Nginx Lua集成Kafka

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

[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

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  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:

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",

        httpPost.setHeader("Time-Iso8601", getISO8601Timestamp());
        httpPost.setHeader("Server Address", "243.45.78.132");
        httpPost.setHeader(
                "Cookie",
                "JSESSIONID=782121159357B98CA6112554CF44321E; sid=b5cc11e02e154ac5b0f3609332f86803; aid=8ae8768760927e280160bb348bef3e12; identifyStatus=N; userType4logCookie=M; userId4logCookie=13818791413; useridCookie=13818791413; userCodeCookie=13818791413; temp_zh=cou%3D0%3Bsegt%3D%E5%8D%95%E7%A8%8B%3Btime%3D2018-01-13%3B%E5%B9%BF%E5%B7%9E-%E5%8C%97%E4%BA%AC%3B1%2C0%2C0%3B%26cou%3D1%3Bsegt%3D%E5%8D%95%E7%A8%8B%3Btime%3D"

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!

完毕!
