After multiple tomcat servers are used for load balancing, the tomcat port is not open to the public, so the tomcat server Load balancer can be accessed precisely.
Background:
Use Nginx and two Tomcat servers to achieve load balancing, disable tomcat ports (8080 and 8090) in the firewall, and open only port 80 to the
configuration.After changing the configuration, we need to restart the Nginx server, or reload (only let it reload the configuration), so that the changes take effect:Service Nginx ReloadBelow we create a test code that tests whether the access is normal "Note: Must be created in the machine where the PHP-FPM is located":cd/opt/wwwvi index. phpWrite the following code:PHP Echo ' Hello! I am server-b ';Then use the browser of other computers to access the ip:http://192.168.168.131 of the machine
At present, the development of business volume in Enterprise Networks, campus networks, and wide area networks, such as the Internet, exceeds the most optimistic estimates in the past. The Internet boom is surging and new applications are emerging one after another, even if the network is built according to the optimal configuration at that time, it will soon feel overwhelmed. Especially for the core parts of each network, the large data traffic and computing strength make it impossible for a si
Ningx acts as a Load balancer and is also a reverse proxy server. The configuration syntax is quite simple. It can be used to balance the backend servers by round robin, IP_hash, url_hash, weight, and other methods, it also supports backend server health check. In addition, it has advantages over LVS because it is based on Layer 7 Server Load
request is sent, and then send the request to the server.
Client-Based Load Balancing features:
Implemented by the internal program of the client, without the need for additional hardware and software investment of the Server Load balancer.
The program must solve the problem of Service Server unavailability, And th

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. NAT (Network address mapping):The NAT mode can support any operating system, as well as private networks, and requires only one Internet IP address, but t

Summary: For a large website, Server Load balancer is an eternal topic. With the rapid development of hardware technology, more and more Server Load balancer hardware devices are emerging, such as F5 big-IP, Citrix NetScaler, and radware, however, the high price is often prohibitive, So
Cluster) A cluster is a loosely coupled multi-processor system composed of a group of independent computer systems. It communicates with each other through a network. Applications can transmit messages through the network shared memory to implement distributed computers.Load Balance) Server Load balancer is a dynamic balancing technology. It uses some tools to analyze data packets in real time, master the
There are many Server Load balancer solutions. The haproxy + keepalived solution is used here.
