Nginx Cache Server Setup

This document is a guide for setting up Nginx-DLB benchmark environment, including Hardware platform and Software configuration on storage.

HW Prerequisites

• Setup 3 servers: one node (client) for client deployment; 2 node for cache server (worker-0) and content server (worker-1) deployment.
• Cache server (worker-0) requires 5 NVMe disks.

K8S Labels configuaration

Please finish the section, Storage configuration, then label the corresponding nodes.

Command examples:

• Label:

  kubectl label node <node name> HAS-SETUP-NVMECACHE=yes
  

• Unlabel:

  kubectl label node <node name> HAS-SETUP-NVMECACHE-
  

Nginx cache server worker-0:*

• HAS-SETUP-NGINX-CACHE=yes

Storage configuration

This should be done on worker-0.

• Prepare 5 nvme disk for nginx cache server pod. nvme? means multiple nvme disk.

• Check NVMe drives and Partition drives ```shell command ls /dev/nvme*

  ```output
  /dev/nvme1    /dev/nvme2    /dev/nvme3    /dev/nvme4    /dev/nvme5
  

• Format drives as ext4 (or xfs): shell command mkfs.ext4 /dev/nvme1n1 mkfs.ext4 /dev/nvme2n1 mkfs.ext4 /dev/nvme3n1 mkfs.ext4 /dev/nvme4n1 mkfs.ext4 /dev/nvme5n1

• Create cache mountpoints and mount to four pairs shell command mkdir /nginx/cache1 mount -o rw,noatime,seclabel,discard /dev/nvme1n1 /nginx/cache1 mkdir /nginx/cache2 mount -o rw,noatime,seclabel,discard /dev/nvme2n1 /nginx/cache2 mkdir /nginx/cache3 mount -o rw,noatime,seclabel,discard /dev/nvme3n1 /nginx/cache3 mkdir /nginx/cache4 mount -o rw,noatime,seclabel,discard /dev/nvme4n1 /nginx/cache4 mkdir /nginx/cache5 mount -o rw,noatime,seclabel,discard /dev/nvme5n1 /nginx/cache5
