pm2

• sudo npm i pm2 -g
• sudo: some apps can only work when running with sudo, in this case every command must be run as sudo (sudo pm2 start dist/bundle.js, sudo pm2 logs...); because the apps of each user are kept separate
• pm2 start app_path
• pm2 startup = set autostart (app will restart automatically after reboot)
• pm2 logs appname, pm2 flush appname = display and empty logs, if no app name is given, operate in every app

nginx

• sudo apt install nginx
• sudo vim /etc/nginx/sites-available/default
• sudo nginx -t = test if nginx config is ok
• sudo service nginx restart

• go to new user's home directory, chown gusalbukrk:gusalbukrk -R /home/gusalbukrk/.ssh/ to change ownership
• usermod -aG sudo gusalbukrk = new user will be able to use sudo
