证书类型

类型名称	说明
client	客户端使用，用于服务端认证客户端，例如etcdctl,etcd proxy，fleectl docker 客户端
server	服务端使用，客户端以此验证服务端身份，例如docke 服务端，kube-apiserver
peer	双向证书，用于etcd集群成员间通信

# 双向证书文件peer

vi /opt/certs/etcd-peer-csr.json

# 服务器断电，etcd集群小于n/2

panic: invalid freelist page: 3487582951472510517, page type is branch：报错信息

查看etcd服务的时候，发现三个节点，只有一个节点A是运行的，其余两个节点BC是无法启动

**生产环境删除需谨慎，建议不这么恢复**
尝试解决方式：我把B 和 C 的data目录数据删除了，A 还是正常运行的状态，还是无法启动B 和C（ 删除(或者移走)数据你可以先尝试不删除，先把A 停止，去启动B和C，看看是否可启动） 

最后我是：把正常运行A的停止，B 和 C 的data目录数据删除，把不能正常运行的B和C，先执行启动命令，再把之前手动停止的A启动

恢复集群

在某种特殊情况下，导致A起不来，需要重新配置集群信息，和业务的部署

所以node节点

#检查node节点
kubectl get nodes

#检查主控服务
kubectl get cs

# Nginx-L4代理apiserver

【192.168.14.11，192.168.14.12】 主机部署Nginx 和keepalived (虚拟VIP：192.168.14.10)

安装Nginx，配置

nginx 安装建议版本：1.16 以上

nginx安装博客

yum install -y nginx

mkdir /etc/nginx/stream.d

在vi /etc/nginx/nginx.conf http上一层添加

include /etc/nginx/stream.d/*.conf;

添加stream 配置，监听7443端口

vi /etc/nginx/stream.d/apiserver.conf

stream {
    upstream kube-apiserver {
        server 192.168.14.21:6443     max_fails=3 fail_timeout=30s;
        server 192.168.14.22:6443     max_fails=3 fail_timeout=30s;
    }
    server {
        listen 7443;
        proxy_connect_timeout 2s;
        proxy_timeout 900s;
        proxy_pass kube-apiserver;

检查vip是否正常漂移，

  1.停止11 上的nginx,vip是否漂移到12
  2.启动11上的nginx,因为nopreempt 参数，vip不会立即漂移到11
  3.重启12上的keepalived ,vip检查是否漂移到11
