zookeeper+kafka+logstash+elasticsearc+kibana

研究背景

1、之所以选用kafka是因为量起来的话单台logstash的抗压能力比较差

2、为了解决整个链路查询的问题，多个Feign传层的话，可以按照一个ID进行穿层，所以采用logback的MDC进行对唯一标识存储并且在Feign的调用链放在Header里，这里命名为TID

在拦截器里增加相对应的拦截代码

@Component
@Slf4j
public class ContextInterceptor implements HandlerInterceptor {RequestContext context = RequestContext.getCurrentContext();context.reset();log.debug("traceId:" + MDC.get("traceId"));String requestId = MDC.get("traceId");requestId = StringUtils.isEmpty(requestId) ? request.getHeader(RequestContext.REQUEST_ID) : requestId;requestId = StringUtils.isEmpty(requestId) ? request.getParameter(RequestContext.REQUEST_ID) : requestId;requestId = StringUtils.isEmpty(requestId) ? UUIDUtil.uuid() : requestId;MDC.put("TID", requestId);}

配置日志配置文件logback-spring.xml

%boldYellow(${module}) ：黄色的模块名称

%d ：日期时间

%highlight(%-5level)：高亮的日志级别，如info error trace登

%X{TID} : traceID 追踪使用的ID

%cyan(%logger{15}) :简写类名路径

%msg %n :具体日志信息

打印出来的效果如下：

配置zk+kafka

1. 安装JDK

1.1 安装文件：http://www.oracle.com/technetwork/java/javase/downloads/index.html 下载JDK
1.2 安装完成后需要添加以下的环境变量（右键点击“我的电脑” -> "高级系统设置" -> "环境变量" ）：

JAVA_HOME: C:\Program Files\Java\jdk1.8.0_171 (jdk的安装路径)

Path: 在现有的值后面添加"; %JAVA_HOME%\bin"

1.3 打开cmd运行 "java -version" 查看当前系统Java的版本：

2. 安装ZOOKEEPER

Kafka的运行依赖于Zookeeper，所以在运行Kafka之前我们需要安装并运行Zookeeper

2.1 下载安装文件： http://zookeeper.apache.org/releases.html

2.2 解压文件

2.3 打开zookeeper-3.4.13\conf，把zoo_sample.cfg重命名成zoo.cfg

2.6 添加如下系统变量：

ZOOKEEPER_HOME: C:\Users\localadmin\CODE\zookeeper-3.4.13 (zookeeper目录)
Path: 在现有的值后面添加 ";%ZOOKEEPER_HOME%\bin;"

2.7 运行Zookeeper: 打开cmd然后执行 zkserver

cmd 窗口不要关闭

3. 安装并运行KAFKA

3.1 下载安装文件： http://kafka.apache.org/downloads.html

3.2 解压文件

3.3 打开kafka_2.11-2.0.0\config

3.4 从文本编辑器里打开 server.properties

3.5 把 log.dirs的值改成 “./logs”

3.6 打开cmd

3.7 进入kafka文件目录: cd C:\Users\localadmin\CODE\kafka_2.11-2.0.0(kafka目录)

3.8 输入并执行: .\bin\windows\kafka-server-start.bat .\config\server.properties

cmd 窗口不要关闭

4. 创建TOPICS

4.1 打开cmd 并进入cd C:\Users\localadmin\CODE\kafka_2.11-2.0.0\bin\windows

4.2 创建一个topic： kafka-topics.bat --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test

5. 打开一个PRODUCER：

cd C:\Users\localadmin\CODE\kafka_2.11-2.0.0\bin\windows

kafka-console-producer.bat --broker-list localhost:9092 --topic test

6. 打开一个CONSUMER:

cd C:\Users\localadmin\CODE\kafka_2.11-2.0.0\bin\windows

kafka-console-consumer.bat --bootstrap-server localhost:9092 --topic test --from-beginning

7. 测试:

配置ELK

配置elasticsearch.yml

# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
#       Before you set out to tweak and tune the configuration, make sure you
#       understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
#cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
#node.name: node-1
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
#path.data: /path/to/data
#
# Path to log files:
#
#path.logs: /path/to/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# By default Elasticsearch is only accessible on localhost. Set a different
# address here to expose this node on the network:
#
cluster.name: "docker-cluster"
node.name: "node-1"
node.master: true
network.host: 0.0.0.0#xpack.license.self_generated.type: trial
#xpack.security.enabled: true
#xpack.monitoring.collection.enabled: true #
# By default Elasticsearch listens for HTTP traffic on the first free port it
# finds starting at 9200. Set a specific HTTP port here:
#
http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.seed_hosts: ["host1", "host2"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
cluster.initial_master_nodes: ["node-1"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true

启动bin目录下的elasticsearch.bat

以下是启动效果

配置logstash.conf
