  3. tar -xzvf openresty-1.13.6.1.tar.gz–Unzip the installation package
  4. cd openresty-1.13.6.1–Enter file
  5. ./configure --prefix=/usr/server/openrest–Install openresty to / usr / server / openresty (create the directory yourself)
  6. make, make install–Compile and install
  7. usr/server/openresty/nginx/sbin/nginx–Enable nginx

PM2 boot project and boot auto start

1.npm install pm2 -g–Command line global installation of PM2

2. I use express to create projects

CD usr / server / spider news / bin -- find the project address first
pm2 start www
pm2 save
pm2 startup

Nginx is added to system services and bootstrap

1. Enter the / etc / init. D directory to create the nginx script (change the path to the address of your nginx)

PROGRAM=/usr/server/openresty/nginx/sbin/nginx

test -x $PROGRAM || exit 0
case "$1" in
  start)
     log_begin_msg "Starting Nginx server"
     /usr/server/openresty/nginx/sbin/nginx
     log_end_msg 0
     ;;
  stop)
     PID=`cat /usr/server/openresty/nginx/logs/nginx.pid`
     log_begin_msg "Stopping Nginx server"
     if [ ! -z "$PID" ]; then
        kill -15 $PID
     fi
     log_end_msg 0
     ;;
  restart)
     $0 stop
     $0 start
     ;;
  *)
     log_success_msg "Usage: service nginx {start|stop|restart}"
     exit 1
esac
exit 0

2. Then run the following command:

sudo chmod +x nginx
sudo update-rc.d nginx defaults

Then boot nginx will automatically start, at the same time you can use the following command

sudo service nginx start
sudo service nginx stop
