server setup

standards for setting up Ubuntu, node, MongoDB, nginx, pm2 env for stagging and production with one server over an ip address

Version

0.0.1

login as root

$ ssh root@ipnumber

users

add users to group

adduser simon

add user to sudo group:

gpasswd -a simon sudo 

add ssh key to user. on local pc:

cat .ssh/ids_rsa.pub 

if key doesn't exist generate one:

ssh-keygen

• copy id_rsa.pub key

on the server as root switch user:

su - simon

create .ssh dir & .ssh/authorized_keys file, paste the ida_rsa.pub there:

mkdir .ssh
chmod 700 .ssh
vim .ssh/authorized_keys

change premissions:

chmod 600 .ssh/authorized_keys

restart ssh service to apply changes

service ssh restart

Firewall basics

allow ssh:

sudo ufw allow ssh

allow specific ports for ssh, http, ssl/tls:

sudo ufw allow 4444/tcp
sudo ufw allow 80/tcp
sudo ufw allow 81/tcp
sudo ufw allow 443/tcp

show allowed and enable firewall

sudo ufw show added
sudo ufw enable

Timezone

configure server timezone

sudo dpkg-reconfigure tzdata

• a menu will open, choose your city

configure NTP to stay in sync with other servers:

sudo apt-get update
sudo apt-get install ntp

install packages

####nodejs, npm, express, bower:

sudo apt-get update
sudo apt-get install nodejs

sudo apt-get install npm

npm install express -g
npm install bower -g

####MongoDB

import public key

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10

create a list file:

echo "deb http://repo.mongodb.org/apt/ubuntu "$(lsb_release -sc)"/mongodb-org/3.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list

reload

sudo apt-get update

install stable:

sudo apt-get install -y mongodb-org

start

sudo service mongod start

nginx configuration

install

sudo apt-get update
sudo apt-get install nginx

start

sudo service nginx start

Create the file yourdomain at /etc/nginx/sites-available/:

vim /etc/nginx/sites-available/yourdomain

something like:

#the IP(s) on which your node server is running. I chose port 3000 for production and 8000 for stagging.

}

• save and quit

link your file to site-enabled to apply changes:

cd /etc/nginx/sites-enabled/ 
ln -s /etc/nginx/sites-available/yourdomain yourdomain

restart

sudo /etc/init.d/nginx restart

PM2

one server as root:

sudo npm install pm2 -g

as user (simon):

try:

pm2 list

if error (EACCES, permission denied ) then you have to give permissions to user:

sudo chmod -R 777 .pm2

change .pm2 ownership

chown nobody:nogroup -R .path

run an app:

pm2 start bin/www

to start on boot:

sudo env PATH=$PATH:/usr/bin pm2 startup ubuntu -u simon

then save processes:

pm2 save

• now when rebooting system, your app should run on start

deploy app remotely:

add ecosystem.json file to your project (example):

{
    apps: [
        {
            name: "heatinc-stagging",
            script: "bin/www",
            env: {
                NODE_PORT: 8000,
                env: "production"
            }
        }
    ],
    deploy: {
        stagging: {
            user: "simon",
            host: "104.236.241.255",
            ref: "origin/master",
            repo: "git@github.com:Digitiv-Inc/heat-inc.git",
            path: "~/www/stagging",
            "post-deploy": "npm run deploy; export NODE_PORT=8000; pm2 startOrRestart ecosystem.json -f --env production",
            env: {
                NODE_PORT: 8000
            }
        }
    }
}

push setup to server (remotely):

pm2 deploy ecosystem.json stagging setup

deploy app on server (remotely):

pm2 deploy ecosystem.json stagging

• now on server your stagging app should be running
• to check

pm2 list
