This article provides a detailed introduction to achieving dual-machine hot standby with Keepalived, building internal network service load balancing with HAProxy, and resolving NIC soft interrupt issues for network performance optimization. Through real-world cases and detailed configuration explanations, this article helps readers understand the core principles and practical applications of these technologies.</p>/en/archives/08-bash-dev-query/Wed, 05 Jul 2017 00:00:00 +0000/en/archives/08-bash-dev-query/<h2 id="introduction">Introduction</h2> <p>In message system operations, queue backlog is a common and tricky problem. Especially during malicious attacks or system anomalies, the delivery queue may accumulate a large number of messages, severely impacting normal system operation. Traditional single-process processing is not only inefficient but may also cause problems to worsen due to delayed handling.</p> <p>This article shares a set of advanced Bash programming techniques based on the producer-consumer pattern. Through core technologies including multi-process concurrency, pipe communication, and efficient awk parsing, we achieve fast and effective handling of message queue backlog issues. This solution has been validated in multiple production environments, capable of improving processing efficiency several times over while ensuring system stability.</p>
