搭建MySQL集群_MySQL
前期准备:
1.mysql配置文件的获取
a. windows 找到mysql客户端的快捷方式然后 右键 -> 属性 目标中的文件路径就是配置文件的存放位置。
目标:"C:\Program Files\MySQL\MySQL Server 5.6\bin\mysql.exe" "
--defaults-file=C:\ProgramData\MySQL\MySQL Server 5.6\my.ini" "-uroot" "-p"
其中defaults-file指定的就是配置文件路径
b. linux 输入 find -name "my.cnf" 返回mysql配置文件路径
2. Mysql的启动、停止、重启
1.windows 打开任务管理器找到mysql服务 右键 -> 具体操作
b. linux 终端:
service mysqld start --启动 service mysqld stop --暂停 service mysqld restart --重启
3. Window下Mysql服务的注册及卸载
注册mysql服务: mysqld install mysql --defaults-file="C:\Program Files\mysql-5.7.12\my.cnf"
卸载mysql服务: mysqld remove mysql
1主1从服务器搭建
环境介绍:1台win10下的mysql5.6 x64服务器 1台CentOS release 6.3 (Final)下的Mysql 5.5.37 x86服务器
mysql5.5.37 作为master 5.6作为Slave
操作:
1>. 配置master的my.cnf
[mysqld] server_id =1 #(不指定的话默认是1) log-bin=master-bin
2>. 配置slave的my.cnf
[mysqld] server-id=2relay_log=slave-relay-binrelay_log_index=slave-relay-bin.index
3>. 分别重启master和slave服务
4>. 在master主机上面创建 REPLICATION SLAVE用户
create user repl_user; GRANTREPLICATION SLAVE ON *.* TO repl_user IDENTIFIED BY 'xyzzy';
5>. 在slave主机上执行
CHANGE MASTER TO MASTER_HOST='121.89.42.1', MASTER_PORT=3306, MASTER_USER='repl_user', MASTER_PASSWORD='xyzzy';
6>. 在slave主机上执行 START SLAVE
7>. 在slave主机上执行SHOW SLAVE STATUS显示
表示成功。

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

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 chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

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.

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.
