1.0 集群基本信息

master 192.168.211.130
node01 192.168.211.131
node02 192.168.211.132

[root@master yaml]# kubectl   get  node
NAME     STATUS   ROLES                  AGE     VERSION
master   Ready    control-plane,master   4d22h   v1.23.8
node01   Ready    worker                 4d22h   v1.23.8
node02   Ready    worker                 4d22h   v1.23.8

1. 1 准备好配置文件

安装ingress的yaml文件[此文件已经修改好了，无需修改其他的地方,直接使用]
此文件这里命名为: ingress-controller-1.1.yaml

wget https://gitee.com/CloudLemon/tekton-install/raw/master/ingress-argocd/ingress-nginx.yaml

2. 0 安装ingress

# 给需要安装的节点打上标签, 如果只安装一个就 ,就给你需要的节点 打上标签就行
kubectl label node master isIngress="true"
kubectl label node node01 isIngress="true"
kubectl label node node02 isIngress="true"

# 安装
kubectl  apply   -f ingress-controller-1.1.yaml


3、kubectl get pod -n ingress-nginx
NAME                                   READY   STATUS      RESTARTS      AGE
ingress-nginx-admission-create-dwm6c   0/1     Completed   0             39m
ingress-nginx-admission-patch-nf5sp    0/1     Completed   1             39m
ingress-nginx-controller-6hgb8         1/1     Running     7 (33m ago)   39m
ingress-nginx-controller-7mxrq         1/1     Running     0             39m
ingress-nginx-controller-8q9cq         1/1     Running     0             39m

如果遇到如下错误，请尝试如下解决方案

1、检查物理机80和443端口有没有被占用！！！！！
2、检查secret名字
2.1、节点是否被禁止调度
