nginx lua集成kafka的实现方法

(编辑：jimmy 日期: 2024/11/18 浏览：3 次 )

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

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

"htmlcode">

[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

drwxr-xr-x 2 root root 4096 Jul 26 11:33 dns
drwxr-xr-x 2 root root 4096 Aug 1 10:42 kafka  #这是我们自己导入的
drwxr-xr-x 2 root root 4096 Jul 26 11:33 limit

drwxr-xr-x 2 root root 4096 Jul 26 11:33 upstream
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 "hljs-comment">#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",

    httpPost.setHeader("Remote Address", "192.168.56.80");
    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：
