Nginx: Permission denied for nginx on Ubuntu [closed]

I am new to system administration. After installing nginx via puppet on Ubuntu I get the following output:

[alert] could not open error log file: open() "/var/log/nginx/error.log" failed (13: Permission denied)

[warn] 1898#0: the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:1

[emerg] 1898#0: open() "/var/log/nginx/access.log" failed (13: Permission denied)

How do I get rid of all of these messages?

I don't want to use command line directly (chown / chmod) and repeat it every time I create a new server. Therefore, I am thinking of what has to be added to the puppet manifest.

What is the best sysadmin practice in this case: to change owner / permissions for /var/log/nginx or to store logs in different location? If chown / chmod is the way to go, which specific permissions would ensure the highest level of security?

I tried this, but it didn't help:

  file { '/var/log/nginx':
    ensure  => directory,
    mode    => '0755',
    owner   => 'www-data',
    group   => 'www-data',
    recurse => true
  }

Edited:

vagrant@precise64:~$ ps aux | grep [n]ginx

Make sure you are running the test as a superuser.

sudo nginx -t

Or the test wont have all the permissions needed to complete the test properly.


I faced similar issue while restarting Nginx and found it to be a cause of SeLinux. Be sure to give a try after either disabling SeLinux or temporarily setting it to Permissive mode using below command:

setenforce 0

I hope it helps :)
