1.Percona 介绍

Percona Server由领先的MySQL咨询公司Percona发布。 Percona Server是一款独立的数据库产品，其可以完全与MySQL兼容，可以在不更改代码的情况了下将存储引擎更换成XtraDB 。

Percona团队的最终声明是“Percona Server是由Oracle发布的最接近官方MySQL Enterprise发行版的版本”，因此与其他更改了大量基本核心MySQL代码的分支有所区别。 Percona Server的一个缺点是他们自己管理代码，不接受外部开发人员的贡献，以这种方式确保他们对产品中所包含功能的控制。
Percona提供了高性能XtraDB引擎，还提供PXC高可用解决方案，并且附带了perconatoolkit等DBA管理工具箱

切换到 /xtrabackup/full目录下，查看备份目录。数据库，配置文件，日志文件

[root@mysql-server ~]# cd  /xtrabackup/full
[root@mysql-server full]# ls

[root@mysql-server full]# ls /xtrabackup/full/2022-11-05_21-04-58

观察二进制日志位置

[root@mysql-server full]# cat /xtrabackup/full/2022-11-05_14-26-08/xtrabackup_binlog_info

导入文本文件

删除表的内容：因为表的导出和导入只备份表记录，不会备份表的结构。因此需要通过 mysqldump 备份表的结构，恢复时先恢复表结构，在导入数据。

10.mysqldump+binlog

优势：

1.自动记录日志position位置 
2.可用性，一致性

语法：

mysqldump -h 服务器 -u用户名 -p密码 数据库名 >  备份文件.sql

参数说明：

--single-transaction  #InnoDB 一致性 服务可用性
--master-data=1|2  #该选项将会记录binlog的日志位置与文件名并追加到文件中。

库的范围

帮助

[root@mysql-server ~]#mysqldump --help

备份练习

1.准备两套密码分别为123456和guan123456
2.准备库 testdb

执行备份

[root@mysql-server ~]# rm -rf  /backup
[root@mysql-server ~]# mkdir /backup
[root@mysql-server ~]# ls /backup

[root@mysql-server ~]# date +%F-%H    //一种时间输出格式
2022-111-08-00
 
//这里有个错误提醒，二进制日志没开启
[root@mysql-server ~]# mysqldump -uroot -p'123456' --all-databases --single-transaction --master-data=2 --flush-logs >  /backup/`date +%F-%H`mysql-all.sql
mysqldump: [Warning] Using a password on the command line interface can be insecure.
mysqldump: Error: Binlogging on server not active


在进行mysqldump备份的时候报错：

mysqldump: Couldn't execute 'SHOW VARIABLES LIKE 'gtid\_mode'': Table 'performance_schema.session_variables' doesn't exist (1146)
1


检查performance_schema 数据库发现不存在

原因：可能是升级导致该表损坏或者误删除

解决方法：
执行下面的命令，重新生成了sys、performance_schema数据库


mysql_upgrade -u root -p --force

重启mysqld
[root@mysql-server ~]# systemctl restart mysqld
 
//开启二进制日志

[root@localhost ~]# vim /etc/my.cnf    //在里面添加下面的内容
[mysqld]
log_bin=mysql_bin
server_id=1
 
[root@mysql-server ~]# systemctl restart mysqld    //重启数据库
[root@mysql-server ~]# mysql -uroot -p'123456'    //登录数据库查看一下二进制日志状态，ON就是开启成功

观察备份数据

[root@mysql-server ~]# vim /backup/2022-11-08-13mysql-all.sql

//在前面备份时如果写的是master-data=1,那么在CHANGE MASTER TO MASTER_LOG_FILE='mysql_bin.000001', MASTER_LOG_POS=154的前面就不会有注释了
[root@mysql-server ~]# vim /backup/2022-11-08-13mysql-all.sql
//第22行可以看到mysql_bin.0000001,在/etc/lib/mysql里面有对应的文件
22 -- CHANGE MASTER TO MASTER_LOG_FILE='mysql_bin.000001', MASTER_LOG_POS=154;
 
LOCK TABLES `columns_priv` WRITE;    //观察各种锁机制，用来保证数据的一致性
/*!40000 ALTER TABLE `columns_priv` DISABLE KEYS */;
/*!40000 ALTER TABLE `columns_priv` ENABLE KEYS */;
UNLOCK TABLES;

备份之后数据又有变更了

模拟清理环境

[root@mysql-server ~]# rm -rf /var/lib/mysql/*
root@mysql-server ~]# ls /var/lib/mysql
[root@mysql-server ~]# 

启动数据库

[root@mysql-server ~]# systemctl start mysqld
[root@mysql-server ~]# grep password /var/log/mysqld.log 
2022-11-08T06:13:24.764470Z 1 [Note] A temporary password is generated for root@localhost: jCCzW8jNPw>f


//这里更改一下数据库的密码可以更直观的感受到数据库恢复数据的过程
[root@mysql-server ~]# mysqladmin -uroot -p're%f<7H1bi7s' password 'guan123456'
装完mysql启动服务，第一次使用需要重置密码，显示我输入的密码"guan123456"太简单,在个人练习过程中，不想把密码设置太复杂

