Article Introduction：Key Points Monitoring file integrity is essential for website management and it helps detect when files are added, modified, deleted, or corrupted accidentally or maliciously. Hashing the contents of a file is a reliable way to monitor such changes. The hash_file() function of PHP can be used to create file structure configuration files for monitoring. The hash value of each file can be stored for later comparisons to detect any changes. You can set a database table to store the hash value of a file, where file_path stores the path of the file on the server, and file_hash stores the hash value of a file. PHP's RecursiveDirectoryIterator class can be used to traverse file trees

Article Introduction：Nginx supports three common load balancing methods: round-robin, least_conn and ip_hash. 1. Round-robin distributes requests in sequence, which is suitable for scenarios with similar back-end performance, with simple configuration but no real-time load considerations; 2. Least_conn sends requests to the server with the smallest number of connections at present, suitable for services with long connections or unstable response times, and can allocate load more reasonably; 3. IP_hash allocates fixed servers according to client IP hash, used in scenarios where session consistency is required, but the server downtime affects the corresponding user. These three methods basically meet the usage needs of most open source users.
