我无法使用http：//：30602和http：//：30602访问nginx服务器

操作系统：Ubuntu 22

我还检查了是否有防火墙阻止它。

使用ufw

admin@tst-server:~$ sudo ufw status verbose
Status: inactive

使用netstat

admin@tst-server:~$ netstat -an | grep 22 | grep -i listen
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN
tcp6       0      0 :::22                   :::*                    LISTEN
unix  2      [ ACC ]     STREAM     LISTENING     354787   /run/containerd/s/9a866c6ea3a4fe1976aaed0884400cd59228d43776774cc3fad2d0b9a7c2ed7b

admin@tst-server:~$ netstat -an | grep 30602 | grep -i listen

用于nginx部署的命令

创建部署

kubectl create deployment nginx --image=nginx
kubectl get deployments
NAME    READY   UP-TO-DATE   AVAILABLE   AGE
myapp   2/2     2            2           8d
nginx   1/1     1            1           9m50s

创建服务

kubectl create service nodeport nginx --tcp=80:80
kubectl get svc
NAME         TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)        AGE
kubernetes   ClusterIP   10.96.0.1        <none>        443/TCP        8d
nginx        NodePort    10.109.112.116   <none>        80:30602/TCP   10m

测试一下

admin@tst-server:~$ hostname
tst-server.com

admin@tst-server:~$ curl tst-server.com:30602
curl: (7) Failed to connect to tst-server.com port 30602 after 10 ms: Connection refused
