I'd like to have the possibility to accomplish a certain routine (fi. trigger a external node script or any kind of script/method whatever), when certain queries come along in MS SQL Server 2014.

Is there a way to accomplish that? (worst case - monitoring log events?)

Im used to SQL but a beginner on MS SQL Server

I have one machine (centos7) with Apache, PHP, MariaDB and Nginx, Nodejs, MongoDB installed and being used by many different domains.

I'd like to create a working mirror and can't decide between 2 options:

1. rsync static websites, server and config files + mariadb and mongodb replications
2. cluster made of 2 machines with some proxmox or other free technology (topic new for me)

I am running an app with react and node that uploads csv files via react, node then converts them to json, processes the data and finally it outputs an excel file using npm exceljs, the whole thing takes a little time on my local environment but it works well.

But when I put it on production I get a 502 error when it's processing the excel file.

There is no much information other than 502, on the ...

I am using fluentd, Elasticsearch and Grafana stack for logging and monitoring setup. I am tailing the logs(in JSON format) coming from NodeJS container/pod deployed in EKS cluster and dumping into Elasticsearch.

Problem The log format coming in stdout from node(deployed using pm2 web server) is not accurate json for example:

I’m using letsencrypt for a few sub domains one of which is chat.mydomain.com which is setup as an alias of the main domain in Apache because it uses a socket on specific port and doesn’t require a doc root.

The chat server is written in node, it runs in the background using forever and the chat code uses a socket on port 3002.

Everything works fine except on my iPhone. If I’m on the computer  ...

Just a heads up: This is the first time I try to deploy a react application on a custom built Windows server, but I’ve managed to do it successfully on Heroku and Linux (PM2), so I know that the application architecture is suppose to work correctly.

The scenario:

If you visit https://tapwar.io, it loads for so long (well, by the time I wrote this post) and it only happens when more than 60 people are connected.

Here are the further details on the app: It is a nodejs app listening on port 5000, I used Apache CentOS 7. The server is working properly if there are less traffic, I used proxy.conf like so:

A colleague is having issues getting a node web service hosted on azure to be able to access a file server on premise.

It might be a simple question but I am trying to wrap my head around server mechanics. If I have a node app o server listening to port 3000 and yet browsers by default use port 80 for http requests, how dow my request resolve on the server?

Thanks.

Since this dev is new to node, and so do i, what exactly can we do?

I have an AWS ALB that load balances requests round-robin to four servers.

Each server uses pm2 to round-robin those requests to six CPUs.

NodeJS processes (react NextJS) are running on each of those six CPUs, served by Express.js. One of the first things they do is log the incoming request. (They are not fronted by a web server like apache or nginx, it goes straight to Express.js.)

Usually every singl ...

I have a little puzzle.

I'm trying to get Ansible to deploy NodeJS to a server(s) that do not have access to download Node from the official website. Really, no access to the web (And enabling isn't an option). But I am able to send stuff to the servers from a trusted box.

Hopefully this question has an answer that's generic to Apache and Node.js, and not specific to Plesk ('cause I know how you feel about Plesk-specific questions!).

I have multiple node web servers hosted on EC2 with a Load Balancer, and some users are getting a 502 even before the request reaches the server.

I don't have the logs of those requests inside the servers, that's why I am assuming that the request never reaches the server.
