Nginx- error: bind() to 0.0.0.0:80 failed. permission denied

localhostnetworkingnginxport

I am trying to run Nginx, but I am getting the error below:

bind() to 0.0.0.0:80 failed (10013: An attempt was made to access a
socket in a way forbidden by its access permissions)

Please provide some help on what changes I need to do to make it working?

I have tried running on ports other than 80 and it works. but I need it to be running on 80.

Note: I am running on Windows 7 with command prompt running as Administrator.

If the port is already in use, you can change the default port of 80 to a different port that is not in use (maybe 8070). In conf\nginx.conf:

server {
    listen       8070;
    ...
}

After startup, you should be able to hit localhost:8070.

i fixed this by running sudo apachectl stop - turns out apache was running in the background and prevented nginx from starting on the desired port.

On ubuntu run sudo /etc/init.d/apache2 stop

I had a similar error after php update. PHP fixed a security bug where o had rw permission to the socket file.

Open /etc/php5/fpm/pool.d/www.conf or /etc/php/7.0/fpm/pool.d/www.conf, depending on your version.

Uncomment all permission lines, like:

listen.owner = www-data
listen.group = www-data
listen.mode = 0660

Restart fpm - sudo service php5-fpm restart or sudo service php7.0-fpm restart

Note: if your webserver runs as user other than www-data, you will need to update the www.conf file accordingly
