ngx_kafka_module安装与使用

【安装】

ngx_kafka_module网址:https://github.com/brg-liuwei/ngx_kafka_module

1、安装git

  yum install -y git

2、下载ngx_kafka_module依赖librdkafka(kafka的c客户端源码)

  cd /usr/local/src

  git clone https://github.com/edenhill/librdkafka

3、编译与安装ngx_kafka_module依赖librdkafka

  cd /usr/local/src/librdkafka

  ./configure

  make && make install

4、下载ngx_kafka_module

  cd /usr/local/src

  git clone https://github.com/brg-liuwei/ngx_kafka_module

5、下载nginx,本次下载的nginx版本为:nginx-1.18.0.tar.gz 下载地址

6、上传至服务器并解压:tar -zxvf nginx-1.18.0.tar.gz -C /usr/local

7、编译nginx

  cd cd /usr/local/nginx-1.18.0/

  ./configure --add-module=/usr/local/src/ngx_kafka_module

8、安装nginx

  make && make install

9、将nginx添加到环境变量。编辑/etc/profile,在末尾加上如下内容

export NGINX_HOME=/usr/local/nginx
export PATH=$PATH:$NGINX_HOME/sbin

      source /etc/profile

10、启动nginx:nginx

  如果启动报如下错误 

nginx: error while loading shared libraries: librdkafka.so.1: cannot open shared object file: No such file or directory

  则需要添加so库

  echo "/usr/local/lib" >> /etc/ld.so.conf

  ldconfig

【使用】

1、启动kafka

  kafka的安装与启动

 

2、创建主题

  kafka-topics.sh --zookeeper localhost:2181/kafka --create --topic tp_ngx_kafka --partitions 1 --replication-factor 1

3、修改nginx配置文件

  编辑nginx.conf文件(vim /usr/local/nginx/conf/nginx.conf),在http模块内添加如下内容

  kafka;

  #kafka broker地址,多个地址以空格分隔开,替换成自己的broker地址

  kafka_broker_list 192.168.3.52:9092;

include /usr/local/nginx/conf/conf.d/*.conf;

  创建conf.d文件夹:mkdir /usr/local/nginx/conf/conf.d

       创建ngx-kafka-module.conf文件(vim /usr/local/nginx/conf/conf.d/ngx-kafka-module.conf),添加如下内容

server {
  listen   80;
#监听的域名,替换成自己的域名 server_name kafka.test.com; location
/ { kafka_topic tp_ngx_kafka; } }

4、重新加载nginx配置文件

  nginx -s reload

 至此,ngx-kafka-module配置完成,下面我们做个示例,来演示

5、编写html文件(index.html)。(注入引入jquery,这里我就不贴了,注意修改请求地址)

<!DOCTYPE html>
<html lang="zh-CN">
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>职位浏览</title>
        <script type="text/javascript" src="js/jquery-3.4.1.min.js"></script>
    </head>
    <body>
        <table>
            <tr>
                <th>职位</th>
                <th>企业</th>
                <th>薪资</th>
                <th>操作</th>
            </tr>
            <tr>
                <td>开发</td>
                <td>阿里</td>
                <td>10000</td>
                <td>
                    <button onclick="operation('A001', 'click')">点击</button>
                    <button onclick="operation('A001', 'job_collect')">收藏</button>
                    <button onclick="operation('A001', 'cv_send')">投递简历</button>
                    <button onclick="operation('A001', 'cv_upload')">上传简历</button>
                </td>
            </tr>
            <tr>
                <td>开发</td>
                <td>腾讯</td>
                <td>20000</td>
                <td>
                    <button onclick="operation('A002', 'click')">点击</button>
                    <button onclick="operation('A002', 'job_collect')">收藏</button>
                    <button onclick="operation('A002', 'cv_send')">投递简历</button>
                    <button onclick="operation('A002', 'cv_upload')">上传简历</button>
                </td>
            </tr>
            <tr>
                <td>开发</td>
                <td>拉勾</td>
                <td>30000</td>
                <td>
                    <button onclick="operation('A003', 'click')">点击</button>
                    <button onclick="operation('A003', 'job_collect')">收藏</button>
                    <button onclick="operation('A003', 'cv_send')">投递简历</button>
                    <button onclick="operation('A003', 'cv_upload')">上传简历</button>
                </td>
            </tr>
        </table>
    </body>

    <script>
        

        function operation(job_code,action) {
            $.ajax({
                url: 'http://kafka.test.com/',
                type: 'POST',
                contentType: 'application/json;charset=utf-8',
                dataType: 'json',
                data:{
                  user_id:101,
                  act_time:  new Date().getTime(),
                  action:action,
                  job_code:job_code
                },
                success: function (data) {

                }
            })
        }
    </script>
</html>
View Code

6、上传index.html到服务器

  #创建h5目录

  mkdir -p /www/wwwroot/kafka

  cd /www/wwwroot/kafka

  #上传文件

  rz -y

7、配置nginx

  vim /usr/local/nginx/conf/conf.d/h5-test.conf 

server {
  listen   80;
  server_name h5.test.com;

  location / {
     root /www/wwwroot/kafka/;
     index index.html;
  }
}

  nginx -s reload

8、访问h5.test.com

  

 

 

  点击按钮,跨域了

9、解决跨域问题

  编辑ngx-kafka-module.conf文件(vim /usr/local/nginx/conf/conf.d/ngx-kafka-module.con),在location模块下添加如下内容

     add_header Access-Control-Allow-Origin *;
     add_header Access-Control-Allow-Methods 'GET,POST';
     add_header Access-Control-Allow-Headers 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';

  nginx重新加载配置文件:nginx -s reload

10、启动kafka控制台消费者

  kafka-console-consumer.sh --bootstrap-server 192.168.3.52:9092 --topic tp_ngx_kafka

11、页面点击按钮,在kafka控制台收到消息

  

 

 至此验证完毕
