日志收集ELK与分布式系统监控CAT
Spring Boot项目集成方法
一. pom.xml引入starter依赖
<dependency>
<groupId>com.louis</groupId>
<artifactId>ylog-spring-boot-starter</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
二. bootstrap.yml配置文件开启日志
ylog:
enable-y-log: ${YLog_Enable:true}
app-name: ${spring.application.name}
env: ${spring.profiles.active}
cat:
enable-cat: ${YLog_Enable_Cat:true}
http-port: ${YLog_Cat_HttpPort:8081}
port: ${YLog_Cat_Port:2280}
cat-servers: ${YLog_Cat_Servers:192.168.102.212}
enable-spring-bean-aop: true
elk:
enable-elk: ${YLog_Enable_Elk:true}
logstash-host: ${YLog_Enable_elk:192.168.102.130:30309}
附录:服务安装
一. ELK安装
1. ElasticSearch安装
-
下载所需版本压缩包并解压
-
修改/config/elasticsearch.yml
network.host=127.0.0.1 network.port=9200
-
启动/bin/elasticsearch.bat
-
浏览器访问http://localhost:9200/,正常返回ES服务器json格式信息,即为安装成功
2. Logstash安装
-
下载所需版本压缩包并解压
-
修改/config/logstash.yml
xpack.monitoring.elasticsearch.hosts: ["http://localhost:9200"]
-
新建/config/log4j_to_es.conf文件,文件内容如下:
input { tcp { port => 4560 codec => json_lines } } output { elasticsearch { hosts => "127.0.0.1:9200" index => "applog" } stdout { codec => rubydebug} }
-
新建/bin/run_default.bat文件,文件内容如下:
D:ELKlogstash-7.4.0inlogstash.bat -f D:ELKlogstash-7.4.0inlog4j_to_es.conf pause
-
启动/bin/run_default.bat
-
查看控制台输出,没有ERROR。浏览器访问http://localhost:9600/, 正常返回服务器json格式信息,即为安装成功
-
3. Kibana安装
-
下载所需版本压缩包并解压
-
修改/config/kibana.yml
elasticsearch.hosts: ["http://localhost:9200"] elasticsearch.requestTimeout: 90000
-
运行/bin/kibana.bat
-
访问http://localhost:5601 正常展示kibana页面,即为安装成功
官方文档: gitbook
二. CAT安装
-
下载官方开源源码: https://github.com/dianping/cat.git
-
切换到2.0.0版本(一部分cat插件在3.0.0的版本中移除了,需要先在2.0.0的版本上安装到本地maven库):
git checkout v2.0.0
-
执行mvn命令安装插件
mvn clean install -Dmaven.test.skip=true
-
切换到3.0.0版本
git checkout v3.0.0
-
新建mysql数据库cat, 执行3.0.0分支下的/script/CatApplication.sql脚本完成初始化
-
新增配置文件client.xml到tomcat安装盘,如文件目录:C:dataappdatascatclient.xml,配置内容:
<?xml version="1.0" encoding="utf-8"?> <config mode="client" xmlns:xsi="http://www.w3.org/2001/XMLSchema" xsi:noNamespaceSchemaLocation="config.xsd"> <servers> <!-- Local mode for development --> <server ip="10.0.75.1" port="2280" http-port="8080" /> <!-- If under production environment, put actual server address as list. --> <!-- <server ip="192.168.7.71" port="2280" /> --> </servers> </config>
本地调试时ip为本机内网地址,写127.0.0.1可能导致服务启动失败
-
新增配置文件server.xml到tomcat安装盘,如文件目录C:dataappdatascatserver.xml,配置内容:
<?xml version="1.0" encoding="utf-8"?> <!-- Configuration for development environment--> <config local-mode="false" hdfs-machine="false" job-machine="true" alert-machine="false"> <storage local-base-dir="/data/appdatas/cat/bucket/" max-hdfs-storage-time="15" local-report-storage-time="7" local-logivew-storage-time="7"> </storage> <console default-domain="Cat" show-cat-domain="true"> <remote-servers>10.0.75.1:8080</remote-servers> </console> </config>
本地调试时ip为本机内网地址,写127.0.0.1可能导致服务启动失败
-
新增配置文件datasources.xml到tomcat安装盘,如文件目录C:dataappdatascatdatasources.xml,配置内容:
<?xml version="1.0" encoding="utf-8"?> <data-sources> <data-source id="cat"> <maximum-pool-size>3</maximum-pool-size> <connection-timeout>1s</connection-timeout> <idle-timeout>10m</idle-timeout> <statement-cache-size>1000</statement-cache-size> <properties> <driver>com.mysql.jdbc.Driver</driver> <url><![CDATA[jdbc:mysql://127.0.0.1:3306/cat]]></url> <user>root</user> <password>123456</password> <connectionProperties><![CDATA[useUnicode=true&autoReconnect=true]]></connectionProperties> </properties> </data-source> <data-source id="app"> <maximum-pool-size>3</maximum-pool-size> <connection-timeout>1s</connection-timeout> <idle-timeout>10m</idle-timeout> <statement-cache-size>1000</statement-cache-size> <properties> <driver>com.mysql.jdbc.Driver</driver> <url><![CDATA[jdbc:mysql://127.0.0.1:3306/cat]]></url> <user>root</user> <password>123456</password> <connectionProperties><![CDATA[useUnicode=true&autoReconnect=true]]></connectionProperties> </properties> </data-source> </data-sources>
-
-
执行mvn命令打包源码
mvn clean install -Dmaven.test.skip=true
-
拷贝/cat-home/target/cat-home-3.0.0.jar到tomcat的安装目录下,并重命名为car.jar: /webapps/cat.jar
-
启动tomcat
-
访问http://localhost:8080/cat, 正常展示cat主页,即为安装成功
