Set up hosts for the ThoughtSpot cluster
Set up hosts for the ThoughtSpot cluster on your chosen platform. Please refer to the relevant deployment sections in our documentation for the exact specification for the hosts: CPU, memory, and disks.
- [RHEL only] ThoughtSpot-certified hardware appliance manufactured by DELL
- [RHEL only] ThoughtSpot-certified hardware appliance manufactured by SMC
- Amazon Web Services (AWS) EC2
- Google Cloud Platform (GCP)
- [RHEL only] Microsoft Azure
Partition the hosts
Ensure that all ThoughtSpot hosts meet the following partition and sizing requirements. All drives must be SSDs.
At least 20 GB available on the root drive, for yum packages and system logs.
At least 50 GB available for
At least 200 GB for ThoughtSpot installation, either on a secondary drive or as a separate partition on the root drive. For ThoughtSpot-certified hardware platforms, Dell and Super Micro Computer, you must use a secondary drive, since the root drive has a limit of 200 GB.Note: This drive must be separate from the data drive(s).
Install RHEL or OEL on hosts
ThoughtSpot is certified with RHEL versions 7.8 and 7.9; we do not support other versions of RHEL, including 7.7, 8, and 8.1. ThoughtSpot is certified with OEL version 7.9. Install RHEL version 7.8 or 7.9 or OEL version 7.9. On RHEL version 7.8, ensure that your linux kernel version is 3.10.0-1127.19.1. On RHEL version 7.9, use the default linux kernel. On OEL version 7.9, ensure that you are using the Red Hat Compatible Kernel (RHCK), not the default Unbreakable Enterprise Kernel (UEK). If you are using the UEK, contact ThoughtSpot Support to switch to the RHCK.
Linux kernel version
For RHEL version 7.8, your Linux kernel must be on version 3.10.0-1127.19.1. RHEL 7.8 used to come with a Linux kernel of version 3.10.x, which has a bug that causes nodes to reboot unexpectedly. The default Linux kernel version for RHEL 7.8 is now 3.10.0-1127.19.1. However, you may have an older RHEL 7.8, with a Linux kernel of version 3.10.x. You must upgrade to 3.10.0-1127.19.1. If you have trouble upgrading your Linux kernel to version 3.10.0-1127.19.1, contact ThoughtSpot Support. This is a requirement for all platforms: appliance, cloud, and VMware.
If you are using RHEL version 7.9, use the default Linux kernel.
On OEL version 7.9, ensure that you are using the Red Hat Compatible Kernel (RHCK), not the default Unbreakable Enterprise Kernel (UEK). If you are using the UEK, contact ThoughtSpot Support to switch to the RHCK.
Enable the hosts to download RHEL or OEL packages
- Yum repositories for RHEL:
For RHEL deployments, you must enable the following Yum repositories in your cluster:
- Yum repositories for OEL:
For OEL deployments, you must enable the following Yum repositories in your cluster:
- Python repository: for Python, ensure the machine is able to reach the
PyPIrepository located at https://pypi.python.org/.
- R repository: for R, ensure the machine is able to reach the
CRANrepository located at https://cran.rstudio.com/.
If you cannot access the RHEL or OEL repositories, there is no mirror repository in your organization, or you are unable to access Yum, Python, or R repositories, please contact ThoughtSpot Support.
Official package repositories
If the hosts of your ThoughtSpot cluster can access external repositories, either directly or through a proxy, your cluster is online. You can then proceed to download Yum, Python, and R package repositories.
Internal mirror repository
Enable an Ansible Control Server
Configure an Ansible Control Server, on a separate host, to run the Ansible playbook that ThoughtSpot supplies. You must install both
rsync and Ansible on the Ansible Control Server host.
Ensure tmp has permission 777
/tmp directory must have the
Remove Defaults requiretty from /etc/sudoers
/etc/sudoers file must not have the
Defaults requiretty line. This line can cause cluster creation to fail.
