RHEL wsgi nginx error: permission denied while connecting to upstream




I had the same issue. What I found is that "SELinux" was blocking nginx from using the socket. If SELinux is enabled you can check the status (which should look similar to below):

[root@localhost ~]# sestatus
SELinux status: enabled
SELinuxfs mount: /selinux
Current mode: enforcing
Mode from config file: enforcing
Policy version: 21
Policy from config file: targeted



You can add an NGINX SELinux policy or just disable SELinux to get around the issue. 

  • Check the status of SELinux using 
    #sestatus
  • If it says enabled, vi into /etc/sysconfig/selinux. This is a symlink to /etc/selinux/config so modify this file in case you don't find the above file. 
    Terminal command: sudo vi /etc/sysconfig/selinux

    The file is highly self-explanatory. Just change the value of         SELINUX to "disabled" -- without quotes.
