下文给大家带来kubernetes二进制负载均衡部署如何实现，希望能够给大家在实际运用中带来一定的帮助，负载均衡涉及的东西比较多，理论也不多，网上有很多书籍，今天我们就用天达云在行业内累计的经验来做一个解答。
实验环境：
负载均衡
Nginx1:192.168.35.104/24
Nginx2:192.168.35.105/24
Master节点
master1:192.168.35.100/24
master2:192.168.35.103/24
Node节点
node1：192.168.35.101/24
node2：192.168.35.102/24
nginx安装部署
lb01和lb02操作
1、关闭防火墙
[root@localhost ~]# systemctl stop firewalld.service
[root@localhost ~]# setenforce 0
2、安装nginx服务，把nginx.sh和keepalived.conf脚本拷贝到家目录
[root@localhost ~]# ls
anaconda-ks.cfg keepalived.conf 公共 视频 文档 音乐
initial-setup-ks.cfg nginx.sh 模板 图片 下载 桌面
3、构建nginx的yum源环境
（1）复制配置文件
[root@localhost ~]# vim nginx.sh
cat > /etc/yum.repos.d/nginx.repo << EOF
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0 #复制四行内容
EOF
stream {
log_format main '$remote_addr $upstream_addr - [$time_local] $status $upstream_bytes_sent';
access_log /var/log/nginx/k8s-access.log main;
upstream k8s-apiserver {
server 10.0.0.3:6443;
server 10.0.0.8:6443;
}
server {
listen 6443;
proxy_pass k8s-apiserver;
}
}
（2）创建yum源，重新加载yum仓库，并安装nginx
[root@localhost ~]# vim /etc/yum.repos.d/nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
[root@localhost ~]# yum list
[root@localhost ~]# yum install nginx -y
4、添加四层转发
（1）复制配置文件
[root@localhost ~]# vim nginx.sh
cat > /etc/yum.repos.d/nginx.repo << EOF
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
EOF
stream {
log_format main '$remote_addr $upstream_addr - [$time_local] $status $upstream_bytes_sent';
access_log /var/log/nginx/k8s-access.log main;
upstream k8s-apiserver {
server 10.0.0.3:6443;
server 10.0.0.8:6443;
}
server {
listen 6443;
proxy_pass k8s-apiserver;
}
} #复制此段内容
（2）添加配置文件并修改
[root@localhost ~]# vim /etc/nginx/nginx.conf
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
stream {
log_format main '$remote_addr $upstream_addr - [$time_local] $status $upstream_bytes_sent';
access_log /var/log/nginx/k8s-access.log main;
upstream k8s-apiserver {
server 192.168.35.100:6443;
server 192.168.35.103:6443; #只需修改IP为master1和master2的地址
}
server {
listen 6443;
proxy_pass k8s-apiserver;
}
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$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;
keepalive_timeout 65;
#gzip on;
include /etc/nginx/conf.d/*.conf;
}
（3）验证语法是否错误
[root@localhost ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
（4）修改首页，进行区分，一个master，一个backup。
lb01操作：
[root@localhost ~]# cd /usr/share/nginx/html/
[root@localhost html]# ls
50x.html index.html
[root@localhost html]# vim index.html
/14 <h3>Welcome to master ginx!</h3>
lb02操作：
[root@localhost ~]# cd /usr/share/nginx/html/
[root@localhost html]# ls
50x.html index.html
[root@localhost html]# vim index.html
/14 <h3>Welcome to backup ginx!</h3>
（5）开启服务，并访问首页
lb01：
[root@localhost ~]# systemctl start nginx
用浏览器访问http://192.168.35.104/
lb02：
[root@localhost ~]# systemctl start nginx
用浏览器访问http://192.168.35.105/
keepalived安装部署
lb01和lb02操作：
1、安装keepalived
[root@localhost ~]# yum install keepalived -y
2、修改配置文件
[root@localhost ~]# ls
anaconda-ks.cfg keepalived.conf 公共 视频 文档 音乐
initial-setup-ks.cfg nginx.sh 模板 图片 下载 桌面
[root@localhost ~]# cp keepalived.conf /etc/keepalived/keepalived.conf
cp：是否覆盖"/etc/keepalived/keepalived.conf"？ yes
[root@localhost ~]# vim /etc/keepalived/keepalived.conf
lb01是Master配置如下：
! Configuration File for keepalived
global_defs {
# 接收邮件地址
notification_email {
acassen@firewall.loc
failover@firewall.loc
sysadmin@firewall.loc
}
# 邮件发送地址
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
}
virtual_ipaddress {
192.168.35.200/24
}
track_script {
check_nginx
}
}
lb02是Backup配置如下：
! Configuration File for keepalived
global_defs {
# 接收邮件地址
notification_email {
acassen@firewall.loc
failover@firewall.loc
sysadmin@firewall.loc
}
# 邮件发送地址
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 BACKUP
interface ens33
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
}
virtual_ipaddress {
192.168.35.200/24
}
track_script {
check_nginx
}
}
3、制作管理脚本
[root@localhost ~]# vim /etc/nginx/check_nginx.sh
count=$(ps -ef |grep nginx |egrep -cv "grep|$$")
if [ "$count" -eq 0 ];then
systemctl stop keepalived
fi
4、赋予执行权限并开启服务
[root@localhost ~]# chmod +x /etc/nginx/check_nginx.sh
[root@localhost ~]# systemctl start keepalived
5、查看地址信息
（1）查看lb01地址信息
[root@localhost ~]# 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

