从零开始mycat实验环境搭建

版本说明

本机：

jdk 8

使用IntelliJ IDEA调试MyCAT 1.6 release

主机一：droplet CentOS 7.5 x86_64

MyCAT 1.6 release

OpenJDK 1.8

MySQL-Server 5.7

主机二：bandwagon CentOS 6.8 i686

MySQL-Client 5.6

实验过程

0. 调整时区
timedatectl set-local-rtc 1
timedatectl set-timezone Asia/Shanghai

1. MySQL 5.7 安装

为加快速度，使用二进制安装

规划了三个实例

2.3 安装5.6-client

有win版本navicat的同学可以跳过这一步。

wget https://dev.mysql.com/get/Downloads/MySQL-5.6/MySQL-5.6.42-1.el6.x86_64.rpm-bundle.tar

对于mac：brew install mysql@5.6，安装5.6client是因为navicat查询的时候喜欢多发送查询命令，干扰到调试进程。

3. 验证
3.1 全局表中插入数据要求表带_mycat_op_time字段

insert into t_artist set id='10000', artist_name='Sergei Rachmaninoff', birth_date='1873-04-01';
insert into t_artist set id='10001', artist_name='Franz Schubert', birth_date='1797-01-31';

3.2 分库表中插入数据

use db_music;
desc t_album;
##ERROR 1064 (HY000): partition table, insert must provide ColumnList
##insert into t_album values('0','Trout','2012-2-3',10001);

##ERROR 1064 (HY000): bad insert sql (sharding column:ID not provided,INSERT INTO t_album (name, release, artist)
##insert into t_album(name,release,artist) VALUES('Trout','2012-02-03','10001');

insert into t_album(id,name) VALUES(0,'Trout');

##ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'release,artist) VALUES(0,'Trout','2012-02-03','10001')' at line 1

insert into t_album(id,name,release,artist) VALUES(0,'Trout','2012-02-03','10001');
