【mysql】windows中Mysql搭建主从复制

主库增加我们的serverId和binlog日志配置：
[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8
[mysqld]
#设置3306端口
port = 3306
# 设置mysql的安装目录
basedir=D:\\KaiFaGongJu\\mysql-5.7.40-winx64
# 允许最大连接数
max_connections=200
# 服务端使用的字符集默认为8比特编码的latin1字符集
character-set-server=utf8
# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB

#开启日志
log-bin = mysql-bin
#设置服务id，主从不能一致
server-id = 1
#设置需要同步的数据库
binlog-do-db=store_db
binlog-do-db=product_db_1
binlog-do-db=product_db_2

#屏蔽系统库同步
binlog-ignore-db=mysql
binlog-ignore-db=information_schema
binlog-ignore-db=performance_schema
# bin log日志保存天数
expire_logs_days = 30
从库增加我们的serverId和binlog日志配置：
[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8
[mysqld]
#设置3307端口
port = 3307
# 设置mysql的安装目录
basedir=D:\\KaiFaGongJu\\mysql-5.7.40-winx64-slave
# 允许最大连接数
max_connections=200
# 服务端使用的字符集默认为8比特编码的latin1字符集
character-set-server=utf8
# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB


#开启日志
log-bin = mysql-bin
#设置服务id，主从不能一样
server-id = 2
#设置需要同步的数据库
replicate_wild_do_table=store_db.%
replicate_wild_do_table=product_db_1.%
replicate_wild_do_table=product_db_2.%

#屏蔽系统库同步
replicate_wild_ignore_table=mysql.%
replicate_wild_ignore_table=information_schema.%
replicate_wild_ignore_table=performance_schema.%
重启MySQL服务，并且在主库和从库上创建一个测试库名：store_db

1：主库配置

在主库上创建一个新用户，给从库用来读取数据
# 127.0.0.1这里是从库的服务器ip

CREATE USER 'MySlave'@'127.0.0.1' IDENTIFIED BY '123456';
GRANT REPLICATION SLAVE ON *.* TO 'MySlave'@'127.0.0.1';
FLUSH PRIVILEGES;
查看Master库状态，记录二进制文件名和位置
# 二进制文件为mysql-bin.000001，位置为528


mysql>  show master status;
+------------------+----------+------------------------------------+---------------------------------------------+-------------------+
| File             | Position | Binlog_Do_DB                       | Binlog_Ignore_DB                            | Executed_Gtid_Set |
+------------------+----------+------------------------------------+---------------------------------------------+-------------------+
| mysql-bin.000001 |      528 | store_db,product_db_1,product_db_2 | mysql,information_schema,performance_schema |                   |
+------------------+----------+------------------------------------+---------------------------------------------+-------------------+
1 row in set (0.00 sec)

2：从库配置

进入从库，执行命令关联主库
mysql>  CHANGE MASTER TO MASTER_HOST='127.0.0.1',MASTER_PORT=3306,MASTER_USER='MySlave',MASTER_PASSWORD='123456',MASTER_LOG_FILE='mysql-bin.000001',MASTER_LOG_POS=528;
Query OK, 0 rows affected, 1 warning (0.72 sec)
启动salve同步进程
mysql> start slave;
Query OK, 0 rows affected (0.09 sec)
查看salve的状态
# Slave_IO_Running: Yes，Slave_SQL_Running: Yes时说明两个线程已启动，主从复制配置成功。

mysql>  show slave status\G

测试

在主数据库新建一个表，刷新从数据库，可以看到这个表。


备注：
在进行数据库主从复制前，主数据库中已有表和数据，则这部分数据不会同步，需要手动导出，并在从数据库中导入。
