作者：一个小小的MySQL DBA
这篇文章主要介绍了mysql8.0.20配合binlog2sql的配置和简单备份恢复的步骤，本文给大家介绍的非常详细，对大家的学习或工作具有一定的参考借鉴价值，需要的朋友可以参考下
第一步 安装
1.安装MySQL
2.安装Python3
[root@localhost /]#yum install python3
3.下载binlog2sql文件到本地（文件在百度云盘）
[root@localhost /]#mkdir tools [root@localhost /]#cd tools [root@localhost tools]# ll total 317440 -rw-r--r--. 1 root root 317440 Sep 21 23:55 binlog2sql.tar [root@localhost tools]#tar -xvf binlog2sql.tar [root@localhost tools]#cd binlog2sql [root@localhost binlog2sql]# ll total 52 drwxr-xr-x. 3 mysql mysql 91 Jun 13 08:14 binlog2sql drwxr-xr-x. 2 mysql mysql 54 Jun 13 07:45 example -rw-r--r--. 1 mysql mysql 35141 Jun 13 07:45 LICENSE -rw-r--r--. 1 mysql mysql 9514 Jun 13 07:45 README.md -rw-r--r--. 1 mysql mysql 54 Jun 13 07:45 requirements.txt drwxr-xr-x. 2 mysql mysql 37 Jun 13 07:45 tests
4.修改binlog2sql中的requirements.txt，把PyMySQL==0.7.11改为0.9.3,保存退出
[root@localhost binlog2sql]# vi requirements.txt PyMySQL==0.9.3 wheel==0.29.0 mysql-replication==0.13
5.安装和检查，确保是0.9.3 不然出错
[root@localhost binlog2sql]# pip3 install -r requirements.txt [root@localhost binlog2sql]# pip3 show pymysql Name: PyMySQL Version: 0.9.3 Summary: Pure Python MySQL Driver Home-page: https://github.com/PyMySQL/PyMySQL/ Author: yutaka.matsubara Author-email: yutaka.matsubara@gmail.com License: "MIT" Location: /usr/local/lib/python3.6/site-packages Requires:
第二步 准备MySQL数据
1.配置文件最好加入安全目录secure-file-priv=/test，重启MySQL
[root@localhost /]# mkdir test [root@localhost /]# chown -R mysql.mysql test [root@localhost mysqldata]#vi my.cnf secure-file-priv=/test basedir=/application/mysql datadir=/data/mysql socket=/data/mysqldata/mysql.sock log_error=/data/mysqldata/mysql8.0.err port=3306 server_id=6 secure-file-priv=/test autocommit=0 log_bin=/data/mysqldata/mysql-bin [root@localhost mysqldata]# systemctl start mysqld
注：每个人都配置文件路径都不一样
2.进入MySQL
Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 11 Server version: 8.0.20 MySQL Community Server - GPL Copyright (c) 2000, 2020, Oracle and/or its affiliates.

第三步 测试 进入binlog2sql目录下的binlog2sql下
[root@localhost binlog2sql]# pwd /tools/binlog2sql/binlog2sql [root@localhost binlog2sql]# ll total 24 -rwxr-xr-x. 1 mysql mysql 7747 Jun 13 07:45 binlog2sql.py -rwxr-xr-x. 1 mysql mysql 11581 Jun 13 07:45 binlog2sql_util.py -rw-r--r--. 1 mysql mysql 92 Jun 13 07:45 __init__.py drwxr-xr-x. 2 mysql mysql 44 Jun 13 07:50 __pycache__
2.开始备份库下的表的操作
2.1 查看刚才数据库csdn下的操作
[root@localhost binlog2sql]# python3 binlog2sql.py -h 192.168.0.112 -P3306 -uroot -p123 -d csdn -t t1 --start-file='mysql-bin.000001' USE b'csdn'; create database csdn; USE b'csdn'; create table t1 (id int); INSERT INTO `csdn`.`t1`(`id`) VALUES (1); #start 609 end 807 time 2020-09-25 02:21:21 INSERT INTO `csdn`.`t1`(`id`) VALUES (2); #start 609 end 807 time 2020-09-25 02:21:21 INSERT INTO `csdn`.`t1`(`id`) VALUES (3); #start 609 end 807 time 2020-09-25 02:21:21 INSERT INTO `csdn`.`t1`(`id`) VALUES (4); #start 609 end 807 time 2020-09-25 02:21:21 INSERT INTO `csdn`.`t1`(`id`) VALUES (5); #start 609 end 807 time 2020-09-25 02:21:21 INSERT INTO `csdn`.`t1`(`id`) VALUES (6); #start 609 end 807 time 2020-09-25 02:21:21 INSERT INTO `csdn`.`t1`(`id`) VALUES (7); #start 609 end 807 time 2020-09-25 02:21:21 INSERT INTO `csdn`.`t1`(`id`) VALUES (8); #start 609 end 807 time 2020-09-25 02:21:21 UPDATE `csdn`.`t1` SET `id`=10 WHERE `id`=1 LIMIT 1; #start 917 end 1095 time 2020-09-25 02:21:39 DELETE FROM `csdn`.`t1` WHERE `id`=3 LIMIT 1; #start 917 end 1183 time 2020-09-25 02:21:48
2.2备份数据库csdn下的操作
[root@localhost binlog2sql]# python3 binlog2sql.py -h 192.168.0.112 -P3306 -uroot -p123 -d csdn -t t1 --start-file='mysql-bin.000001' >/test/binlog2sql.sql
2.3 查看刚才备份的sql文件
[root@localhost binlog2sql]# cat /test/binlog2sql.sql USE b'csdn'; create database csdn; USE b'csdn'; create table t1 (id int); INSERT INTO `csdn`.`t1`(`id`) VALUES (1); #start 609 end 807 time 2020-09-25 02:21:21 INSERT INTO `csdn`.`t1`(`id`) VALUES (2); #start 609 end 807 time 2020-09-25 02:21:21 INSERT INTO `csdn`.`t1`(`id`) VALUES (3); #start 609 end 807 time 2020-09-25 02:21:21 INSERT INTO `csdn`.`t1`(`id`) VALUES (4); #start 609 end 807 time 2020-09-25 02:21:21 INSERT INTO `csdn`.`t1`(`id`) VALUES (5); #start 609 end 807 time 2020-09-25 02:21:21 INSERT INTO `csdn`.`t1`(`id`) VALUES (6); #start 609 end 807 time 2020-09-25 02:21:21 INSERT INTO `csdn`.`t1`(`id`) VALUES (7); #start 609 end 807 time 2020-09-25 02:21:21 INSERT INTO `csdn`.`t1`(`id`) VALUES (8); #start 609 end 807 time 2020-09-25 02:21:21 UPDATE `csdn`.`t1` SET `id`=10 WHERE `id`=1 LIMIT 1; #start 917 end 1095 time 2020-09-25 02:21:39 DELETE FROM `csdn`.`t1` WHERE `id`=3 LIMIT 1; #start 917 end 1183 time 2020-09-25 02:21:48
3.单独查看删除语句
[root@localhost binlog2sql]# python3 binlog2sql.py -h 192.168.0.112 -P3306 -uroot -p123 -d csdn -t t1 --start-file='mysql-bin.000001' --sql-type=delete USE b'csdn'; create database csdn; USE b'csdn'; create table t1 (id int); DELETE FROM `csdn`.`t1` WHERE `id`=3 LIMIT 1; #start 917 end 1183 time 2020-09-25 02:21:48
4.把删除语句反转保存到sql文件中，并且查看
[root@localhost binlog2sql]# python3 binlog2sql.py -h 192.168.0.112 -P3306 -uroot -p123 -d csdn -t t1 --start-file='mysql-bin.000001' --sql-type=delete --start-position=917 --stop-position=1183 -B >/test/roll.sql [root@localhost binlog2sql]# cat /test/roll.sql INSERT INTO `csdn`.`t1`(`id`) VALUES (3); #start 917 end 1183 time 2020-09-25 02:21:48
5.进入MySQL，恢复被删除的数据
mysql> source /test/roll.sql Query OK, 1 row affected (0.00 sec) mysql> select * from t1; +------+ | id | +------+ | 10 | | 2 | | 4 | | 5 | | 6 | | 7 | | 8 | | 3 | +------+ 8 rows in set (0.00 sec)
