1、搭建初始化数据库
2、确定日志的位置position
3、备份数据库T0
4、模拟数据库发生变化T1
5、模拟数据库发生变化T2
6、恢复数据库到备份时间点T0
7、模拟数据库恢复到时间点T1
8、模拟数据库恢复到时间点T2
1、安装数据库，安装xtrabackup
a、安装数据库及初始化数据这里就不在重复了，初始化后数据库如下：
MariaDB [(none)]> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| MySQL |
| performance_schema |
| test |
| ty |
+--------------------+
5 rows in set (0.00 sec)
MariaDB [(none)]> use ty
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
MariaDB [ty]> show tables;
+--------------+
| Tables_in_ty |
+--------------+
| APP_GROUPS |
| APP_MEMBER |
| APP_ORG |
| APP_OTAURL |
| APP_ROLE |
+--------------+
5 rows in set (0.00 sec)
MariaDB [ty]> select count(*) from APP_MEMBER;
+----------+
| count(*) |
+----------+
| 3 |
+----------+
1 row in set (0.00 sec)
MariaDB [ty]> select count(*) from APP_OTAURL;
+----------+
| count(*) |
+----------+
| 47 |
+----------+
1 row in set (0.00 sec)
---其他表也有数据，但是不多，我们测试时不做任何改变，所以这里就不查询出来了。
b、安装xtrabackup，这里一定要选择和自己数据库版本对应的xtrabackup版本
yum install libaio curl numactl zlib zlib-devel openssl openssl-devel perl cpio expat expat-devel gettext gettext-devel perl-ExtUtils-MakeMaker perl-DBD-MySQL package -y
rpm -ivh libev-4.15-1.el6.rf.x86_64.rpm
----libev建议使用RPM安装，否则容易触发Bug。
rpm -ivh percona-xtrabackup-24-2.4.4-1.el6.x86_64.rpm
2、确定日志的位置position
MariaDB [ty]> show variables like 'log_bin';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| log_bin | ON |
+---------------+-------+
1 row in set (0.00 sec)
MariaDB [ty]> show master status;
+------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000001 | 312 | | |
+------------------+----------+--------------+------------------+
1 row in set (0.00 sec)
3、备份数据库T0