4: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast master virbr0 state DOWN qlen 1000
link/ether 52:54:00:14:39:99 brd ff:ff:ff:ff:ff:ff
6、测试故障转移切换
（1）验证地址漂移（lb01中使用pkill nginx，再在lb02中使用ip a 查看）
[root@localhost ~]# pkill nginx
[root@localhost ~]# systemctl status nginx

（3）nginx站点/usr/share/nginx/html
在宿主机上ping虚拟IP，保证可以ping通，说明可以去进行访问
在lb01查看index.html
[root@localhost ~]# cat /usr/share/nginx/html/index.html
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
body {

因为漂移地址是在lb01上，所以访问漂移地址时现实的nginx首页应该是包含master的
node节点绑定VIP地址
1、修改node节点配置文件统一VIP（bootstrap.kubeconfig,kubelet.kubeconfig）
[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
#全部都改为VIP地址
server: https://192.168.35.200:6443
2、替换完成直接自检
[root@localhost ~]# cd /opt/kubernetes/cfg/
[root@localhost cfg]# grep 200 *
bootstrap.kubeconfig: server: https://192.168.35.200:6443
kubelet.kubeconfig: server: https://192.168.35.200:6443
kube-proxy.kubeconfig: server: https://192.168.35.200:6443
3、重启服务
[root@localhost cfg]# systemctl restart kubelet.service
[root@localhost cfg]# systemctl restart kube-proxy.service
4、在lb01上查看nginx的k8s日志
[root@localhost ~]# tail /var/log/nginx/k8s-access.log
192.168.35.102 192.168.35.100:6443 - [08/Feb/2020:17:42:00 +0800] 200 1119
192.168.35.102 192.168.35.103:6443 - [08/Feb/2020:17:42:00 +0800] 200 1121
192.168.35.101 192.168.35.100:6443 - [08/Feb/2020:17:42:14 +0800] 200 1121
192.168.35.101 192.168.35.100:6443 - [08/Feb/2020:17:42:14 +0800] 200 1121
在master01上操作
1、测试创建pod
[root@localhost k8s]# 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
2、查看状态
[root@localhost k8s]# kubectl get pods
NAME READY STATUS RESTARTS AGE
nginx-dbddb74b8-cfggf 1/1 0 ContainerCreating 64s #正在创建中
[root@localhost k8s]# kubectl get pods
NAME READY STATUS RESTARTS AGE
nginx-dbddb74b8-cfggf 1/1 Running 0 74s #创建完成，运行中
3、注意日志问题（无法查看，会报错）
[root@localhost k8s]# kubectl logs nginx-dbddb74b8-cfggf
Error from server (Forbidden): Forbidden (user=system:anonymous, verb=get, resource=nodes, subresource=proxy) ( pods/log nginx-dbddb74b8-cfggf)
解决办法：
（1）权限提升
[root@localhost k8s]# kubectl create clusterrolebinding cluster-system-anonymous --clusterrole=cluster-admin --user=system:anonymous
clusterrolebinding.rbac.authorization.k8s.io/cluster-system-anonymous created
（2）在去进行日志查看
[root@localhost k8s]# kubectl logs nginx-dbddb74b8-cfggf
//并不会出现报错，只是因为没有去访问，所以没有产生日志
4、查看pod网络
[root@localhost k8s]# kubectl get pods -o wide
NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE
nginx-dbddb74b8-cfggf 1/1 Running 0 14m 172.17.45.2 192.168.35.101 <none>
5、在对应网段的node节点上操作可以直接访问
[root@localhost cfg]# curl 172.17.45.2
<!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>
<h3>Welcome to nginx!</h3>
<p>If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.</p>

<p><em>Thank you for using nginx.</em></p>
</body>
</html>
6、访问就会产生日志，回到master01操作
[root@localhost k8s]# kubectl logs nginx-dbddb74b8-cfggf172.17.45.1 - - [08/Feb/2020:10:10:29 +0000] "GET / HTTP/1.1" 200 612 "-" "curl/7.29.0" "-"
