}Cache is controlled through http headers. helloworld
Let’s try it out. Let’s write helloworld.js
var http = require('http');
http.createserver(function (request, response) {
response.writehead(200, {'content-type': 'text/plain'});
response.end('hello world\n');
}).listen(61337);
console.log('server running at http://127.0.0.1:61337/'); and then open it with the node helloworld.js command, so that it runs locally Even if the machine's nodejs program is started, it occupies port 8000, which can be modified by yourself. At this point, make sure that the settings in nginx's vhost.conf should be: server {
listen 80;
server_name jb51.net.jb51.net;
location / {
proxy_pass http://127.0.0.1:61337;
}
}Set the website domain name, then set the port to 80, and finally set proxy_pass to http:/ /127.0.0.1:61337, pass all requests from jb51.net:80 to the nodejs program. Restart nginx, access the domain name, and you can see helloworld.
Although it is true that node.js itself can be used as a server, for example, just set port 80 in welcome.js.
But one machine runs multiple websites, and other websites use other servers. When port 80 is already occupied, it can be processed by proxy to other ports.

After installing Nginx, the configuration file path and initial settings
May 16, 2025 pm 10:54 PM
Understanding Nginx's configuration file path and initial settings is very important because it is the first step in optimizing and managing a web server. 1) The configuration file path is usually /etc/nginx/nginx.conf. The syntax can be found and tested using the nginx-t command. 2) The initial settings include global settings (such as user, worker_processes) and HTTP settings (such as include, log_format). These settings allow customization and extension according to requirements. Incorrect configuration may lead to performance issues and security vulnerabilities.
How to limit user resources in Linux? How to configure ulimit?
May 29, 2025 pm 11:09 PM
Linux system restricts user resources through the ulimit command to prevent excessive use of resources. 1.ulimit is a built-in shell command that can limit the number of file descriptors (-n), memory size (-v), thread count (-u), etc., which are divided into soft limit (current effective value) and hard limit (maximum upper limit). 2. Use the ulimit command directly for temporary modification, such as ulimit-n2048, but it is only valid for the current session. 3. For permanent effect, you need to modify /etc/security/limits.conf and PAM configuration files, and add sessionrequiredpam_limits.so. 4. The systemd service needs to set Lim in the unit file
What are the Debian Nginx configuration skills?
May 29, 2025 pm 11:06 PM
When configuring Nginx on Debian system, the following are some practical tips: The basic structure of the configuration file global settings: Define behavioral parameters that affect the entire Nginx service, such as the number of worker threads and the permissions of running users. Event handling part: Deciding how Nginx deals with network connections is a key configuration for improving performance. HTTP service part: contains a large number of settings related to HTTP service, and can embed multiple servers and location blocks. Core configuration options worker_connections: Define the maximum number of connections that each worker thread can handle, usually set to 1024. multi_accept: Activate the multi-connection reception mode and enhance the ability of concurrent processing. s
