How to check whether nginx is started in Linux system

The first method: View the process list and filter Each application running in Linux will generate a process, then we can determine whether the Nginx process is started by checking whether it exists. Use ps-ef to list the processes and then filter through grep. For example: ps-ef|grepnginx can see whether the Nginx process exists. The second method: directly check the process idps-Cnginx-opid. This method of directly returning the pid is more suitable for use in conjunction with other programs. For example, execute this command in a shell/python script to get the pid, and then determine whether Nginx is based on the pid. start up. This method is recommended. The third method: use nets

Nginx basic knowledge introduction example analysis

nginx is a high-performance http and reverse proxy server known for its high stability, rich feature set, sample configuration files, and low system resource consumption. nginx features handle static files, index files and automatic indexing; open file descriptor buffering. Cacheless reverse proxy acceleration, simple load balancing and fault tolerance. fastcgi, simple load balancing and fault tolerance. Modular structure. Including filters such as gzipping, byteranges, chunkedresponses, and ssi-filter. If multiple SSIs present in a single page are processed by fastcgi or other proxy servers, this processing can run in parallel without waiting for each other.

How to configure Nginx to support websocket

1. Understanding of wss and nginx proxy wss: 1. The wss protocol is actually websocket+SSL, which means adding an SSL layer to the websocket protocol, similar to https (http+SSL). 2. Use nginx to proxy wss [Communication principle and process] The client initiates a wss connection and connects to nginx. Nginx converts the wss protocol data into ws protocol data and forwards it to the websocket protocol port of Workerman. After receiving the data, Workerman does business logic processing and Workerman gives it to the customer. When the client sends a message, the process is the opposite. The data is converted into wss protocol through nginx/ and then sent to the client. 2.

How to reverse proxy Nginx to Tomcat server

In actual production, tomcat servers are generally not used alone in projects. Nginx performs better in responding to static resources. In addition, since nginx is a server specifically used for reverse proxy, it is easy to forward Java requests to the backend. The client is handed over to the tomcat container for processing, and it is used to process static resources. In nginx, a server{} block is often used to configure a relatively large project. Generally, it is all the configurations of a domain name. There are usually multiple configurations in a server block. location to define multiple request rules, such as domain name and root directory configuration, static resource support, phpfastcgi request, url rewriting, error page configuration and other configurations, so

How to configure a Python web project using Nginx and uWSGI

Common deployment methods for web projects based on python are: fcgi: Use spawn-fcgi or the tools that come with the framework to generate listening processes for each project, and then interact with the http service. wsgi: Use the mod_wsgi module of the http service to run each project. But there is also uwsgi, which neither uses the wsgi protocol nor the fcgi protocol. Instead, it creates its own uwsgi protocol. According to the author, this protocol is about 10 times as fast as the fcgi protocol. The main features of uwsgi are as follows: Ultra-fast performance. Low memory usage (measured to be about half of mod_wsgi of apache2). Multi-app management. Detailed log

How to solve nginx panic group problem

1. Solution When each worker process is created, it will call the ngx_worker_process_init() method to initialize the current worker process. There is a very important step in this process, that is, each worker process will call the epoll_create() method to create a unique process for itself. Some epoll handles. For each port that needs to be monitored, there is a file descriptor corresponding to it, and the worker process only adds the file descriptor to the epoll handle of the current process through the epoll_ctl() method and listens to the accept event. Triggered by the client's connection establishment event to handle the event. from

What is Socket segmentation in Nginx server

The 1.9.1 release of nginx introduced a new feature: allowing the use of the so_reuseport socket option, which is available in new versions of many operating systems, including dragonflybsd and Linux (kernel version 3.9 and later). This socket option allows multiple sockets to listen on the same IP and port combination. The kernel is able to load balance incoming connections across these sockets. (For nginxplus customers, this feature will appear in version 7, which will be released by the end of the year) The so_reuseport option has many potential practical applications. Other services can also use it to simply implement rolling upgrades during execution (nginx already supports rolling upgrades). right

Nginx configuration file example analysis

Common functions of nginx 1. http proxy, reverse proxy: As one of the most commonly used functions of web servers, especially reverse proxy. Here I will give you two pictures to explain the positive agent and the reactive agent. You can read the information for the specific details. When nginx is used as a reverse proxy, it provides stable performance and can provide forwarding functions with flexible configuration. nginx can adopt different forwarding strategies based on different regular matching, such as going to the file server at the end of the image file, and going to the web server for dynamic pages. As long as you have no problem writing regular rules and have corresponding server solutions, you can do whatever you want. of play. And nginx performs error page jump, exception judgment, etc. on the returned results. If the distributed server stores
