the virtual IP, the backend server gateway does not point to the load balancer, and Lvs-tun requires the backend service to support IPIP unpacking.　　Some operating systems are not supported.　　2) from the throughput point of view, lvs-dr highest, Lvs-nat lowest.　　3) In terms of ease of configuration, Lvs-nat is minimal, lvs-dr and Lvs-tun are more complex. It is recommended to use LVS-DR mode in the applica

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

Preface: The company has developed a website. The estimated maximum number of online users is 30 thousand, and the maximum number of concurrent users is 100. Whether or not the developed website can withstand this pressure and how to ensure that the load of the website is no problem, after research, it is decided as follows: (1) Server Load balancer and cluster t

. All servers and test clients use the vmwarevm for simulation and the CentOS 7 The VS kernel supports ipvs and installs ipvsadm to control and write lvs rule tools. The two RS servers balance the request load for the httpd server. Note; 1) The client can use a Windows browser and cache the results after the meeting. Therefore, it is more intuitive to use the curl command on CentOS to request http protocol

: Each request from the network is distributed to each internal server in turn, starting from 1 to n and then restarting. Example: This balancing algorithm is suitable for all servers in the server group with the same hardware and software configurations and Relatively Balanced average service requests; -Least connection algorithm (least connection ): Note: Each time the client requests the service to stay on the server, there may be a big diff

In redhat9.0, lvs sets up the Server Load balancer server-Linux Enterprise Application-Linux server application information. The following is a detailed description. Install the required components: Standard internal package linux-2.4.20-tar.gz, with the software matching the internal package s-1.0.09.tar.gz Linux Kernel requires patching, hidden-2.4.20per10-1.di

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

: This article mainly introduces how to build the Nginx + Tomcat + Memcached server load balancer cluster service. For more information about PHP tutorials, see. Reprinted please indicate the source: http://blog.csdn.net/l1028386804/article/details/48289765 Operating system: CentOS6.5 This document describes how to set up an Nginx + Tomcat + Memcached server load

1. Story ReviewIn my previous blog, I built two Web servers and then built an nginx load balancer server on the front end to distribute the requests to two different servers (http://blog.51cto.com/superpcm/2095324). The previous test is not a problem because the test program is a static web site that is purely static and does not change. Later I set up on both the web to build a WordPress service, and then

1. network load balancing working principle Network Load Balancing uses a cluster of two or more host computers working together to provide high availability and scalability for servers. An Internet client uses an IP address or a group of addresses to access the cluster. Clients cannot distinguish clusters from single servers. Server ApplicationsProgramIt does not indicate that they are running on the clus

At present, the development of business volume in Enterprise Networks, campus networks, and wide area networks, such as the Internet, exceeds the most optimistic estimates in the past. The Internet boom is surging and new applications are emerging one after another, even if the network is built according to the optimal configuration at that time, it will soon feel overwhelmed. Especially for the core parts of each network, the large data traffic and computing strength make it impossible for a si

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

request is sent, and then send the request to the server. Client-Based Load Balancing features: Implemented by the internal program of the client, without the need for additional hardware and software investment of the Server Load balancer. The program must solve the problem of Service Server unavailability, And th

: Worker. loadbalancer. type = lb Each type has different actions, which will be described below. 3. set Worker attributes: After defining a worker, you also need to provide the attributes of each worker. the following methods are used to define these attributes: Worker .. = 3-1 ajp12 type Worker attribute :. When ajp12 type worker is working, the ajpv12 protocol based on TCP/IP socket is forwarded to the Tomcat worker "out-of-process. The attributes of ajp12 worker are as follows: Ho
