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

Article Title: Server Load balancer technology is used to build a high-load network site. Linux is a technology channel of the IT lab in China. Including desktop applications, Linux system management, kernel research, embedded systems and open-source, and other basic categories. The rapid growth of Internet makes multimedia network servers, especially Web servers

network data processing capabilities, and improve network flexibility and availability. Server Load balancer has two meanings: first, a large amount of concurrent access or data traffic is distributed to multiple node devices for separate processing, reducing the user's waiting for response time. Second, the operation of a single heavy load is distributed to mul

systems. Distributed and business splitting solves the problem from centralization to distribution. However, each deployed independent business still has single point of failure and unified access portal. to solve single point of failure, we can adopt redundancy. Deploy the same application on multiple machines. To solve the unified access problem, we can add a server load balancer device in front of the c

Use Network address translation to achieve multi-server load balancing. Abstract: This article discusses the server load balancer technology and load allocation strategies used by distributed network servers, and implements the server load

Linux Server load balancer-load average In the previous article, we introduced how to use the w command or the uptime command to view the average Load (avaerage) of the Linux system. What is the normal status of the average Load? How should we define the stability of the sys

Today, the ' large server ' model has been replaced by a large number of small servers, using a variety of load balancing techniques.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 balancing system will stop requesting the server to go down and distrib

Original English version, Chinese versionTony TangTranslation Arrangement In the first part, I briefly described the various factors that need to be taken into account during the design of a large J2EE system with upgrading and high reliability. This article discusses Tomcat's support for cluster, Server Load balancer, fault tolerance, session replication, and other capabilities. In this section, we will se

log cannot be written to the problem that eventually causes the entire application to crash.3. Logging to logging server you can use a logging software, such as a syslog, to write all the logs to a central server. Although this method requires more configuration, he also provides the most robust solution. PHP Load Balancer Instance If you want to use load balanc

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
