ubuntu 14上的postgres 9.3移动数据目录

Question

after using

sudo chown -R ubuntu:ubuntu /data/psql

/usr/lib/postgresql/9.3/bin/initdb -D /database

and changed the data_directory = '/var/lib/postgresql/9.3/main' to /data/psql'

on starting the a rails app the nginx log is showing:

Error during failsafe response: FATAL: could not open relation mapping file "global/pg_filenode.map": Permission denied

someone have a hint about how to give the permission to the app?

thank's

Answer 1

According to docs :

It's generally recommendable that the PostgreSQL user own not just the data directory but its parent directory as well, so that this should not be a problem.

so changing permission back to postgres would be your solution:

sudo chown -R postgres:postgres /data/psql
