Linux Administration

Here are a few useful commands to use during Linux administration of your Splynx server.

Linux administration/Linux disk usage

To check disk usage on Linux, the following command can be used to install the "NCDU" package:

apt-get install ncdu

Linux administration/Create swap file

To create a swap-file, the following commands can be used:

if [[ ! -f /swapfile ]]; then
    echo "Building swapfile..."
    dd if=/dev/zero of=/swapfile bs=64M count=32
    mkswap /swapfile
    chmod 0600 /swapfile
    swapon /swapfile

    # Mount on reboot
    if [[ -z "$(cat /etc/fstab | grep swapfile)" ]]; then
        echo "/swapfile none swap sw 0 0" | tee -a /etc/fstab > /dev/null 2>&1

This will create a 2 GB file, if you need more or less, please change bs=64M count=32 - 32 to 16 for 1 GB, 64 for 4 GB.
