开源软件介绍：

mbinlogmq 一个基于MySQL binlog协议的数据同步中间件

什么是mbinlogmq?

mbinlogmq 是一个使用C语言开发的基于 MySQL binlog 协议的一个中间件，通过模拟Slave 来实时获取 MySQL binlog日志，并将数据变更信息以及 DB 语句发送到 RabbitMQ，中间通过监听机制与校验机制来确保不宕机的情况下的100%抵达 RMQ

设计架构

安装&编译

mbinlog依赖于一些第三方库：

请先安装依赖软件： cURL 、mysql、rabbitmq，安装完成后记住其安装的路径，进入下面的步骤

下载mbinlogmq源码

git clone https://gitee.com/josinli/mbinlogmq.git

修改 CMakeLists.txt，将如下的几行变为您上面安装的路径：

set(MYSQL_INCLUDE     /usr/local/mysql/include)      # 您系统的MySQL头文件路径set(MYSQL_LIBRARY_DIR /usr/local/mysql/lib)          # 您系统的MySQL库文件路径set(CURL_DIR          /usr/local/Cellar/curl/7.58.0) # 您系统的curl安装路径

执行编译安装命令

mkdir buildcd buildcmake .. && make && sudo make install

修改 /etc/mbinlogmq/binlog.xml 您的配置信息

<?xml version="1.0" encoding="UTF-8" author="Josin" date="2019-07-22"?><!--本配置文件安装位置：/etc/mbinlogmq/binlog.xml--><!--连接主库进行salve复制的信息--><!--请不要增加节点信息，系统会校验--><system for="slave">    <mode>rabbitmq</mode> <!-- 目前仅支持rabbitmq -->    <host>127.0.0.1</host>    <user>root</user>    <password>3333</password>    <port>3306</port>    <server_id>6</server_id>    <daemon>1</daemon></system><!--用户需要配置好下方的rabbitmq的配置选项--><rabbitmq>    <host>127.0.0.1</host>    <user>guest</user>    <password>guest</password>    <port>15672</port>    <delivery_mode>1</delivery_mode>    <name>amq.default</name>    <payload>Invalid</payload>    <routing_key>fanout</routing_key>    <vhost>/</vhost></rabbitmq>

启动您的 minblogmq

mbinlogmq -k start

此时进入 MySQL 操作，同时登录 RabbitMQ 查看消息是否成功抵达，目前的版本存在一些或多或少的问题，切勿生产环境使用。

mbinlogmq会针对不同的binlog日志生成四种类型的消息，消息类型如下

消息全部为 JSON 格式
格式如下

1、UPDATE 语句，etype等于 1，包含一个pre对象和 new对象，分别对应修改之前的数据和新的数据

{    "etype": 1,    "data" : {        "pre": {            "id":1,            "ad":2        },        "new": {            "id":1,            "ad":3        }    }}

2、INSERT 消息， etype 等于 2

{    "etype": 2,    "data" : {        "id":1,        "ad":3    }}

3、DELETE 消息， etype 等于 3

{    "etype": 3,    "data" : {        "id":1,        "ad":3    }}

4、SQL 语句 消息， etype 等于 4

{    "etype": 4,    "data": "ALTER TABLE `books`.`test_at` MODIFY COLUMN `cc` datetime(0) NULL DEFAULT NULL AFTER `bb`"}

示例消息如下：

 [x] Received {"etype":4,"data":"ALTER TABLE `books`.`test_at` \nMODIFY COLUMN `bb` date NULL DEFAULT NULL AFTER `aa`"} [x] Received {"etype":4,"data":"ALTER TABLE `books`.`test_at` \nMODIFY COLUMN `bb` date NOT NULL AFTER `aa`"} [x] Received {"etype":4,"data":"BEGIN"} [x] Received {"etype":1,"data":{"pre":{"id":1,"book_name":"傲世丹神1","book_cover":"http://img.c0m.io/quanben.io/upload/thumbnail/book_0_999/book_1.jpg","add_time":"2019-7-23 14:28:43","author_name":"寂小贼111","introduction":"废柴少年得无上传承,获逆天神脉,学绝世神功,掌握超绝丹术,这使他...","test_date":"2019-7-29"},"new":{"id":1,"book_name":"傲世丹神1","book_cover":"http://img.c0m.io/quanben.io/upload/thumbnail/book_0_999/book_1.jpg","add_time":"2019-7-23 21:47:36","author_name":"寂小贼","introduction":"废柴少年得无上传承,获逆天神脉,学绝世神功,掌握超绝丹术,这使他...","test_date":"2019-7-29"}}} [x] Received {"etype":4,"data":"COMMIT"} [x] Received {"etype":4,"data":"BEGIN"} [x] Received {"etype":1,"data":{"pre":{"id":1,"book_name":"傲世丹神1","book_cover":"http://img.c0m.io/quanben.io/upload/thumbnail/book_0_999/book_1.jpg","add_time":"2019-7-23 21:47:36","author_name":"寂小贼","introduction":"废柴少年得无上传承,获逆天神脉,学绝世神功,掌握超绝丹术,这使他...","test_date":"2019-7-29"},"new":{"id":1,"book_name":"傲世丹神","book_cover":"http://img.c0m.io/quanben.io/upload/thumbnail/book_0_999/book_1.jpg","add_time":"2019-7-23 21:47:54","author_name":"寂小贼","introduction":"废柴少年得无上传承,获逆天神脉,学绝世神功,掌握超绝丹术,这使他...","test_date":"2019-7-29"}}} [x] Received {"etype":4,"data":"COMMIT"}
