooth operation of Automation Suite. If such issues arise, contact the relevant vendor for help. For additional guidance, see the Automation Suite responsibility matrix.
The minimum hardware requirements do not protect the deployment from node failures.
To understand your storage needs and plan for them accordingly, see Evaluating your storage needs.
