Nginx PhpMyadmin error: 413 Request Entity Too Large

A 413 Nginx error occurred while uploading the database through phpMyAdmin.  the requested entity was too large as per the error. 

Solution : 

If you are trying to upload large files and are seeing this error, it means the client_max_body_size value is too low.

You may access the Nginx configuration file with the command:

sudo nano /etc/nginx/nginx.conf

It may also be located in /usr/local/nginx/conf/nginx.conf or /usr/local/etc/nginx/nginx.conf.

Add the following line within the http block

http {

    . . .

    client_max_body_size 128M;

    . . .

}

Save and exit (press CTRL + X, press Y and then press ENTER)

Now, check if the Nginx config file syntax is valid.

sudo nginx -t

If valid, restart Nginx service.

sudo systemctl restart  nginx

You may also need to edit the php.ini config file.

Done!
