2018年的吧
测试环境
- 系统：WIN 10
- MySQL版本：mysql-5.7.23
安装配置
解压文件
使用mysql-5.7.23-winx64.zip包解压缩安装
路径分别为：
- D:\mysql\mysql-5.7.23-winx64
- D:\mysql\mysql-5.7.23-winx64-3307
解压安装路径随意指定，注意需要与my.ini文件中的路径一致
my.ini配置文件
分别在两个目录中创建my.ini 文件
在同一台机器上测试，mysql实例使用不同端口
主数据库：3306 (默认)
从数据库：3307
内容如下：
主库my.ini
[mysqld]
# set basedir to your installation path
basedir=D:/mysql/mysql-5.7.23-winx64
# set datadir to the location of your data directory
datadir=D:/mysql/mysql-5.7.23-winx64/data
# 唯一标识
server-id=1
# binlog文件名
log-bin=mysql-binlog
# 要写binlog的数据库，要同步多个数据库，就多加几个binlog-do-db=数据库名
binlog-do-db=mstest
binlog-do-db=test
# 要忽略的数据库
binlog-ignore-db=mysql
从库my.ini
[mysqld]
# 指定端口
port=3307
# set basedir to your installation path
basedir=D:/mysql/mysql-5.7.23-winx64-3307
# set datadir to the location of your data directory
datadir=D:/mysql/mysql-5.7.23-winx64-3307/data
# 唯一标识
server-id=2
# 要复制多个数据库，就多加几个replicate-do-db=数据库名
replicate-do-db=mstest
replicate-do-db=test
# 要忽略的数据库
replicate-ignore-db=mysql
初始化并启动数据库
分别初始化、启动两个数据库，并修改root密码
mysqld --initialize --console
mysqld.exe --console
ALTER USER 'root'@'localhost' IDENTIFIED BY 'root';
具体见安装文档
数据库配置
主库配置
登录主库
>mysql -uroot -p
主数据库创建用于同步的用户
GRANT REPLICATION SLAVE ON *.* TO 'mstest'@'%' IDENTIFIED BY '123456';
从数据库配置
登录从库，指定端口3307
>mysql -uroot -p -P3307
配置从库连接到主库
change master to master_host='127.0.0.1',master_port=3306,
master_user='mstest',master_password='123456';
start slave;
查看状态
