K8S服务器意外重启，haproxy 的服务丢失的解决办法

haproxy 服务启动不起来，原因是服务器重启后导致目录丢失。k8s产生了异常。

lb 的原理需要指定一个VIP

for i in {1..65536}; do if echo &>/dev/null > /dev/tcp/127.0.0.1/${i} ;then echo -e "t33[31;40m${i}33[0m is open"; fi; done

/usr/sbin/haproxy -f /etc/haproxy/haproxy.cfg -p /run/haproxy

cd /run

mkdir haproxy

K8S vip 的两个服务

systemctl restart haproxy.service
systemctl restart keepalived.service

systemctl status haproxy.service
systemctl status keepalived.service
