canal实时同步mysql表到es

方案说明

canal是阿里云开源的解析binlog组件，同步到ES需要deployer和adapter两部分：
deployer解析MySQL binlog，adapter将数据写入到ES

优点

开源成熟稳定
简单易用

缺点

不支持全量数据初始化

部署

logstash进行全量
/etc/hosts配置es7.test.com域名解析

deployer

wget https://github.com/alibaba/canal/releases/download/canal-1.1.5/canal.deployer-1.1.5.tar.gz
tar zxf canal.deployer-1.1.5.tar.gz -C deployer
cd deployer

adapter
