- 如果有多个库：
- mysqlbinlog mysqlbin.000021 -d oldboy -r oldboy.sql
- -d ##基于具体库的恢复
- 其他方法：
- 常见命令组合：
- (a)
- mysqlbinlog mysqlbin.000021 --start-datetime='2011-03-19 02:58:54' --stop-datetime='2011-03-19 03:22:44' -r time.sql
- 上面语句将显示2011-03-19 02:58:54---2011-03-19 03:22:44时间段的binlog，并输出到time.sql.
- (b)
- mysqlbinlog mysqlbin.000021 --start-datetime='2011-03-19 02:58:54' -d test -r time.sql
- 这个语句只有开始时间，那么就是从2011-03-19 02:58:54时刻到日志结尾，test数据库的binlog输出到time.sql
- (c)
- mysqlbinlog mysqlbin.000021 --stop-datetime='2011-03-19 03:22:44' -d oldboy -s
- 这个语句只有结束时间，那么就是从日志开头到2011-03-19 03:22:44时刻截止，oldboy数据库的binlog输出.
- --------------------------------------------------------------------------------------------------------------------
- 基于位置点的恢复：
- ※※※※※
- --start-position=# Start reading the binlog at position N. Applies to the
- first binlog passed on the command line.
- --stop-position=# Stop reading the binlog at position N. Applies to the
- last binlog passed on the command line.
- 参数说明：以上两个参数显示指定position点内的binlog日志内容，是非常重要的选项。
- 这个两个选项比时间选项恢复要更精确
- (a)
- mysqlbinlog mysqlbin.000021 --start-position=510 --stop-position=1312 -r pos.sql
- 输出 初始位置510,结束位置1312的所有binlog日志到pos.sql
- 注意：结尾的日志点比较特殊 不会被包含。即输出1312pos以前的binlog。
- (b)
- mysqlbinlog mysqlbin.000021 --start-position=510 -r pos510-end.sql
- 输出 初始位置510,结束位置到文件结尾的所有binlog到pos510-end.sql，当然，你也可以指定库名输出binlog，如：
- mysqlbinlog mysqlbin.000021 --start-position=510 -r pos510-end-oldboy.sql -d oldboy
- (c)
- mysqlbinlog mysqlbin.000021 --stop-position=954 -r start-954.sql
- 输出从文件开始位置，到954位置截止的所有binlog.
- 起始点：# at 510
- # at 510
- #110319 2:58:54 server id 1 end_log_pos 578 Query thread_id=7 exec_time=0 error_code=0
- 结束点：# at 1312
- # at 1312
- #110319 3:22:44 server id 1 end_log_pos 1339 Xid = 81
- mysqlbinlog mysqlbin.000021 --start-position=510 --stop-position=1312 -r pos.sql

- ※1 基于时间点 ※
- ※2 把中间的一两分钟去掉 ※
- ※3 基于位置点 ※
