# They will occasionally require provide prompts for input.

# initial server setup

# step 1 – vim and paste in your public key.
# step 2 – paste in the public key of the app server.
# automate the above.

chmod 600 ~/.ssh/authorized_keys  # set the permissions so only this user is allowed to access it
# check that you can ssh into server with $USR account

# add swap space
# basically following this structure: https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-14-04

# check current setup
sudo swapon -s
free -m
df -h

# create swap file
sudo fallocate -l 8G /swapfile
ls -lh /swapfile # verify
sudo chmod 600 /swapfile
ls -lh /swapfile # verify
sudo mkswap /swapfile
sudo swapon /swapfile
sudo swapon -s # verify
free -m

# make the swap file permanent
sudo vim /etc/fstab
# add this line to bottom of file:
/swapfile   none    swap    sw    0   0

# upate swap configs
sudo sysctl vm.swappiness=10
sudo sysctl vm.vfs_cache_pressure=50

sudo vim /etc/sysctl.conf
# at the bottom add:
vm.swappiness=10
vm.vfs_cache_pressure = 50
