innobackupex基于binlog日志的恢复 -- 使用mysqlbinlog恢复
备份
先做一次完整备份：
innobackupex --defaults-file=/etc/my.cnf --user root --password chengce243 /data/mysqlbak
执行完命令后，/data/mysqlbak 目录下会生成目录： 2018-08-06_14-19-12
记下操作后的 position 点
mysql> show master status;
+----------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+----------------------+----------+--------------+------------------+-------------------+
| restoredb-bin.000001 | 154 | | | |
+----------------------+----------+--------------+------------------+-------------------+
1 row in set (0.00 sec)
多切换几次 binlog日志
mysql> flush logs;

插入测试数据
insert into testtab values (20001,'full_bak');
多切换几次 binlog日志
mysql> flush logs;
再插入测试数据
insert into testtab values (20002,'full_bak2');

再插入测试数据
insert into testtab values (20003,'full_bak3');
停止MySQL服务并清空数据目录：
/etc/init.d/mysqld stop
备份binlog（正常情况下，这些binlog会备份到binlog server，此处用复制模拟binlog server备份路径）。
[root@restoredb mysql]# cp *bin* /data/mysqlbak/binlogbak/

清空数据文件
rm -rf /data/mysql/*
恢复
直接复制 /data/mysqlbak/2018-08-06_14-19-12 目录下文件到 /data/mysql 目录下，然后修改权限
cp -r /data/mysqlbak/2018-08-06_14-19-12/* /data/mysql/
chown -R mysql:mysql /data/mysql
直接启动数据
/etc/init.d/mysqld start
查看此时的testtab表：
mysql> select *from testtab;
+-------+-----------+
| id | name |
+-------+-----------+
| 10000 | test |
| 10001 | incr_bak |
| 10002 | incr_bak2 |

测试数据 (20001,'full_bak')并不存在，说明binlog日志的数据并没有恢复
