[mysqld]# 设置mysql的安装目录,即你解压缩安装包的位置basedir = F:/CodeTools/sql/mysql/mysql-5.7.30-master# 设置mysql数据库的数据的存放目录datadir = F:/CodeTools/sql/mysql/mysql-5.7.30-master/data# 设置端口号port = 3306# 允许最大连接数max_connections = 200# 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统max_connect_errors=20

[mysqld]# 设置mysql的安装目录,即你解压缩安装包的位置basedir = F:/CodeTools/sql/mysql/mysql-5.7.30-slave# 设置mysql数据库的数据的存放目录datadir = F:/CodeTools/sql/mysql/mysql-5.7.30-slave/data# 设置端口号port = 3307# 允许最大连接数max_connections = 200# 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统max_connect_errors=20explicit_defaults_for_timestamp=true
#开启二进制日志log-bin=mysql-binserver-id=101
#binlog-ignore-db=information_schema#binlog-ignore-db=performance_schema#binlog-ignore-db=mysql#与主库配置保持一致replicate-do-db=ming#replicate-ignore-db=mysqllog-slave-updatesslave-skip-errors=allslave-net-timeout=60

数据库配置同主库 具体操作看主库配置
#开启Slavemysql> stop slave; #设置连接主库信息mysql> change master to master_host='127.0.01',master_user='ming_masrer',master_password='ming_masrer',master_log_file='mysql-bin.000002', master_log_pos=1321;#开启Slavemysql> start slave;
master_log_file 是主库 File 值 master_log_pos 是主库 Position 值 在主库执行 show master status; 可获取

mysql> show slave status;
