mycat-2、window和linux安装配置mycat进行分表分库

1、下载mycatdl.mycat.io/1.6-RELEASE…

2、修改部分配置文件

server.xml，rule.xml，schema.xml

server.xml

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

    <tableRule name="sharding-by-date">

</mycat:rule>

然后在本地数据库中建立4张表

CREATE TABLE `fishcartableinfo_2018_11_6` (
  `ID` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `BrandUserID` int(10) unsigned NOT NULL,
  `AreaGlobel` varchar(1024) NOT NULL,
  `ResultIndex` tinyint(3) unsigned NOT NULL,
  `BrandGlobel` bigint(20) unsigned NOT NULL,
  `SystemGlobel` bigint(20) unsigned NOT NULL,
  `RoleSum` int(10) unsigned NOT NULL,
  `LogTime` datetime NOT NULL,
  PRIMARY KEY (`ID`)
) ENGINE=InnoDB AUTO_INCREMENT=955 DEFAULT CHARSET=utf8;
CREATE TABLE `fishcartableinfo_2018_11_7` (
  `ID` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `BrandUserID` int(10) unsigned NOT NULL,
  `AreaGlobel` varchar(1024) NOT NULL,
  `ResultIndex` tinyint(3) unsigned NOT NULL,
  `BrandGlobel` bigint(20) unsigned NOT NULL,
  `SystemGlobel` bigint(20) unsigned NOT NULL,
  `RoleSum` int(10) unsigned NOT NULL,
  `LogTime` datetime NOT NULL,
  PRIMARY KEY (`ID`)
) ENGINE=InnoDB AUTO_INCREMENT=955 DEFAULT CHARSET=utf8;
CREATE TABLE `fishcartableinfo_2018_11_8` (
  `ID` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `BrandUserID` int(10) unsigned NOT NULL,
  `AreaGlobel` varchar(1024) NOT NULL,
  `ResultIndex` tinyint(3) unsigned NOT NULL,
  `BrandGlobel` bigint(20) unsigned NOT NULL,
  `SystemGlobel` bigint(20) unsigned NOT NULL,
  `RoleSum` int(10) unsigned NOT NULL,
  `LogTime` datetime NOT NULL,
  PRIMARY KEY (`ID`)
) ENGINE=InnoDB AUTO_INCREMENT=955 DEFAULT CHARSET=utf8;
CREATE TABLE `fishcartableinfo_2018_11_9` (
  `ID` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `BrandUserID` int(10) unsigned NOT NULL,
  `AreaGlobel` varchar(1024) NOT NULL,
  `ResultIndex` tinyint(3) unsigned NOT NULL,
  `BrandGlobel` bigint(20) unsigned NOT NULL,
  `SystemGlobel` bigint(20) unsigned NOT NULL,
  `RoleSum` int(10) unsigned NOT NULL,
  `LogTime` datetime NOT NULL,
  PRIMARY KEY (`ID`)
) ENGINE=InnoDB AUTO_INCREMENT=955 DEFAULT CHARSET=utf8;

然后插入一些数据

最后将mycat启动，

在bin目录下，按住shift 右键，选择在当前目录打开命令行 执行命令startup_nowrap.bat

出现successfull即为成功

这个时候可以使用Navicat工具来链接

localhost

8806

root

root

如果连接未成功：替换lib目录下的Mycat-server-1.6-RELEASE.jar

为Mycat-server-1.6.5-DEV.jar

链接成功之后，本地的mysql的四张表的数据会同步到这一张表里面，这样就可以像mysql中查询数据的方式查询多表

linux中安装和配置

1、yum安装mycat

2、开放端口8066

3、修改相关的配置文件如上所示

4、linux中的启动方式

进入安装的bin目录下

执行 ./mycat console 命令

如果出现successfull即为成功，然后再Navicat中测试连接即可

注意：linux中启动需要配置的有jdk mysql环境，否则启动不成功

mycat1.6中貌似没有按日期分片的规则，需要重构代码，

源码如下mycat1.6jar包反编译的源码-Java代码类资源-CSDN下载
