MySQL做同步实例_MySQL
多余的废话就不说了,直接开始实战.
本次试验的mysql版本都是 4.1.7-standard-log , master 端的操作系统是 redhat 9.0 , slave 端的操作系统是 redhat 7.3.
1.修改 master 端的my.cnf,增加配置参数:
[mysqld]
log-bin
server-id=1
2. 修改 slave 端的my.cnf,增加配置参数:
log-bin
master-host=master
master-user=rep
master-password=rep
master-port=3306
server-id=2
以上参数都是最基本的配置,就不多解释了,解下来势初始化数据.
1.清空 master 上的所有 binlog,如果现存的 binlog有用的话,请先备份起来;接着把 master 上的所有数据文件打包,包括ibdata那些文件.
2.类似的放假清空 slave 上的所有 binlog,将 master上的数据文件压缩包拷贝到自身的数据文件目录下.
启动master,新增一个rep用户," grant all privileges on *.* to rep@% identified by 'rep'; flush privileges; ".
启动slave,检测同步是否成功.
一般情况下,不成功的原因是slave连接上master之后定位binlog失败,这就需要将双方的binlog都设置成一致,然后stop slave; start slave; 即可.

The article discusses using MySQL's ALTER TABLE statement to modify tables, including adding/dropping columns, renaming tables/columns, and changing column data types.

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it.

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.
