mysql8.0导入备份_mysql8.0.20配合binlog2sql的配置和简单备份恢复的步骤详解

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

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

owners.

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

mysql> show master status\g;

+------------------+----------+--------------+------------------+-------------------+

+------------------+----------+--------------+------------------+-------------------+

| 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
