1. Make sure the database has log_bin enabled
show variables like 'log_bin';
+-------------+-----+
|Variable_name|Value|
+-------------+-----+
|log_bin |ON |
+-------------+-----+
The my.cnf configuration file adds configuration to enable:
log_bin = mysql-bin
binlog_format = mixed
expire_logs_days = 7
2. View the latest binlog file
mysql> show master status;
+-------------+---------+------------+----------------+-----------------+
|File |Position |Binlog_Do_DB|Binlog_Ignore_DB|Executed_Gtid_Set|
+-------------+---------+------------+----------------+-----------------+
|binlog.000010|120507544| | | |
+-------------+---------+------------+----------------+-----------------+
3. Binlog is generally under /var/lib/mysql by default, find the latest file binlog.000010 found in the above query
Query and locate according to the approximate time to roll back
mysqlbinlog --no-defaults --database=www_sentgon_com --start-datetime="2022-06-21 09:00:00" --stop-datetime="2022-06-22 13:00:00" /data/mysql/binlog.000010
4. Generate sql according to the queried location
mysqlbinlog --no-defaults --database=www_sentgon_com --start-datetime="2022-06-21 09:00:00" --stop-datetime="2022-06-22 13:00:00" /data/mysql/binlog.000010 > /home/rollback.sql
Alternatively, set the range by position number
mysqlbinlog --no-defaults --start-position="239" --stop-position="736" /data/mysql/binlog.000010 > /home/rollback.sql
5. Execute sql to restore the database
mysqlbinlog --start-position=0 --stop-position=45325593 /data/mysql/binlog.000010 | mysql -utest -p
如果是通过日期时间回滚的命令如下：
mysqlbinlog --start-datetime '2019-07-02 21:42:36' --stop-datetime '2019-07-02 21:57:42' /data/mysql/binlog.000010 | mysql -utest -p
