Backend deployment

Pull backend code

cd /home/closet/closet/backend    # change directory
git fetch --all                   # fetch all
git reset --hard origin/master    # remove all local chanegs!!!
npm install                       # if not installed
npm run test                      # feel free to run test to check

Run as service closet-backend

• Service is set to restart on fail or on reboot
• Partial environemnt variable is set already in the service file

sudo systemctl status closet-backend    # check status (partial log)
sudo systemctl start closet-backend     # start service
sudo systemctl stop closet-backend      # stop service
sudo systemctl restart closet-backend   # restart service
sudo systemctl enable                   # enable to run on boot

Service log

• Should also put into another location so we can have a clean log for each start of backend

journalctl -u closet-backend          # all logs (use SHIFT-G to go to the bottom)
journalctl -u closet-backend -f       # follow low

Modify service

• A copy of service file is in this repository closet/backend/closet-backend.service

sudo vim /lib/systemd/system/closet-backend.service   # edit service file
sudo systemctl daemon-reload                          # reload service file
sudo systemctl start closet-backend                   # start service

sudo chmod +x /home/closet/closet/backend/index.js    # add exceutable permissions to express app
sudo chmod go+w /home/closet/closet/backend           # allows any users to write the app folder (for using fs)
