【MySQL】Windows下mysql的主从配置笔记

第一步，安装多个mysql

先停止mysql服务，将C:\ProgramData\MySQL\MySQL Server 5.7\Data文件夹复制到新建的文件夹，比如：

E:\MySQL\MySQL3307

同时在文件夹Mysql3307中新建文件my.ini,内容如下

[mysql]
character-set-server = utf8

[mysqld]
port = 3307
server_id = 3307
basedir=E:\MySQL\MySQL3307
datadir=E:\MySQL\MySQL3307\Data

max_connections=200
character-set-server=utf8
default-storage-engine=INNODB
log_error=error.log
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES 

并修改 E:\MySQL\MySQL3307\Data中的auto.cnf，修改server-uuid

 

然后安装成服务

mysqld -install MySQL3307 --defaults-file="E:\MySQL\MySQL3307\my.ini"

启动服务 net start MySQL3307，测试登录数据库

mysql -uroot -p -P3307

以上就是安装多个MySQL的步骤了。

 

第二步：MySQL的Master-Slave配置

首先配置Master，找到C:\ProgramData\MySQL\MySQL Server 5.7\my.ini,  找到 # Error Logging位置，改之前

# Error Logging.
log-error="iZgaj0ka5j3mumZ.err"

# Server Id.
server-id=1

改之后为

# Error Logging.
log-error="iZgaj0ka5j3mumZ.err"
log-bin=C:/ProgramData/MySQL/MySQL Server 5.7/mysql-bin
sync_binlog=1

# Server Id.
server-id=1

修改完成，重启主MySQL服务，执行

show master status \G;

查看结果如下（其中File和Position的值后续会用到）

mysql> show master status \G;
*************************** 1. row ***************************
File: mysql-bin.000001
Position: 1119
Binlog_Do_DB:
Binlog_Ignore_DB:
Executed_Gtid_Set:
1 row in set (0.00 sec)

ERROR:
No query specified

 接着配置从Mysql，在上面安装多个MySql的基础上，修改 E:\MySQL\MySQL3307\my.ini  最新配置如下

[mysql]
character-set-server = utf8

[mysqld]
port = 3307
server_id = 3307
basedir=E:\MySQL\MySQL3307
datadir=E:\MySQL\MySQL3307\Data
log-bin=mysql-bin
log-bin-index=mysql-bin.index
sync_binlog=1
binlog_format=mixed
binlog-do-db = test_db

max_connections=200
character-set-server=utf8
default-storage-engine=INNODB
log_error=error.log
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES 

重启从MySql服务，执行如下命令

mysql> stop slave;

mysql> CHANGE MASTER TO MASTER_HOST='localhost',
MASTER_USER='root',
MASTER_PASSWORD='123456',
MASTER_LOG_FILE='mysql-bin.000001',
MASTER_LOG_POS=1119;

mysql> start slave;

mysql> show slave status \G;

 

如下表示正常运行

Slave_IO_Running: Yes

Slave_SQL_Running: Yes
