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：

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：

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.luakafkalua.lua:

end

-- 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 664 Jul 26 11:33 uwsgi_params.default
-rw-r--r-- 1 root root 3610 Jul 26 11:33 win-utf2. 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 nginx2. 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 le5. 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>

}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_COLLECTION12. 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！
