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
Iis + nginx load balancing and iisnginx Load Balancing
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
Rotten mud: TCP application for learning haproxy with high load balancing, and load balancing haproxy

In the previous articles, we introduced the configuration parameters of haproxy, And the configuration examples are all http pro
the number of VIPs will be more.Nginx can be used as the LVS node machine, one can use Nginx function, the second is the performance of Nginx can be used. Of course, this level can also directly use the function of Squid,squid is weaker than Nginx, performance is also inferior to nginx.Nginx can also be used as a middle-tier agent, this level nginx basically no opponent, the only one can shake Nginx only lighttpd, but lighttpd at present has not been able to do nginx full function, configuratio

Use lvs to achieve ftp load balancing and lvsftp Load Balancing
Operating System: CentOS6.5 _ x64

Use lvs to achieve ftp Load Balancing
To make the model simple enough, only loadblance is implemented here, and
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 server goes down or fails to work, Keepalived will detect it and remove the
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
application, the data transmission volume is big, the network interface burden weighs heavily. ), the Equalization Strategy (algorithm) used is different. So the equilibrium strategy (algorithm) also has a variety of forms, generalized load balancing can be set up a special gateway, load balancer, but also through a number of special software and protocols to ac
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.
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 through Nginx as load balancer, unable

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
or avoiding the bottleneck of unbalanced network load distribution and long response time of data traffic congestion. For different Server Load balancer modes, Layer 2, Layer 3, Layer 4, and Layer 7 Server Load balancer of OSI reference models have corresponding Server Load balancer policies. =^The advantages and disa

3.1 rotation method:
Rotation algorithms are the simplest and easiest way to implement all scheduling algorithms. In a task queue, each member (node) in the queue has the same status. The rotation method simply rotates and selects members in the group. In the load balancing environment, the balancer sends new requests to the next node in the node queue in turn. In this continuous and cyclical
the original round robin algorithm, added a program for collecting dynamic weights and fed back it to the Load balancer's scheduling system in real time. Practice has proved that the use of dynamic balancing has improved the overall throughput of the cluster system, especially when the performance of each node in the cluster is different and the network service
balancer, but also through a number of proprietary software and protocols to achieve. In the OSI seven layer protocol model, the second (data link layer), third (network layer), fourth (transport layer), layer seventh (application layer) have corresponding load Balancing strategy (algorithm), the principle of load balancing
load balancing is the specific implementation of the Cluster Job Scheduling System. Because the job unit it processes is a network connection under the TCP/IP protocol, you can use a centralized basic scheduling algorithm for network connections. Considering the possibility of Cluster load imbalance, the weights of service nodes are dynamically obtained and the
thrown load balancing in as a feat Ure.
Round Robin: Round Robin passes each new connection request to the next server on line, eventually distributing C Onnections evenly across the array of machines being load balanced. Round
