Centos7重啟后k8s無法正常啟動

重啟了centos后，發現k8s沒有正常啟動

# kubectl get nodes

提示無法正常連接，查看k8s是否正常啟動

# systemctl status kubelet

提示：Active: activating (auto-restart) (Result: exit-code)

查看相關日志

# journalctl -xefu kubelet

發現時swap沒有關閉導致的

# swapoff -a
# cp -p /etc/fstab /etc/fstab.bak$(date '+%Y%m%d%H%M%S')
# sed -i "s/\/dev\/mapper\/centos-swap/\#\/dev\/mapper\/centos-swap/g" /etc/fstab
# systemctl daemon-reload
# systemctl restart kubelet
