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.
