All operations before the delimiter are performed on master01

Copy directory to master02

Copy the kubernetes directory to master02

[root@master K8s] # scp-r / opt/kubernetes/ root@192.168.142.120:/opt

Copy the etcd directory to master02

Master02 must have an etcd certificate, otherwise the apiserver service cannot be started

[root@master K8s] # scp-r / opt/etcd/ root@192.168.142.120:/opt replication service startup script

Kube-apiserver.service kube-controller-manager.service kube-scheduler.service

[root@master K8s] # scp / usr/lib/systemd/system/ {kube-apiserver,kube-controller-manager,kube-scheduler} .service root@192.168.142.120:/usr/lib/systemd/system/ modify service script

In fact, you only need to modify the apiserver.

[root@master02 K8s] # cd / opt/kubernetes/cfg/ [root@master02 cfg] # vim kube-apiserverKUBE_APISERVER_OPTS= "--logtostderr=true\-- etcd-servers= https://192.168.142.220:2379,https://192.168.142.136:2379, Https://192.168.142.132:2379\ # Note address change-- bind-address=192.168.142.120\-- secure-port=6443\ # Note address change-- advertise-address=192.168.142.120\-- allow-privileged=true\-- service-cluster-ip-range=10.0.0.0/24\-- enable-admission-plugins=NamespaceLifecycle,LimitRanger,ServiceAccount,ResourceQuota,NodeRestriction\-- authorization-mode=RBAC Node\-kubelet-https=true\-- enable-bootstrap-token-auth\-- token-auth-file=/opt/kubernetes/cfg/token.csv\-- service-node-port-range=30000-50000\-- tls-cert-file=/opt/kubernetes/ssl/server.pem\-- tls-private-key-file=/opt/kubernetes/ssl/server-key.pem\-- client-ca-file=/opt/kubernetes/ssl/ca.pem\-- service-account-key-file=/opt/kubernetes / ssl/ca-key.pem\-- etcd-cafile=/opt/etcd/ssl/ca.pem\-- etcd-certfile=/opt/etcd/ssl/server.pem\-- etcd-keyfile=/opt/etcd/ssl/server-key.pem "start the service [root@master02 cfg] # systemctl start kube-apiserver.service [root@master02 cfg] # systemctl start kube-controller-manager.service [root@master02 cfg] # systemctl start kube-scheduler.service result verification / / add environment variable [ Root@master02 cfg] # vim / etc/profile// add export PATH=$PATH:/opt/kubernetes/bin/ [root@master02 cfg] # source / etc/profile// at the end of [root@master02 cfg] # kubectl get nodeNAME STATUS ROLES AGE VERSION192.168.142.132 Ready 2d12h v1.12.3192.168.142.136 Ready 38h v1.12.3
