Kernel Selection: UEK vs RHCK
Oracle Linux offers two kernel options:
| Kernel | Description | NFS nconnect |
|---|---|---|
| UEK 7 (OL9) | Unbreakable Enterprise Kernel | Supported |
| UEK 6 (OL8) | Unbreakable Enterprise Kernel | Supported |
| RHCK | Red Hat Compatible Kernel | Supported |
Recommendation: Use UEK for better performance and latest features.
# Check current kernel
uname -r
# List available kernels
sudo dnf list installed kernel*
# Switch to UEK (if using RHCK)
sudo dnf install -y kernel-uek
sudo grubby --set-default /boot/vmlinuz-*uek*Package Installation
# Install NFS utilities
sudo dnf install -y nfs-utils rpcbind
# Enable services
sudo systemctl enable --now nfs-client.target rpcbind
# Verify installation
rpm -qa | grep nfsSELinux Configuration
SELinux is enabled by default on Oracle Linux:
# Allow NFS home directories
sudo setsebool -P use_nfs_home_dirs 1
# Allow httpd to use NFS (if applicable)
sudo setsebool -P httpd_use_nfs 1
# Check NFS-related booleans
getsebool -a | grep nfs
