Kubernetes-----多节点部署+负载均衡_批量节点云部署和负载均衡-优快云博客

本文档详细介绍了如何在Kubernetes环境中进行多节点部署，包括master02的设置步骤和Nginx01/Nginx02的配置，以实现负载均衡。内容涉及复制组件、修改配置、证书同步、服务启动、环境变量设定、Nginx与Keepalived的安装及配置，以及VIP地址漂移的验证。最后提到了在集群中创建pod的测试过程。

实验环境

主机名	操作系统	IP地址
master01	centos7	20.0.0.14
nginx01	centos7	20.0.0.15
nginx02	centos7	20.0.0.16

本次实验基于单节点部署完之后~~~~~~~~

一、master02部署

1、在master01上复制kubernetes目录到master02

[root@master01 ~]# scp -r /opt/kubernetes/ root@20.0.0.14:/opt/
token.csv                                                                100%   84   162.5KB/s   00:00    
kube-apiserver                                                           100%  909     1.7MB/s   00:00    
kube-scheduler                                                           100%   94   125.4KB/s   00:00    
kube-controller-manager                                                  100%  483   951.7KB/s   00:00    
kubectl                                                                  100%   55MB 103.2MB/s   00:00    
kube-controller-manager                                                  100%  155MB  96.3MB/s   00:01    
kube-scheduler                                                           100%   55MB  80.9MB/s   00:00    
kube-apiserver                                                           100%  184MB  70.0MB/s   00:02    
ca-key.pem                                                               100% 1679     2.4MB/s   00:00    
ca.pem                                                                   100% 1359     1.1MB/s   00:00    
server-key.pem                                                           100% 1675     2.0MB/s   00:00    
server.pem                                                               100% 1643     2.0MB/s   00:00

master02验证

[root@master02 ~]# ls /opt/kubernetes/
bin  cfg  ssl

2、复制master01中的三个组件启动脚本

[root@master01 ~]# scp /usr/lib/systemd/system/{
   
   kube-apiserver,kube-controller-manager,kube-scheduler}.service root@20.0.0.14:/usr/lib/systemd/system
root@20.0.0.14's password: 
kube-apiserver.service                                                   100%  282   535.0KB/s   00:00    
kube-controller-manager.service                                          100%  317   589.7KB/s   00:00    
kube-scheduler.service                                                   100%  281   385.1KB/s   00:00

3、修改master02配置文件kube-apiserver中的IP

[root@master02 ~]# cd /opt/kubernetes/cfg/
[root@master02 cfg]# ls
kube-apiserver  kube-controller-manager  kube-scheduler  token.csv
[root@master02 cfg]# vi kube-apiserver 
KUBE_APISERVER_OPTS="--logtostderr=true \
--v=4 \
--etcd-servers=https://20.0.0.11:2379,https://20.0.0.12:2379,https://20.0.0.13:2379 \
--bind-address=20.0.0.14 \                      # 修改成master02 IP地址
--secure-port=6443 \
--advertise-address=20.0.0.14 \                # 修改成master02 IP地址
--allow-privileged=true \
--service-cluster-ip-range=10.0.0.0/24 \
--enable-admission-plugins=NamespaceLifecycle,LimitRanger,ServiceAccount,ResourceQuota,NodeRestriction \
--authorization-mode=RBAC,Node \
--kubelet-https=true \
--enable-bootstrap-token-auth \
--token-auth-file=/opt/kubernetes/cfg/token.csv \
--service-node-port-range=30000-50000 \
--tls-cert-file=/opt/kubernetes/ssl/server.pem  \
--tls-private-key-file=/opt/kubernetes/ssl/server-key.pem \
--client-ca-file=/opt/kubernetes/ssl/ca.pem \
--service-account-key-file=/opt/kubernetes/ssl/ca-key.pem \
--etcd-cafile=/opt/etcd/ssl/ca.pem \
--etcd-certfile=/opt/etcd/ssl/server.pem \
--etcd-keyfile=/opt/etcd/ssl/server-key.pem"
