open source load balancer

Server planning: The entire system in the RHEL5U1 server 64-bit version, by the Xen-based virtual machine, wherein the cluster management node * 2, SQL node * 2, Data node * *, Web Service node * *, the data node is made up of 2 groups, each group of two units of the form: Virtual machine mysql_mgm-1, 192.168.20.5: Cluster Management node, id=1 Virtual machine mysql_mgm-2, 192.168.20.6: Cluster Management node, id=2 Virtual machine mysql_sql-1,192.168.20.7:sql node, MySQL server

there is no need to use The other is Linux-based, open-source, free load balancing software similar to Nginx/lvs/haproxy, which is implemented at the software level, so it's very inexpensive.At present, the structure of the Web site architecture is generally more reasonable: the Web front-end uses nginx/haproxy+keepalived as the

Network troubleshooting: Consider the Server Load balancer System It may be difficult to eliminate network problems. If a Server Load balancer system is added to the network, it will pose another challenge. It may not be easy to identify whether the Server Load

performance, nor understand the current status of the server, or even the occasional situation where customer requests are concentrated on a server. 3. Reverse Proxy Server Load balancer uses a proxy server to forward requests to internal Web servers. Using this acceleration mode can obviously increase the access speed of static Web pages. Therefore, you can also consider using this technology to allow the

Reprint please explain the source: http://blog.csdn.net/cywosp/article/details/38036537 First, let's take a look at the layer chart of the TCP/IP protocol family that everyone is very familiar with: the role of each layer in the network packet transmission process is not the focus of this article, this article mainly explains how to use IP addresses at the network layer for server cluster load balancing and

Apache Load Balancer operation Apache function is actually very powerful, recently studied the next Apache reverse proxy and load balancing, reverse proxy network network export and my blog export is through the reverse proxy Apache implementation, summed up, the emphasis on load balancing configuration

"I am a novice in load balancing, the documentation is too complex and needs getting started. ”"I want to initialize a load balancer for the first time in life and need guidance. ”If you are a novice, if you first touch the load balancer, if its name is Citrix NetScaler, the

Windows Azure Platform Family of articles CatalogNote: If Azure is facing a customer that is only an enterprise customer, an enterprise customer accessing the Internet with a NAT device, because multiple clients use the same source IP address, can cause a single server to be under a lot of stress.This feature has been out for some time, the author here to do a little note.　　Readers familiar with the Azure platform know that the rules for Azure

Ningx acts as a Load balancer and is also a reverse proxy server. The configuration syntax is quite simple. It can be used to balance the backend servers by round robin, IP_hash, url_hash, weight, and other methods, it also supports backend server health check. In addition, it has advantages over LVS because it is based on Layer 7 Server Load

operating system, and real server can run on any TCP/IP-enabled operating system, including Linux, Unix (such as FreeBSD, Sun Solaris, HP UNIX, etc.), mac/ OS, Windows, and more.3.5 Open Source SoftwareThe LVS cluster software is a free software issued under the GPL (GNU public License) license, so the user can obtain the source code of the software, and can mak

Ps:nginx/lvs/haproxy is currently the most widely used three load balancing software, I have been implemented in a number of projects, reference to some information, combined with some of their own experience, summed up.The general use of load balancing is to use different technologies depending on the stage of the site's ascent. Specific application needs to be specific analysis, if it is small and medium-

policy Go to the conf directory of Apache, open the httpd. conf file, and add the following content to the end of the file: Proxypass/balancer: // proxy/# note that it ends "/"Balancermemberhttp: // 192.168.6.37: 6888/Balancermemberhttp: // 192.168.6.38: 6888/ Let's observe the above parameter "proxypass/balancer: // proxy/", where "proxypass" is the command to

with our solution, and fault-tolerant performance is not a test. Of course, there is always a solution to the problem. We introduce the concept of clustering, which I call the Group, which is the node of each library we introduce multiple machines, each of which holds the same data, and in general the load is distributed by multiple machines, and the load balancer
