Haproxy is a free and open source software written in C that provides high availability, load balancing, and TCP and HTTP-based application proxies that can run on most major Linux operating systems.This experiment uses three servers to build a Web cluster, haproxy as a dispatch server, two Nginx servers as node servers.Experimental environmentHost | System | IP
This article is sponsored by Ilanniweb, starting in Slime Line the worldTo get more articles, you can follow my ilanniweb.Yesterday introduced Haproxy's mobile phone matching rules, today to introduce the next Haproxy and Nginx, Zabbix integration. Next I will describe in detail the integration of Haproxy and Nginx di
Comparison of haproxy lvs nginx Load Balancing
For the software that implements load balancing, let's take a look at it in detail. In terms of performance and stability, LVS is the best, basically reaching 60% of the performance of F5 hardware equipment, and other 10% are a little difficult.
However, the configuration is also the most troublesome because of LVS, and the Health Check requires configuring Ldi
These days I compare nginx and Haproxy, and come to a surprising result.First, some background information is presented. For a long time, we bengler the Nginx as the main Web server for our project, just as we did under mongrel as a proxy for rails. Nginx is a very good small open source software, it occupies a small s

But because of the LVS bull, configuration is the most troublesome, and health testing needs to be configured Ldirector, other haproxy and nginx themselv
HAProxy, Nginx configuration HTTP/2 Complete GuideBased on the recent controversy over HTTP/2 and its advantages, it's time to upgrade the underlying architecture. This article will show you how to install and configure Haproxy and Ngnix (using SSL terminals). To streamline the process, I recommend that you be ready to use the Docker image.If you want to skip the
Install Nginx (as HTTP server) and Haproxy (reverse proxy) in the test environment, and configure Haproxy log output to/var/log/haproxy.log, take note.It should be explained that this is only a basic installation, configuration method, and does not involve specific usage in a production environment.First, install Nginx1. Preparation environmentYum install-y gcc #

first, the experimental explanation
Haproxy load Balancing scheduling at the front end for dynamic and static separation at the backend
Static resource server is Nginx
Dynamic content uses Nginxtomcat as an app server, integrated into a single machine, two
Use two memcache servers for high-availability session caching, enabling app server downtime for sessions without interruption
The above combination uses
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

participate in the loadThe larger the weight defaults to 1.weight, the greater the weight of the load.Max_fails: The number of allowed requests failed defaults to 1. Returns the error Proxy_next_upstream module definition when the maximum number of times is exceededFail_timeout:max_fails after a failure, the time of the pause.Backup: All other non-backup machines request backup machines when down or busy. So this machine will be the lightest pressure.
Third,
In order to compare the effects of hproxy and nginx load Balancing, respectively on the test machine (the following experiments are tested on a single machine, that is, the load machine and the back end of the machine are on a computer) do the two load balancing environment, and their respective capture packet analysis.The following are the results of the packet capture analysis under these two load balancing environments:1)
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 balancer hardware has F5 big-IP, software has Lvs
NOTE: For the following content, refer to Chapter 6 of "building a high-availability Linux Server" of fuqin liquor. It is relatively simple to set up a high-availability server Load balancer environment, mainly to understand the principle. This article describes the advantages and disadvantages of the three load balancers so that they can be selected as needed in actual production applications. Currently, there are F5 BIG-IP, LVS, nginx and
