CAT服务端安装

我的本地开发环境

• 操作系统： macOS Catalina 10.15.6
• IDE： Intelij IDEA
• JDK版本：1.8
• Mysql： 5.7.21
• Maven： 3.6.3
• Server version: Apache Tomcat/8.5.70

一、Cat 源代码下载

下载地址：https://github.com/dianping/cat

• cat源码：下载 master 分支代码
• cat依赖包：下载 mvn-repo 分支代码

二、在本地打 cat 的 war 包

在cat工程执行编译命令

# zhangquan @ MacBook-Pro in ~/docker-php-dev/www/github/cat on git:master x [20:29:15] C:1
$ mvn clean compile

• 报错1：Could not find artifact org.unidal.framework:foundation-service:jar:2.5.0

[ERROR] Failed to execute goal on project cat-core: Could not resolve dependencies for project com.dianping.cat:cat-core:jar:3.0.0: The following artifacts could not be resolved: org.unidal.framework:foundation-ser
vice:jar:2.5.0, org.unidal.framework:web-framework:jar:2.4.0, org.unidal.framework:dal-jdbc:jar:2.4.0: Could not find artifact org.unidal.framework:foundation-service:jar:2.5.0 in alimaven (http://maven.aliyun.com/
nexus/content/groups/public) -> [Help 1]

解决：将下载的mvn-repo分支解压，放入到本地的.m2仓库中；

本地 mvn-repo 分支解压，解压出org目录，并将org目录拷贝到本地的.m2仓库中

$ ll ~/.m2/repository/org/unidal 
drwxrwxr-x@  3 zhangquan  180847186    96B 11 14  2017 eunit
drwxrwxr-x@ 11 zhangquan  180847186   352B 11 14  2017 framework
drwxrwxr-x@  4 zhangquan  180847186   128B 11 23 20:31 maven
drwxrwxr-x@  9 zhangquan  180847186   288B 11 14  2017 webres

再执行编译命令：

• 报错2：Could not find artifact org.codehaus.plexus:plexus-container-default:jar:3.1.0

[ERROR] Failed to execute goal org.unidal.maven.plugins:codegen-maven-plugin:2.5.8:dal-model (generate data model) on project cat-client: Execution generate data model of goal org.unidal.maven.plugins:codegen-maven-plugin:2.5.8:dal-model failed: Plugin org.unidal.maven.plugins:codegen-maven-plugin:2.5.8 or one of its dependencies could not be resolved: Could not find artifact org.codehaus.plexus:plexus-container-default:jar:3.1.0 in unidal (http://unidal.org/nexus/content/repositories/releases/) -> [Help 1]

解决：在.m2仓库找到org.unidal.maven.plugins:codegen-maven-plugin:2.5.8版本的pom文件codegen-maven-plugin-2.5.8.pom用idea打开，点击父引用的default，跳转到default-2.5.8.pom文件中，将文件中foundation-service.version从3.1.0版本修改为4.0.0版本；

再执行编译命令：编译即可成功

在cat根目录执行install命令

# zhangquan @ MacBook-Pro in ~/docker-php-dev/www/github/cat on git:master x [20:49:13] C:130
$ mvn clean install -DskipTests

报错：Failure to find org.unidal.framework:test-framework:jar:2.4.0

[ERROR] Failed to execute goal on project cat-client: Could not resolve dependencies for project com.dianping.cat:cat-client:jar:3.0.0: Failure to find org.unidal.framework:test-framework:jar:2.4.0 in http://unidal.org/nexus/content/repositories/releases/ was cached in the local repository, resolution will not be reattempted until the update interval of unidal has elapsed or updates are forced -> [Help 1]

解决：修改cat根目录的pom.xml文件中test-framework的版本，改为2.5.0

再执行install命令：安装成功

install成功后，将cat-home-3.0.0.war修改为cat.war

查看每个module具体生效的pom信息

在cat根目录执行命令：打开cat.txt，即可看到cat-home定义的version

mvn help:effective-pom > cat.txt

三、服务端安装和配置

安装CAT的数据库

• 创建数据库，数据库名cat，数据库编码使用utf8mb4，否则可能造成中文乱码等问题；

CREATE DATABASE `cat` DEFAULT CHARACTER SET utf8mb4 ;

• 将 cat工程中，script目录中的 sql 拷贝到cat数据库运行

sql拷贝到cat数据库运行，初始化数据表；

由于MySQL的系统参数max_allowed_packet默认配置较小，可能会限制server接受的数据包大小，有时候大的插入和更新会被max_allowed_packet 参数限制掉，导致失败，所以要修改max_allowed_packet的值，修改后需要重启mysql；

Cat配置文件

创建以下两个目录：

• /data/appdatas/cat
• /data/applogs/cat

在 /data/appdatas/cat 目录中，添加 client.xml，datasources.xml 配置文件

client.xml配置

<?xml version="1.0" encoding="utf-8"?>
<config mode="client">
    <servers>
          <!-- 服务端地址, 端口固定-->
		  <!-- 如果有多个Server, 就继续增加相应的节点配置 -->
		  <!-- 这是告诉客户端应该去链接哪个服务端，从哪个服务端里获取配置信息 ，相关源码也在 DefaultClientConfigManager中 -->
		  <!--将172.16.48.114修改为部署CAT的内网IP,请不要写127.0.0.1和外网IP -->
		 <server ip="172.16.48.114" port="2280" http-port="8080" />
    </servers>
</config>

datasources.xml配置文件

<?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://www.myvbox.com:3306/cat]]></url>  <!-- 请替换为真实数据库URL及Port  -->
            <user>root</user>  <!-- 请替换为真实数据库用户名  -->
            <password>123456</password>  <!-- 请替换为真实数据库密码  -->
            <connectionProperties><![CDATA[useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&socketTimeout=120000]]></connectionProperties>
        </properties>
    </data-source>
</data-sources>

tomcat启动cat项目

将cat.war拷贝到tomcat的webapps目录，再启动tomcat；

运行命令启动 tomcat

启动成功后，访问：http://localhost:8080/cat/r

按照实际需要，修改服务端配置和客户端路由

使用admin/admin登录

进入【服务端配置】页面修改IP地址：
