In the main server block (e.g. /etc/nginx/nginx.conf) add the following:

        if ($http_user_agent ~* (AgentName) ) {
        return 403;
        }

Test nginx config and restart:

nginx -t
service nginx restart

To test the agent gets blocked:

curl -I -H 'User-agent: AgentName' localhost/bla

HTTP/1.1 403 Forbidden

Create the following conf file:

vim /etc/nginx/conf.d/blockips.conf

Enter the following e.g. :

deny 1.2.3.4;
deny 95.32.45.0/24;

Restart nginx

Set the perfect permissions for WordPress:

cd /path/to/wp/webroot; find . -type d -print0|xargs -0 chmod 755; find . -type f -print0|xargs -0 chmod 644; chown nginx:nginx * -R

*Update nginx:nginx to your web daemon user and group

Recently had an issue where I was unable to upload media within WordPress. Turned out the user and group in php-fpm’s www.conf was incorrect. To fix:

vim /etc/php-fpm.d/www.conf

user: nginx
group: nginx

Restart php-fpm

service php-fpm restart

1. Check the nginx stub_status_module is enabled:

nginx -V 2>&1 | grep -o with-http_stub_status_module

This should result in:

with-http_stub_status_module

If not, install nginx with stub_status_module enabled.

2. Add the following code to the server block:

server {
listen 80 default_server;
# Define the document root of the server e.g /var/www/html
root /var/www/html;
location /nginx_status {
# Enable Nginx stats
stub_status on;
# Only allow access from your IP e.g 1.1.1.1 or localhost #
allow 127.0.0.1;
allow 1.1.1.1
# Other request should be denied
deny all;
}

*Set allow IP to the sources you need access from*

3. Browse to http(s)://example.com/nginx_status
