Nginx Permission denied for nginx on Ubuntu

Question

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    gt  directory      mode      gt   0755       owner     gt   www-data       group     gt   www-data       recurse   gt  true       Edited   vagrant precise64    ps aux   grep  n ginx root      1001  0 0  0 1  62908  1388          Ss   08 47   0 00 nginx  master process  usr sbin nginx www-data  1002  0 0  0 1  63260  1696          S    08 47   0 00 nginx  worker process www-data  1003  0 0  0 1  63260  1696          S    08 47   0 00 nginx  worker process www-data  1004  0 0  0 1  63260  1696          S    08 47   0 00 nginx  worker process www-data  1005  0 0  0 1  63260  1696          S    08 47   0 00 nginx  worker process

if you don t want to start nginx as root   first creat log file    sudo touch  var log nginx error log  and then fix permissions   sudo chown -R www-data www-data  var log nginx  sudo find  var log nginx -type f -exec chmod 666        sudo find  var log nginx -type d -exec chmod 755

Permission to view log files is granted to users being in the group adm   To add a user to this group on the command line issue   sudo usermod -aG adm  lt USER gt

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

For me  I just changed the selinux from enforcing to permissive and then I was able to start nginx without any error

If i assume that your second code is the puppet config then i have a logical explaination  if the error and log files were create before  you can try this  sudo chown -R www-data www-data  var log nginx  sudo chmod -R 755  var log nginx

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

just because you don t have the right to acess the file   use  chmod -R 755  var log nginx    or you can change to sudo then it
