Try using 'easyengine', it will automate the process of installing and configuring Nginx + PHP-FPM + MySQL + Postfix + WordPress + W3TC + many more options

    THANK YOU!
    I was struggling with that problem in WordPress, and I didn’t get just the solution for my specific problem, I found a super fast way to install WordPress. All thanks to you!

uninstall ftp
log into your droplet using ssh

$ sudo touch /var/www/nginx.conf
$ sudo chown www-data /var/www/nginx.conf

The second line assumes php-fpm is running as user www-data, which I think it does by default on ubuntu

you'll also need to edit you nginx config and include that file inside your server block

Sorry, these may be stupid questions but I just don't want to mess things up.

What command should I use to uninstall ftp?
Which file should I include inside server block?
How to edit nginx cofig?

Thanks

sudo apt-get remove vsftpd

you need to include /var/www/nginx.conf inside your server block in /etc/nginx/sites-enabled/wordpress

sudo nano /etc/nginx/sites-available/wordpress

after the

location ~ \.php$ {
...
}

block, add a line

include /var/www/nginx.conf ;

then there should be your closing server brace already in the file

}

I did as you said. After that no changes occured so I thought of restarting nginx and I got this error

sudo service nginx restart
Restarting nginx: nginx: [emerg] open() "/var/www/nginx.conf" failed (2: No such file or directory) in /etc/nginx/sites-enabled/wordpress:66
nginx: configuration file /etc/nginx/nginx.conf test failed

Now whole site is down.

Oops! Google Chrome could not connect to

Please help

Now Nginx is running when I removed the line include /var/www/nginx.conf ;

michael.chesterton April 17, 2014
you were suppose to create /var/www/nginx.conf like I said in my first message
ajinkyathete April 17, 2014
Really Thanks man.
I guess its working.W3 total cache not showing any errors.
However when I open /var/www/nginx.conf this file shows blank.
What should I edit in this file? Do I need to add something?
And at last should I restart nginx?
michael.chesterton April 17, 2014
it gets written to when you update or save w3 settings, assuming php-fpm has write access to it.
ajinkyathete April 17, 2014
How to know if php-fpm has write access? I used this commands.

$ sudo touch /var/www/nginx.conf
$ sudo chown www-data /var/www/nginx.conf

Anyways when I change w3 settings everything is working fine.

So, should I consider everything is successful.

@ajinkyathete: Once you update it, make sure you change its ownership back to root: 
sudo chown root /var/www/nginx.conf

.htaccess File Permission Error
Due to the security plugins, other plugins lost their writing permission to .htaccess and other files. The solution is simple.

  1. Check the directory permission level is 755 (in case WordPress installed in the directory).
  2. Now check the file permission for .htaccess which is necessary to be 644. Otherwise, you will encounter the error.
