    nginx lua集成kafka的实现方法

    第一步:进入opresty目录

    [root@node03 openresty]# cd /export/servers/openresty/
    [root@node03 openresty]# ll
    total 356
    drwxr-xr-x 2 root root  4096 Jul 26 11:33 bin

    -rw-r--r-- 1 root root 218352 Jul 26 11:33 resty.index
    drwxr-xr-x 5 root root  4096 Jul 26 11:33 site
    drwxr-xr-x 2 root root  4096 Aug 1 10:54 testlua
    drwxrwxr-x 2 1000 1000  4096 Nov 13 2017 util
    [root@node03 openresty]# 
    

    说明:接下来我们关注两个目录 lualib 和 nginx

    1.lualib: 是存放opresty所需要的集成软件包的

    2.nginx: 是nginx服务目录

    接下来,我们进入lualib目录一看究竟:

    [root@node03 openresty]# cd lualib/
    [root@node03 lualib]# ll
    total 116
    -rwxr-xr-x 1 root root 101809 Jul 26 11:33 cjson.so
    drwxr-xr-x 3 root root  4096 Jul 26 11:33 ngx
    drwxr-xr-x 2 root root  4096 Jul 26 11:33 rds
    drwxr-xr-x 2 root root  4096 Jul 26 11:33 redis
    drwxr-xr-x 9 root root  4096 Aug 1 10:34 resty
    

    这里我们看到了redis和ngx集成软件包,说明我们可以之间使用nginx和redis而无需导入任何依赖包!!!!

    下面看看resty里面有些说明呢????

    [root@node03 lualib]# cd resty/
    [root@node03 resty]# ll
    total 152
    -rw-r--r-- 1 root root 6409 Jul 26 11:33 aes.lua

    -rw-r--r-- 1 root root 1221 Jul 26 11:33 sha256.lua
    -rw-r--r-- 1 root root 1045 Jul 26 11:33 sha384.lua
    -rw-r--r-- 1 root root 1359 Jul 26 11:33 sha512.lua

    drwxr-xr-x 2 root root 406 Jul 26 11:33 websocket
    

    这里我们看到了熟悉的mysql.lua和redis.lua,好了其他的先不要管

    注意:这里的 kafka 这个包是没有的,说明opnresty么有集成kafka。此处我已经提前导入啦kafka集成包

    我们看看kafka里面多有哪些包:

    [root@node03 resty]# cd kafka
    [root@node03 kafka]# ll
    total 48
    -rw-r--r-- 1 root root 1369 Aug 1 10:42 broker.lua
    -rw-r--r-- 1 root root 5537 Aug 1 10:42 client.lua
    -rw-r--r-- 1 root root  710 Aug 1 10:42 errors.lua
    -rw-r--r-- 1 root root 10718 Aug 1 10:42 producer.lua
    -rw-r--r-- 1 root root 4072 Aug 1 10:42 request.lua
    -rw-r--r-- 1 root root 2118 Aug 1 10:42 response.lua
    -rw-r--r-- 1 root root 1494 Aug 1 10:42 ringbuffer.lua
    -rw-r--r-- 1 root root 4845 Aug 1 10:42 sendbuffer.lua
    

    附上 kafka 集成包:kafka_jb51.rar

    第二步:创建kafka测试lua文件

    1.退回到openresty

    [root@node03 kafka]# cd /export/servers/openresty/

    2.创建测试文件

    [root@node03 openresty]# mkdir -r testlua
    #这里文件名自己取,文件位置自己定,但必须找得到

    这里文件名自己取,文件位置自己定,但必须找得到!!!!!!!!!!!下面会用到!!!!!!!!!!

    3.进入刚刚创建的文件夹并创建kafkalua.lua脚本文件

    创建文件:vim kafkalua.lua或者touch kafkalua.lua

    [root@node03 openresty]# cd testlua/
    [root@node03 testlua]# ll
    total 8
    -rw-r--r-- 1 root root 3288 Aug 1 10:54 kafkalua.lua

    kafkalua.lua:

    --测试语句可以不用
    ngx.say('hello kafka file configuration successful!!!!!!')
    
