I have installed wordpress using this guide https://www.digitalocean.com/community/articles/how-to-install-wordpress-with-nginx-on-ubuntu-12-04

Now site working fine but I am facing errors when I try to install W3 total cache.

I get the following error:

FTP credentials don’t allow to write to file /var/www/nginx.conf

W3 Total Cache Error: Files and directories could not be automatically created to complete the installation.

Please execute commands manually

or use FTP form to allow W3 Total Cache make it automatically.

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

.htaccess File Permission Error Due to the security plugins, other plugins lost their writing permission to .htaccess and other files. The solution is simple. Check the directory permission level is 755 (in case WordPress installed in the directory). Now check the file permission for .htaccess which is necessary to be 644 . Otherwise, you will encounter the error. Source: DoubtSolver

@ajinkyathete : Once you update it, make sure you change its ownership back to root:

sudo chown root /var/www/nginx.conf

.

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.

michael.chesterton · Answer

it gets written to when you update or save w3 settings, assuming php-fpm has write access to it.

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 · Answer

you were suppose to create /var/www/nginx.conf like I said in my first message

ajinkyathete · Answer

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

ajinkyathete · Answer

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

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

}
