4.4.2. Sharing NFS and CIFS file systems

By default, NFS mounts on the client side are labeled with a default context defined by policy for NFS file systems. In common policies, this default context uses the nfs_t type. Also, by default, Samba shares mounted on the client side are labeled with a default context defined by policy. In common policies, this default context uses the cifs_t type.
Depending on policy configuration, services may not be able to read files labeled with the nfs_t or cifs_t types. This may prevent file systems labeled with these types from being mounted and then read or exported by other services. Booleans can be turned on or off to control which services are allowed to access the nfs_t and cifs_t types.
Turn the httpd_use_nfs Boolean on to allow httpd to access and share NFS file systems (labeled with the nfs_t type. Run the setsebool command as the root user to turn the Boolean on:
setsebool -P httpd_use_nfs on

Turn the httpd_use_cifs Boolean on to allow httpd to access and share CIFS file systems (labeled with the cifs_t type. Run the setsebool command as the root user to turn the Boolean on:
setsebool -P httpd_use_cifs on

Note

Do not use the -P option if you do not want setsebool changes to persist across reboots.
