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，并简化了操作，目的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，春节期间日处理10亿+
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）
项目地址：https://github.com/eqxiu/log-server
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("not find log content
");
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
%msg
UTF-8
trash
bootstrap.servers=${kafka.servers}
linger.ms=1000
compression.type=none
buffer.memory=1073741842
acks=1
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);
}
}
