[备忘]mysql Master Slave主从同步(复制)配置及常见问题
今天用到的了这块儿的内容,服务器之间做数据同步,准备两台服务器,一台做Master,一台slave。 服务器环境:Ubuntu 10.04 64位 Server; 确保两台服务器的MYSQL版本一致,需要同步的库等一致; 一、设置Master服务器: 1,编辑Mysql配置文件 vi /etc/mysql/
今天用到的了这块儿的内容,服务器之间做数据同步,准备两台服务器,一台做Master,一台slave。
服务器环境:Ubuntu 10.04 64位 Server;
确保两台服务器的MYSQL版本一致,需要同步的库等一致;
一、设置Master服务器:
1,编辑Mysql配置文件
vi /etc/mysql/my.cnf
2,打开后,在 [mysqld]加入以下信息:
[mysqld] log-bin=mysql-bin //启用二进制日志 server-id=71 //服务器唯一ID
3,重启Mysql:
/etc/init.d/mysql restart
4,登录Mysql,创建slave同步账户:
GRANT REPLICATION SLAVE ON *.* to 'backuser'@'192.168.1.190' identified by 'backuserpwd'; flush privileges;
@后面的IP为指定的备份服务器IP,安全起见只允许该IP连接。
5,查看主服务器Master状态
show master status;
记住查询到的值:
二、配置slave从服务器
前三步配置跟Master的一样:
1,编辑Mysql配置文件
vi /etc/mysql/my.cnf
2,打开后,在 [mysqld]加入以下信息:
[mysqld] log-bin=mysql-bin //启用二进制日志 server-id=72 //服务器唯一ID,这里的ID跟Master的不能相同,
3,重启Mysql:
/etc/init.d/mysql restart
4,更改slave信息:
change master to master_host='192.168.1.193',master_user='backuser',master_password='backuserpwd',master_log_file='mysql-bin.000006',master_log_pos=20555,Master_Port=3301;
上面语句中master_log_file=’mysql-bin.000006′,master_log_pos=20555为上一步记住的值,Master_Port的值默认是3306,一般可以不用跟上,修改过的就写上吧~
5,启动slave:
slave start; //停止则为stop;
6,查看slave状态:
show slave status\G;
结果中以下两条为Yes则说明成功:
Slave_IO_Running: Yes Slave_SQL_Running: Yes
接着在主服务器数据库中添加数据测试下吧~
本身挺简单的,我写得比较详细,一步一步列出来。
若无法连接数据库,切记检查配置文件中以下内容是否被注释掉,前加#:
bind-address = 127.0.0.1

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.

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.

The process of starting MySQL in Docker consists of the following steps: Pull the MySQL image to create and start the container, set the root user password, and map the port verification connection Create the database and the user grants all permissions to the database

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.

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.

The key to installing MySQL elegantly is to add the official MySQL repository. The specific steps are as follows: Download the MySQL official GPG key to prevent phishing attacks. Add MySQL repository file: rpm -Uvh https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm Update yum repository cache: yum update installation MySQL: yum install mysql-server startup MySQL service: systemctl start mysqld set up booting
