MYSQL的master/slave数据同步配置_MySQL
MYSQL的master/slave数据同步配置
我的测试环境.基本上数据是瞬间同步,希望对大家有帮助
redhat 9.0
mysql3.23.57
mysql数据同步备份
A服务器: 192.168.1.2 主服务器master
B服务器: 192.168.1.3 副服务器slave
A服务器设置
#mysql –u root –p
mysql>GRANT FILE ON *.* TO backup@192.168.1.3 IDENTIFIED BY ‘1234’;
mysql>\exit
上面是Master开放一个账号backup密码1234给IP:192.168.1.3有档案处理的权限
mysqladmin –u root –p shutdown
备份Master所有数据库..通常都用tar指令.
#tar –cvf /tmp/mysql.tar /var/lib/mysql
注意:tar的时候,MySQL是要在stop情况下
在A机器上修改/etc/my.cnf
在[mysqld]区段内加入参数
log-bin
server-id=1
sql-bin-update-same
binlog-do-db=vbb
重启A服务器mysql
此时因为有加入log-bin参数,因此开始有index产生了,在/var/lib/mysql目录下有.index档案纪录数据库的异动log.
B服务器设置
设定/etc/my.cnf
在[mysqld]区段加入
master-host=192.168.1.2
master-user=backup
master-password=1234
master-port=3306
server-id=2
master-connect-retry=60 预设重试间隔60秒
replicate-do-db=vbb 告诉slave只做vbb数据库的更新
log-slave-updates
将A上的mysql.tar copy到B上
用ftp传B的/tmp
9.解压缩
#cd /var/lib/
状况测试
1.A跟B网络及服务都正常情况下,由A端变化数据后,到B端浏览数据,检视是否有进行replication?!
2.模拟B当机,或是B不一定需要一直跟A有连接.
将由A端变化数据后,到B端浏览数据,B点应该是没有数据变化的
#tar xvf /tmp/mysql-snapshot.tar
#chown –R mysql:mysql mysql
1重启B服务器的mysql
这时在/var/lib/mysql目录会出现master.info,此档案纪录了Master MySQL server的信息.

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.

The MySQL learning path includes basic knowledge, core concepts, usage examples, and optimization techniques. 1) Understand basic concepts such as tables, rows, columns, and SQL queries. 2) Learn the definition, working principles and advantages of MySQL. 3) Master basic CRUD operations and advanced usage, such as indexes and stored procedures. 4) Familiar with common error debugging and performance optimization suggestions, such as rational use of indexes and optimization queries. Through these steps, you will have a full grasp of the use and optimization of MySQL.

MySQL's real-world applications include basic database design and complex query optimization. 1) Basic usage: used to store and manage user data, such as inserting, querying, updating and deleting user information. 2) Advanced usage: Handle complex business logic, such as order and inventory management of e-commerce platforms. 3) Performance optimization: Improve performance by rationally using indexes, partition tables and query caches.

SQL commands in MySQL can be divided into categories such as DDL, DML, DQL, DCL, etc., and are used to create, modify, delete databases and tables, insert, update, delete data, and perform complex query operations. 1. Basic usage includes CREATETABLE creation table, INSERTINTO insert data, and SELECT query data. 2. Advanced usage involves JOIN for table joins, subqueries and GROUPBY for data aggregation. 3. Common errors such as syntax errors, data type mismatch and permission problems can be debugged through syntax checking, data type conversion and permission management. 4. Performance optimization suggestions include using indexes, avoiding full table scanning, optimizing JOIN operations and using transactions to ensure data consistency.

InnoDB achieves atomicity through undolog, consistency and isolation through locking mechanism and MVCC, and persistence through redolog. 1) Atomicity: Use undolog to record the original data to ensure that the transaction can be rolled back. 2) Consistency: Ensure the data consistency through row-level locking and MVCC. 3) Isolation: Supports multiple isolation levels, and REPEATABLEREAD is used by default. 4) Persistence: Use redolog to record modifications to ensure that data is saved for a long time.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.

InnoDB effectively prevents phantom reading through Next-KeyLocking mechanism. 1) Next-KeyLocking combines row lock and gap lock to lock records and their gaps to prevent new records from being inserted. 2) In practical applications, by optimizing query and adjusting isolation levels, lock competition can be reduced and concurrency performance can be improved.
