With regard to haproxy log configuration, We separately describe that the default haproxy log is output to the system syslog, which is not very convenient to view. In order to better manage haproxy logs, we generally define them separately in the production environment. The method is as follows: First, modify the log configuration options of

Load Balancing with HaproxyFirst, the conceptHaproxy is a free and open source software written in the C language [1] that provides high availability, load balancing, and application proxies based on TCP and HTTP.Haproxy is especially useful for Web sites that are heavily loaded, and often require session-hold or seven-tier processing. The haproxy runs on the current hardware and can support tens of thousands of concurrent connections. and its operati

I. PrefaceHaproxy is a stable, high-performance, and high-availability server Load balancer solution that supports HTTP and TCP proxy backend server pools. It is widely used as an HTTP reverse proxy because it supports powerful and flexible layer-7 acl rules. This article describes in detail how to use its layer-4 switching and Keepalived to implement a Load balancer, suitable for any TCP services such as Socket, ICE, Mail, Mysql, and private communication. The system architecture diagram is as
