Mycat学习手册--05Mycat安装启动

6.Mycat安装启动

Mycat使用Java编写,所以需要优先安装jdk,此处略过,本文使用版本如下:

  • jdk 1.8
  • MyCat Mycat-server-1.6-RELEASE-20161028204710-linux

如果未安装jdk,请提前下载:

https://www.oracle.com/cn/java/technologies/javase/javase8-archive-downloads.html

6.1下载解压

官网下载地址:http://dl.mycat.org.cn/

官网中选择对应平台及版本的压缩包:

6.2 文件复制

将解压后的目录copy到 /usr/local目录中

[root@mycat opt]# cp -r mycat/ /usr/local/

[root@mycat opt]# ls /usr/local/
bin  etc  games  include  lib  lib64  libexec  mycat  sbin  share  src
[root@mycat opt]# 

查看mycat目录及mycat的配置文件目录

[root@mycat opt]# cd /usr/local/mycat/
[root@mycat mycat]# ls

Mycat学习手册--05Mycat安装启动_第2张图片其中主要的几个配置文件如下:

  • server.xml:是Mycat服务器参数调整和用户授权的配置文件。

  • schema.xml:是逻辑库定义和表以及分片定义的配置文件。

  • rule.xml: 是分片规则的配置文件,分片规则的具体一些参数信息单独存放为文件,也在这个目录下,配置文件修改需要重启MyCAT。

  • log4j.xml: 日志存放在logs/log中,每天一个文件,日志的配置是在conf/log4j.xml中,根据自己的需要可以调整输出级别为debug

    • debug级别下,会输出更多的信息,方便排查问题。
  • autopartition-long.txt,partition-hash-int.txt,sequence_conf.properties, sequence_db_conf.properties 分片相关的id分片规则配置文件

  • lib MyCAT自身的jar包或依赖的jar包的存放目录。

  • logs MyCAT日志的存放目录。日志存放在logs/log中,每天一个文件

6.3 配置

需要安装jdk,修改jdk环境,即编辑 /usr/local/mycat/conf/wrapper.conf

 vi /usr/local/mycat/conf/wrapper.conf 

配合java命令绝对路径

wrapper.java.command=/opt/jdk1.8.0_291/bin/java

配置mycat 和mysql数据库连接等信息

1.修改server.xml

修改user用户信息
Mycat学习手册--05Mycat安装启动_第3张图片

完整的配置文件如下:




<mycat:server xmlns:mycat="http://io.mycat/">
	<system>
	<property name="useSqlStat">0property>  
	<property name="useGlobleTableCheck">0property>  

		<property name="sequnceHandlerType">2property>
       
         
	
	
		
		<property name="processorBufferPoolType">0property>
		
		
		
		
		
		
		
		
		<property name="handleDistributedTransactions">0property>
		
			
		<property name="useOffHeapForMerge">1property>

		
		<property name="memoryPageSize">1mproperty>

		
		<property name="spillsFileBufferSize">1kproperty>

		<property name="useStreamOutput">0property>

		
		<property name="systemReserveMemorySize">384mproperty>


		
		<property name="useZKSwitch">trueproperty>


	system>
	
	
	
	
	<user name="mycat">
		<property name="password">123456property>
		<property name="schemas">TESTDBproperty>
		
		
		
	user>

	<user name="user">
		<property name="password">userproperty>
		<property name="schemas">TESTDBproperty>
		<property name="readOnly">trueproperty>
	user>

mycat:server>

2.修改schema.xml

修改dataNode、dataHost



<mycat:schema xmlns:mycat="http://io.mycat/">

	<schema name="TESTDB" checkSQLschema="false" sqlMaxLimit="100" dataNode="dn1">
	schema>

	<dataNode name="dn1" dataHost="host1" database="testdb" />


	<dataHost name="host1" maxCon="1000" minCon="10" balance="2"
			  writeType="0" dbType="mysql" dbDriver="native" switchType="1"  slaveThreshold="100">
		<heartbeat>select user()heartbeat>

		
		<writeHost host="hostM1" url="172.17.0.2:3306" user="root"   password="123456">
			
			<readHost host="hostS1" url="172.17.0.3:3306" user="root" password="123456" />
		writeHost>
	dataHost>


mycat:schema>


6.4 启动

到mycat/bin目录执行shell脚本

  • 控制台启动 ./mycat console
  • 后台启动 ./mycat start

如果启动报如下错误原因是没有配置jdk
