一、环境准备

1.mysql 需开启binlog及gtid，seatunnel-cdc会伪装成mysql从库实现数据同步

mysql 8 版本参考配置如下：

[mysqld]
# binlog
server-id = 1
log-bin = mysql-bin
expire_logs_days = 7
binlog_format = row
max_binlog_size = 100m 
# enable gtid mode
gtid_mode = on
enforce_gtid_consistency = on

执行SQL验证是否开启binlog

show variables where variable_name in ('log_bin', 'binlog_format', 'binlog_row_image', 'gtid_mode', 'enforce_gtid_consistency');

!

2.开启gtid

按顺序执行以下语句

set global gtid_mode = OFF_PERMISSIVE;  
set global gtid_mode = ON_PERMISSIVE;  
set global enforce_gtid_consistency = ON;  
set global gtid_mode=ON;

二、source配置

source {
  MySQL-CDC {
    base-url = "jdbc:mysql://172.31.51.244:3306/bjpt_v4_wlmq"
    username = "manager"
    password = "manager2!@#"
  	database-names = ["bjpt_v4_wlmq"]
    table-names = ["bjpt_v4_wlmq.ryhcs_t_bqgl"]
    startup.mode = "initial"
  	schema-changes.enabled = true
  	server-id = "6500-7500"
  	table-names-config = [
      {
        table = "bjpt_v4_wlmq.ryhcs_t_bqgl"
        primaryKeys = ["ID"]
      }
    ]
  }
}
