redis reads configuration file

The path where Redis reads the configuration file is located at /etc/redis/redis.conf or /usr/local/etc/redis/redis.conf. It reads the configuration file and parses it line by line, storing the configuration options in an internal data structure. Common configuration options include ports, bound IP addresses, maximum number of client connections, client idle timeout, number of databases, and settings for saving data to disk. After modifying the configuration file, you need to restart the Redis server to apply the changes.
