server day !

start with checking the server hosts i have saved?

cat /etc/hosts

used to have old free oracle cloud servers that werent being used, reset/remade servers

fix server wiring and /etc/hosts file to update it

for convenience when ssh-ing into the server,

in .ssh directory, see contents of config file

cat config
IdentityFile=~/.ssh/julia7hk

UseKeychain yes
AddKeysToAgent yes

Host oc03
    User ubuntu

Host data
    User kang616

Host borg01
    Hostname borg01.cs.purdue.edu
    User kang616

log in to server

ssh ubuntu@oc03

things to have bot.py run:

  1. screen
  2. clone github repo
  3. install pyenv, etc etc

copy my ssh key into server so that i can git clone my repo onto server

scp julia7hk ubuntu@oc03:/home/ubuntu/.ssh

install pyenv on the server (ubuntu)

Installing Pyenv on Ubuntu involves a few steps, primarily using the pyenv-installer script for simplicity.

1. Update System and Install Dependencies:

Before installing Pyenv, update your system’s package list and install necessary build dependencies for Python:

Code

sudo apt update
sudo apt install -y make build-essential libssl-dev zlib1g-dev libbz2-dev \libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev \xz-utils tk-dev libffi-dev liblzma-dev git

2. Install Pyenv using pyenv-installer:

The pyenv-installer script simplifies the installation process:

curl https://pyenv.run | bash

3. Configure your Shell Profile:

The installer will likely provide instructions to add Pyenv to your shell’s environment. You typically need to add lines similar to these to your ~/.bashrc (or ~/.zshrc if you use Zsh):

Code

echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrcecho 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrcecho -e 'if command -v pyenv 1>/dev/null 2>&1; then\n eval "$(pyenv init -)"\nfi' >> ~/.bashrc

now double check cat ~/.bashrc

you should see

export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
if command -v pyenv 1>/dev/null 2>&1; then
  eval "$(pyenv init -)"
fi

appended to the end of your .bashrc file 😁

(since thats exactly what the command above is doing)

now exit and ssh back into server

pyenv should be setup on server

now install python 3.11 on the server

pyenv install 3.11
