Nginx works with IIS to achieve simple load balancing and nginxiis Load BalancingDeploy nginx in linux. This article mainly introduces how to implement load balancing with iis after nginx is deployed. java is not used, but the principle should be the same.1. IIS deploys the
Use lvs to achieve ftp load balancing and lvsftp Load Balancing
Operating System: CentOS6.5 _ x64
Problem description
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
In windows, ARR of IIS is used to achieve site load balancing and arr load balancing.1) Purpose:
Access localhost: 18066
Load the following two ports
Localhost: 18098
Localhost: 18099
2) means:
1. Use nginx
2. Use the ARR (Application Request Routing) of iis)
3) use the ARR
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
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 t

Brief description: nginx introduction Baidu.
Objective: To distribute user requests to servers to relieve pressure. Nginx evenly forwards requests from listening ports to servers deployed on the website.
1. Install nginx on windows 1. Download nginx http://nginx.o
Configure Keepalived on the cluster to achieve load balancing and keepalived Load BalancingIntroduction:
Keepalived is a high-availability service solution based on VRRP protocol, which can be used to avoid IP spof. The purpose of Keepalived is to check the status of the server. If a web
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
After configuring Nginx, when accessing Tomcat, Tomcat displays such as:
From this state can be seen, guess is CSS and JS these files are not loaded.
In addition, access to the pages deployed on the Tomcat project is the same, with different nginx accesses to the project under Tomcat such as:
Through Nginx as a proxy server, access to the page is like this:
These conditions are obviously due to the server
the execution time of a single task, while clustering increases efficiency by increasing the number of tasks executed per unit of time. Example: For example, Sina, the number of people who visit, he can do a cluster, the front of a balanced server, the next few servers to complete the same business, if there is business access, the response server to see which server
, memory capacity, disk and so on, to achieve the improvement of server processing capacity, can not meet the large-scale Distributed System (website), large traffic, high concurrency, massive data problems. Therefore, a scale-out approach is required to accommodate the processing power of large Web services by adding machines. For example: A machine can not be satisfied, then add two or more machines, the joint burden of access pressure. This is the
The size of the Internet doubles every one hundred days. The customer wants to achieve uninterrupted availability within 7 days and fast system response time, rather than repeatedly seeing a site "server too busy" and frequent system faults.
As the business volume increases, the traffic volume and data traffic increase rapidly, the processing capability and computing strength of each core part of the network also increase, making it impossible for a
With the development of information construction in various industries, people put forward higher requirements for the processing ability and high availability of the network server.

Window| Strategy | With the development of information construction in various industries, people put forward higher requirements for the processing ability and high availability of the network server. Especially in highly information-based enterprises, the key network services have become an important part of enterprise generation process, interruption of service means the interruption of production and the loss of opportunity.
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
Issues to consider Before proposing a specific load balancing solution, we need to start by explaining some of the things we need to consider when designing a load balancing system. The first thing to say is to pay attention to the high availability and scalability of the loa

1. DNS load balancing method
The RR-DNS (round-robin Domain Name System) takes turns by: In a DNS server,You can configure the same name for multiple IP addresses. When the client queries this name, it will get an address when parsing this name. Therefore, for the same name, different clients will get differ
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:
