多master群集架構(gòu)圖：

master2部署

1、優(yōu)先關(guān)閉master2的防火墻服務(wù)

[root@master2 ~]# systemctl stop firewalld.service
[root@master2 ~]# setenforce 0

2、在master1上操作，復(fù)制kubernetes目錄、server組件到master2

[root@master1 k8s]# scp -r /opt/kubernetes/ root@192.168.18.140:/opt
[root@master1 k8s]# scp /usr/lib/systemd/system/{kube-apiserver,kube-controller-manager,kube-scheduler}.service root@192.168.18.140:/usr/lib/systemd/system/

3、修改master02中的配置文件

[root@master2 ~]# cd /opt/kubernetes/cfg/
[root@master2 cfg]# vim kube-apiserver
5 --bind-address=192.168.18.140 \\\\
7 --advertise-address=192.168.18.140 \\\\
#第5和7行IP地址需要改為master2的地址

4、拷貝master1上已有的etcd證書給master2使用

（注意：master2一定要有etcd證書，否則apiserver服務(wù)無(wú)法啟動(dòng)）

[root@master1 k8s]# scp -r /opt/etcd/ root@192.168.18.132:/opt/
root@192.168.18.132\\\'s 
etcd                                                      100%  516   535.5KB/s   00:00
etcd                                                      100%   18MB  90.6MB/s   00:00
etcdctl                                                   100%   15MB  80.5MB/s   00:00
ca-key.pem                                                100% 1675     1.4MB/s   00:00
ca.pem                                                    100% 1265   411.6KB/s   00:00
server-key.pem                                            100% 1679     2.0MB/s   00:00
server.pem                                                100% 1338   429.6KB/s   00:00

5、啟動(dòng)master2中的三個(gè)組件服務(wù)

[root@master2 cfg]# systemctl start kube-apiserver.service        ##開啟服務(wù)
[root@master2 cfg]# systemctl enable kube-apiserver.service    ##服務(wù)開機(jī)自啟
[root@master2 cfg]# systemctl start kube-controller-manager.service
[root@master2 cfg]# systemctl enable kube-controller-manager.service
[root@master2 cfg]# systemctl start kube-scheduler.service
[root@master2 cfg]# systemctl enable kube-scheduler.service

6、修改環(huán)境變量

[root@master2 cfg]# vim /etc/profile
export PATH=$PATH:/opt/kubernetes/bin/  ##添加環(huán)境變量
[root@master2 cfg]# source /etc/profile      ##刷新配置文件
[root@master2 cfg]# kubectl get node        ##查看群集節(jié)點(diǎn)信息
NAME             STATUS   ROLES    AGE   VERSION
192.168.18.129   Ready    <none>   21h   v1.12.3
192.168.18.130   Ready    <none>   22h   v1.12.3
#此時(shí)可以看到node1和node2的加入情況

——此時(shí)master2部署完畢——
Nginx負(fù)載均衡部署
lb01和lb02進(jìn)行相同操作

安裝nginx服務(wù)，把nginx.sh和keepalived.conf腳本拷貝到家目錄

[root@localhost ~]# ls
anaconda-ks.cfg ? ? ? keepalived.conf ?公共 ?視頻 ?文檔 ?音樂(lè)
initial-setup-ks.cfg ?nginx.sh ? ? ? ? 模板 ?圖片 ?下載 ?桌面

[root@lb1 ~]# systemctl stop firewalld.service
[root@lb1 ~]# setenforce 0
[root@lb1 ~]# vim /etc/yum.repos.d/nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
##重新加載yum倉(cāng)庫(kù)
[root@lb1 ~]# yum list
##安裝nginx服務(wù)
[root@lb1 ~]# yum install nginx -y

[root@lb1 ~]# vim /etc/nginx/nginx.conf
##在12行下插入stream模塊
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 192.168.18.128:6443;     #此處為master1的ip地址
        server 192.168.18.140:6443;     #此處為master2的ip地址
    }
    server {
                listen 6443;
                proxy_pass k8s-apiserver;
    }
    }

##檢測(cè)語(yǔ)法
[root@lb1 ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
##修改主頁(yè)進(jìn)行區(qū)分
[root@lb1 ~]# cd /usr/share/nginx/html/
[root@lb1 html]# ls
50x.html  index.html
[root@lb1 html]# vim index.html
14 <h2>Welcome to mater nginx!</h2>     #14行中添加master以作區(qū)分
[root@lb2 ~]# cd /usr/share/nginx/html/
[root@lb2 html]# ls
50x.html  index.html
[root@lb1 html]# vim index.html
14 <h2>Welcome to backup nginx!</h2>        #14行中添加backup以作區(qū)分

##啟動(dòng)服務(wù)
[root@lb1 ~]# systemctl start nginx
[root@lb2 ~]# systemctl start nginx

瀏覽器驗(yàn)證訪問(wèn)，輸入192.168.18.150，可以訪問(wèn)master的nginx主頁(yè)

瀏覽器驗(yàn)證訪問(wèn)，輸入192.168.18.151，可以訪問(wèn)backup的nginx主頁(yè)

keepalived安裝部署

lb01和lb02操作相同

1、安裝keeplived

[root@lb1 html]# yum install keepalived -y

2、修改配置文件

[root@lb1~]# ls
anaconda-ks.cfg ? ? ? keepalived.conf ?公共 ?視頻 ?文檔 ?音樂(lè)
initial-setup-ks.cfg ?nginx.sh ? ? ? ? 模板 ?圖片 ?下載 ?桌面
[root@lb1 ~]# cp keepalived.conf /etc/keepalived/keepalived.conf
cp：是否覆蓋/etc/keepalived/keepalived.conf？ yes

[root@lb1 ~]# vim /etc/keepalived/keepalived.conf?
#lb01是Master配置如下：
! Configuration File for keepalived

global_defs {
? ?# 接收郵件地址
? ?notification_email {
? ? ?acassen@firewall.loc
? ? ?failover@firewall.loc
? ? ?sysadmin@firewall.loc
? ?}
? ?# 郵件發(fā)送地址
? ?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/nginx/check_nginx.sh
}

vrrp_instance VI_1 {
? ? state MASTER?
? ? interface ens33
? ? virtual_router_id 51 # VRRP 路由 ID實(shí)例，每個(gè)實(shí)例是唯一的
? ? priority 100 ? ?# 優(yōu)先級(jí)，備服務(wù)器設(shè)置 90 ?
? ? advert_int 1 ? ?# 指定VRRP 心跳包通告間隔時(shí)間，默認(rèn)1秒
? ? authentication { ?
? ? ? ? auth_type PASS
? ? ? ? auth_pass 1111
? ? } 
? ? virtual_ipaddress {
? ? ? ? 192.168.18.100/24
? ? }
? ? track_script {
? ? ? ? check_nginx
? ? }
}

#lb02是Backup配置如下：! Configuration File for keepalived

global_defs {
? ?# 接收郵件地址
? ?notification_email {
? ? ?acassen@firewall.loc
? ? ?failover@firewall.loc
? ? ?sysadmin@firewall.loc
? ?}
? ?# 郵件發(fā)送地址
? ?notification_email_from Alexandre.Cassen@firewall.loc

}

vrrp_instance VI_1 {
? ? state?BACKUP?
? ? interface ens33
? ? virtual_router_id 51 # VRRP 路由 ID實(shí)例，每個(gè)實(shí)例是唯一的
? ? priority 90 ? ?# 優(yōu)先級(jí)，備服務(wù)器設(shè)置 90 ?

? ? authentication { ?
? ? ? ? auth_type PASS
? ? ? ? auth_pass 1111
? ? } 
? ? virtual_ipaddress {
? ? ? ? 192.168.18.100/24
? ? }
? ? track_script {
? ? ? ? check_nginx
? ? }
}

3、制作管理腳本

[root@lb1 ~]# vim /etc/nginx/check_nginx.sh

count=$(ps -ef |grep nginx |egrep -cv grep|$$)

if [ $count -eq 0 ];then
? ? ? ? systemctl stop keepalived
fi

4、賦予執(zhí)行權(quán)限并開啟服務(wù)

[root@lb1 ~]# chmod  x /etc/nginx/check_nginx.sh
[root@lb1 ~]# systemctl start keepalived

5、查看地址信息
lb01地址信息

[root@lb1 ~]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1
? ? link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

因?yàn)槠频刂肥窃趌b01上，所以訪問(wèn)漂移地址時(shí)現(xiàn)實(shí)的nginx首頁(yè)應(yīng)該是包含master的

node節(jié)點(diǎn)綁定VIP地址

1、修改node節(jié)點(diǎn)配置文件統(tǒng)一VIP

[root@localhost ~]# vim /opt/kubernetes/cfg/bootstrap.kubeconfig
[root@localhost ~]# vim /opt/kubernetes/cfg/kubelet.kubeconfig
[root@localhost ~]# vim /opt/kubernetes/cfg/kube-proxy.kubeconfig

#全部都改為VIP地址

server: https://192.168.18.100:6443

2、替換完成直接自檢并重啟服務(wù)

[root@node1 ~]# cd /opt/kubernetes/cfg/
[root@node1 cfg]# grep 100 *
bootstrap.kubeconfig:    server: https://192.168.18.100:6443
kubelet.kubeconfig:    server: https://192.168.18.100:6443
kube-proxy.kubeconfig:    server: https://192.168.18.100:6443

[root@node1 cfg]# systemctl restart kubelet.service
[root@node1 cfg]# systemctl restart kube-proxy.service

3、在lb01上查看nginx的k8s日志

[root@lb1 ~]# tail /var/log/nginx/k8s-access.log

4、在master1上操作

#測(cè)試創(chuàng)建pod
[root@master1 ~]# kubectl run nginx --image=nginx
kubectl run --generator=deployment/apps.v1beta1 is DEPRECATED and will be removed in a future version. Use kubectl create instead.
deployment.apps/nginx created

#查看狀態(tài)
[root@master1 ~]# kubectl get pods
NAME                    READY   STATUS              RESTARTS   AGE
nginx-dbddb74b8-7hdfj   0/1     ContainerCreating   0          32s
#此時(shí)狀態(tài)為ContainerCreating正在創(chuàng)建中

[root@master1 ~]# kubectl get pods
NAME                    READY   STATUS    RESTARTS   AGE
nginx-dbddb74b8-7hdfj   1/1     Running   0          73s
#此時(shí)狀態(tài)為Running，表示創(chuàng)建完成，運(yùn)行中

#注意：日志問(wèn)題
[root@master1 ~]# kubectl logs nginx-dbddb74b8-7hdfj
Error from server (Forbidden): Forbidden (user=system:anonymous, verb=get, resource=nodes, subresource=proxy) ( pods/log nginx-dbddb74b8-7hdfj)
#此時(shí)日志不可看，需要開啟權(quán)限

#綁定群集中的匿名用戶賦予管理員權(quán)限
[root@master1 ~]# kubectl create clusterrolebinding cluster-system-anonymous --clusterrole=cluster-admin --user=system:anonymous
clusterrolebinding.rbac.authorization.k8s.io/cluster-system-anonymous created
[root@master1 ~]# kubectl logs nginx-dbddb74b8-7hdfj        #此時(shí)就不會(huì)報(bào)錯(cuò)了

查看pod網(wǎng)絡(luò)#
[root@master1 ~]# kubectl get pods -o wide
NAME                  READY     STATUS    RESTARTS   AGE      IP            NODE         NOMINATED NODE
nginx-dbddb74b8-7hdfj   1/1     Running   0          20m   172.17.32.2   192.168.18.129  <none>

5、在對(duì)應(yīng)網(wǎng)段的node1節(jié)點(diǎn)上操作可以直接訪問(wèn)

[root@node1 ~]# curl 172.17.32.2
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
    body {
        width: 35em;
        margin: 0 auto;
        font-family: Tahoma, Verdana, Arial, sans-serif;
    }
</style>
</head>
<body>
<h2>Welcome to nginx!</h2>

#此時(shí)看到的就是容器中nginx的信息

訪問(wèn)就會(huì)產(chǎn)生日志，我們就可以回到master1上查看日志

[root@master1 ~]# kubectl logs nginx-dbddb74b8-7hdfj
172.17.32.1 - - [07/Feb/2020:06:52:53  0000] GET / HTTP/1.1 200 612 - curl/7.29.0 -
#此時(shí)就可以看到node1使用網(wǎng)關(guān)（172.17.32.1）進(jìn)行訪問(wèn)的記錄
