Windows服务器下MySql数据库单向主从备份详细实现步骤分享

Jun 07, 2016 pm 06:06 PM

将主服务器中的MySql数据库同步到从服务器中,使得对主服务器的操作可以即时更新到从服务器,避免主服务器因环境或者网络异常一时无法使用,达到备份效果,这篇文章整理的确实挺详细的

一、目的:将主服务器中的MySql数据库同步到从服务器中,使得对主服务器的操作可以即时更新到从服务器,避免主服务器因环境或者网络异常一时无法使用,达到备份效果。

二、环境:

主从服务器操作系统、数据库版本均相同,具体如下:
操作系统:Windows 2003 Server R2
MySql数据库版本:5.0.51b
主服务器(用A代替)IP地址:192.168.4.100
从服务器(用B代替)IP地址:192.168.4.101

三、配置过程:

1、在A创建远程访问备份账户。
在A的MySql数据库中建立一个备份账户,命令如下:
代码如下:
  mysql> GRANT REPLICATION SLAVE,RELOAD,SUPER ON *.* TO july@'192.168.4.101' IDENTIFIED BY '123456';
  mysql> Flush privileges;
  mysql> Quit;


语句解释:

第一句中*.*表示所有数据库,如果要对某个数据库备份的话,假如数据库名称为some,则要换成some.*,其中 TO july@'192.168.4.101',july为远程访问用户名,IP地址为远程访问IP,BY '123456'中123456为远程访问密码;
第二句语句执行后使得远程访问用户创建生效;

执行说明:

执行上述语句后,若要看远程访问用户是否已经创建成功,执行以下语句:
  mysql> use mysql;
  mysql> select host,user from user;
用户列表中多了一条
+------------------------------------+------------------+
|host |user        |
+------------------------------------+------------------+
|192.168.4.101 |july |
+------------------------------------+------------------+
至此,说明远程访问用户已经创建成功。
2、关闭A的MySql服务并拷贝数据到B。
关闭A的Mysql服务,将A中的数据拷贝到B中,使得A、B服务器初始数据完全相同,并且在同步备份之前禁止对服务器中进行数据库写入操作,以保证A、B服务器的初始数据完全相同。
3、修改A中my.ini配置信息
打开my.ini文件,在[mysqld]下添加以下内容(#内容为注释):
  # server-id:A服务器的ID值
  server-id=10
  #log-bin:二进制变更日志
  log-bin=c:\log/log-bin.log
4、重启A服务器。
5、关闭B服务器,对B的my.ini进行相关配置
此处需要注意:
由于设置了slave的配置信息,mysql在数据库data目录下生成master.info,所以如有要修改相关slave的配置要先删除该文件,否则修改的配置不能生效。
打开B的my.ini配置文件,在[mysqld]中添加以下内容:
  #B服务器ID值
  server-id=11
  #远程访问IP地址
  master-host=192.168.4.100
  #远程访问用户名
  master-user=july
  #远程访问用户密码
  master-password=123456
  #主服务器端口(默认为3306,此处要注意主服务器端口是否因为防火墙被禁止)
  master-port=3306
  #同步时间间隔为60秒
  master-connect-retry=60
  #设置要同步备份的数据库,此处数据库为some
  replicate-do-db=some
6、重启B服务器,到此已完成主从备份,如果有错误,可以通过mysql_error.log进行查看。

When might a full table scan be faster than using an index in MySQL? When might a full table scan be faster than using an index in MySQL? Apr 09, 2025 am 12:05 AM

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.

Explain InnoDB Full-Text Search capabilities. Explain InnoDB Full-Text Search capabilities. Apr 02, 2025 pm 06:09 PM

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

Can I install mysql on Windows 7 Can I install mysql on Windows 7 Apr 08, 2025 pm 03:21 PM

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

Difference between clustered index and non-clustered index (secondary index) in InnoDB. Difference between clustered index and non-clustered index (secondary index) in InnoDB. Apr 02, 2025 pm 06:25 PM

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.

MySQL: Simple Concepts for Easy Learning MySQL: Simple Concepts for Easy Learning Apr 10, 2025 am 09:29 AM

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

The relationship between mysql user and database The relationship between mysql user and database Apr 08, 2025 pm 07:15 PM

In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.

Can mysql and mariadb coexist Can mysql and mariadb coexist Apr 08, 2025 pm 02:27 PM

MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.

Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Apr 02, 2025 pm 07:05 PM

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.
