ETCD啟動(dòng)失敗-connect: no route to host

搭建K8S集群遇到ETCD的報(bào)錯(cuò)，報(bào)錯(cuò)信息如下，

一定要關(guān)閉防火墻、iptables和SELINUX，三個(gè)都要關(guān)閉！！

關(guān)閉CentOS7防火墻

查看防火墻狀態(tài)

firewall-cmd --state

停止firewall

systemctl stop firewalld.service

禁止firewall開(kāi)機(jī)啟動(dòng)

systemctl disable firewalld.service</pre>

關(guān)閉SELINUX

編輯SELINUX文件

vim /etc/selinux/config

將SELINUX=enforcing改為SELINUX=disabled

清除和關(guān)閉iptables

清空iptables規(guī)則

iptables -F

保存

iptables-save
