安装部署rancher2.7.0，然后导入K8S集群，管理集群

1. 安装rancher2.7.0

docker run -d  --name rancher --restart=unless-stopped --privileged   -p 80:80 -p 443:443   -v /var/lib/rancher:/var/lib/rancher/   -v /var/log/rancher/auditlog:/var/log/auditlog    rancher/rancher:v2.7.0

2.浏览器登录

2.1 利用默认账号登录

默认用户是admin

[root@k8s-master ~]# docker ps -a|grep rancher  #查看容器id
8df8025ff9a9   rancher/rancher:v2.7.0                              "entrypoint.sh"           About an hour ago   Up 33 minutes               0.0.0.0:80->80/tcp, :::80->80/tcp, 0.0.0.0:443->443/tcp, :::443->443/tcp   rancher
[root@k8s-master ~]# docker logs 8df8025ff9a9 2>&1 | grep "Bootstrap Password:" #查看密码
2023/07/14 10:18:06 [INFO] Bootstrap Password: ssv7dp6gm29k69rbwqz9cmgrm6t7b8pthk2tmwdcwxrv86jktxhm9c
[root@k8s-master ~]# 

2.2 登录地址是 rancher机器IP

2.3 设置管理员账号

具体操作忽略，是点击右上角的头像，然后点击 账号API密钥，在里面添加账号和密码，选择管理员就可以了。

3. rancher2.7.0导入集群

#######复制在内容在master上执行
[root@k8s-master ~]# curl --insecure -sfL https://192.168.186.128/v3/import/wg9vkxjm94skp872zpm9nxmqz6rz8jjrn88prcvwvvdjkrwk6bhln9_c-m-5jcxgvql.yaml | kubectl apply -f -

service/cattle-cluster-agent created
[root@k8s-master ~]# 

4.验证rancher管理集群成功

5.利用rancher部署一个nginx服务

6.验证nginx 容器是否可以访问

###########用命令查看是否一致
[root@k8s-master ~]# kubectl get pods,svc
NAME                         READY   STATUS    RESTARTS   AGE
pod/nginx-5f7bd866f7-gk6vc   1/1     Running   0          3m51s

NAME                     TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)        AGE
service/kubernetes       ClusterIP   10.96.0.1        <none>        443/TCP        39d
service/nginx            ClusterIP   10.99.120.118    <none>        80/TCP         3m51s
service/nginx-nodeport   NodePort    10.104.209.103   <none>        80:30905/TCP   3m51s
[root@k8s-master ~]# 

[root@k8s-master ~]# kubectl get nodes -o wide
NAME         STATUS   ROLES                  AGE   VERSION   INTERNAL-IP       EXTERNAL-IP   OS-IMAGE                KERNEL-VERSION           CONTAINER-RUNTIME
k8s-master   Ready    control-plane,master   39d   v1.23.8   192.168.186.128   <none>        CentOS Linux 7 (Core)   3.10.0-1160.el7.x86_64   docker://24.0.2
k8s-node1    Ready    <none>                 39d   v1.23.8   192.168.186.129   <none>        CentOS Linux 7 (Core)   3.10.0-1160.el7.x86_64   docker://24.0.2
[root@k8s-master ~]# 

利用集群的任何一个IP:30905,在浏览器中是可以访问的 即 192.168.186.128:30905 192.168.186.129:30905

到这里就安装成功了，欢迎大家有问题留言。
