binlog2sql闪回工具的使用

一、下载安装依赖的python

yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel 
yum install python34 -y
python3 --version
wget --no-check-certificate https://bootstrap.pypa.io/get-pip.py
python3 get-pip.py
pip3 -V

切换升级本地python版本

python -V; python2.6 -V     
# 查看当前python版本 这两个应该都是原始的2.6.x
ls -hli /usr/bin/python*
cp -f /usr/bin/python2.6 /usr/bin/python2.6.bak
rm -f /usr/bin/python /usr/bin/python
cp /usr/bin/python3.4 /usr/bin/python
ls -hli /usr/bin/python*
python -V; python2.6 -V 
# 验证python版本是否OK(python->2.7, python2.6->python2.6.x)


yum -h # 验证yum已经不可用,命令会出错退出
head -n 2 /usr/bin/yum
sed -i ‘s/python$/&2\.6/‘ /usr/bin/yum
head -n 2 /usr/bin/yum    
# 将/usr/bin/yum 中的python 替换为python2.6
yum -h # 验证yum可用,此时不会再出错退出

二、安装binlog2sql

# 参考资料：https://www.runoob.com/w3cnote/python-pip-install-usage.html
cd /opt/
yum -y install  python-pip
git clone https://github.com/danfengcao/binlog2sql.git && cd binlog2sql
pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple

  --back-interval BACK_INTERVAL
                        Sleep time between chunks of 1000 rollback sql. set it
                        to 0 if do not need sleep

connect setting:
  -h HOST, --host HOST  Host the MySQL database server located
  -u USER, --user USER  MySQL Username to log in as
  -p [PASSWORD [PASSWORD ...]], --password [PASSWORD [PASSWORD ...]]
                        MySQL Password to use
  -P PORT, --port PORT  MySQL port to use

interval filter:
  --start-file START_FILE
                        Start binlog file to be parsed
  --start-position START_POS, --start-pos START_POS
                        Start position of the --start-file
  --stop-file END_FILE, --end-file END_FILE
                        Stop binlog file to be parsed. default: ‘--start-file‘
  --stop-position END_POS, --end-pos END_POS
                        Stop position. default: latest position of ‘--stop-
                        file‘
  --start-datetime START_TIME
                        Start time. format %Y-%m-%d %H:%M:%S
  --stop-datetime STOP_TIME
                        Stop Time. format %Y-%m-%d %H:%M:%S;

schema filter:
  -d [DATABASES [DATABASES ...]], --databases [DATABASES [DATABASES ...]]
                        dbs you want to process
  -t [TABLES [TABLES ...]], --tables [TABLES [TABLES ...]]
                        tables you want to process

 三、使用该工具的前提

1. binlog_format为ROW，且binlog_row_image为full或noblog，默认为full。

2. 必须开启MySQL Server，理由有如下两点：

   1> 它是基于BINLOG_DUMP协议来获取binlog内容

   2> 需要读取server端information_schema.COLUMNS表，获取表结构的元信息，拼接成可视化的sql语句

该工具所需权限如下：

mysql> GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO ‘flashbak_user‘@‘%‘ identified by ‘flashbak_user_pwd‘;

**权限说明**
* select：需要读取server端information_schema.COLUMNS表，获取表结构的元信息，拼接成可视化的sql语句
* super/replication client：两个权限都可以，需要执行‘SHOW MASTER STATUS‘, 获取server端的binlog列表
* replication slave：通过BINLOG_DUMP协议获取binlog内容的权限

因为是伪装成slave来获取主的二进制事件，故无需对binlog有可读权限。

四、测试验证

4-1、创建测试表

# 创建测试表
CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(10) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8mb4;

insert into user(name) values(‘小赵‘);
insert into user(name) values(‘小王‘);
insert into user(name) values(‘小李‘);
insert into user(name) values(‘小钱‘);
insert into user(name) values(‘小孙‘);

mysql> select * from user;
+----+--------+
| id | name   |
+----+--------+
|  6 | 小赵   |
|  7 | 小王   |
|  8 | 小李   |
|  9 | 小钱   |
| 10 | 小孙   |
+----+--------+
5 rows in set (0.00 sec)

4-2、update回滚实践

# update误操作闪回
mysql> update user set name=‘王源‘ where id=8;
Query OK, 1 row affected (0.07 sec)
Rows matched: 1  Changed: 1  Warnings: 0
