在nginx这一层,接收到访问请求的时候,就把请求的流量上报发送给kafka
storm才能去消费kafka中的实时的访问日志,然后去进行缓存热数据的统计
从lua脚本直接创建一个kafka producer,发送数据到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脚本:
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
两台机器上都这样做,才能统一上报流量到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上的节点死掉了,可能是虚拟机的问题,杀掉进程,重新启动一下
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,重启三个kafka进程
(4)需要启动eshop-cache缓存服务,因为nginx中的本地缓存可能不在了
