I've got a production server with **Apache 2.4.38** on **Debian 10** and sometimes the web server doesn't function properly and doesn't immediately send a response to the HTTP requests it gets (All virtual hosts requests on it are completely unresponsive (no matter what they reverse proxy to)). After a restart it immediately fixes itself or after being like this a while (seconds or even minutes) and starts sending A LOT of HTTP responses all of a sudden.

CPU and RAM usage seem to be fine, so it's definitely not that. I don't know what exactly is going on and why it's doing this. I've also changed mpm_event.conf settings, they currently are set to this:

StartServers                     2
        ServerLimit 100
        MinSpareThreads          25
        MaxSpareThreads          75
        ThreadLimit                      128
        ThreadsPerChild          25
        MaxRequestWorkers         400
        MaxConnectionsPerChild   5000

There are some errors I've seen in the Apache error log though:

What settings can I change that would fix this issue?

https://unix.stackexchange.com/q/126745/762527 follow up to this. If I want to server a file directory from another server, what would be the process apart from rsync/scp?

Let's say I use Apache, and that I am in /var/www/html/. I do: mkfifo test.tar tar cvf - ~/test/* > test.tar & In a browser, when trying to download http://localhost/test.tar I get: ERR_EMPTY_RESPONSE (didn’t send any data) Is there a specific parameter of mkfifo that would the pipe look really like a regular file? Here the problems seems to come from the fact the file is a named pipe. In my real example, I might use different webservers (not Apache), like [CivetWeb](https://github.com/civetweb/civetweb) , but first I want to analyze if it works with Apache (that I use the most).

I'm building a solution with multiple modules. Each module is a ReactJS app, and I trying config nginx to publish it on the same domain. For examples: - http://application-domain/**auth** - http://application-domain/**admin** - http://application-domain/**dashboard** - http://application-domain/**sales** My public directory for nginx stay like this:

/var/www
├── /auth
├── /admin
├── /dashboard
└── /sales

Where auth, admin, dashboard, and sales are subfolders for each project. My nginx server conf: server { listen 9000 default_server; listen [::]:9000 default_server; server_name localhost; index index.html; location / { root /var/www/auth; } location /admin { root /var/www; } location /dashboard { root /var/www; } location /sales { root /var/www; } } Each project's subfolder has the similar structure like this The problem is when access http://application-domain/admin , for example, the application try to load the static files on root instead subfolder project GET http://localhost:9000/static/js/main.6314dcaa.js net::ERR_ABORTED the correct would be get files on **admin** sub folder like this: GET http://localhost:9000/admin/static/js/main.6314dcaa.js What's the better approach to correct nginx configuration for this?

I installed caddy with "sudo apt install caddy" and have everything setup and working, but I also want to run caddy automatically from boot. When I use

sudo systemctl enable caddy

and reboot, I get a 403 error from my website. To fix this I kill caddy and use

cd /home/user/Desktop/websida

then

sudo caddy run

, then it's fixed, no errors but I have to do this every time I boot, hence why I want it to run as a service but in another directory: /home/user/Desktop/websida

All the methods I found on the Internet involved using a .jsp page and a web browser. I have Linux servers with no GUI desktops. I do not want to use the web browser on a desktop to view a .jsp file on every web browser. I want to find out from the backend. This way I can use a script to find out on every server. How do I find the version of JQuery that is installed on a Linux web server?

I'm unfamiliar with Debian (obviously), so I downloaded the live ISO thinking it might help me. From the live GUI, I doubled click on the install icon on the desktop and proceeded - it gave me an install with GNOME and a bunch of other software that has no business being on a web server. Generally. So the first part of my question is, can I install the base/non-GUI version from the Live disc? If so, how? If not, can someone point me to the correct download for the amd64 bit version? I want what would be the Debian equivalent to Ubuntu Server - a simple, bare-bones, non-GUI OS. I prefer to install my HTTP server as well - I'm not sure if I'll be going with Apache or Nginx or handling HTTP requests myself in node.js...

I have Lighttpd web server on my Ubuntu server. It works as expected. But now I want that it shows files in folders. I follow the instructions, but it doesn't work.

If I remove the index.html file, I get "403 Forbidden". Any idea what can be wrong?

Every nginx config guide I find is about setting up the server for, say, example.com. But I don't have a domain name, and I want to set up a local DNS, something like localhost in Windows with Apache that comes with XAMPP. I want to create two ports, which is I believe server blocks in nginx. One of the ports is for api, one of the ports is for the frontend. I have created two files: /etc/nginx/conf.d/chubak.conf: server { listen 85; server_name chubak.com; access_log /srv/logs/vue.access.log; error_log /srv/logs/vue.error.log; gzip_static on; # root /srv/default; root /var/www/chubak.com/html; index index.html; location / { add_header 'Access-Control-Allow-Origin' '*'; try_files $uri $uri/ /index.html; } And /etc/nginx/conf.d/api.chubak.conf: server { listen 180; server_name api.chubak.com; access_log /var/www/api.chubak.com/logs/api.access.log; error_log /var/www/api.chubak.com/logs/api.error.log; root /var/www/api.chubak.com/html; index index.php index.html; client_max_body_size 128M; location / { try_files $uri $uri/ /index.php?_url=$uri&$args; } location ~ \.php$ { include /etc/nginx/fastcgi.conf; fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_param PATH_INFO $fastcgi_path_info; fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; try_files $uri =404; fastcgi_pass unix:/var/run/php/php7.2-fpm.sock; fastcgi_read_timeout 600; fastcgi_intercept_errors on; gzip off; fastcgi_index index.php; } And I've created index.html files in the /var/www/site/html folder, but I don't know how to access them. As I said, the tutorials always assume that you have a domain name pointed to your server.

