mysql8.0.20配合binlog2sql的配置和简单备份恢复的步骤详解 目录
  • 第一步 安装
  • 第二步 准备MySQL数据
  • 第三步 测试 进入binlog2sql目录下的binlog2sql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/

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

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> show master status\g;
+------------------+----------+--------------+------------------+-------------------+
| File  | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+-------------------+
| mysql-bin.000001 | 156 |  |   |   |
+------------------+----------+--------------+------------------+-------------------+

mysql> create database csdn;
mysql> use csdn
mysql> insert into t1 values(1),(2),(3),(4),(5),(6),(7),(8);
mysql> commit;
mysql> update t1 set id=10 where id=1;
mysql> delete from t1 where id=3;
mysql> commit;

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 *** 作
2.1 查看刚才数据库csdn下的 *** 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 *** 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)
