Simple RKE2, Rancher and Longhorn Install

Learn how to install RKE2 (Kubernetes), and I will also demo how to install Rancher, Longhorn and other packages using Helm. Install Rancher Server, your central control plane, and create RKE2 clusters with ease using its user-friendly web interface. Pre-Req For RKE2 Server 1) Stop firewall systemctl disable --now ufw 2) Run updates and upgrade and install packages apt update apt install nfs-common open-iscsi -y apt upgrade -y 3) Automatic removal of unnecessary packages. apt autoremove -y RKE2 Server Installation 1) Install RKE2 server curl -sfL https://get.rke2.io | INSTALL_RKE2_TYPE=server sh - For specific RKE2 Server version curl -sfL https://get.rke2.io | INSTALL_RKE2_CHANNEL=v1.26 INSTALL_RKE2_TYPE=server sh - 2) Enable and start RKE2 Server service systemctl enable rke2-server.service systemctl start rke2-server.service Alternatively, you can do this, which does the same thing systemctl enable --now rke2-server.service 3) Check is RKE2 Server is running systemctl status rke2-server.service Setup Kubectl (on RKE2 Server) 1) Simlink all the things - kubectl ln -s $(find /var/lib/rancher/rke2/data/ -name kubectl) /usr/local/bin/kubectl Alternatively, you can do this, which download the binary rather than using simlink. But note that you are downloading specific version of kubectl. Getting it from the RKE2 Server is a better option (aka simlink) curl -L# https://dl.k8s.io/release/v1.24.0/bin... -o /usr/local/bin/kubectl chmod 755 /usr/local/bin/kubectl 2) Add kubectl conf export KUBECONFIG=/etc/rancher/rke2/rke2.yaml Permanent nano .bashrc export PATH=$PATH:/etc/rancher/rke2/rke2.yaml 3) Check if kubectl works kubectl get node -o wide To watch as you start the RKE2 agent use this command. kubectl get node -o wide -w Get RKE2 Server IP address And Token (on RKE2 Server) 1) Get server IP address and copy it somewhere ip addr | grep inet 2) Get server token and copy it somewhere cat /var/lib/rancher/rke2/server/node-token Pre-Req For RKE2 Agents 1) Stop the software firewall systemctl disable --now ufw 2) Run updates and upgrade and install nfs apt update apt install nfs-common -y open-iscsi apt upgrade -y This is require for Longhorn iscsiadm --version 3) Remove downloaded update apt autoremove -y RKE2 Agent Installation 1) Install RKE2 agent curl -sfL https://get.rke2.io | INSTALL_RKE2_TYPE=agent sh - For specific RKE2 Server version curl -sfL https://get.rke2.io | INSTALL_RKE2_CHANNEL=v1.26 INSTALL_RKE2_TYPE=agent sh - 2) Create config directory mkdir -p /etc/rancher/rke2/ 3) Create config.yaml file for RKE2 agent nano /etc/rancher/rke2/config.yaml Enter text shown below. server: https://#RKE2_SERVER_IP_ADDRESS#:9345 token: #TOKEN_FROM_RKE2_SERVER# The #RANCHER_SERVER_IP_ADDRESS# is the ip address of RKE2 Server Install - Step 5 The #TOKEN_FROM_RANCHER_SERVER# is the ip address of RKE2 Server Install - Step 6 4) Enable and start RKE2 Agent service systemctl enable rke2-agent.service systemctl start rke2-agent.service Alternatively, you can do this, which does the same thing systemctl enable --now rke2-agent.service systemctl status rke2-agent.service 5) Check is RKE2 Agent is running systemctl status rke2-agent.service Run this command in RKE2 Server to check if RKE2 Agents are communicating with the RKE2 Server. kubectl get node -o wide Run this command in RKE2 Server to check all pods status. kubectl get pod -A ** NOTE ** Repeat "RKE2 Agent Installation", if you have multiple RKE2 agents. Get/Change FQDN 1) Get/Change Current hostname (OPTIONAL) nano /etc/hostname 2) Add FQDN here nano /etc/hosts Add following line #RANCHER_SERVER_IP_ADDRESS# rancher.xynet.local Rancher Install Using Helm (on RKE2 Server) 1) Install Helm curl -#L https://raw.githubusercontent.com/hel... | bash 2) Add Rancher to repo helm repo add rancher-latest https://releases.rancher.com/server-c... 3) Add Jetstack (cert mgr) to repo helm repo add jetstack https://charts.jetstack.io 4) Create cert-manager CRD kubectl apply -f https://github.com/jetstack/cert-mana... 5) Helm install Jetstack helm upgrade -i cert-manager jetstack/cert-manager --namespace cert-manager --create-namespace 6) Helm install Rancher helm upgrade -i rancher rancher-latest/rancher --create-namespace --namespace cattle-system --set hostname=rancher.xynet.local --set bootstrapPassword=rabi123 --set replicas=1 --set global.cattle.psp.enabled=false 7) Check if Rancher and Jetstack (CertManager) containers are running kubectl get pod -A curl -k https://rancher.xynet.local Lognhorn Install Using Helm (on RKE2 Server) 1) Add Longhorn to repo helm repo add longhorn https://charts.longhorn.io 2) Update helm repo update 3) Helm install Longhorn chart helm upgrade -i longhorn longhorn/longhorn --namespace longhorn-system --create-namespace 4) Check if Longhorn container is running kubectl get pod -A #linux #rancher #kubernetes #helm