I'm trying to install Wordpress using OpenLiteSpeed webserver. Wordpress is installed in /usr/local/lsws/Liveragi/html/{wordpress files}. When I access the page using HTTP the page has a "404 Not Found" error and with HTTPS the page is throwing a "403 Forbidden" error. I have PHP latest version installed and the web panel works well. If I put an .html file it works but if it is PHP, I get "403 Forbidden". Hope someone has the solution to this. Thanks. PS: I'm using Ubuntu Server latest version

I have a website using the Python http.server module and it was working great. Earlier this day I wanted 2 users to work on the same files (HTML, CSS, JS) so I set the chmod tag to 777. The problem is that the CSS content now only updates when starting a new browser session, whereas the HTML content updates every time I refresh the page without any issues. I have tried: - Clearing the browser cache using Ctrl+F5/Shift+F5 - Changing the ownership of the files to a group containing the editor users (using chgrp) - Removing caching in Nginx - Removing caching in Cloudflare If you need any additional info, I'd be happy to provide it.

I have looked at various resolve.conf questions on here and other documentation but they're talking about DNS as an external thing, which doesn't help me distinguish in this case. - I have a server. The server has some sort of DNS issues. - The server runs Linux (CentOS 7.9) and has 2 IP addresses that point to it. - The server has a /etc/resolve.conf which contains two *other* IP addresses. Should these *other* IP in resolve.conf be the 2 that point to the server or should they be 2 "stranger" IPs pointing to upstream? THanks

I have a server box I use to host various web applications and game servers for friends. I recently connected to it to check how it was running, and discovered a program "Opera" trying to use over 3000% of my CPU according to top. I tried to kill it with pkill Opera and pkill then used killall to do the same, which worked initially, but the Opera program came back within a minute or so. I checked through all of my system services and cron jobs and can't find any mention of "Opera" anywhere, and trying to run the command manually ("Opera", not "opera" like the browser) just prompts me to install the opera browser from snap. top only informed me that opera was somehow located at ./Opera. I eventually tracked down the executable by following the symlink in /proc/ and found it in /var/tmp inside a "Documents" folder with some other odd files (a config.json, and several hidden files with strange names and no extensions) the picture I've included does not have the Opera file, as I deleted it. /var/tmp/Documents folder without the Opera executable" class="img-fluid rounded" style="max-width: 100%; height: auto; margin: 10px 0;" loading="lazy"> Deleting the executable seems to have fixed the problem, but I still have no idea what it was caused by or what the Opera executable is, what it was doing, and why it was executing from the /var/tmp folder. I mainly want to know if this is a known virus or trojen, and whether I should purge the user it's executing from. Editing this because I forgot to add my system info. My operating system is Ubuntu 22.04.4 LTS and I use bash as my kernel. my kernel version is Linux 5.15.0-116-generic Any help is appreciated, thanks!

I created an angular app in CentOs7 and was able to open it in a web browser in my CentOs7 VM using http://localhost:4200/. I need to be able to access it my Windows 10 VM, but when I tried changing the IP, it still worked in Cent but gave me an error saying port 4200 is already in use. It doesn't work in Windows with either address. How do I configure this so it's accessible in my Windows VM?

I want my Apache web server running on a Livebox (home router appliance running Linux) to be accessible from the Internet (WAN). I installed and configured the application noip2 on my Ubuntu PC. When I ping my hostname, it redirects me to my WAN ip, which is what I wanted. But I cannot access my Apache web server. I tried this: - Disabling the iptables firewall configuration or the firewall of my Sagem modem. - Port forwarding on sagem modem (NAT). - Configuration of Apache. What else can I try? How can I make my web server accessible from the WAN side?

After applying this configuration, I'm repeatedly getting the following error:

The WebSocket connection keeps closing unexpectedly and immediately reopening, which creates a constant loop. - Is there something wrong or missing in my Nginx WebSocket configuration? - How can I fix the WebSocket disconnection issue when running Focalboard in a subdirectory?

I have a script which generates a daily report which I want to serve to the so called general public. The problem is I don't want to add to my headaches maintance of a HTTP server (e.g. Apache) with all the configurations and security implications. Is there a dead simple solution for serving one small HTML page without the effort of configuring a full blown HTTP server?

I have a VPS instance running FreeBSD. I started a simple web server on port 80. When I am ssh'd into the server, I can reach the server:

$ curl 
hello

However, when I try to connect on my own device:

$ curl http://
curl: (28) Failed to connect to  port 80 after 8710 ms: Couldn't connect to server

I have searched on how to fix it, but have thusfar not been able to solve it. Here's some information that might be useful: - Running ifconfig vtnet0 returns inet - This IP address is the same address as my VPS provides shows in the server management tool - My firewall (using pf) (pf.conf):

I am using react pdf 9.1.0 to show the pdf in browser, now I want to make the react pdf support the partial download. The server side was using openresty, I read the pdf.js manual that told me to make the server side add partial download. how to make openresty support the pdf partial download? I have added the configuration: location /tex/static/proj { alias /data/k8s/reddwarf-pro/texhub-server-service/project/; add_header Accept-Ranges bytes; autoindex off; } how to make the openresty handle the pdf range request?
