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

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

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

one file. The benefits are simple, possibly as long as there are few configurations. However, as the number of servers increases, it becomes very difficult to monitor log files on each server. 2. Logging to a share this method is still available for each server, but they are stored on a central file server through a sharing mechanism, which makes monitoring logs easier. The problem with this scenario is that if the file server is unavailable, a simple log cannot be written to the problem that e

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

: This article mainly introduces apache and nginx server load balancer configurations. For more information about PHP Tutorial, see. I. apache server load balancer is actually very powerful in operating apache. Recently, I have studied apache reverse proxy and server

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

To solve the unified access problem, we can add a server load balancer device in front of the cluster to achieve traffic distribution. Load Balance (SLB) balances the
