Recently, HAproxy + keepalived + mysql was used to test the high-availability Linux system cluster.HAProxy is a free proxy software that provides high availability, load balancing, and TCP (Layer 4) and HTTP (Layer 7) applications, with HAProxy, you can quickly and reliably provide Proxy solutions based on TCP and HTTP applications.Keepalived is mainly used for h

Hproxy provides high availability, load balancing, and reverse proxies based on TCP and HTTP applications, especially for those web sites that are heavily loaded, which typically require session hold or seven-tier processing. Haproxy runs on the current hardware, fully supports tens of thousands of concurrent connections, and its operating mode makes it easy and secure to integrate into the architecture, while protecting your Web server from being exp

Description: The following references the contents of the sixth chapter of "Building a highly available Linux server" Fuqin.It is relatively simple to build a high-availability environment for load balancing, mainly to understand the principles. This article describes the pros and cons of three load balancers so that they can be used in real-world production applications by demand.At present, the online environment in the application of more load bala

Three major software load balancer comparisons (LVS, Nginx, HAproxy)(Information from the network, made part of the supplementary instructions)LVS:1. Strong anti-load capability, high performance, can reach F5 60%, low memory and CPU resource consumption2. Work in the Network 4 layer, through the VRRP protocol (for Proxy only), the specific traffic is handled by the Linux kernel, so there is no traffic gene

Comparison and summary of Linux Server LVS, Nginx, and HAProxy load balancers LVS features: 1. Strong anti-load capability. IP Server Load balancer technology is used only for distribution. Therefore, LVS does not generate much traffic; 2. good stability and reliability, and perfect Hot Standby solution (for example, LVS + Keepalived) 3. A wide range of applications, allowing Load Balancing for all applicat

The configuration of HAProxy is divided into five parts. Of course, these components are not mandatory and can be selected as needed. Global: The parameter is process-level, usually related to the Operating System (OS. These parameters are generally set only once. If the configuration is correct, you do not need to modify defaults again: to configure the default parameter, which HAProxy Configuration The
