说明：
一般来说，如果恢复的binlog量不大，可以使用此方法来恢复：
mysqlbinlog /data/mysqlbak/binlogbak/restoredb-bin.000018 |mysql -u root -pchengce243
但是如果binlog量非常大，使用此方法会非常慢，下面介绍一种方法，让MySQL模拟成slave恢复，速度非常快。
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
多切换几次 binlog日志
mysql> flush logs;
[root@restoredb ~]# ll /data/mysql/*bin*

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/
[root@restoredb mysql]# ll /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 binlog 和pos点
[root@restoredb mysql]# cat xtrabackup_binlog_info
restoredb-bin.000001 154
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
开始恢复binlog日志
使用模拟slave的方式恢复binlog
修改relay-log.info里面配置，修改第二行和第三行，第二行指定文件，第三行指定POS点。
mysql> change master to master_host='192.168.190.27',master_user='root',master_password='chengce243',master_port=3306,master_log_file='/data/mysqlbak/binlogbak/restoredb-bin.000001',master_log_pos=154;
mysql> start slave sql_thread;
mysql> start slave until MASTER_LOG_FILE = '/data/mysqlbak/binlogbak/restoredb-bin.000001', MASTER_LOG_POS = 154;
如果是使用GTID，则使用如下类似命令：
mysql> start slave until SQL_BEFORE_GTIDS ='96359478-a845-11e6-a3d6-000c296e817a:44'
可以使用 SQL_BEFORE_GTIDS 或者 SQL_AFTER_GTIDS
START SLAVE SQL_THREAD UNTIL SQL_BEFORE_GTIDS = 96359478-a845-11e6-a3d6-000c296e817a:11-56
表示，当SQL_thread 执行到96359478-a845-11e6-a3d6-000c296e817a:10 的时候停止，下一个事务是11
START SLAVE SQL_THREAD UNTIL SQL_AFTER_GTIDS = 3E11FA47-71CA-11E1-9E33-C80AA9429562:11-56
表示，当SQL_thread 执行到3E11FA47-71CA-11E1-9E33-C80AA9429562:56 的时候停止，56是最后一个提交的事务。
查看数据
mysql> select *from testtab;
+-------+-----------+
| id | name |
+-------+-----------+
| 10000 | test |
| 10001 | incr_bak |
| 10002 | incr_bak2 |
| 20001 | full_bak |
| 20002 | full_bak2 |
| 20003 | full_bak3 |
+-------+-----------+
6 rows in set (0.01 sec)
发现已经是最新的数据，已经恢复过来。
