I know what server load balancer and high concurrency should be used to solve this problem, but I don't know how to do it even though I have no experience in the concept of server load balancer and high concurrency, I searched for nginx to achieve load balancing and high con

1 overviewIn order to guarantee the stable operation of the bastion host-instruction channel, it is necessary to implement the load balance of instruction channel, and study to determine the use of LVS software.LVS is the abbreviation for Linux virtual server, that is, the Linux server, the official site is: www.linuxvirtualserver.org2 LVS ArchitectureLVS set up server cluster to achieve load balancing has

Recently, using Apache as a load balancer for a cluster, according to the relevant configuration, after adjusting the relevant content, the Apache httpd.conf file is adjusted. Add the following content:After adding such as content, the original normal Apache can not start!Looking at Apache's backend log error.log, we found the following:[Tue Dec 09 10:34:51 2014] [Notice] parent:received Restart Signal--res

Haproxy + Apache for Linux Server Load balancer Software Haproxy provides high availability, Server Load balancer, and reverse proxy Based on TCP and HTTP applications, especially for websites with extremely high loads that usually require session persistence or layer-7 processing.

: This article mainly introduces the Nginx + IIS + Web front-end (SpringMVC)-server load balancer (1). If you are interested in PHP tutorials, refer to it. Introduction When developing a large Web project, if our web is published on the IIS of a server, when a large number of requests are sent to the IIS service, the computer will crash easily. So we thought, why don't we put our services on multiple compu

Example of an nginx load balancer configuration. The configuration examples for load balancing are as follows:Http{upstreamserver{server192.168.10.100:80 weight=3max_fails=3fail_timeout=25s;server 192.168.10.101:80weight=1max_fails=3fail_timeout=25s;server 192.168.10.102:80weight=4max_fails=3fail_timeout=25s; server192.168.10.103:80weight=2max_fails=3fail_timeout

Server cluster is our kind of large-scale millions IP operations personnel will operate, today's small also to everyone over an nginx load Balancing configuration cluster method, online to find a few articles, found it is not difficult.Nginx Load Balancer One,1. Do not install in the source code in the same directory, make will be error. code is

: This article describes how to use Nginx server load balancer to build a high-performance. NETweb application 2. if you are interested in PHP tutorials, refer to it. In this article, we use Nginx server load balancer to build high performance. in NETweb Application 1, we have a preliminary understanding of Nginx. next

The previous article written the Nginx load balancer, this article realizes the high Availability (HA). The overall design of the system is to use Nginx to do load balancing, if there is an nginx single-machine failure, the whole system will not function properly. For the high-availability requirements of system architecture design, we need to solve the requireme

Introduction to Linux virtual servers Linux Virtual Server (LVS) is a high-availability Server Load balancer cluster system. The system can provide

: This article mainly introduces several methods for nginx server load balancer to process session sharing. For more information about PHP tutorials, see. 1) use cookie instead of sessionBy changing the session into a cookie, you can avoid some drawbacks of the session. in a previously read J2EE book, it also indicates that the session cannot be used in the cluster system, otherwise, it will be difficult to

: This article describes how to set up static file separation for NginxTomcat server load balancer. if you are interested in PHP tutorials, refer to it. This article mainly explains how to use Nginx as the front-end web server and tomcat as the backend application server. all Internet requests are forwarded from nginx to the intranet tomcat for processing, that is, nginx Reverse proxy requests to tomcat, or

Lvs-nat model: Similar to Dnat, but supports multi-target forwarding, which is multi-objective DnatIt is forwarded by modifying the destination address of the request message to a certain RS rip selected by the scheduling algorithm.Architectural Features:(1) RS should use a private address, that is, RIP should be a private address, each RS gateway must point to the dip(2) The request message and the response message are forwarded through the Director; in high-

For Web application cluster learning, I started from tomcat5.5. Below are some of my practical operations and experiences.
