This article is about Kubernetes multi-node deployment. The editor thought it was very practical, so I shared it with you to learn. The following information is about Kubernetes multi-node deployment.

1. Remote replication of master related directories

Turn off firewall and security functions systemctl stop firewalld.servicesetenforce 0 copy kubernetes directory to master2scp-r / opt/kubernetes/ root@192.168.142.120:/opt copy etcd directory to master2 (including certificates) scp-r / opt/etcd/ root@192.168.142.120:/opt replication service startup script to master2scp / usr/lib/systemd/system/ {kube-apiserver,kube-controller-manager,kube-scheduler} .service root@192.168.142.120:/usr/lib/systemd/system/

two。 Modify kube-apiserver configuration file

Vim / opt/kubernetes/cfg/kube-apiserver# changes lines 5 and 7 IP address to the address of the master2 host-- bind-address=192.168.142.120\-- advertise-address=192.168.142.120\

3. Start the service and set to boot automatically

Systemctl start kube-apiserver.servicesystemctl enable kube-apiserver.servicesystemctl start kube-controller-manager.servicesystemctl enable kube-controller-manager.servicesystemctl start kube-scheduler.servicesystemctl enable kube-scheduler.service

4. Append environment variables and take effect

Add export PATH=$PATH:/opt/kubernetes/bin/source / etc/profile at the end of vim / etc/profile#

5. View the node node

Kubectl get nodeNAME STATUS ROLES AGE VERSION192.168.142.130 Ready 10d12h v1.12.3192.168.142.131 Ready 10d11h v1.12.3 II, Nginx load balance deployment-keeplived service

1. Operation on the lbm& LBB side to install the nginx service

Copy the nginx.sh and keepalived.conf scripts to the home directory (used later) # nginx.shcat > / etc/yum.repos.d/nginx.repo dashboard-csr.json
