- Check binlog status
-- https://github.com/alibaba/canal/wiki/AdminGuide
show variables like 'log_bin';
show variables like 'binlog_format';
- MySQL Binlog权限需要三个权限 SELECT, REPLICATION SLAVE, REPLICATION CLIENT
GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'canal'@'%' IDENTIFIED BY 'canal';
- 缺乏SELECT权限时，报错为
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException:
Access denied for user 'canal'@'%' to database 'binlog'
- 缺乏REPLICATION SLAVE权限时，报错为
java.io.IOException:
Error When doing Register slave:ErrorPacket [errorNumber=1045, fieldCount=-1, message=Access denied for user 'canal'@'%'
- 缺乏REPLICATION CLIENT权限时，报错为
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException:
Access denied; you need (at least one of) the SUPER, REPLICATION CLIENT privilege(s) for this operation
-
Binlog为什么需要这些权限：
-
Select权限代表允许从表中查看数据
Replication client权限代表允许执行show master status,show slave status,show binary logs命令
Replication slave权限代表允许slave主机通过此用户连接master以便建立主从 复制关系
