nginx+lua訪問流量實時上報kafka

在nginx這一層，接收到訪問請求的時候，就把請求的流量上報發送給kafka

storm才能去消費kafka中的實時的訪問日志，然后去進行緩存熱數據的統計

從lua腳本直接創建一個kafka producer，發送數據到kafka

wget https://github.com/doujiang24/lua-resty-kafka/archive/master.zip

yum install -y unzip

unzip lua-resty-kafka-master.zip

cp -rf /usr/local/lua-resty-kafka-master/lib/resty /usr/hello/lualib
nginx -s reload

　　lua腳本：

local cjson = require("cjson")  
local producer = require("resty.kafka.producer")  

local broker_list = {  
    { host = "192.168.31.187", port = 9092 },  
    { host = "192.168.31.19", port = 9092 },  
    { host = "192.168.31.227", port = 9092 }
}

local log_json = {}  
log_json["headers"] = ngx.req.get_headers()  
log_json["uri_args"] = ngx.req.get_uri_args()  
log_json["body"] = ngx.req.read_body()  
log_json["http_version"] = ngx.req.http_version()  
log_json["method"] =ngx.req.get_method() 
log_json["raw_reader"] = ngx.req.raw_header()  
log_json["body_data"] = ngx.req.get_body_data()  

local message = cjson.encode(log_json);  

local productId = ngx.req.get_uri_args()["productId"]

local async_producer = producer:new(broker_list, { producer_type = "async" })   
local ok, err = async_producer:send("access-log", productId, message)  

if not ok then  
    ngx.log(ngx.ERR, "kafka send err:", err)  
    return  
end

　　

兩台機器上都這樣做，才能統一上報流量到kafka

bin/kafka-topics.sh --zookeeper 192.168.31.187:2181,192.168.31.19:2181,192.168.31.227:2181 --topic access-log --replication-factor 1 --partitions 1 --create

bin/kafka-console-consumer.sh --zookeeper 192.168.31.187:2181,192.168.31.19:2181,192.168.31.227:2181 --topic access-log --from-beginning

（1）kafka在187上的節點死掉了，可能是虛擬機的問題，殺掉進程，重新啟動一下

nohup bin/kafka-server-start.sh config/server.properties &

（2）需要在nginx.conf中，http部分，加入resolver 8.8.8.8;

（3）需要在kafka中加入advertised.host.name = 192.168.31.187，重啟三個kafka進程

（4）需要啟動eshop-cache緩存服務，因為nginx中的本地緩存可能不在了

 

基於storm+kafka完成商品訪問次數實時統計拓撲的開發：
總結思路：

1、kafka consumer spout

單獨的線程消費，寫入隊列

nextTuple，每次都是判斷隊列有沒有數據，有的話再去獲取並發射出去，不能阻塞

2、日志解析bolt

3、商品訪問次數統計bolt

4、基於LRUMap完成統計

　　於雙重zookeeper分布式鎖完成分布式並行緩存預熱：

1、服務啟動的時候，進行緩存預熱

2、從zk中讀取taskid列表

3、依次遍歷每個taskid，嘗試獲取分布式鎖，如果獲取不到，快速報錯，不要等待，因為說明已經有其他服務實例在預熱了

4、直接嘗試獲取下一個taskid的分布式鎖

5、即使獲取到了分布式鎖，也要檢查一下這個taskid的預熱狀態，如果已經被預熱過了，就不再預熱了

6、執行預熱操作，遍歷productid列表，查詢數據，然后寫ehcache和redis

7、預熱完成后，設置taskid對應的預熱狀態
