通过keepalived+nginx实现 k8s apiserver节点高可用

本文主要是介绍通过keepalived+nginx实现 k8s apiserver节点高可用，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

 一、环境准备

K8s 主机配置：
配置： 4Gib 内存/4vCPU/60G 硬盘
网络：机器相互可以通信

k8s 实验环境网络规划：
podSubnet（pod 网段） 10.244.0.0/16
serviceSubnet（service 网段）: 10.96.0.0/12
物理机网段：192.168.1.0/24

2个控制节点2个工作节点

K8S集群角色	IP地址	主机名	安装的组件
控制节点	192.168.1.63	xuegod63	apiserver、controllermanager、schedule、kubelet、etcd、kubeproxy、容器运行时、calico、keepalived、nginx、kubeadm、kubectl
控制节点	192.168.1.64	xuegod64	apiserver、controllermanager、schedule、kubelet、etcd、kubeproxy、容器运行时、calico、keepalived、nginx、kubeadm、kubectl
工作节点	192.168.1.65	xuegod65	Kube-proxy、calico、coredns、容器运行时、kubelet、kubeadm、kubectl
工作节点	192.168.1.62	xuegod62	Kube-proxy、calico、coredns、容器运行时、kubelet、kubeadm、kubectl
VIP	192.168.1.199

初始化安装安装到第三步https://candy.blog.csdn.net/article/details/134723910?spm=1001.2014.3001.5502

上面的安装到第三步，安装初始化 k8s 需要的组件，
[root@xuegod63 ~]# yum install -y kubelet-1.26.0 kubeadm-1.26.0 kubectl-1.26.0
[root@xuegod63 ~]# systemctl enable kubelet

二、63、64 安装keepalived+nginx

1、安装 nginx 和 keepalived 

在 xuegod63 和 xuegod64 上安装 keepalived 和 nginx，实现对 apiserver 负载均衡和反向代
理。Xuegod63 是 keepalived 主节点，xuegod64 是 keepalived 备节点。
[root@xuegod63 ~]# yum install epel-release nginx keepalived nginx-mod-stream -y
[root@xuegod64 ~]# yum install epel-release nginx keepalived nginx-mod-stream -y
[root@xuegod63 ~]# vim /etc/nginx/nginx.conf

2.修改配置63、64 nginx 配置文件 

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;include /usr/share/nginx/modules/*.conf;events {worker_connections 1024;
}# 四层负载均衡，为两台Master apiserver组件提供负载均衡
stream {log_format  main  '$remote_addr $upstream_addr - [$time_local] $status $upstream_bytes_sent';access_log  /var/log/nginx/k8s-access.log  main;upstream k8s-apiserver {server 192.168.1.63:6443 weight=5 max_fails=3 fail_timeout=30s;  server 192.168.1.64:6443 weight=5 max_fails=3 fail_timeout=30s;         }server {listen 16443; # 由于nginx与master节点复用，这个监听端口不能是6443，否则会冲突proxy_pass k8s-apiserver;}
}http {log_format  main  '$remote_addr - $remote_user [$time_local] "$request" ''$status $body_bytes_sent "$http_referer" ''"$http_user_agent" "$http_x_forwarded_for"';access_log  /var/log/nginx/access.log  main;sendfile            on;tcp_nopush          on;tcp_nodelay         on;keepalive_timeout   65;types_hash_max_size 2048;include             /etc/nginx/mime.types;default_type        application/octet-stream;server {listen       80 default_server;server_name  _;location / {}}
}

 备注：
nginx 配置文件参数解释：
1、weight 指定了每个后端服务器的权重，用于调节请求的分配比例，例如上述配置中三个后端服务器的权重都为 5，则每个服务器会均衡地处理 1/3 的请求。
2、max_fails 指定了最大的失败次数，如果在 fail_timeout 时间内连续失败了 max_fails 次，则该
后端服务器会被暂时认为是不可用的，不再向其分配请求。
3、fail_timeout 指定了服务器被认为是不可用的时间，即在该时间段内连续失败了 max_fails 次，则该后端服务器会被暂时认为是不可用的。

