Mysql主库服务器重启造成从库同步失败(Got fatal error 1236 fr
某一台vps最近隔一周左右就会被意外重启一次,悲催的是这台vps上正好搭着Mysql的主库,这台机器重启后会造成从库的数据库同步时候出现「Got fatal error 1236 from master when reading data from binary log: 'Client requested master to start replicatio
某一台vps最近隔一周左右就会被意外重启一次,悲催的是这台vps上正好搭着Mysql的主库,这台机器重启后会造成从库的数据库同步时候出现「Got fatal error 1236 from master when reading data from binary log: 'Client requested master to start replication from impossible position'」的错误。
这时候的状态是:在从库上执行SHOW SLAVE STATUS;
时候会出现Slave_IO_Running: No
的提示。并能找到
解决办法(适用于lnmp 0.9版本):
- 登录主库服务器
- 执行/usr/local/mysql/bin/mysqlbinlog /usr/local/mysql/var/mysql-bin.000023>test.txt
- less test.txt
- 找到最近的一条position id,参考下图:
- 从库服务器mysql执行STOP SLAVE;
- CHANGE MASTER TO MASTERHOST='主库ip',MASTERUSER='同步用户',MASTERPASSWORD='同步密码',MASTERLOGFILE='mysql-bin.000023',MASTERLOG_POS=130216;
- SLAVE START;
- 这时候再看SHOW SLAVE STATUS;就会看到已经可以正常同步了

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.

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".

Create a database using Navicat Premium: Connect to the database server and enter the connection parameters. Right-click on the server and select Create Database. Enter the name of the new database and the specified character set and collation. Connect to the new database and create the table in the Object Browser. Right-click on the table and select Insert Data to insert the data.

You can create a new MySQL connection in Navicat by following the steps: Open the application and select New Connection (Ctrl N). Select "MySQL" as the connection type. Enter the hostname/IP address, port, username, and password. (Optional) Configure advanced options. Save the connection and enter the connection name.

MySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.

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.

Recovering deleted rows directly from the database is usually impossible unless there is a backup or transaction rollback mechanism. Key point: Transaction rollback: Execute ROLLBACK before the transaction is committed to recover data. Backup: Regular backup of the database can be used to quickly restore data. Database snapshot: You can create a read-only copy of the database and restore the data after the data is deleted accidentally. Use DELETE statement with caution: Check the conditions carefully to avoid accidentally deleting data. Use the WHERE clause: explicitly specify the data to be deleted. Use the test environment: Test before performing a DELETE operation.
