Otter双A同步搭建入门教程

烂漫一生 提交于 2020-03-09 20:10:21

1.准备阶段

1.1 环境

虚拟机A :192.168.0.130

虚拟机B :192.168.0.131

系统:Ubuntu 16.04 LTS

JRE:OpenJDK 1.8.0_151(A、B都要安装)

DB:MySQL 5.7.20(A、B都要安装)

ZooKeeper:3.4.11(只装A机)

Otter Manager:4.2.14 (只装A机)(4.2.15启动Node时感觉有Bug,没有使用)

Otter Node:4.2.14(A、B都要安装)

1.2 安装环境

1.2.1 JRE安装

sudo apt-get install default-jre

 

1.2.2 MySQL安装

sudo apt-get install mysql-server

sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf

character-set-server=utf8
log-bin=mysql-bin   
binlog-format=ROW   
server-id=1 #A,B需要设置成不一样的id
#bind-address=127.0.0.1 #注释该行

service mysql restart 

进入mysql,设置单独账号密码

grant all on *.* to 'root'@'%' identified by 'password';

 

1.2.3 ZooKeeper安装

安装包地址 http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.11/zookeeper-3.4.11.tar.gz

解压可见conf文件夹下有一个zoo_sample.cfg的文件,重命名为zoo.cfg并修改以下配置

dataDir=../datas
dataLogDir=../logs

 

1.2.4 Otter Manager安装

安装包地址 https://github.com/alibaba/otter/releases 请自己选择版本

解压可见conf文件夹下otter.properties文件,修改以下配置

#以下配置为最基本需要改的配置,其他配置可根据实际要用的功能进行修改
otter.domainName = 192.168.0.130 #一定要改,不要用127.0.0.1
otter.port = 9000 #manager 站点端口号
otter.database.driver.url = jdbc:mysql://192.168.0.130:3306/otter
otter.database.driver.username = root
otter.database.driver.password = password
otter.zookeeper.cluster.default = 192.168.0.130:2181

 

1.2.5 Otter Node 安装

安装包地址 https://github.com/alibaba/otter/releases 请自己选择版本

解压可见conf文件夹下otter.properties文件,修改以下配置

#以下配置为最基本需要改的配置,其他配置可根据实际要用的功能进行修改
otter.nodeHome = ../
otter.manager.address = 192.168.0.130:1099 

conf文件夹下创建一个新的配置文件,命名为nid,写入node id,A机为1,B机为2。该id后面会介绍。

1  

 

2.启动

2.1 启动ZooKeeper

进入ZooKeeper目录下的bin文件夹,执行以下命令(不要使用sh,一定要用bash)

bash zkServer.sh start

 

2.2 启动Otter Manager

在A机中执行以下数据库语句,创建Otter库

在A,B机中都要执行以下数据库语句,创建retl库(若只是单向同步,则不需要执行该语句。该语句用作双A同步时的算法)

/*
供 otter 使用, otter 需要对 retl.* 的读写权限,以及对业务表的读写权限
1. 创建database retl
*/
CREATE DATABASE retl;

/* 2. 用户授权 给同步用户授权 */
CREATE USER retl@'%' IDENTIFIED BY 'retl';
GRANT USAGE ON *.* TO `retl`@'%';
GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO `retl`@'%';
GRANT SELECT, INSERT, UPDATE, DELETE, EXECUTE ON `retl`.* TO `retl`@'%';
/* 业务表授权,这里可以限定只授权同步业务的表 */
GRANT SELECT, INSERT, UPDATE, DELETE ON *.* TO `retl`@'%';  

/* 3. 创建系统表 */
USE retl;
DROP TABLE IF EXISTS retl.retl_buffer;
DROP TABLE IF EXISTS retl.retl_mark;
DROP TABLE IF EXISTS retl.xdual;

CREATE TABLE retl_buffer
(	
	ID BIGINT(20) AUTO_INCREMENT,
	TABLE_ID INT(11) NOT NULL,
	FULL_NAME varchar(512),
	TYPE CHAR(1) NOT NULL,
	PK_DATA VARCHAR(256) NOT NULL,
	GMT_CREATE TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
	GMT_MODIFIED TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
	CONSTRAINT RETL_BUFFER_ID PRIMARY KEY (ID) 
)  ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE retl_mark
(	
	ID BIGINT AUTO_INCREMENT,
	CHANNEL_ID INT(11),
	CHANNEL_INFO varchar(128),
	CONSTRAINT RETL_MARK_ID PRIMARY KEY (ID) 
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

CREATE TABLE xdual (
  ID BIGINT(20) NOT NULL AUTO_INCREMENT,
  X timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (ID)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

/* 4. 插入初始化数据 */
INSERT INTO retl.xdual(id, x) VALUES (1,now()) ON DUPLICATE KEY UPDATE x = now();

进入Otter Manager 下的bin目录

bash startup.sh

这时等待数秒,Otter Manager站点已启动,可以访问http://192.168.0.130:9000配置Otter Node 的信息了。

 

2.3 启动Otter Node

如果你未在Otter Manager站点配置Otter Node的信息,则请暂时跳过该节,直接查看下面配置章节,配置完成后再回来该节启动Otter Node

进入Otter Node下的bin目录

bash startup.sh

    

3.配置

进入Otter Manager站点后,使用账号:admin,密码:admin(默认),获得超级管理员权限。

3.1 ZooKeeper配置

机器管理  -->  ZooKeeper管理 ,添加,保存,如下图

 

 3.2 Node配置

机器管理  -->  Node管理 ,添加,保存(2次,A机一个Node,B机一个Node),如下图(名称和IP需要根据不同机器修改,这里只列出A机图片)

最后可在Node管理列表中看见,其中序号即我们上面安装过程中写入的nid文件的id号,配置好之后,即可启动Otter Node

启动后可见配置列表

3.3 数据源配置

配置管理  -->  数据源配置,配置A机、B机两个MySQL 数据源

配置完成后可见配置列表

3.4 数据表配置

配置管理  -->  数据表配置,配置A机、B机两个MySQL 数据源所需要同步的数据表(自己的数据库,我这里新建test库),其中table name配置如果想同步所有表则配置为.*,否则则配置对应表名即可

配置完成后可见配置列表

 

3.5 Canal配置

将canal看作是A、B两机的从库即可,github上解释道,canal模拟mysql slave的交互协议,伪装自己为mysql slave,向mysql master发送dump协议。

配置管理  -->  canal配置,配置A机、B机两个canal。实质上两个canal分别运行在A、B两机上的Node节点上。配置如下,其他使用默认配置。

位点信息分别在A、B两个MySQL执行以下语句获取

show master status;
select unix_timestamp(now());

配置完成后可见配置列表

 

3.6 同步任务配置

同步管理 -->  Channel管理 ,添加一个Channel

 

添加后,点击进入Pipeline管理

添加两个Pipeline,如图是其中一个方向,另外一个方向Select、Load机器相反。canal选择与Node机器选择一致方向,即要与Select机器一样。选择其中一个Pipeline作为主站点,并在高级设置中勾选支持ddl同步,另外一个主站点勾选否,支持ddl同步选择否。

 

添加后,点击进入映射关系列表,选择好同步表的方向

至此。配置完成。到Channel管理中开启同步任务,Otter将为我们自动双A同步数据啦!