3、修改 keepalive 配置文件，主备不一样，需要区分

63是主节点的修改 [root@xuegod63 ~]# vim /etc/keepalived/keepalived.conf   

注意：63、64网卡根据自己的实际情况进行修改

global_defs { notification_email { acassen@firewall.loc failover@firewall.loc sysadmin@firewall.loc } notification_email_from Alexandre.Cassen@firewall.loc  smtp_server 127.0.0.1 smtp_connect_timeout 30 router_id NGINX_MASTER
} vrrp_script check_nginx {script "/etc/keepalived/check_nginx.sh"
}vrrp_instance VI_1 { state MASTER interface ens33  # 修改为实际网卡名virtual_router_id 51 # VRRP 路由 ID实例，每个实例是唯一的 priority 100    # 优先级，备服务器设置 90 advert_int 1    # 指定VRRP 心跳包通告间隔时间，默认1秒 authentication { auth_type PASS      auth_pass 1111 }  # 虚拟IPvirtual_ipaddress { 192.168.1.199/24} track_script {check_nginx} 
}

配置文件一样64修改 [root@xuegod64 ~]# vim /etc/keepalived/keepalived.conf   

global_defs { notification_email { acassen@firewall.loc failover@firewall.loc sysadmin@firewall.loc } notification_email_from Alexandre.Cassen@firewall.loc  smtp_server 127.0.0.1 smtp_connect_timeout 30 router_id NGINX_MASTER
} vrrp_script check_nginx {script "/etc/keepalived/check_nginx.sh"
}vrrp_instance VI_1 { state BACKUP interface ens33  # 修改为实际网卡名virtual_router_id 51 # VRRP 路由 ID实例，每个实例是唯一的 priority 90    # 优先级，备服务器设置 90 advert_int 1    # 指定VRRP 心跳包通告间隔时间，默认1秒 authentication { auth_type PASS      auth_pass 1111 }  # 虚拟IPvirtual_ipaddress { 192.168.1.199/24} track_script {check_nginx} 
}

4.检测nginx运行的脚本 

这有个检测nginx脚本 vi  /etc/keepalived/check_nginx.sh   （63、64都在执行）

chmod +x /etc/keepalived/check_nginx.sh

#!/bin/bash
#1、判断Nginx是否存活
counter=$(ps -ef |grep nginx | grep sbin | egrep -cv "grep|$$" )
if [ $counter -eq 0 ]; then#2、如果不存活则尝试启动Nginxservice nginx startsleep 2#3、等待2秒后再次获取一次Nginx状态counter=$(ps -ef |grep nginx | grep sbin | egrep -cv "grep|$$" )#4、再次进行判断，如Nginx还不存活则停止Keepalived，让地址进行漂移if [ $counter -eq 0 ]; thenservice  keepalived stopfi
fi

5、启动服务：

[root@xuegod63 ~]# systemctl daemon-reload && systemctl start nginx
[root@xuegod63 ~]# systemctl start keepalived && systemctl enable nginx keepalived
[root@xuegod64 ~]# systemctl daemon-reload && systemctl start nginx
[root@xuegod64 ~]# systemctl start keepalived && systemctl enable nginx keepalived

可以看到vip已经运行起来了

6、测试 vip 能否漂移：

停掉 xuegod63 上的 keepalived，Vip 会漂移到 xuegod64
[root@xuegod63 ~]# service keepalived stop
[root@xuegod64]# ip addr

 可以看到Vip 会漂移到 xuegod64

#启动 xuegod63 上的 nginx 和 keepalived，vip 又会漂移回来
[root@xuegod63 ~]# systemctl start nginx
[root@xuegod63 ~]# systemctl start keepalived
[root@xuegod63]# ip addr

可以看到已经回来了

三、kubeadm 初始化 k8s 集群

因为控制节点做了高可用，所以k8s集群里的配置要变

1.使用 kubeadm 初始化 k8s 集群

[root@xuegod63 ~]# kubeadm config print init-defaults > kubeadm.yaml

只在master1上执行；根据我们自己的需求修改配置，比如修改 imageRepository 的值，kube-proxy 的模式为ipvs，需要注意的是由于我们使用的 containerd 作为运行时，所以在初始化节点的时候需要指定cgroupDriver 为 systemd

