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,三台都安装
[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 ~]#
vi /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IP virtual_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IP virtual_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|$$" ) if [ $counter -eq 0 ]; then #2、如果不存活则尝试启动Nginx service nginx start sleep 2 #3、等待2秒后再次获取一次Nginx状态 counter=$(ps -ef |grep nginx | grep sbin | egrep -cv "grep|$$" ) #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 ]; then service keepalived stop fi 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-token token: abcdef.0123456789abcdef ttl: 24h0m0s usages: - signing - authentication kind: InitConfiguration #localAPIEndpoint: # advertiseAddress: 192.168.1.63 # bindPort: 6443 nodeRegistration: criSocket: unix:///run/containerd/containerd.sock imagePullPolicy: IfNotPresent # name: xuegod63 taints: 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.local serviceSubnet: 10.96.0.0/12 podSubnet: 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)上传资源
[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 这个不要复制,每次生成的不一样
后面加上 --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
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
给xuegod打上work工作标签节点
kubectl label nodes xuegod65 node-role.kubernetes.io/work=work
再次查看
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,在3644行后面指定你网卡
- name: IP_AUTODETECTION_METHOD
value: "interface=ens33"
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(也可以指定,上面的没子指定)。
[root@xuegod63 ~]# kubectl apply -f calico.yaml (只在一台机器上安装就可以)
[root@xuegod63 ~]# kubectl get nodes
查看
查看各节点状态kubectl get pods -n kube-system
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 xuegod65 工作节点 pod在工作节点运行,手动解压
[root@xuegod65 ~]# 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
