问题如上：官网介绍

问题分析：

问题解决：

1、在canal.properties里面配置tsdb的mysql数据库，具体配置如下：

canal.instance.tsdb.enable = true
canal.instance.tsdb.dir = ${canal.file.data.dir:../conf}/${canal.instance.destination:}
#canal.instance.tsdb.url = jdbc:h2:${canal.instance.tsdb.dir}/h2;CACHE_SIZE=1000;MODE=MYSQL;
canal.instance.tsdb.url=jdbc:mysql://hadoop:3306/canal_tsdb
canal.instance.tsdb.dbUsername = root
canal.instance.tsdb.dbPassword = root

#canal.instance.tsdb.spring.xml = classpath:spring/tsdb/h2-tsdb.xml
canal.instance.tsdb.spring.xml = classpath:spring/tsdb/mysql-tsdb.xml

2、在数据库里面创建canal_tsdb数据库，数据库的用户需要有创建表的权限。

create database canal_tsdb;
