canal同步mysql数据到elasticsearch7.15.0_error c.a.o.canal.adapter.launcher.loader.canalada

error c.a.o.canal.adapter.launcher.loader.canaladapterloader

1.准备

官方网址:https://github.com/alibaba/canal/wiki/QuickStart
对于自建 MySQL , 需要先开启 Binlog 写入功能,配置 binlog-format 为 ROW 模式,my.cnf 中配置如下

[mysqld]
log-bin=mysql-bin # 开启 binlog
binlog-format=ROW # 选择 ROW 模式
server_id=1 # 配置 MySQL replaction 需要定义,不要和 canal 的 slaveId 重复

注意:针对阿里云 RDS for MySQL , 默认打开了 binlog , 并且账号默认具有 binlog dump 权限 , 不需要任何权限或者 binlog 设置,可以直接跳过这一步

授权 canal 链接 MySQL 账号具有作为 MySQL slave 的权限, 如果已有账户可直接 grant

CREATE USER canal IDENTIFIED BY 'canal';  
GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'canal'@'%';
-- GRANT ALL PRIVILEGES ON *.* TO 'canal'@'%' ;
FLUSH PRIVILEGES;

# table regex
#table正则表达式默认所有
#mysql 数据解析关注的表,Perl正则表达式.
#多个正则之间以逗号(,)分隔,转义符需要双斜杠(\\) 
#常见例子:
#1.  所有表:.*   or  .*\\..*
#2.  canal schema下所有表: canal\\..*
#3.  canal下的以canal打头的表:canal\\.canal.*
#4.  canal schema下的一张表:canal.test1
#5.  多个规则组合使用:canal\\..*,mysql.test1,mysql.test2 (逗号分隔)
#注意:此过滤条件只针对row模式的数据有效(ps. mixed/statement因为不解析sql,所以无法准确提取tableName进行过滤)
canal.instance.filter.regex=.*\\..*
# table black regex
canal.instance.filter.black.regex=mysql\\.slave_.*
# table field filter(format: schema1.tableName1:field1/field2,schema2.tableName2:field1/field2)
#canal.instance.filter.field=test1.t_product:id/subject/keywords,test2.t_company:id/name/contact/ch
# table field black filter(format: schema1.tableName1:field1/field2,schema2.tableName2:field1/field2)
#canal.instance.filter.black.field=test1.t_product:subject/product_image,test2.t_company:id/name/contact/ch

# mq config
canal.mq.topic=example
# dynamic topic route by schema or table regex
#canal.mq.dynamicTopic=mytest1.user,mytest2\\..*,.*\\..*
canal.mq.partition=0
# hash partition config
#canal.mq.partitionsNum=3
#canal.mq.partitionHash=test.table:id^name,.*\\..*
#canal.mq.dynamicTopicPartitionNum=test.*:4,mycanal:6

原因:canaladapter-1.1.5版本的druid包冲突
解决1:
下载v1.1.5-alpha-2版本的
解压后,将canaladapter-1.1.5的plugin里面的client-adapter.es7x-1.1.5-jar-with-dependencies.jar替换为v1.1.5-alpha-2版本中plugin里面的client-adapter.es7x-1.1.5-SNAPSHOT-jar-with-dependencies.jar

修改数据查看日志:

tail -f logs/adapter/adapter.log

5.admin安装

解压到对应目录,执行启动脚本,这里就不多说了

sh bin/startup.sh
