windows環境部署美團Cat分佈式監控系統

一、源碼下載

CAT源碼地址: https://github.com/dianping/cat
網絡原因，下載過慢建議使用國內資源如：
馬雲源碼下載 https://gitee.com/zz20160215/cat

二、Maven配置

由於很多需要的jar包需要國外maven中央倉庫，建議配置國內maven鏡像

<mirror>
	<id>alimaven</id>
	<name>aliyun maven</name>
	<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
	<mirrorOf>central</mirrorOf>        
</mirror>

三、編譯Cat源碼

1、下載源碼後，在源碼目錄執行maven命令 mvn clean install -Dmaven.test.skip=true(跳過測試代碼)
2、編譯成功後，會在Cat統計目錄下生產Data文件夾。此時需要對此文件夾進行開放讀寫權限操作。

3、在cat目錄下執行 mvn cat:install
此命令執行過程中需要你輸入mysql數據庫地址、賬戶、密碼，確保賬戶有創建庫、表的權限
注意：此過程中出現此錯誤問題

 java.sql.SQLException: java.lang.ClassCastException: java.math.BigInteger cannot be cast to java.lang.Long

解決辦法：將cat文件中pom.xml中mysql-connector-java版本改爲如下

<dependency>
   <groupId>mysql</groupId>
   <artifactId>mysql-connector-java</artifactId>
   <version>5.1.46</version>
</dependency>

mvn cat:install執行成功後，即可在數據庫看到cat數據庫

4、修改data目錄下配置文件
client.xml 客戶端配置文件

<?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="127.0.0.1" port="2280" http-port="8080" />
		<!-- If under production environment, put actual server address as list. -->
		<!-- 
			<server ip="192.168.7.71" port="2280" /> 
			<server ip="192.168.7.72" port="2280" /> 
		-->
	</servers>
</config>

server.xml服務端配置文件

<?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>127.0.0.1:8080</remote-servers>		
	</console>
		
</config>

<!-- Configuration for production environment -->
<!-- Note: -->
<!-- 1. Set local-mode false to activate remote mode. -->
<!-- 2. If machine is job-machine, set job-machine true, you just need config only one machine. Job is offline for report aggreation, statistics report.-->
<!-- 3. If machine is alert-machine, set alert-machine true, you just need config only one machine. -->
<!-- 4. Cat can run without hdfs, you just config hdfs-machine false. If you have hdfs, you can config hdfs info for saving the logview info.  -->
<!-- 5. If you don't need hdfs, the logview will be stored in local disk. You can config max local-logivew-storage-time for cleaning up old logview, the unit is day. -->
<!-- 6. Please set hadoop environment accordingly. -->
<!-- 7. Please set ldap info for login the system. -->
<!-- 8. Please config remote-server if you have many cat servers. -->
<!-- 
<config local-mode="false" hdfs-machine="false" job-machine="false" 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">
		<hdfs id="logview" max-size="128M" server-uri="hdfs://10.1.77.86/user/cat" base-dir="logview"/>
		<hdfs id="dump" max-size="128M" server-uri="hdfs://10.1.77.86/user/cat" base-dir="dump"/>
		<hdfs id="remote" max-size="128M" server-uri="hdfs://10.1.77.86/user/cat" base-dir="remote"/>
	</storage>

	<console default-domain="Cat" show-cat-domain="true">
		<remote-servers>192.168.0.1:2281,192.168.0.2:2281</remote-servers>		
	</console>
	
	<ldap ldapUrl="ldap://192.168.50.11:389/DC=dianpingoa,DC=com"/>
</config>

-->

四、部署Cat服務

在tomcat下部署cat服務步驟：
1、在E:\cat\cat-home\target目錄下找到 cat-alpha-1.4.0.war文件

2、複製此文件到tomcat下的webapps下，修改名稱 cat.war
3、啓動tomcat,訪問127.0.0.1\cat

最後

至此美團分佈式監控系統cat服務端就部署完成，剩下就是客戶端進行相關配置來監控，這樣服務端就可以監控客戶端的各項指標。具體配置在cat目錄下 /框架埋點方案集成