vi kubeadm.yaml 完整配置如下：

apiVersion: kubeadm.k8s.io/v1beta3
bootstrapTokens:
- groups:- system:bootstrappers:kubeadm:default-node-tokentoken: abcdef.0123456789abcdefttl: 24h0m0susages:- signing- authentication
kind: InitConfiguration
#localAPIEndpoint:
#  advertiseAddress: 192.168.1.63
#  bindPort: 6443
nodeRegistration:criSocket: unix:///run/containerd/containerd.sockimagePullPolicy: IfNotPresent
# name: xuegod63taints: null
---
apiServer:timeoutForControlPlane: 4m0s
apiVersion: kubeadm.k8s.io/v1beta3
certificatesDir: /etc/kubernetes/pki
clusterName: kubernetes
controllerManager: {}
dns: {}
etcd:local:dataDir: /var/lib/etcd
imageRepository: registry.cn-hangzhou.aliyuncs.com/google_containers
kind: ClusterConfiguration
kubernetesVersion: 1.26.0
controlPlaneEndpoint: 192.168.1.199:16443
networking:dnsDomain: cluster.localserviceSubnet: 10.96.0.0/12podSubnet: 10.244.0.0/16
scheduler: {}
---
apiVersion: kubeproxy.config.k8s.io/v1alpha1
kind: KubeProxyConfiguration
mode: ipvs
---
apiVersion: kubelet.config.k8s.io/v1beta1
kind: KubeletConfiguration
cgroupDriver: systemd

#然后基于 kubeadm.yaml 初始化 k8s（集群资源上一篇有分享）
[root@xuegod63 ~]# ctr -n=k8s.io images import k8s_1.26.0.tar.gz
[root@xuegod62 ~]# ctr -n=k8s.io images import k8s_1.26.0.tar.gz
[root@xuegod64 ~]# ctr -n=k8s.io images import k8s_1.26.0.tar.gz
[root@xuegod65 ~]# ctr -n=k8s.io images import k8s_1.26.0.tar.gz

[root@xuegod63 ~]# 

kubeadm init --config=kubeadm.yaml --ignore-preflight-errors=SystemVerification

 Your Kubernetes control-plane has initialized successfully!  说明初始化成功

#配置 kubectl 的配置文件 config，相当于对 kubectl 进行授权，这样 kubectl 命令可以使用这个
证书对 k8s 集群进行管理
[root@xuegod63 ~]# mkdir -p $HOME/.kube
[root@xuegod63 ~]# sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
[root@xuegod63 ~]# sudo chown $(id -u):$(id -g) $HOME/.kube/config

[root@xuegod63 ~]# kubectl get nodes

2 、扩容 k8s 控制节点，把 xuegod64 加入到 k8s 集群

#把 xuegod63 节点的证书拷贝到 xuegod64 上
在 xuegod64 创建证书存放目录：
[root@xuegod64 ~]#

cd /root && mkdir -p /etc/kubernetes/pki/etcd &&mkdir -p ~/.kube/

#把 xuegod63 节点的证书拷贝到 xuegod64 上：

scp /etc/kubernetes/pki/ca.crt xuegod64:/etc/kubernetes/pki/
scp /etc/kubernetes/pki/ca.key xuegod64:/etc/kubernetes/pki/
scp /etc/kubernetes/pki/sa.key xuegod64:/etc/kubernetes/pki/
scp /etc/kubernetes/pki/sa.pub xuegod64:/etc/kubernetes/pki/
scp /etc/kubernetes/pki/front-proxy-ca.crt xuegod64:/etc/kubernetes/pki/
scp /etc/kubernetes/pki/front-proxy-ca.key xuegod64:/etc/kubernetes/pki/
scp /etc/kubernetes/pki/etcd/ca.crt xuegod64:/etc/kubernetes/pki/etcd/
scp /etc/kubernetes/pki/etcd/ca.key xuegod64:/etc/kubernetes/pki/etcd/

在 xuegod63 上查看加入节点的命令：
[root@xuegod63 ~]# kubeadm token create --print-join-command

64添加为控制节点 在 xuegod64  上执行：
[root@xuegod64 ~]#kubeadm join 192.168.1.199:16443 --token mdn9gg.dcl0i58oagtmhezn --discovery-token-ca-cert-hash sha256:bce6f69bf0b7983d300f98d0e71d8687b4b5dbc2936f1c872ca48af72716a5ba --control-plane --ignore-preflight-errors=SystemVerification

kubeadm join 192.168.1.199:16443 --token mdn9gg.dcl0i58oagtmhezn --discovery-token-ca-cert-hash sha256:bce6f69bf0b7983d300f98d0e71d8687b4b5dbc2936f1c872ca48af72716a5ba --control-plane --ignore-preflight-errors=SystemVerification

注：--control-plane  这个参数是一控制节点加入 最后再加上 --ignore-preflight-errors=SystemVerification

在 xuegod63 上查看集群状况：
[root@xuegod63 ~]# kubectl get nodes
NAME STATUS ROLES AGE VERSION
xuegod63 NotReady control-plane 49m v1.26.0
xuegod64 NotReady control-plane 39s v1.26.0

3、扩容 k8s 集群-65添加工作节点

在 xuegod63 上查看加入节点的命令：
[root@xuegod63 ~]# kubeadm token create --print-join-command

