Operating system requirements
Firewall configuration
When deploying a Doris cluster on Kubernetes, it is recommended to turn off the firewall configuration:
systemctl stop firewalld
systemctl disable firewalld
If the firewall service cannot be turned off, you can open the FE and BE ports according to your plan:
If the firewall cannot be turned off, you need to open the firewall of the corresponding Doris port according to the Kubernetes mapping rules. For specific ports, please refer to [Doris Cluster Port Planning](/docs/3.0/install/cluster-deployment/standard-deployment#Network Requirements).
Disable and close swap
When deploying Doris, it is recommended to turn off the swap partition.
The swap partition can be permanently shut down with the following command.
echo "vm.swappiness = 0">> /etc/sysctl.conf
swapoff -a && swapon -a
sysctl -p
Set the maximum number of open file handles in the system
vi /etc/security/limits.conf
* soft nofile 65536
* hard nofile 65536
Modify the number of virtual memory areas
Modify the virtual memory area to at least 2000000
sysctl -w vm.max_map_count=2000000
Close transparent large page
When deploying Doris, it is recommended to turn off transparent huge pages.
echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag
