第一步安装

1.安装MySQL

2.安装Python3

1	`[root@localhost` `/` `]` `#yum install python3`

3.下载binlog2sql文件到本地（文件在百度云盘）

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 [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

1 2 3 4 [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

1 2 3 4 5 6 7 8 9 10 11 [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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 [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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 Welcome to the MySQL monitor. Commands end with ; or \g.

第三步测试进入binlog2sql目录下的binlog2sql下

1 2 3 4 5 6 7 8 [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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 [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

1	`[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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 [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

1 2 3 4 5 6 [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

1 2 3 [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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 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)
