Course Introduction：To clean MySQL binlog files, you should use the PURGEBINARYLOGS command or set the automatic expiration time, and files cannot be deleted directly. 1. Use the PURGE command to clean old logs by file name or time. Before execution, you need to confirm that the slave library no longer uses the relevant logs; 2. Check the current log status and slave library location through SHOWMASTERSTATUS and SHOWSLAVESTATUS to ensure the security of the cleaning range; 3. It is recommended to set the binlog_expire_logs_seconds parameter to achieve automatic cleaning, which is suitable for long-term operation environments; 4. Deleting files directly will cause serious problems such as master-slave synchronization failure and inconsistent log information, and must be avoided.

Configure the server-id and relay-log of the slave server, use the CHANGEMASTER command to connect to the master library and start the replication thread; 4. Check for common problems, such as network, permissions, data consistency and self-increase conflicts, and monitor replication delays.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