    --数据采集阈值限制,如果lua采集超过阈值,则不采集
    local DEFAULT_THRESHOLD = 100000
    -- kafka分区数
    local PARTITION_NUM = 6
    -- kafka主题名称
    local TOPIC = 'B2CDATA_COLLECTION1'
    -- 轮询器共享变量KEY值
    local POLLING_KEY = "POLLING_KEY"
    -- kafka集群(定义kafka broker地址,ip需要和kafka的host.name配置一致)
    local function partitioner(key, num, correlation_id)
      return tonumber(key)
    end
    --kafka broker列表
    local BROKER_LIST = {{host="192.168.52.100",port=9092},{host="192.168.52.110",port=9092},{host="192.168.52.120",port=9092}}
    --kafka参数,
    local CONNECT_PARAMS = { producer_type = "async", socket_timeout = 30000, flush_time = 10000, request_timeout = 20000, partitioner = partitioner }
    -- 共享内存计数器,用于kafka轮询使用
    local shared_data = ngx.shared.shared_data
    local pollingVal = shared_data:get(POLLING_KEY)
    if not pollingVal then
      pollingVal = 1
      shared_data:set(POLLING_KEY, pollingVal)
    end
    --获取每一条消息的计数器,对PARTITION_NUM取余数,均衡分区
    local partitions = '' .. (tonumber(pollingVal) % PARTITION_NUM)
    shared_data:incr(POLLING_KEY, 1)
    
    -- 并发控制
    local isGone = true
    --获取ngx.var.connections_active进行过载保护,即如果当前活跃连接数超过阈值进行限流保护
    if tonumber(ngx.var.connections_active) > tonumber(DEFAULT_THRESHOLD) then
      isGone = false
    end
    -- 数据采集
    if isGone then
    
      local time_local = ngx.var.time_local
      if time_local == nil then
        time_local = ""
      end
    
      local request = ngx.var.request
      if request == nil then
        request = ""
      end
    
      local request_method = ngx.var.request_method
      if request_method == nil then
        request_method = ""
      end
    
      local content_type = ngx.var.content_type
      if content_type == nil then
        content_type = ""
      end
      ngx.req.read_body()
      local request_body = ngx.var.request_body
      if request_body == nil then
        request_body = ""
      end
    
      local http_referer = ngx.var.http_referer
      if http_referer == nil then
        http_referer = ""
      end
    
      local remote_addr = ngx.var.remote_addr
      if remote_addr == nil then
        remote_addr = ""
      end
    
      local http_user_agent = ngx.var.http_user_agent
      if http_user_agent == nil then
        http_user_agent = ""
      end
    
      local time_iso8601 = ngx.var.time_iso8601
      if time_iso8601 == nil then
        time_iso8601 = ""
      end
    
      local server_addr = ngx.var.server_addr
      if server_addr == nil then
        server_addr = ""
      end
    
      local http_cookie = ngx.var.http_cookie
      if http_cookie == nil then
        http_cookie = ""
      end
    --封装数据
      local message = time_local .."#CS#".. request .."#CS#".. request_method .."#CS#".. content_type .."#CS#".. request_body .."#CS#".. http_referer .."#CS#".. remote_addr .."#CS#".. http_user_agent .."#CS#".. time_iso8601 .."#CS#".. server_addr .."#CS#".. http_cookie;
    --引入kafka的producer
    local producer = require "resty.kafka.producer"
    --创建producer
    local bp = producer:new(BROKER_LIST, CONNECT_PARAMS)
    --发送数据
    local ok, err = bp:send(TOPIC, partitions, message)
    --打印错误日志
      if not ok then
        ngx.log(ngx.ERR, "kafka send err:", err)
        return
      end
    end
    

    第三步:修改nginx配置文件nginx.conf

    1.进入ngin/conf目录

    [root@node03 openresty]# cd /export/servers/openresty/nginx/conf/
    [root@node03 conf]# ll
    total 76
    -rw-r--r-- 1 root root 1077 Jul 26 11:33 fastcgi.conf
    -rw-r--r-- 1 root root 1077 Jul 26 11:33 fastcgi.conf.default
    -rw-r--r-- 1 root root 1007 Jul 26 11:33 fastcgi_params
    -rw-r--r-- 1 root root 1007 Jul 26 11:33 fastcgi_params.default
    -rw-r--r-- 1 root root 2837 Jul 26 11:33 koi-utf
    -rw-r--r-- 1 root root 2223 Jul 26 11:33 koi-win
    -rw-r--r-- 1 root root 5170 Jul 26 11:33 mime.types
    -rw-r--r-- 1 root root 5170 Jul 26 11:33 mime.types.default
    -rw-r--r-- 1 root root 3191 Aug 1 10:52 nginx.conf
    -rw-r--r-- 1 root root 2656 Jul 26 11:33 nginx.conf.default
    -rw-r--r-- 1 root root 636 Jul 26 11:33 scgi_params
    -rw-r--r-- 1 root root 636 Jul 26 11:33 scgi_params.default
    -rw-r--r-- 1 root root 664 Jul 26 11:33 uwsgi_params
    -rw-r--r-- 1 root root 664 Jul 26 11:33 uwsgi_params.default
    -rw-r--r-- 1 root root 3610 Jul 26 11:33 win-utf
    
