Hi Gang,

Is there a way to backup via SSH? I have one hotspot that's decided the NGNIX server needed a vacation, and I can't access via HTTP.. Is there a way to backup my settings via SSH?

Thanks.

I'm assuming you plan on backing up your configuration and then restoring with a new image, correct?

But before doing that, let's see what wrong with your existing system. What results do you get when you run the following?

Code: Select all

sudo systemctl status nginx.service
sudo systemctl status php7.0-fpm.service
cat /var/log/nginx/error.log

(might want to boot your system first before running these commands so the resulting messages are current and haven't yet been rotated off.)

Also, have you run a successful system update/upgrade recently?

Code: Select all

rpi-rw
sudo apt update
sudo apt upgrade
rpi-ro

Thanks for the tips.. here's what I see. As far as I can tell, nothing looks.. wonky...

FPM (Fast CGI Process Manager) does NOT look normal: it should not be in a "failed" state. (Out of curiosity, when's the last time you booted?)

So, if a reboot doesn't clear this up, then my guess is that a config file or link for FPM is corrupted; a reinstall may fix that but that's an iffy proposition - all installs are not created equal.

We can dig a little deeper, if you want; try running this and see if we can get a hint as to what's wrong with FPM:

Code: Select all

sudo systemctl restart php7.0-fpm.service
sudo systemctl status php7.0-fpm.service
sudo cat /var/log/php7.0-fpm.log

But, if you just want to quickly move along, then run this to back up your config (and manually copy the resulting .zip file out of the /tmp directory) and then proceed on to rebuilding your system:

Code: Select all

#!/bin/bash
# backup Pi-Star configuration files from SSH command line
#
backupDir='/tmp/config_backup'
#
sudo rm -rf $backupDir 2>&1
sudo mkdir $backupDir 2>&1
if (cat /etc/dhcpcd.conf | grep "static ip_address" | grep -v "#"); then
  sudo cp /etc/dhcpcd.conf $backupDir 2>&1
fi
sudo cp /etc/wpa_supplicant/wpa_supplicant.conf $backupDir 2>&1
sudo cp /etc/ircddbgateway $backupDir 2>&1

Well, now I have bigger problems than just the web server.. the PI is no longer powering the hat... So, who knows...

Thanks for the tips...
