If you have experience in cluster, server load balancer, and dual-machine hot standby, you will be able to answer the question: I am using a mysql database web script written in php. If cluster, server load balancer, and dual-machine hot standby are implemented, is there an all-in-one solution? I mean, what I know now

timer event exceeds ngx_accept_mutex_delay in milliseconds, set the timer to ngx_accept_mutex_delay in milliseconds. This is because the current process has not grabbed the accept_mutex lock, however, the ngx_process_change method cannot wait longer than ngx_accept_mutex_delay when there is no new event. This will affect the entire load balancing mechanism */If (timer = ngx_timer_infinite | timer> ngx_accept_mutex_delay) {timer = timer ;}}}// calcula

Record Server Load balancer web Service requests based on DNS As a forum site: There are two types of data to be processed:1. structured data, such as user names and user comments, can be stored in relational databases. 2. unstructured data, such as attachments uploaded by users. Stored in the file system. Forum architecture: Use two httpd servers to serve users' access requests. Use the record of DNS for c

1. Like Apache, they are both HTTP server software and adopt Modular Design for function implementation. They all support common language interfaces. At the same time, they also support forward and reverse proxies, virtual hosts, and URL rewriting,CompressionTransmission, SSL encrypted transmission, and so on. However, in terms of execution efficiency, nginx processes faster and consumes less memory resources. In addition, nginx also supports fcgi, wh

Brief introduction: Nginx (engine x) is a lightweight Web Server, reverse proxy server, and e-mail (imap/pop3) proxy server. The Normal mode of client Access server is direct access, with nginx Server, we can deploy the same application to different servers, the access mode is as follows: This greatly improves the concurrency capability, reduces the pressure on the server and improves the performance.
