Installation 2.0

Setup User

1. Add user

adduser username

2. Make the user a sudoer

usermod -aG sudo username

Setup GITHUB machine user access

1. create .ssh directory

mkdir ~/.ssh

2. Create RSA keys and set a passphrase

ssh-keygen -t rsa -b 4096 -C "[email protected]"

3. Adding your SSH key to the ssh-agent

eval "$(ssh-agent -s)"

4. Set the Identity file in the .ssh/config

nano ~/.ssh/config

Host *
  AddKeysToAgent yes
  UseKeychain yes
  IdentityFile ~/.ssh/id_rsa

5. Go ahead and add the SSH public key to GITHUB 👍

6. Copy the ssh keys to the working machines and gain access to the server

Hack to make sure the passphrase is not asked everytime

1. Edit .bashrc file

nano ~/.bashrc

2. Add the following content

SSH_ENV=$HOME/.ssh/environment

# start the ssh-agent
function start_agent {
    echo "Initializing new SSH agent..."
    # spawn ssh-agent
    /usr/bin/ssh-agent | sed 's/^echo/#echo/' > ${SSH_ENV}
    echo succeeded
    chmod 600 ${SSH_ENV}
    . ${SSH_ENV} > /dev/null
    /usr/bin/ssh-add
}

if [ -f "${SSH_ENV}" ]; then
     . ${SSH_ENV} > /dev/null
     ps -ef | grep ${SSH_AGENT_PID} | grep ssh-agent$ > /dev/null || {
        start_agent;
    }
else
    start_agent;
fi

3. Save the file and re-open the terminal, you might need to enter the passphrase once but then it shouldn't be prompted again

Set up local machine access

1. Copy over the keys to the local machine

2. Use ssh-copy-id to enable ssh access

ssh-copy-id -i <key-path> <username>@<server>

Install Docker

1. Update registry

sudo apt-get update

2. Uninstall any old versions of docker

sudo apt-get remove docker docker-engine docker.io

2. Add the connected user "$USER" to the docker group. Change the user name to match your preferred user if you do not want to use your current user

sudo gpasswd -a $USER docker

 sudo usermod -aG docker $USER

3. Either do a newgrp docker or log out/in to activate the changes to groups.

4. Install docker-compose

sudo apt install docker-compose

Install NodeJS and NPM

4. Install LTS version of NodeJS

nvm install --lts

5. Set it as the default for the system

nvm alias default <version number>
