haproxy+keepalived high availability for load balancingFirst, the environment5 virtual machines, respectively:1 sets of test machines (192.168.2.83);2 sets of haproxy/keepalived (192.168.2.230/192.168.2.231);2 Web Servers (192.168.2.232/192.168.2.233);Note: The VIP setting is 192.168.2.228;Second, install the configuration Web ServerBecause the installation and configuration of Web server is very simple, ac

Usage Requirements: load-balanced groups can be tocat+nginx with load Balancing clusters and LVS load balancing clusters. Compared to the three population sets, the LVS performance is the best, but the building complex, NINGX upstream module support cluster, but the cluster node fault check function is not many, performance is not comparable to haproxy. Relative to achieve what kind of effect: for the Enterprise Server (WEB.FTP, etc.) can achieve load

Basic InformationWhat is HAProxy? Haproxy provides high availability, Server Load balancer, and TCP and HTTP application-based proxy. It supports Virtual Hosts and is a free, fast, and reliable solution. Haproxy is especially suitable for websites with extremely high loads, which usually require session persistence or layer-7 processing.

supports Virtual Hosts, but it is easy to configure and has a very good server health check function. When the back-end server of the proxy fails, haproxy will automatically remove the server, and then automatically add the server after the fault is recovered. The new 1.3 introduces frontend, backend, and frontend to match rules based on any HTTP request header content, and then directs the request to the relevant backend. Ii. Load Balancing using ha

Haproxy achieves load balancing and dynamic/static Separation After haprxy Server Load balancer and dynamic/static separation, haproxy is more professional in these two aspects than nginx, including session persistence, cookie guidance, and url monitoring backend, mysql Server Load balancer is not available in nginx, but it cannot be said that haprox can replace nginx, and nginx cache is not available in pr

Https configuration for haproxy LearningSome time ago, I wrote a few articles about learning haproxy. Today, we will introduce the https configuration of haproxy. We will not introduce the advantages of https. We will only introduce how to configure https and the application of https in the actual production environment. PS: All tests passed in haproxy1.5.4. The

Preface nbsp; Haproxy is a stable, high-performance, and high-availability load balancing solution, it 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 how to use its layer-4 switching and Keepali I. PrefaceHaproxy is a stable, high-performance, and high-availability server load balancer solution that supports HTTP and TC

HAproxy + Keepalive implement LDAP proxy service Because the company has a lot of self-developed systems, all of these systems are using LDAP for authentication. Currently, we have several DC controllers to share these ldap requests, the user accesses the domain name ldap.xxxx.com to connect to the ldap server. We direct the domain name to different DC servers through DNS round robin. The following problem occurs: When a DC fails, authentication may

Haproxy-1.5.x SSL Configuration The haproxy-1.4 version agent is always used, and ssl configuration is not supported, the haproxy-1.5 version is supported, so the version is updated for testing. You can use the original apache ssl Certificate file for simple processing on haproyx. Originally intended to use haproxy-1.4

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 installation or you are only interested in t

This example is shown in theThe main implementation functions are as follows:When a customer accesses www.tb.com/tb.com, Haproxy submits the website to the e-Commerce Server clusterWhen accessing bbs.tb.com, the access request is dispatched to the Forum cluster, the forum is load balanced, and when the blog.tb.com is accessed, the request is dispatched to the blogserver cluster, to achieve the load balance of the blog cluster, in addition to the above

LB load Balancing clusters are divided into two categories: LVS (four floors) and Nginx or haproxy (seven layers). LVS is ip-based, and Nginx and Haproxy are based on applications. The client accesses the Web site by accessing the Distributor's IP. The distributor forwards the request to the corresponding machine on the back-end, depending on the type of request. load Balancing cluster with static and dynam
