hello expert,
I had to do a backup on replication master-slave servers. I also have asked this question before, but I don't understand why I followed the information and same scripting to run on the replication servers and didn't work. I can run pg_dumpall successful but not with the script. Would you please tell me what's wrong and what need to correct the error?
my replication server (master) pg_hba.conf
# "local" is for Unix domain socket connections only
local all all peer
host all all 192.168.2.0/24 trust
# IPv4 local connections:
host all all 127.0.0.1/32 indent
local all postgres trust
host all power_user 0.0.0.0/0 md5
host all other_user 0.0.0.0/0 md5
host all storageLoader 0.0.0.0/0 md5
# IPv6 local connections:
host all all ::1/128 indent
#allow replication connections from localhost, by a user with the replication priviledge
local replication all trust
host replication all 127.0.0.1/32 trust
host replicaiton all ::1/128 trust
host replication replicauser masterIP/32 trust
host replicaiton replicauser slaveIP/32 trust
from the postgres prompt I can connect to each database
#psql -d template0 -U postgres
template0-#
#psql -d template1 -U postgres
template1-#
#psql -d pscidr -U postgres
pscidr-#
#psql -d postgres -U postgres
postgres-#
when I run the script as postgres os, I don't see the error but the only global.sql backup but nothing in it, 0 byte (blank) sql script.
when I run as root su -c postgres /path/pg_backup.sh > pgbackup.log, I get below:
Performing globals backup:Globals backuppg_dumpall: could not connect to database "template1":FATAL: Ident authentication failed for user "postgres" fro globals backup.Performing schema-only backup:psql:FATAL: Ident authentication failed for user "postgres"the following databases were matched for schema-only backup:performing full backup:psql:FATAL: Ident authentication failed for user "postgres"
I can run pg_dumpall > postgresdump.sql as postgres user os fine will all the databases backup
pg_backup.sh and pg_backup.config attachment.
v/r,
