以下文章主要是对MySQL 复制设置的介绍 ,我们大家都知道MySQL 复制设置在实际运用中经常出现的,如果你是MySQL 复制设置这一技术的热捧着,那么下面的文章对于你而言一定很有意义。
1、停止MySQL服务
2、MySQL 复制所有文件,包括数据文件
3、master的my.ini基本不需要修改,缺省已经配置成master方式:
log-bin=MySQL-bin
binlog_format=mixed
server-id = 1
4、slave的my.ini需要修改如下:
去掉3中的master配置,添加如下内容:
server-id = 2
master-host = localhost
master-user = replication
master-password = replication
master-port = 3306
replicate-do-db=需要MySQL 复制的数据库
master-connect-retry=10
修改端口为3307等,
添加replication用户用于进行MySQL 复制。
5、重启master、slave数据库。
6、如果master设置成功,可以通过show master status;命令看到如下信息:
<ol class="dp-xml"> <li class="alt"><span><span>+------------------+----------+--------------+------------------+ </span></span></li> <li><span>| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | </span></li> <li class="alt"><span>+------------------+----------+--------------+------------------+ </span></li> <li> <span>| </span>MySQL<span>-bin.000007 | 39259 | | | </span> </li> <li class="alt"><span>+------------------+----------+--------------+------------------+ </span></li> <li><span>1 row in set (0.00 sec) </span></li> </ol>
7、如果全部设置成功,在slave中运行show slave status;命令,可以看到相应的配置参数,说明master、slave都设置正常。
8、如果想通过CHANGE MASTER TO命令修改相应的参数,需要首先用stop slave;命令停止slave,修改成功后再运行start slave;启动slave服务。
注意:开始直接停止MySQL服务最方便,不需要进行锁表的操作。以上的相关内容就是对MySQL 复制设置的介绍,望你能有所收获。

You can open phpMyAdmin through the following steps: 1. Log in to the website control panel; 2. Find and click the phpMyAdmin icon; 3. Enter MySQL credentials; 4. Click "Login".

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.

Redis uses a single threaded architecture to provide high performance, simplicity, and consistency. It utilizes I/O multiplexing, event loops, non-blocking I/O, and shared memory to improve concurrency, but with limitations of concurrency limitations, single point of failure, and unsuitable for write-intensive workloads.

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.

Effective monitoring of Redis databases is critical to maintaining optimal performance, identifying potential bottlenecks, and ensuring overall system reliability. Redis Exporter Service is a powerful utility designed to monitor Redis databases using Prometheus. This tutorial will guide you through the complete setup and configuration of Redis Exporter Service, ensuring you seamlessly build monitoring solutions. By studying this tutorial, you will achieve fully operational monitoring settings

The methods for viewing SQL database errors are: 1. View error messages directly; 2. Use SHOW ERRORS and SHOW WARNINGS commands; 3. Access the error log; 4. Use error codes to find the cause of the error; 5. Check the database connection and query syntax; 6. Use debugging tools.

Apache connects to a database requires the following steps: Install the database driver. Configure the web.xml file to create a connection pool. Create a JDBC data source and specify the connection settings. Use the JDBC API to access the database from Java code, including getting connections, creating statements, binding parameters, executing queries or updates, and processing results.
