介绍

这是一个基于Netty框架二次封装的高性能Http接口服务，增加了对http请求路由的功能，当初设计的初衷是将接收到的日志经过简单处理后快速推送到kafka ，服务于易企秀数据埋点业务，目前春节期间日处理10亿+ ；目前该项目已把业务剥离、并简化了操作，大家可放心使用。

特点：简单、高效 （在最普通的机器环境压测QPS最高可以达到2.5w/s）

设计

依赖

• Netty4
• logback kafka appender
• ipip

快速启动

1、编译

git clone https://github.com/yanchaoguo/log-server.git

mvn assembly:assembly

2、配置 将编译好的工程放到 /data/work/log_server，目录结构如下：

----log_server
          |
          ----bin           #依赖的jar包
          |
          ----classes       #编译后生成的classes目录
          |
          ----bin           #启动脚本
          |
          ----logs          #日志文件  

cd /data/work/log_server/bin 编辑 ls.sh 脚本，配置端口号和kafka地址

port=9001
kafka=hadoop006:9092,hadoop007:9092,hadoop008:9092

3、启动

./ls.sh start

快速开发

1、目录说明

2、在action目录下新增业务处理类，比如创建FastPushAction并实现Action接口的doAction方法；该类不对日志进行处理，没有太多业务逻辑，负责将接收到的日志发送到kafka ，可以作为demo参考，具体实现如下

/**
 * /fast_push为该业务逻辑的请求路径 ，如http://localhost:port/log-server/fast_push
 */
@Route(value = "/fast_push")
public class FastPushAction implements Action {

    private static final Logger logger = LoggerFactory.getLogger(PushLogAction.class);


    @Override
    public void doAction(Request request, Response response) {

            String logs = request.getContent();  //从body中获取日志内容
            //从参数中获取 logger 名称，为空则取默认值
            String loger = Utils.isNulDefault(request.getParam("loger"),LogConfigManager.trashTopic);

            int responseStatus = CodeManager.RESPONSE_CODE_NORMAL;

            //如果body中没有内容 尝试从url参数中获取
            if (StrUtil.isEmpty(logs) && request.getParams().size()>0) {
                logs = Utils.toJson(request.getParams());
            }
            if (StrUtil.isEmpty(logs)) {
                response.setContent("<h2>not find log content</h2>");
                responseStatus = CodeManager.RESPONSE_CODE_NOT_CONTENT;
                logger.warn("not find log content");
            }else {
                //将日志推送到kafka，其中 logger 的名称要和logback.xml中的配置一致
                KafkaLoggerFactory.getLogger(loger).info(logs);
            }
            // 设置返回信息：
            response.setStatus(responseStatus);
            response.setHeader("Access-Control-Allow-Origin", "*");
            response.setHeader(CookieHeaderNames.EXPIRES , -1);
            // 返回：
            response.send();

    }

}

3、配置logback.xml

<?xml version="1.0" encoding="UTF-8" ?>
<configuration>
    <!--trash-->
    <logger name="trash" level="INFO" additivity="false">
        <appender-ref ref="trash_kafka"/>
    </logger>


  <appender name="trash_kafka" class="com.github.danielwegener.logback.kafka.KafkaAppender">
        <encoder class="com.github.danielwegener.logback.kafka.encoding.LayoutKafkaMessageEncoder">
            <layout class="ch.qos.logback.classic.PatternLayout">
                <pattern>%msg</pattern>
            </layout>
            <charset>UTF-8</charset>
        </encoder>
        <topic>trash</topic>
        <keyingStrategy class="com.github.danielwegener.logback.kafka.keying.RoundRobinKeyingStrategy" />
        <deliveryStrategy class="com.github.danielwegener.logback.kafka.delivery.AsynchronousDeliveryStrategy" />
    	<producerConfig>bootstrap.servers=${kafka.servers}
        </producerConfig>
        <producerConfig>linger.ms=1000</producerConfig>
        <producerConfig>compression.type=none</producerConfig>
        <producerConfig>buffer.memory=1073741842</producerConfig>
        <producerConfig>acks=1</producerConfig>
   </appender>
</configuration>

4、在 LogServer.java 中注册FastPushAction

 public static void start() {
        //注册action
        ServerSetting.setAction(PushLogAction.class);
        ServerSetting.setAction(FastPushAction.class);
        try {
            new LogServer().start(ServerSetting.getPort());
        } catch (InterruptedException e) {
            log.error("LoServer start error!", e);
        }
    }

性能