把 xuegod6 加入 k8s 集群：
[root@xuegod65~]#kubeadm join 192.168.1.199:16443 --token mdn9gg.dcl0i58oagtmhezn --discovery-token-ca-cert-hash sha256:bce6f69bf0b7983d300f98d0e71d8687b4b5dbc2936f1c872ca48af72716a5ba  --ignore-preflight-errors=SystemVerification

#在 xuegod63 上查看集群节点状况：
[root@xuegod63 ~]# kubectl get nodes

#可以对 xuegod66 打个标签，显示 work
[root@xuegod63 ~]#  kubectl get nodes

4、安装 kubernetes 网络组件-Calico

把安装 calico 需要的镜像 calico.tar.gz 传到 xuegod63、xuegod62、xuegod64 和 xuegod66
节点，手动解压：
[root@xuegod63 ~]# ctr -n=k8s.io images import calico.tar.gz
[root@xuegod62 ~]# ctr -n=k8s.io images import calico.tar.gz
[root@xuegod64 ~]# ctr -n=k8s.io images import calico.tar.gz
[root@xuegod65 ~]# ctr -n=k8s.io images import calico.tar.gz

修改 calico.yaml 文件：

如果机器有多个网卡，需要在 calico 配置文件里指定可以联网的网卡，假如机器只有一个网卡，也
要指定下，这样就直接找到可以用的网卡了。

[root@xuegod63 ~]# kubectl apply -f calico.yaml

[root@xuegod63 ~]# kubectl get nodes

5、测试 k8s 集群的 DNS 解析和网络是否正常

#把 busybox-1-28.tar.gz 上传到 xuegod66 节点，手动解压
[root@xuegod66 ~]# ctr -n=k8s.io images import busybox-1-28.tar.gz
[root@xuegod63 ~]# kubectl run busybox --image docker.io/library/busybox:1.28 --
image-pull-policy=IfNotPresent --restart=Never --rm -it busybox -- sh

/ # ping www.baidu.com
PING www.baidu.com (39.156.66.18): 56 data bytes
64 bytes from 39.156.66.18: seq=0 ttl=127 time=39.3 ms
#通过上面可以看到能访问网络，说明 calico 网络插件已经被正常安装了

 6.etcd 配置成高可用状态

修改 xuegod63、xuegod64 上的 etcd.yaml 文件
vim /etc/kubernetes/manifests/etcd.yaml 

把- --initial-cluster=xuegod63=https://192.168.1.63:2380
变成如下：
- -nitialcluster=xuegod63=https://192.168.1.63:2380,xuegod62=https://192.168.1.62:2380,xuegod
64=https://192.168.1.64:2380 

修改成功之后重启 kubelet：
[root@xuegod63 ~]# systemctl restart kubelet
[root@xuegod62 ~]# systemctl restart kubelet
[root@xuegod64 ~]# systemctl restart kubele

测试 etcd 集群是否配置成功：
[root@xuegod63 ~]# docker run --rm -it --net host -v /etc/kubernetes:/etc/kubernetes 
registry.cn-hangzhou.aliyuncs.com/google_containers/etcd:3.5.4-0 etcdctl --cert 
/etc/kubernetes/pki/etcd/peer.crt --key /etc/kubernetes/pki/etcd/peer.key --cacert 
/etc/kubernetes/pki/etcd/ca.crt member list

[root@xuegod63 ~]# docker run --rm -it --net host -v /etc/kubernetes:/etc/kubernetes 
registry.cn-hangzhou.aliyuncs.com/google_containers/etcd:3.5.4-0 etcdctl --cert 
/etc/kubernetes/pki/etcd/peer.crt --key /etc/kubernetes/pki/etcd/peer.key --cacert 
/etc/kubernetes/pki/etcd/ca.crt --
endpoints=https://192.168.1.63:2379,https://192.168.1.62:2379,https://192.168.1.64:2379 
endpoint health --cluster

显示如下，说明 etcd 集群配置成功：

[root@xuegod63 ~]# docker run --rm -it --net host -v /etc/kubernetes:/etc/kubernetes 
registry.cn-hangzhou.aliyuncs.com/google_containers/etcd:3.5.4-0 etcdctl -w table --cert 
/etc/kubernetes/pki/etcd/peer.crt --key /etc/kubernetes/pki/etcd/peer.key --cacert 
/etc/kubernetes/pki/etcd/ca.crt --
endpoints=https://192.168.1.63:2379,https://192.168.1.62:2379,https://192.168.1.64:2379 
endpoint status --cluster