    

    2.修改nginx.conf

    [root@node03 conf]# vim nginx.conf
    
        #1.说明找到第一个server
        #2.在server上面添加两行代码如下
        #3.在server里面添加kafka相关的代码如下
        
        
    #------------------添加的代码---------------------------------------
     #开启共享字典,设置内存大小为10M,供每个nginx的线程消费
     lua_shared_dict shared_data 10m;
     #配置本地域名解析
     resolver 127.0.0.1;
    #------------------添加的代码---------------------------------------
    
     server {
        listen    80;
        server_name localhost;
    
        #charset koi8-r;
    
        #access_log logs/host.access.log main;
        location / {
          root  html;
          index index.html index.htm;
        }
    
        #------------------添加的代码---------------------------------------
        location /kafkalua { #这里的kafkalua就是工程名字,不加默认为空
          #开启nginx监控
          stub_status on;
          #加载lua文件
          default_type text/html;
          #指定kafka的lua文件位置,就是我们刚才创建的kafkalua.lua(前面已经强调要记住的!!!!)
          content_by_lua_file /export/servers/openresty/testlua/kafkalua.lua;
        }
        #------------------添加的代码---------------------------------------
    }

    说明:location /kafkalua{...}这里的kafkalua是工程名,可以随意取也可以不取,但是必须要记住!!!

    看到我们上面配置了两个location,第一个为location /{...}第二个为location /kafkalua{...}那么他们有什么区别呢???先向下看,迷雾将会慢慢揭开。

    第四步:启动nginx

    1.进入nginx/sbin

    [root@node03 sbin]# cd /export/servers/openresty/nginx/sbin/
    [root@node03 sbin]# ll
    total 16356
    -rwxr-xr-x 1 root root 16745834 Jul 26 11:33 nginx
    

    2.测试配置文件是否正确

    [root@node03 sbin]# nginx -t
    nginx: the configuration file /export/servers/openresty/nginx/conf/nginx.conf syntax is ok
    nginx: configuration file /export/servers/openresty/nginx/conf/nginx.conf test is successful
    #看到已经成功啦

    3.启动nginx

    [root@node03 sbin]# nginx
    #不显示任何东西一般是成功啦

    4.查看nginx是否启动成功

    [root@node03 sbin]# ps -ef | grep nginx
    root    3730   1 0 09:24 ?    00:00:00 nginx: master process nginx
    nobody   3731  3730 0 09:24 ?    00:00:20 nginx: worker process is shutting down
    nobody   5766  3730 0 12:17 ?    00:00:00 nginx: worker process
    root    5824  3708 0 12:24 pts/1  00:00:00 grep nginx
    #看到有两个nginx进程,表示成功le
    

    5.浏览器访问nginx

    在浏览器输入:node03/kafkalua

    说明:如何么有配置hosts则输入openresty所在设备的地址如:192.168.52.120/kafkalua

    在浏览器输入:node03/或者 192.168.52.120/

    再在浏览器输入:node03:80/kafkalua 和 node03:80/试试 搬来nginx.conf来看看:

    node03:80/kafkalua 这里的nide03是服务器的别名或者之间写文服务器地址,80是【listen 80;】配置的监听端口,80端口可以省略不写,如果这写成【listen 8088;】那么浏览器需输入 node03:8088/kafkalua (这里不能省略8088),kafkalua是工程名。

     server {
        listen    80;
        server_name localhost;
    
        #charset koi8-r;
    
        #access_log logs/host.access.log main;
        location / {
          root  html;
          index index.html index.htm;
        }
    
