篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Windows环境下部署MySQL主从并模拟升级到8.0相关的知识，希望对你有一定的参考价值。
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.zip2.解压一下
3.初始化
- 记录下秘钥
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). 2022-01-20T03:38:03.808644Z 0 [Warning] InnoDB: New log files created, LSN=45790 2022-01-20T03:38:03.901775Z 0 [Warning] InnoDB: Creating foreign key constraint system tables. 2022-01-20T03:38:04.079914Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: 5fd0428e-79a2-11ec-b336-00155d9ebf27. 2022-01-20T03:38:04.092275Z 0 [Warning] Gtid table is not ready to be used. Table mysql.gtid_executed cannot be opened. 2022-01-20T03:38:05.824394Z 0 [Warning] A deprecated TLS version TLSv1 is enabled. Please use TLSv1.2 or higher. 2022-01-20T03:38:05.824844Z 0 [Warning] A deprecated TLS version TLSv1.1 is enabled. Please use TLSv1.2 or higher. 2022-01-20T03:38:05.826505Z 0 [Warning] CA certificate ca.pem is self signed. 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
- 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.修改秘钥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;
1. row

# 三、升级8.0
## 1.署mysql8d:\\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2022-01-20T17:33:33.598491+08:00 2 [System] [MY-011003] [Server] Finished populating Data Dictionary tables with data.2022-01-20T17:33:37.652733+08:00 5 [System] [MY-013381] [Server] Server upgrade from 50700 to 80026 started.2022-01-20T17:33:53.602051+08:00 5 [System] [MY-013381] [Server] Server upgrade from 50700 to 80026 completed.
Enjoy GreatSQL :)
