文中有一处错误XSX自己发现的 master_port=3316 没指定

2、数据库安装

可以参考之前写的文章：安装MySql并修改初始密码

这里贴一下Slave数据库安装的日志

Welcome to the MySQL monitor.  Commands end with ; or \g.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

4.2 重启从数据库并设置Slave数据库

net stop MySQL2
net start MySQL2

登录从数据库并做如下设置

mysql> stop slave;  #关闭Slave
mysql> change master to master_host='192.168.1.103',master_user='javen',master_password='123456',master_log_file='mysql-bin.000001', master_log_pos= 2519;

mysql> start slave;  #开启Slave

注意：在这里指定Master的信息，master_log_file是在配置Master的时候的File选项， master_log_pos是在配置Master的Position 选项，这里要进行对应。

4.3 查看Slave配置的信息

show slave status 查看配置的信息：

mysql> show slave status \G;
