MySQL主从复制：同一台电脑Windows环境下如何搭建MySQL主从复制文章目录前言主从原理一、准备工作二、搭建步骤总结前言一般我们在服务器上做数据库集群部署的时候都是需要最少两台物理机器。那么我们做为个人学习或者模拟搭建的时候，就可以参考这篇博文，实现一台物理机照样搭建好MySQL主从环境主从原理 MySQL主从复制是依靠bin-log二进制文件来完成的。主库开启biglog日志后，每一条执行过的新增和修改语句，都会被记录到biglog日志里。然后从库会监听这个文件，一旦发现biglog文件有改动，则会起一个线程将biglog日志文件拉到从库环境并执行。从而达到数. 阅读详情

一、部署实例

1.下载2个软件

http://ftp.kaist.ac.kr/mysql/Downloads/MySQL-5.7/mysql-5.7.35-winx64.zip
http://ftp.kaist.ac.kr/mysql/Downloads/MySQL-8.0/mysql-8.0.26-winx64.zip

2.解压一下

file

3.初始化

记录下密码

C:\Users\Administrator>D:\test\mysql-5.7.35-winx64\bin\mysqld --initialize --console
2022-01-20T03:37:59.769162Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).

初始化数据如下图，默认是在安装程序的data目录下面

file

把初始化的数据拷贝到自定义的数据目录。
添加下my.ini配置

[mysqld]
port=3306
character_set_server=utf8
basedir=D:/test/mysql-5.7.35-winx64
datadir=D:/test/data3306
server-id=1
sql_mode=NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
lower_case_table_names=1
innodb_file_per_table = 1
log_timestamps=SYSTEM

log-error = error.log
slow_query_log = 1
slow_query_log_file = slow.log
long_query_time = 5
log-bin = binlog
binlog_format = row
expire_logs_days = 15
log_bin_trust_function_creators = 1

[client]   
default-character-set=utf8

4.安装服务

C:\Users\Administrator>D:\test\mysql-5.7.35-winx64\bin\mysqld --install mysql3306 --defaults-file=D:\test\data3306\my.ini
Service successfully installed.

5.开启

C:\Users\Administrator>net start mysql3306
mysql3306 服务正在启动 .
mysql3306 服务已经启动成功。

--------------------------------以上安装了一个3306，依葫芦画瓢再安装一个3307----------------------------------

D:\test\mysql-5.7.35-winx64\bin\mysqld --initialize --console
2022-01-20T05:38:55.054718Z 1 [Note] A temporary password is generated for root@localhost: E)+H2UUpeJRf
D:\test\mysql-5.7.35-winx64\bin\mysqld --install mysql3307 --defaults-file=D:\test\data3307\my.ini
mysql3307 服务正在启动 .
mysql3307 服务已经启动成功。

查看服务信息

6.修改密码

C:\Users\Administrator>cd /d d:\test\mysql-5.7.35-winx64\bin
d:\test\mysql-5.7.35-winx64\bin>mysql -uroot -ppE.Yu96:XQEp
mysql: [Warning] Using a password on the command line interface can be insecure.

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'GreatSQL';
Query OK, 0 rows affected (0.01 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)

# 然后重新登陆一下
d:\test\mysql-5.7.35-winx64\bin>mysql -uroot -p"GreatSQL" -P3307

二、建立主从

1.主节点建表等

mysql> create table t1(id int(1) not null auto_increment , name varchar(64),primary key(id));
Query OK, 0 rows affected (0.06 sec)

mysql> insert into t1 values(1,'GreatSQL');
Query OK, 1 row affected (0.01 sec)

2.迁移数据

d:\test\mysql-5.7.35-winx64\bin>mysqldump.exe -uroot -pGreatSQL -P3306 --single-transaction --master_data=2 --set-gtid-purged=OFF --databases test > d:\test.sql
mysqldump: [Warning] Using a password on the command line interface can be insecure.

d:\test\mysql-5.7.35-winx64\bin>mysql -uroot -pGreatSQL -P3307 < d:\test.sql
mysql: [Warning] Using a password on the command line interface can be insecure.

3.主节点赋权

CREATE USER `sync`@`127.0.0.1` IDENTIFIED BY 'sync';
GRANT Replication Slave ON *.* TO `sync`@`127.0.0.1`;
flush privileges;

4.看下dump文件的pos值

d:\test\mysql-5.7.35-winx64\bin>more d:\test.sql
-- MySQL dump 10.13  Distrib 5.7.35, for Win64 (x86_64)
......
-- Current Database: `test`
-- CHANGE MASTER TO MASTER_LOG_FILE='binlog.000002', MASTER_LOG_POS=1350;

5.从节点建立同步

change master to master_host="127.0.0.1",master_port=3306,MASTER_USER='sync',MASTER_PASSWORD='sync',MASTER_LOG_FILE='binlog.000002', MASTER_LOG_POS=1350;
start slave;

6.完成同步

mysql> show slave status\G;

三、升级8.0

1.署mysql8

d:\test\mysql-5.7.35-winx64\bin>D:\test\mysql-8.0.26-winx64\bin\mysqld --install
mysql8_3307 --defaults-file=D:\test\data3306\my.ini
Service successfully installed.

2.停掉原来的

d:\test\mysql-5.7.35-winx64\bin>net stop mysql3307
mysql3307 服务正在停止.
mysql3307 服务已成功停止。

3.修改下配置

[mysqld]
port=3307
character_set_server=utf8
basedir=D:/test/mysql-8.0.26-winx64  #路径改了
datadir=D:/test/data3307   
server-id=2
sql_mode=NO_ENGINE_SUBSTITUTION #sql_mode 改了
lower_case_table_names=1
innodb_file_per_table = 1
log_timestamps=SYSTEM

log-error = error.log
slow_query_log = 1
slow_query_log_file = slow.log
long_query_time = 5
log-bin = binlog
binlog_format = row
expire_logs_days = 15
log_bin_trust_function_creators = 1

[client]   
default-character-set=utf8

4.开启服务，会自动升级

net start mysql8_3307

5.查看日志升级成功了
