How to give root files permision to postgres

Posted April 8, 2016 8k views
PostgreSQL

I’ve installed posgres on a ubuntu droplet. I have some files the I cloned to the root users account under the directory of mapnik/data. The exact file I am interested in is

/root/mapnik/data/world_merc.shp

When I log in as postgres and try to import this file from the root I get an error of “unable to open”. The exact command I am using to import is
shp2pgsql -s 4326 -a /root/mapnik/data/world_merc.shp | psql -h localhost -d postgres -U

I am guessing this is because postgres cannot read from the root user’s files? Any help to get this resolved

Hi there,

What are the file permissions on the file you are trying to import?

You can find out the file permissions by typing:

ls -al /root/mapnik/data/world_merc.shp

If the owner and the group are root, you may need to change ownership of the file to the postgres user to access it.

You can change the ownership of the file by typing:

sudo chown postgres:postgres  /root/mapnik/data/world_merc.shp

That should allow you to import it into the psql command.

Cheers
