applications. Local Load Balancing refers to load balancing for local Server clusters, and global Load Balancing refers to load balancing between server clusters with different network structures in different geographic locations. Local Server Load

scalability will be more powerful, and the client can be completely unaffected.In addition, the client detects the balancer and allows the customer to find the network area with the fastest response speed.As for the disadvantages, the opposite is the advantage of solution 1. Since the advantages of solution 1 are not an advantage, this disadvantage is naturally not a disadvantage. Can be ignored. Load Bala

addresses. Therefore, the client that queries this name will get an address, in this way, different customers can access different servers to achieve load balancing. DNS Server Load balancer is a simple and effective method, but it cannot distinguish between servers or reflect the current running status of servers. When using DNS Server

, you can also consider suchTechnology: Use a proxy server to evenly forward requests to multiple servers to achieve load balancing. 3. address translation gateway Server Load balancer supports the address translation gateway of Server Load balancer. You can map an external

Defined:LVS is a shorthand for Linux virtual server, that is, a virtualized server cluster system.Structure:In general, the LVS cluster uses a three-tier structure, the main component of which is: A, Load Scheduler (load balancer), it is the entire cluster to the outside of the front-end machine, responsible for sending the customer's request to a set of servers

Apache self-built Server Load balancer cluster function recorded by: xuanfei I have searched the internet and found that it seems that I seldom talk about the functions of the mod_proxy module. So today I am going to learn how to buy it. Let's talk about the versions earlier than apache2.2, I have more information about the internet. I 'd like to say a few simple words below :) The following example uses t

Nginx Server Load balancer configuration instance details Server Load balancer is one of the things we need to do for a large-traffic website. Next I will introduce how to configure Server Load balancer on the Nginx server. I hope

specified url to detect the status of the backend server.3. similar to LVS, HAProxy itself is only a server load balancer software. in terms of efficiency alone, HAProxy has a better load balancing speed than Nginx, it is superior to Nginx in concurrent processing.4. HAProxy supports TCP server load

5. Installation Configuration keepalivedKeepalived is running on the LVS, its main function is to realize the real machine fault isolation and load balancer between the failure switch Failover.lvs combined with keepalived, the implementation of 3-layer, 4-layer, 5/7-layer switching functions. The following is the second use of LVS, lvs+keepalived. The installation and verification of Ipvsadm is the same as

class BSD license. Despite being a beta version, Nginx is well known for its stability, rich feature sets, sample configuration files, and low system resource consumption. First, the configuration is very simple and powerful. It's time to see each other. Let's take a look at how to write the configuration file worker_processes 1; events {worker_connections 1024;} http {upstream myproject {# specify multiple source servers, ip: Port, port 80 can be wr

log cannot be written to the problem that eventually causes the entire application to crash.3. Logging to logging server you can use a logging software, such as a syslog, to write all the logs to a central server. Although this method requires more configuration, he also provides the most robust solution. PHP Load Balancer Instance If you want to use load balanc

In addition, DNS, as a request scheduler, cannot take the load capacity of each server, the current Load Status of the server, and other factors into account when the request is balanced, real

One, LVS three kinds of packet forwarding methodLVS provides three packet forwarding methods: NAT (Network address mapping), IP tunneling (IP tunneling), direct Routing (straight route)Different forwarding mode determines the network structure of different cluster, and the following three kinds of forwarding methods are respectively started:1.

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

the same server, which further improves the efficiency of the backend cache server. Nginx does not support url_hash. To use this scheduling algorithm, you must install the nginx hash package. In the HTTP upstream module, you can use the server command to specify the IP address and port of the backend server, and set the status of each backend server in the Server Load