        #------------------添加的代码---------------------------------------
        location /kafkalua { #这里的kafkalua就是工程名字,不加默认为空
          #开启nginx监控
          stub_status on;
          #加载lua文件
          default_type text/html;
          #指定kafka的lua文件位置,就是我们刚才创建的kafkalua.lua(前面已经强调要记住的!!!!)
          content_by_lua_file /export/servers/openresty/testlua/kafkalua.lua;
        }

    第五步:创建测试爬虫程序

    1.创建maven工程导入依赖

     <dependencies>
        <dependency>
          <groupId>org.jsoup</groupId>
          <artifactId>jsoup</artifactId>
          <version>1.11.3</version>
        </dependency>
        <dependency>
          <groupId>org.apache.httpcomponents</groupId>
          <artifactId>httpclient</artifactId>
          <version>4.5.4</version>
        </dependency>
      </dependencies>

    2.伪爬虫程序

    public class SpiderGoAirCN {
      private static String basePath = "http://node03/kafkalua";
      public static void main(String[] args) throws Exception {
        for (int i = 0; i < 50000; i++) {
          // 请求查询信息
          spiderQueryao();
          // 请求html
          spiderHtml();
          // 请求js
          spiderJs();
          // 请求css
          spiderCss();
          // 请求png
          spiderPng();
          // 请求jpg
          spiderJpg();
          Thread.sleep(100);
        }
      }
    
      /**
       * 
       * @throws Exception
       */
      public static void spiderQueryao() throws Exception {
        // 1.指定目标网站   ^.*/B2C40/query/jaxb/direct/query.ao.*$
        String url = basePath + "/B2C40/query/jaxb/direct/query.ao";
        // 2.发起请求
        HttpPost httpPost = new HttpPost(url);
        // 3. 设置请求参数
        httpPost.setHeader("Time-Local", getLocalDateTime());
        httpPost.setHeader("Requst",
              "POST /B2C40/query/jaxb/direct/query.ao HTTP/1.1");
        httpPost.setHeader("Request Method", "POST");
        httpPost.setHeader("Content-Type",
            "application/x-www-form-urlencoded; charset=UTF-8");
        httpPost.setHeader(
            "Referer",
            "http://b2c.csair.com/B2C40/modules/bookingnew/main/flightSelectDirect.html?t=S&c1=CAN&c2=WUH&d1="
                + getGoTime() + "&at=1&ct=0&it=0");
        httpPost.setHeader("Remote Address", "192.168.56.80");
        httpPost.setHeader(
            "User-Agent",
            "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36");
        httpPost.setHeader("Time-Iso8601", getISO8601Timestamp());
        httpPost.setHeader("Server Address", "243.45.78.132");
        httpPost.setHeader(

    第六步:启动kafka

    1.创建主题topic

    [root@node01 bin]# kafka-topics.sh --zookeeper node01:2181 --partitions 3 
    --replication-factor 3 --create --topic B2CDATA_COLLECTION1
    

    2.开启kafka消费者

    [root@node01 bin]# kafka-console-consumer.sh --bootstrap-server node01:9092,node02:9092,node03:9092 
    --topic B2CDATA_COLLECTION1
    

    第七步:开启爬虫程序并观察结果

    1.启动爬虫程序

    2.观察消费者窗口如下

    第八步:启动kafka-manager观察

    1.启动kafka-manager

    [root@node01 conf]# cd /export/servers/kafka-manager-1.3.3.23/bin/
    [root@node01 bin]# ll
    total 36
    -rwxr-xr-x 1 root root 13747 May 1 06:27 kafka-manager
    -rw-r--r-- 1 root root 9975 May 1 06:27 kafka-manager.bat
    -rwxr-xr-x 1 root root 1383 May 1 06:27 log-config
    -rw-r--r-- 1 root root  105 May 1 06:27 log-config.bat
    [root@node01 bin]# 
    
    #启动
    [root@node01 bin]# ./kafka-manager 
    

    启动后的窗口:

    2.浏览器访问

    浏览器输入:node01:9000

    kafka manager使用不做讲解,观察B2CDATA_COLLECTION1主题消费情况:

    ​ 有三个分区,每个分区消费的消息差多说明成功啦,

    ​ 如果不一样,则是kafkalua.lua 脚本中没有配置分区策略,默认分区会导致 数据倾斜 我们需配置自己的分区策略!

    以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持脚本之家。
