## node-gyp on small servers

node-gyp needs more ram or swap space to install. Use these commands to create swap space as root. (if using sudo, then put the following in a file and then run it using sudo).

>  Assumes you have Ubuntu. Should work for most Debian-based OSes.

These are quick copy-paste commands. Look at the end for info.

```
# feel free to change below values
export SWAP_PATH=/swap
export SWAP_SIZE=2097K

touch $SWAP_PATH
chmod 0600 $SWAP_PATH

dd if=/dev/zero of=$SWAP_PATH bs=1024 count=$SWAP_SIZE
mkswap $SWAP_PATH
swapon $SWAP_PATH
echo "$SWAP_PATH  none  swap  sw  0  0" >> /etc/fstab
echo 10 | tee /proc/sys/vm/swappiness
echo "vm.swappiness = 10" | tee -a /etc/sysctl.conf
```

then as a user that uses `npm`, run following:

```
npm config set jobs 1
```

### info

* `SWAP_PATH` is the path to create the swap
* `SWAP_SIZE` is the size of the swap. We set it at around 2gb
  * swap size in 1kb blocks
  * 2048mb * 1024kb == 2097152
  * which is approximately 2097 thousand ( == 2097k)
