I have two RHEL 7 machines.
I have installed nginx and php-fpm and setup a nfs mount. I can read/write to the nfs mount without issues and I have another application server (Apache Geronimo) that is able to read write to it.
When I installed nginx it setup a nginx user which I created on the NFS file server with the same uid and gid.
I am able to list out files on the nfs client mount using the nginx user. However when I tried to serve up static html or dynamic php files using nginx from the nfs I get a permission error:
*5 stat() "/usr/depot/repository/test.php" failed (13: Permission denied)
*5 open() "/usr/depot/repository/test.html" failed (13: Permission denied)
In addition I created folder under /usr/depot/testing with the same permissions (just wasn't nfs) and that worked just fine.
Here is the mounting info on the client.
xxx.xxx.xxx.xxx:/mnt/repository on /usr/depot/repository type nfs4 (rw,nosuid,nodev,noexec,relatime,vers=4.0,rsize=524288,wsize=524288,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=xxx.xxx.xxx.xxx,local_lock=none,addr=xxx.xxx.xxx.xxx)
I can't see anything wrong with this setup so I'm at a loss as to why nginx can't read the files from the nfs share.
Update
Ok I just disabled SELinux reboot and that fixed it. Now the question is how do I configure SELinux so that nginx can access the remote server.
