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).

2022-01-20T03:38:07.018691Z 1 [Note] A temporary password is generated for root@localhost: pE.Yu96:XQEp

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.
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2

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
