Use lvs to achieve ftp Load Balancing
To make the model simple enough, only loadblance is implemented here, and
Nginx layer-4 load balancing configuration, nginx layer-4 load balancing
Configure the proxy Mysql Cluster Environment for nginx layer-4 Server Load balancer as follows: Step 1
Check whether the stream module is installed in Nginx.
The installation procedure is as follows:
Nginx implements detailed configuration of Cluster load balancing, nginx Load Balancing
In fact, the Nginx Server Load balancer function is the same as the nginx proxy function. Instead, you only need to change one proxy machine to multiple servers. Compared with lvs, Nginx
upper limit, and there is basically no consumption in memory and CPU.
2. Low configuration, which is usually a major disadvantage, but it is also a major advantage. because there are not many configurable options, you do not need to touch the server frequently except increase or decrease the server, this greatly reduces the likelihood of human error.
3. Work is stable. Because of its strong load resistance capability, high stability is also a logic.

GG has nn warehouses arranged in a circular manner along railway lines. Each Warehouse stores a different amount of goods. How to use a minimum volume of transportation can make the inventory of nn warehouses the same. When carrying goods, it can only be carried between adjacent wa
Balancing method in LVs.IP load Balancing can be used with hardware devices or software implementations. The main products of hardware equipment is F5-BIG-IP-GTM (abbreviation F5), software products are mainly LVs, HAProxy, NginX. Which LVs, Haproxy can work on the 4-7 floor, nginx work on the 7 floor. For a simple co
applications have a limit on the number of CPUs that can be used.
The server acts as a separate entity, which is a single point of failure in the solution. If only one server is responsible for passing the functionality of the component within the application, its failure can cause the application to fail.
Adding servers increases the complexity of managing and monitoring server hardware and its associated software.

Load Balancing (Balance) is one of the factors that must be considered in the design of distributed system architecture.It usually means to allocate the request/data "evenly" to multiple operation units, and the key of load balancing is "uniformity".
The uniformity here is not the 10÷2 = 5 we imagined, which is even. N

Today, the ' large server ' model has been replaced by a large number of small servers, using a variety of load balancing techniques. This is a more feasible approach that minimizes the cost of hardware.
The advantages of ' more small servers ' outweigh the past ' large server ' patterns in two ways:
1. If the server goes down, the load

A Web cluster is made up of multiple servers running the same Web application at the same time, as if it were a server, with multiple servers working together to provide more high-performance services to customers. Cluster more standard definition is: A set of independent server in the network performance of a single system, and a single system of the mode of management, this single system for customer works
Not long ago I was in charge of a well-known national manufacturing group's load balancing project. I was deeply touched by the project's application of gslb in a specific environment and learned a lot of related Load Balancing knowledge. Today, let's calm down and think about how to learn a lot through the project. du
There is a big difference between cluster, distributed and load Balancing in PHP, the following article I will give you specific to write a cluster, distributed and load-balanced between the specific differences, say not much, let us take a look at it.
