When I check what process is listening on port 3000, I get node. I kill this process, but it still doesn't solve the issue. Does anyone know what is the problem here?
It means your port is already in use. Try killing port with following command
sudo kill -9 $(sudo lsof -t -i:3000)
if that not works try following
sudo lsof -i tcp:3000 // this will return some PIDs
sudo kill -9 [your pid to remove]
Then run pm2 start command again

My server is located on client premise.
I'm facing an issue, in that my service(node js) is not able to connect with redis.
If I'm checking the status of redis it's running fine.
Loaded: loaded (/lib/systemd/system/redis-server.service; enabled; vendor preset: enabled)
Active: active (running) since Wed 2023-02-15 14:16:34 EAT; 18h ago
Docs: http://redis.io/documentation,
man:redis-server(1)
Main PID: 3085148 (redis-server)
Status: "Ready to accept connections"
Tasks: 5 (limit: 19104)
Memory: 8.2M
CGroup: /system.slice/redis-server.service
I'm able to connect with the service manually from one server providing host and port.
But the issue is when my service is trying to connect so it's failing.
So can anyone help me in suggesting what could be a possible reason for the same?

Try using redis-server as the hostname and not 127.0.0.1.
I'm trying to run a very simple docker-compose.yml, but am getting a "ReferenceError: server is not defined" from index.js in the client container.

Here's the code:

client.set('visits', 0);
app.get('/', (req,res) => {
client.get('visits', (err,visits) => {

client.set('visits', parseInt(visits) + 1);

It doesn't find "redis-server", but according to the udemy course, it should find it because that's how it's identified in the composer.
What's the problem?
"redis-server" should be a string, and denoted by quotes:
const client = redis.createClient({
host: 'redis-server',
port: 6379
});
I use docker to run redis on AWS EC2 and I use kue to connect to it at my node server.
But it shows error like below.
How could I fix this? I use redis-cli to ping to IP and GUI tool to connect redis are woring fine.

I was using the following instructions to install and configure StatsD on a Graphite server:
https://www.digitalocean.com/community/tutorials/how-to-configure-statsd-to-collect-arbitrary-stats-for-graphite-on-ubuntu-14-04
Now that I have a server with StatsD running, I do not see the metrics being logged under /var/log/statsd/statsd.log when I am testing sending them from the command line. Here is what I see:
29 Oct 02:30:39 - server is up
29 Oct 02:47:49 - reading config file: /etc/statsd/localConfig.js
29 Oct 02:47:49 - server is up
29 Oct 14:16:45 - reading config file: /etc/statsd/localConfig.js
29 Oct 14:16:45 - server is up
29 Oct 15:36:47 - reading config file: /etc/statsd/localConfig.js
29 Oct 15:36:47 - DEBUG: Loading server: ./servers/udp
29 Oct 15:36:47 - server is up
29 Oct 15:36:47 - DEBUG: Loading backend: ./backends/graphite
29 Oct 15:36:47 - DEBUG: numStats: 3
The log stays at the last entry of 'numStats: 3', even though I keep entering different metrics at the command line.
Here are a sample of the metrics I entered:
echo "sample.gauge:14|g" | nc -u -w0 127.0.0.1 8125
echo "sample.gauge:10|g" | nc -u -w0 127.0.0.1 8125
echo "sample.count:1|c" | nc -u -w0 127.0.0.1 8125
echo "sample.set:50|s" | nc -u -w0 127.0.0.1 8125
Of interest, I see this under /var/log/statsd/stderr.log:
events.js:72
throw er; // Unhandled 'error' event
^

Here is what my localConfig.js file looks like:
{
graphitePort: 2003
, graphiteHost: "localhost"
, port: 8125
, graphite: {
legacyNamespace: false
},
debug: true,
dumpMessages: true
}
Would anybody be able to shed some light as to where the problem lies?
Thanks!
There is a management interface available by default on port 8126: https://github.com/etsy/statsd/blob/master/docs/admin_interface.md
You likely have another service listening on that port in the same system.
Try this:
# localConfig.js
{
graphitePort: 2003
, graphiteHost: "localhost"
, port: 8125
, mgmt_port: 8127
, graphite: {
legacyNamespace: false
},
debug: true,
dumpMessages: true
}
See https://github.com/etsy/statsd/blob/master/exampleConfig.js#L28
