I have a a file in remote directory which is moulted to apache DocRoot tree. When I try to download a file (not write) from that dir I get 403:
AH00037: Symbolic link not allowed or link target not accessible: /var/www/b2b/web/var
What I tried:
- Selinux is disabled
Options +FollowSymLinksis present- If I replace link to another FS with link on the same FS - it works!
The file:
namei -l /var/www/b2b/web/var/assets/75259_box1_v29.jpg
f: /var/www/b2b/web/var/assets/75259_box1_v29.jpg
dr-xr-xr-x root root /
drwxr-xr-x root root var
drwxr-xr-x root root www
drwxrwxrwx www-data www-data b2b
drwxrwxrwx www-data www-data web
lrwxrwxrwx root root var -> /var/www/b2b/nfs/b2b-web-var
dr-xr-xr-x root root /
drwxr-xr-x root root var
drwxr-xr-x root root www
drwxrwxrwx www-data www-data b2b
drwxrwxrwx www-data www-data nfs
drwxrwxrwx www-data www-data b2b-web-var
drwxrwxrwx www-data www-data assets
-rwxrwxrwx www-data www-data 75259_box1_v29.jpg
So, in /var/www/b2b/web/ I have:
lrwxrwxrwx 1 root root 28 Oct 3 09:10 var -> /var/www/b2b/nfs/b2b-web-var
I've created var1 which has same content as /var/www/b2b/nfs/b2b-web-var, if I do like below (link is local) then everything works:
lrwxrwxrwx 1 root root 4 Oct 3 18:15 var -> var1
drwxr-xr-x 4 root root 4096 Oct 3 18:13 var1
/etc/fstab:
fs-1111111111:/ /var/www/b2b/nfs efs defaults,_netdev 0 0
DocumentRoot is /var/www/b2b/web
Also I tried strace, but cannot understand what exactly is wrong:

I thought about timeouts but I can read the file content using su apache then e.g. with head /var/www/b2b/web/var/assets/75259_box1_v29.jpg | less.
So, what's wrong here?
