NGINX lua集成kafka
第一步：进入opresty目录
[root@node03 openresty]# cd /export/servers/openresty/

[root@node03 openresty]#
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

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/

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

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);
}
}
/**

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！！！！！！！！