[root@mysql-server ~]# grep password /var/log/mysql.log

2022-11-08T06:13:24.764470Z 1 [Note] A temporary password is generated for root@localhost: jCCzW8jNPw>f
# mysqladmin -uroot -p"jCCzW8jNPw>f" password "guan123456"
mysqladmin: [Warning] Using a password on the command line interface can be insecure.
Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.
mysqladmin: unable to change password; error: 'Your password does not satisfy the current policy requirements'

解决方案：

# mysql -uroot -p'jCCzW8jNPw>f'

(1)修改validate_password_policy参数值为0(1为开启复杂策略)

注意：此参数(policy)必须优先修改，因为policy策略不修改为0会影响下面的length参数。

mysql> set global validate_password_policy=0;

(2)修改validate_password_length参数值为1

mysql> set global validate_password_length=1;

退出重新修改密码

mysql > exit;

[root@mysql-server ~]# mysqladmin -uroot -p'jCCzW8jNPw>f' password'guan123456'


[root@mysql-server ~]# mysql -uroot -p'guan123456'

12.二进制日志恢复

观察二进制截取记录

如果在备份之后又操作了数据库，那么这些数据是没有备份的，想要恢复可以通过恢复二进制日志来恢复备份之后的一些操作

[root@mysql-server ~]# vim /backup/2022-11-08-13mysql-all.sql
-- CHANGE MASTER TO MASTER_LOG_FILE='mysql_bin.000001', MASTER_LOG_POS=154;
 
//mysql_bin.000000就不用写了，这里的数据要看2022-11-08-13mysql-all.sql
//在/etc/lib/mysql,里面有多少个二进制日志文件就要在mysql_bin.000001后面跟着增加多少个二进制文件

[root@mysql-server ~]# cp /var/lib/mysql/*bin* .
[root@mysql-server ~]# ls
anaconda-ks.cfg    mysql_bin.000001  mysql_bin.index  mysql_bin.000002




[root@mysql-server ~]# mysqlbinlog mysql_bin.000001 --start-position=154 | mysql -uroot -p'123456'
mysql: [Warning] Using a password on the command line interface can be insecure.

//假如说在/etc/lib/mysql里面有mysql_bin.000001  mysql_bin.000002  mysql_bin.000003那么就要这样写
[root@mysql-server ~]# mysqlbinlog mysql_bin.000002  mysql_bin.000003 --start-position154 | mysql -uroot -p'123456'
mysql: [Warning] Using a password on the command line interface can be insecure.

观察数据库是否恢复完整

[root@mysql-server ~]# mysql -uroot -p'guan123456'
mysql: [Warning] Using a password on the command line interface can be insecure.
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
[root@mysql-server ~]# mysql -uroot -p'123456'

mysql> select * from testdb2.test2;
+------+
| id   |
+------+
|   1  |
|   2  |
|   3  |
+------+
3 rows in set (0.00 sec)

13.误删除库的问题

如何保留人为删除的testdb3库(这种问题，能避就避)

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| sys                |
| testdb             |
| testdb3            |
| zabbix             |
+--------------------+
7 rows in set (0.00 sec)




mysql> desc testdb3.test3;
+-------+-------------+------+-----+---------+-------+
| Field | Type        | Null | Key | Default | Extra |
+-------+-------------+------+-----+---------+-------+
| id    | int(100)    | YES  |     | NULL    |       |
| name  | varchar(20) | YES  |     | NULL    |       |
+-------+-------------+------+-----+---------+-------+
2 rows in set (0.02 sec)


mysql> drop database testdb3;
Query OK, 1 row affected (0.03 sec)

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| sys                |
| testdb             |
| zabbix             |
+--------------------+
6 rows in set (0.01 sec)

mysql> quit;
Bye

[root@mysql-server ~]# mysqlbinlog mysql_bin.000001 mysql_bin.000002 ..bin.003.. ..bin.004.. > log.txt
[root@mysql-server ~]# vim log.txt  #找到删除testdb3的记录,并将删除testdb3的记录从log.tex文件中删除
...
drop database testdb3
...

[root@mysql-server ~]# cat log.txt | mysql -p'123456' #将删除testdb3的记录去除后还原到mysql中，可能会包库已存在的错误

//需要清理环境
[root@mysql-server ~]# systemctl stop mysqld
[root@mysql-server ~]# rm -rf /var/lib/mysql/*
[root@mysql-server ~]# ls /var/lib/mysql/
//进行mysqldump还原
[root@mysql-server ~]# systemctl start mysqld
[root@mysql-server ~]# grep password /var/lib/mysqld.log
[root@mysql-server ~]# mysqladmin -uroot -p'jCCzW8jNPw>f' password'123456'
[root@mysql-server ~]# mysql -uroot -p'123456'
[root@mysql-server ~]# mysql -uroot -p'123456' < /backup/2022-11-08-13mysql-all.sql  #完整
[root@mysql-server ~]# cat log.txt | mysql -p'123456'  #二进制还原

14.数据库恢复时的多余日志

mysql> set sql_log_bin=0;  //暂时关闭二进制日志文件
Query OK, 0 rows affected (0.00 sec)
mysql> source /backup/*.sql  //读取二进制文件
mysql> set sql_log_bin=1;  //读取二进制日志文件完后，开启二进制日志文件
Query OK, 0 rows affected (0.00 sec)
