How to change log directory location in postgresql 9.4? - database

Question

my current log_directory path is
**/opt/demo/PostgreSQL/9.4/data/pg_log**
I'm trying to change the log directory path to
**/logs/demo/**
The server won't start when i uncomment the log path and it starts only when its default.
The postgresql.conf file looks like
# ERROR REPORTING AND LOGGING
#------------------------------------------------------------------------------
# - Where to Log -
log_destination = 'stderr' # Valid values are combinations of
# stderr, csvlog, syslog, and eventlog,
# This is used when logging to stderr:
logging_collector = on
# These are only used if logging_collector is on:
#log_directory = '/logs/etbos/demo/' #directorywherelogfiles are written
#log_filename = 'postgresql-%Y-%m-%d_%H%M%S.log' # log file name pattern,
# These are relevant when logging to syslog:
#syslog_facility = 'LOCAL0'
#syslog_ident = 'postgres'
# This is only relevant when logging to eventlog (win32):
#event_source = 'PostgreSQL'

So this is what I supposed :) You need to grant permissions to the new log directory to postgres user.
You can do this using f.e.:
sudo chown postgres:postgres /your/new/log/dir/path
Answering your other question:
To allow TCP/IP connections from remote hosts you need to edit pg_hba.conf file.
You can allow ALL TCP/IP connections by adding a line like this:
host all all 0.0.0.0/32 md5
There are five parameters above, you can read about them in the pg_hba.conf file in the comments at the top of the file, but in short they mean:
[connection_type] [database_name] [user_name] [remote_ip/mask] [auth_type]
