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

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.
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

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

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.
