Failed to start The nginx HTTP and reverse proxy server issue

First time I'm stalling nginx server in my fedora 24. I'm using apache server for development. For onlyoffice integration I have lớn install nginx server. I installed nginx server by using this command dnf install nginx

Before starting nginx server I stopped apache and disabled it also lượt thích below.

systemctl stop httpd
systemctl disable httpd

If I start the nginx server sudo service nginx start I'm getting below error.

Redirecting lớn /bin/systemctl start  nginx.service
Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.

So I ran the systemctl status nginx.service command lớn know issue detail, I got below output in my terminal.

[root@localhost ~]# systemctl -l status nginx.service
