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)

    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

    I am running NGINX Plus but it doesn’t matter in this case.

    sudo systemctl stop apache2
sudo systemctl start nginx

    should work since looks like the port is in use (with apache probably)

    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
