查看binlog，并分析binlog
mysql> show binary logs;
+-------------------+-----------+
| Log_name | File_size |

| master-bin.000002 | 4061 |

5 rows in set (0.01 sec)
使用mysqlbinlog查看binlog的内容
mysqlbinlog --no-defaults --database=lzldb --start-datetime='2020-08-07 00:00:00' --stop-datetime='2020-08-07 18:00:00' master-bin*> binloglzl1.log
