Build the Tomcat cluster, the front-end of a nginx, to the back of the Apache server, the Apache is responsible for the back-end of the Tomcat server for resource scheduling, such a model than directly with Nginx back to the back-end host, the Tomcat server will receive less pressure, The service will be more stable, and such a model is tested in practice. If Nginx is dispatched directly to the back-end Tom

1. Introduction:Nginx is a Web server that can proxy http, HTTPS, SMTP, IMPS, POP3 protocol connections, as well as a load balancer, and HTTP caching.2. Features: Nginx is a performance-oriented design of the HTTP server, compared to Apache, lighttpd, with less memory, high stability and other advantages. Nginx does not adopt the design model of each client thread, but uses the asynchronous log

the page size and loading time, that is, requests are allocated based on the response time of the backend server, and requests are prioritized for short response time. Nginx does not support fair. to use this scheduling algorithm, you must download the Nginx upstream_fair module. Url_hash. This method distributes requests based on the hash results of the access url so that each url is directed to the same backend server, which further improves the efficiency of the backend

We used to do the Lync reverse proxy we used to use TMG, but TMG has too many problems, such as only installed on the Server2008 server, and Microsoft has no subsequent development, we can now use IIS arr to implement the reverse proxy function, he compared to TMG does not need to deploy the server alone, Just find a s

After lunch break to work, colleague said test site access interface appeared in the Too request request Header Or Cookie Large hint, thought fortunately is the test server problem, the impact is not small, but also hurriedly on the server to Test view, Open Nginx and UGWSI log and configuration, found that the back-end service logging is normal, and the test site access log has more than 700 m (only run two or three days without a few visits, a few m is the normal phenomenon), Direct access to

load balancing can be very convenient scale-out server cluster, to achieve the overall concurrency of the cluster, and improve the ability to stress.2, usually the reverse proxy server with the local cache function, through the cache of static resources, effectively reduce the pressure on the back-end server, thereby

In this case, There is an application running ASP, which is relatively earthy and still uses a local *. mdb database. In this way, it is impossible to run the plug-in Apache: ASP in a Linux environment. It is also a pretty bad ASPProgram, Even HTML templates are not stored in separate directories and are directly mixed with *. asp. Fortunately, this world has nginx, which is the best Optimization for such things. If IIS is used to process both A

In order to save money, the company needs to be distributed in different machine sites are migrated to a machine, and now different machines are running different Web services, part Nginx, part of Apache, because of the more rewrite rules involved, in order to save changes in Kung Fu, After the plan to migrate the site still use the original Web services, but the same machine 80 port can only be assigned to a Web service use, so the plan Nginx use 80,

Because the project needs to implement the function of a domain name agentLike what: The code is as follows Copy Code A.com/a.html=>b.com/b.html That is, using the a.com agent of the use of B.Com Web site request, after a friend introduction with Apache reverse agent can achieve its purpose, the man tried, really cool. It is also extremely convenient to configure. (No
