Appendix: Installation Services

A. ELK installation

1. ElasticSearch installation

Download the archive and extract the required version

Two. CAT installation

Download the official Open Source Source: https://github.com/dianping/cat.git
Switch to the 2.0.0 version (removing part of the plug-cat version 3.0.0, you need to install to the local maven repository in the 2.0.0 version):
```
git checkout v2.0.0
```
Execute mvn command to install the plug-in
```
mvn clean install -Dmaven.test.skip=true
```
Switch to version 3.0.0
```
git checkout v3.0.0
```
Create mysql database cat, script execution /script/CatApplication.sql 3.0.0 branch to complete the initialization

New configuration file client.xml to tomcat installation disk, such as file directory: C: \ data \ appdatas \ cat \ client.xml, configuration elements:

<?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>

Local debugging within the native network ip address, write 127.0.0.1 could lead to service failed to start

New server.xml configuration file to the tomcat installation disk, such as file directory C: \ data \ appdatas \ cat \ server.xml, configuration elements:

<?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>

Local debugging within the native network ip address, write 127.0.0.1 could lead to service failed to start
