生成token

cd /server/ssl
token=`head -c 16 /dev/urandom | od -An -t x | tr -d ' '`
echo "$token,kubelet-bootstrap,10001,'system:kubelet-bootstrap'" >token.csv

把master的组件, 证书和私钥以及apiserver的启动文件发送master01上

cd /server/ssl 
scp token.csv kubernetes*.pem master01:/opt/kubernetes/ssl/
scp kube-apiserver.service master01:/usr/lib/systemd/system/
cd /tools/kubernetes/server/bin
scp kube-apiserver kube-controller-manager kube-scheduler kubectl master01:/opt/kubernetes/bin/

启动apiserver

systemctl daemon-reload
systemctl start kube-apiserver
systemctl enable kube-apiserver
systemctl status kube-apiserver
