### 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：
|
|
|
|
|
|
```text
|
|
|
|
|
|
[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
|
|
|
|
|
|
```sql
|
|
|
|
|
|
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
|
|
|
|
|
|
```sql
|
|
|
|
|
|
set global gtid_mode = OFF_PERMISSIVE;
|
|
|
|
|
|
set global gtid_mode = ON_PERMISSIVE;
|
|
|
|
|
|
set global enforce_gtid_consistency = ON;
|
|
|
|
|
|
set global gtid_mode=ON;
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
