Nominatim Server Setup
Hello
Please contact me [removed]
I can help you out.
My issue is with server config - I have it working on Ubuntu with a very small db (Fiji) but cannot import larger DB without the import process failing due to lack of memory even when using reverse geocoding only option.
Any pointers on correct config for low memory system?
Open Cart I emailed you but never heard back.
I got this sorted and have successfully built two nominatim servers each on Ubuntu with no problems. I have kept my instructions and notes so if anyone needs help let me know.
Visiondrive...can you send me instruction how to build a nominatim server. Thank u in advance
Hello visiondrive.
How i can reach you to get the instructions. I has been struggling with this problem for a couple of week. Very grateful for any help. Best regards. Enrique
My issue was that the VPS's I was using had very limited RAM but you can work around using a swap file as per notes below - I ended up installing UBUNTU in a VM on a windows server in Virtual Box and assigning it more cpu and ram than it needed to make it all work for the data processing and then lowered it back afterwards. TRACCAR runs on the same server so the reverse lookup is all on the same machine.
Here are my swap notes if needed.
root@vps258452:~# sudo fallocate -l 2G /swapfile
root@vps258452:~# sudo chmod 600 /swapfile
root@vps258452:~# sudo mkswap /swapfile

root@vps258452:~# sudo swapon -a
sudo swapon /swapfileNow onto NOMINATIM...

If the process fails you need to delete the database and start the import again.

Jay you can find the files at this link - the australian files were linked above in my example as this is what I used.
Thank will give it a shot..thank you sir
visiondrive
Thank you very much. I really apreciate the help.
does anybody have an update instruction on setting up this nominatim server
Will a 4gig memory on a vps server be sufficient to run this.
I have a Nominatim server working fine that Anton configured for me but I would like to set one up for myself.
Why you ask?
Lets just say that as an Engineer is pains me when I try to get things working and cannot - I have spent the good part of nearly two days following the various sites with zero success and as linux is not high in my skill set I am seeking some help/mentoring.
If you have what it takes to help me out step by step I am more than happy to pay for your time.
Like I said above - I already have one working but I want to set one up on my own so I know how it all works config wise and learn some linux on the way.
Anyone interested?
