1. 在服务器上部署mqtt服务

2.在宝塔上配置域名+证书

3.nginx配置websocket

server
{
    listen 80;
		listen 443 ssl http2;
    server_name ws-xx.example.com;
    index index.php index.html index.htm default.php default.htm default.html;
    root /www/wwwroot/ws-xx.example.com;
    
    location / {  
      proxy_pass http://ip地址:8084;
      proxy_http_version 1.1;
      proxy_set_header Upgrade websocket;
      proxy_set_header Connection "upgrade";
    }  

    #SSL-START SSL相关配置，请勿删除或修改下一行带注释的404规则
    #error_page 404/404.html;
    ssl_certificate    /www/server/panel/vhost/cert/ws-xx.example.com/fullchain.pem;
    ssl_certificate_key    /www/server/panel/vhost/cert/ws-xx.example.com/privkey.pem;
    ssl_protocols TLSv1.1 TLSv1.2 TLSv1.3;
    ssl_ciphers EECDH+CHACHA20:EECDH+CHACHA20-draft:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5;
    ssl_prefer_server_ciphers on;
    ssl_session_cache shared:SSL:10m;
    ssl_session_timeout 10m;
    add_header Strict-Transport-Security "max-age=31536000";
    error_page 497  https://$host$request_uri;


    #SSL-END

    #ERROR-PAGE-START  错误页配置，可以注释、删除或修改
    #error_page 404 /404.html;
    #error_page 502 /502.html;
    #ERROR-PAGE-END

    #PHP-INFO-START  PHP引用配置，可以注释或修改
    include enable-php-00.conf;
    #PHP-INFO-END

    #REWRITE-START URL重写规则引用,修改后将导致面板设置的伪静态规则失效
    include /www/server/panel/vhost/rewrite/ws-xx.example.com.conf;
    #REWRITE-END

    #禁止访问的文件或目录
    location ~ ^/(\.user.ini|\.htaccess|\.git|\.env|\.svn|\.project|LICENSE|README.md)
    {
        return 404;
    }

    #一键申请SSL证书验证目录相关设置
    location ~ \.well-known{
        allow all;
    }

    #禁止在证书验证目录放入敏感文件
    if ( $uri ~ "^/\.well-known/.*\.(php|jsp|py|js|css|lua|ts|go|zip|tar\.gz|rar|7z|sql|bak)$" ) {
        return 403;
    }

    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    {
        expires      30d;
        error_log /dev/null;
        access_log /dev/null;
    }

    location ~ .*\.(js|css)?$
    {
        expires      12h;
        error_log /dev/null;
        access_log /dev/null;
    }
    access_log  /www/wwwlogs/ws-xx.example.com.log;
    error_log  /www/wwwlogs/ws-xx.example.com.error.log;
}

4.登录mqtt控制台，配置监听器

只要配置证书和key即可，最最关键一点就是 验证服务器证书 这一处要关闭掉，否则导致wss连接失败

 5.打开网页客户端并配置连接：http://www.emqx.io/online-mqtt-client

 配置完毕点击 连接 即可。

k8s部署mqtt，使用ingress配置wss访问

kind: Ingress
apiVersion: networking.k8s.io/v1
metadata:
  name: mqtt
  namespace: mqtt
  annotations:
    kubesphere.io/alias-name: wss
    kubesphere.io/creator: admin
spec:
  ingressClassName: nginx
  tls:
    - hosts:
        - ws-xx.example.com
      secretName: example.com
  rules:
    - host: ws-xx.example.com
      http:
        paths:
          - path: /
            pathType: ImplementationSpecific
            backend:
              service:
                name: mqtt-service
                port:
                  number: 8084
