Centos7重启后k8s无法正常启动

重启了centos后，发现k8s没有正常启动

# kubectl get nodes

提示无法正常连接，查看k8s是否正常启动

# systemctl status kubelet

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

查看相关日志

# journalctl -xefu kubelet

发现时swap没有关闭导致的

# 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
