Restore/repair nginx after configtest fail
In my LEMP stack my nginx got broken, i wonder if i can fix it or else stille backup some stuff before reverting to a previous snapshot. Lemp was set up with a tut here on DigitalOcean.
So what happened?
After some work in wp multi install (setting up sites/plugins and adding/editing content) i've decided to make a snapshot, i used a terminal with ssh and i entered poweroff.
Which was not smart... Better had i used shutdown
But anyways the snapshot was made. Then, not yet aware of any problems i ran an apt-get update and apt-get upgrade.
With the droplet activated my sites dont work anymore a service nginx configtest returned fail just as service nginx restart does. Reverting to the snapshot ive just made didnt work.
My guess ( i am a novice) is that ubuntu works fine, that just nginx got corrupted.
1 can i exactly diagnose what is wrong, and what is affected? How do i proceed?
2 can i fix nginx if yes how should i do this?
3 if not and i have to revert to an much earlier snapshot, is there a script available to still backup my multisite?
4 could i run xcloner from another location and pull a backup from the droplet over sftp?
apt-get -f install – try to fix broken packages
dpkg --configure -a – try to fix broken
be a good start?
Any help is greatly appreciated!
Working with terminal commands: i am new to it, but exploring
I keep an sftp window open to have some visual feedback
