Unexpected result of Nginx

I've a server with 2 services on it. Software are Ubuntu20.04 OS, Nginx and certbot.
So, then I check nginx status:
~$ sudo systemctl status nginx.service
● nginx.service - A high performance web server and a reverse proxy server
Loaded: loaded (/lib/systemd/system/nginx.service; disabled; vendor preset: enabled)
Active: failed (Result: exit-code) since Mon 2021-12-13 10:48:55 CET; 35min ago
Docs: man:nginx(8)
....
des. 13 10:48:55 u nginx[248435]: nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
des. 13 10:48:55 u nginx[248435]: nginx: [emerg] still could not bind()
des. 13 10:48:55 u systemd[1]: nginx.service: Control process exited, code=exited, status=1/FAILURE
des. 13 10:48:55 u systemd[1]: nginx.service: Failed with result 'exit-code'.
des. 13 10:48:55 u systemd[1]: Failed to start A high performance web server and a reverse proxy server.
and checking of configuration:
~$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
But at the same time both services are up and working as they should. If I ask about nginxs' processes, i've next
~$ sudo ps -ax | grep nginx
245336 ? S 0:00 nginx: worker process
245337 ? S 0:00 nginx: worker process
245338 ? S 0:00 nginx: worker process
250704 pts/7 S+ 0:00 grep --color=auto nginx
and check one of them (it doesn't matter which one)
~$ sudo systemctl status 245336
● snap.certbot.certbot.***********.scope
Loaded: loaded (/run/systemd/transient/snap.certbot.certbot.***********.scope; transien>
Transient: yes
Active: active (running) since Mon 2021-12-13 09:39:30 CET; 1h 35min ago
I can't imagine what happens and why it works in this way. Before this problem, I updated certbot and deleted a few certifates (they were expired and unused).
Who can explain me how it's work? And why are the services up?

Is there a way to resolve an issue with nginx status Active: inactive (dead) problem in CENTOS

This is what it brings when you check nginx status
[root#ttproxyapp conf.d]# service nginx status
Redirecting to /bin/systemctl status nginx.service
● nginx.service - nginx - high performance web server
Loaded: loaded (/usr/lib/systemd/system/nginx.service; disabled; vendor preset: disabled)
Active: inactive (dead)

sudo systemctl stop apache2
sudo systemctl start nginx
should work since looks like the port is in use (with apache probably)

It realy looks like your NGINX ins't running. nginx -s reload is just working if there is a running instance and therfore a PID-file.
Please check the result of the following command.
[root#localhost conf.d]# sudo ps -elf | grep nginx
Should be something like
1 S root 88262 1 0 80 0 - 13143 sigsus 23:47 ? 00:00:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
5 S nginx 88263 88262 0 80 0 - 13257 ep_pol 23:47 ? 00:00:00 nginx: worker process
0 R root 88265 69227 0 80 0 - 28178 - 23:47 pts/1 00:00:00 grep --color=auto nginx
You need at least! the master process and the worker process! If there is no process start your instance by typing
sudo /bin/systemctl start nginx.service OR sudo service nginx start
Check your processlist after running the command.
After you have started the NGINX service there should be PID-file located at
/var/run/nginx.pid and sudo systemctl status nginx.service should printout something like
[root#localhost conf.d]# systemctl status nginx.service

Mar 14 23:47:13 localhost.localdomain systemd[1]: Started NGINX Plus - high performance web server.
I am running NGINX Plus but it doesn't matter in this case.

there is maybe an apache server running. you must stop that apache server order run the Nginx server.
sudo systemctl stop apache2
sudo systemctl start nginx

I re-installed Elasticsearch and Kibana but still getting that restart every 14 seconds. I was able to resolve this issue by removing "noexec" from /var; got the solution from https://discuss.elastic.co/t/kibana-server-is-not-ready-yet-throw-er-unhandled-error-event/175879/7
I actually debugged the startup of Kibana and this was the log I got during the stop to start:

which led me to search for "kibana: Error: spawn /var/lib/kibana/headless_shell-linux/headless_shell EACCES" that directed me to the solution URL.
Thanks to Kaldayr for the solution.

One other potential place to look for info on Kibana shutting down and restarting is /var/log/messages
grep kibana /var/log/messages

Shiny-server installation: Server not responding on port 3838

I installed the shiny-server on a Ubuntu 16.04.1 and according to the console output it is active and running:
systemctl status shiny-server
● shiny-server.service - ShinyServer
Loaded: loaded (/etc/systemd/system/shiny-server.service; enabled; vendor preset: enabled)
Active: active (running) since Wed 2016-08-24 18:17:09 CEST; 15h ago

└─13179 /opt/shiny-server/ext/node/bin/shiny-server /opt/shiny-server/lib/main.js --pidfi
lines 1-11/11 (END)
Then I opened the port 3838 as stated in the installation guide:
netstat -ntlp | grep LISTEN
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)

Howevever if I try to access my server over the port 3838 in a browser, I don't get any response from the server and the site stays blank and eventually times out.
Any ideas what I might be missing?

Apparently there was some problem with the port 3838 on my server. Although the console output above states that it is open and listed as "LISTEN", it still didn't work. When I changed the default port for my shiny-server in the configuration file (/etc/shiny-server/shiny-server.conf) to 80, it suddently worked:
# Define a top-level server which will listen on a port
server {
# Instruct this server to listen on port 3838
listen 80;

How to disable FTP port (Debian)?

I am newbie in Debian. I have open FTP port (21) on Debian 6 (http server of the system is Nginx). How I can stop or disable the port via service or somehow yet? The command /etc/init.d/proftpd stop is not working, it shows in console bash: /etc/init.d/proftpd: No such file or directory because proftpd is absent.

Inputing this command netstat -tnlp, you can find which process is running on port 21.
Then you can some work by youself.

If you are to lazy to stop the service from running you can write an iptables rule
sbin/iptables -A INPUT -p tcp --destination-port {PORT-NUMBER-HERE} -j DROP

Start by checking if your port is listening
sudo ss -tulnp | grep LISTEN
Netid State Recv-Q Send-Q Local Address:Port Peer Address:Port Process

So, you see in port 21 you have service vsftpd listening.
You can check the status:
sudo service vsftpd status
● vsftpd.service - vsftpd FTP server
Loaded: loaded (/lib/systemd/system/vsftpd.service; enabled; vendor preset: enabled)
Active: active (running) since Tue 2022-07-19 09:42:45 EDT; 2 months 15 days ago
Main PID: 1230 (vsftpd)

Memory: 972.0K
CPU: 7ms
CGroup: /system.slice/vsftpd.service
└─1230 /usr/sbin/vsftpd /etc/vsftpd.conf
Now, you can block the port with the firewall (for example you can use ufw), or stop the service
$ sudo service vsftpd stop
$ sudo service vsftpd status
● vsftpd.service - vsftpd FTP server
Loaded: loaded (/lib/systemd/system/vsftpd.service; enabled; vendor preset: enabled)
Active: inactive (dead) since Mon 2022-10-03 10:55:50 EDT; 9s ago

Oct 03 10:55:50 Tuxy systemd[1]: Stopping vsftpd FTP server...
Oct 03 10:55:50 Tuxy systemd[1]: vsftpd.service: Succeeded.
Oct 03 10:55:50 Tuxy systemd[1]: Stopped vsftpd FTP server.
So, in summary. Install ufw. Unblock only ports you are going to use (ssh, etc). Start only the services you are going to use. (sudo service *** start/stop)
good luck
