This worked for me  First  go to cd  etc nginx and make the changes in nginx conf and make the default port to listen from 80 to any of your choice 85 or something  Then use this command to bind that port type for nginx to use it  semanage port -a -t PORT TYPE -p tcp 85 where PORT TYPE is one of the following  http cache port t  http port t  jboss management port t  jboss messaging port t  ntop port t  puppet port t  Then run  sudo systemctl start nginx   sudo systemctl status nginx  you should see active status    sudo systemctl enable nginx

Try to run the following two commands   sudo fuser -k 80 tcp  sudo fuser -k 443 tcp  Then execute   sudo service nginx restart  If that worked  your hosting provider might be installing Apache on your server by default during a fresh install  so keep reading for a more permenant fix  If that didn t work  keep reading to identify the issue     Run nginx -t and if it doesn t return anything  I would verify Nginx error log  By default  it should be located in  var log nginx error log    You can open it with any text editor  sudo nano  var log nginx error log  Can you find something suspicious there   The second log you can check is the following  sudo nano  var log syslog  When I had this issue  it was because my hosting provider was automatically installing Apache during a clean install  It was blocking port 80    When I executed sudo nano  var log nginx error log I got the following as the error log   2018 08 04 06 17 33  emerg  634 0  bind   to 0 0 0 0 80 failed  98  Address already in use  2018 08 04 06 17 33  emerg  634 0  bind   to      80 failed  98  Address already in use  2018 08 04 06 17 33  emerg  634 0  bind   to 0 0 0 0 80 failed  98  Address already in use    What the above error is telling is that it was not able to bind nginx to port 80 because it was already in use    To fix this  you need to run the following   yum install net-tools  sudo netstat -tulpn  When you execute the above you will get something like the following   Proto Recv-Q Send-Q Local Address           Foreign Address         State    PID Program name tcp        0      0 0 0 0 0 80              0 0 0 0                 LISTEN      1762 httpd tcp        0      0 0 0 0 0 22              0 0 0 0                 LISTEN      1224 sshd tcp        0      0 127 0 0 1 25            0 0 0 0                 LISTEN      1528 sendmail acce tcp6       0      0    22                                           LISTEN      1224 sshd   You can see that port 80 is blocked by httpd  Apache   This could also be port 443 if you are using SSL    Get the PID of the process that uses port 80 or 443  And send the kill command changing the  lt PID gt  value   sudo kill -2  lt PID gt   Note in my example the PID value of Apache was 1762 so I would execute sudo kill -2 1762  Aternatively you can execute the following   sudo fuser -k 80 tcp  sudo fuser -k 443 tcp  Now that port 80 or 443 is clear  you can start Nginx by running the following   sudo service nginx restart  It is also advisable to remove whatever was previously blocking port 80  amp  443  This will avoid any conflict in the future  Since Apache  httpd  was blocking my ports I removed it by running the following   yum remove httpd httpd-devel httpd-manual httpd-tools mod auth kerb mod auth mysql mod auth pgsql mod authz ldap mod dav svn mod dnssd mod nss mod perl mod revocator mod ssl mod wsgi  Hope this helps

When something cannot bind to a port  it s 5  because it s not started by root  sticky suid bit  sudo  and 94  because another application is already bound to that port   Make sure nginx is really shutdown and you don t try to start it twice by accident   Make sure you don t have Apache or other services running that use port 80   Utilize netstat -a   grep tcp to find out more

I had the same problem when I used Vesta  which uses nginx with apache  The problem was that after applying all updates Apache started listening to 443 for https  The solution was just to comment out the 443 stuff in ports conf  This is because nginx also uses this port

In my case  nginx was not able to open the log file which is located here  var log nginx error log  This was because I had deleted the log directory to free up space in root  which turned out to be stupid   I then created a log folder in var and an nginx folder in log    Then simply run sudo service nginx start

The cause of the issue is this  I already had Apache web server installed and actively listening on port 80 on my local machine   Apache and Nginx are the two major open-source high-performance web servers capable of handling diverse workloads to satisfy the needs of modern web demands  However  Apache serves primarily as a HTTP server whereas Nginx is a high-performance asynchronous web server and reverse proxy server   The inability of Nginx to start was because Apache was already listening on port 80 as its default port  which is also the default port for Nginx   One quick workaround would be to stop Apache server by running the command below  systemctl stop apache2 systemctl status apache2   And then starting up Nginx server by running the command below  systemctl stop nginx systemctl status nginx   However  this same issue will arise again when we try to start Apache server again  since they both use port 80 as their default port   Here s how I fixed it   Run the command below to open the default configuration file of Nginx in Nano editor  sudo nano  etc nginx sites-available default   When the file opens in Nano editor  scroll down and change the default server port to any port of your choice  For me  I chose to change it to port 85    Default server configuration   server          listen 85 default server         listen      85 default server    Also  scroll down and change the virtual host port to any port of your choice  For me  I also chose to change it to port 85    Virtual Host configuration for example com     You can move that to a different file under sites-available  and symlink that   to sites-enabled  to enable it      server            listen 85           listen      85    Then save and exit the file by pressing on your keyboard   Ctrl   S Ctrl   X   You may still be prompted to press Y on your keyboard to save your changes   Finally  confirm that your configuration is correct and restart the Nginx server   sudo nginx -t sudo systemctl restart nginx   You can now navigate to localhost nginx-port  localhost 85  on your browser to confirm the changes   Displaying the default Nginx start page  If you want the default Nginx start page to show when you navigate to localhost nginx-port  localhost 85  on your browser  then follow these steps   Examine the directory  var www html  which is the default root directory for both Apache and Nginx by listing its contents   cd   ls  var www html    You will 2 files listed in the directory   index html                  Apache default start page index nginx-debian html     Nginx default start page   Run the command below to open the default configuration file of Nginx in Nano editor   cd   sudo nano  etc nginx sites-available default   Change the order of the index files in the root directory from this   root  var www html             Add index php to the list if you are using PHP         index index html index htm index nginx-debian html    to this  putting the default Nginx start page - index nginx-debian html in the 2nd position immediately after index    root  var www html             Add index php to the list if you are using PHP         index index nginx-debian html index html index htm    Then save and exit the file by pressing on your keyboard   Ctrl   S Ctrl   X   You may still be prompted to press Y on your keyboard to save your changes   Finally  confirm that your configuration is correct and restart the Nginx server   sudo nginx -t sudo systemctl restart nginx   You can now navigate to localhost nginx-port  localhost 85  on your browser to confirm the changes   That s all   I hope this helps
