Thread: listening on an address other than 'localhost'?

listening on an address other than 'localhost'?

From
"Johnson, Bruce E - (bjohnson)"
Date:
per the documentation to listen for client connections on a given IP address you set listen_addresses to a commaspearated list of IP addresses in postgresql.conf

That line is commented out in the default conf file, when I uncomment it, and add the address, then do sudo systemctl restart postgresql the postgres processes are not running afterwards.

root@dhbpostgres:/home/johnson# ps -aux | grep postgres
root        1452  0.0  0.0   6608  2364 pts/1    S+   19:07   0:00 grep --color=auto postgres
root@dhbpostgres:/home/johnson# vi /etc/postgresql/15/main/postgresql.conf <<commented out listen_addresses
root@dhbpostgres:/home/johnson# systemctl restart postgresql
root@dhbpostgres:/home/johnson# ps -aux | grep postgres
postgres    1461  0.2  0.1 219220 30568 ?        Ss   19:08   0:00 /usr/lib/postgresql/15/bin/postgres -D /opt/data/pgdata -c config_file=/etc/postgresql/15/main/postgresql.conf

postgres    1467  0.0  0.0 220792  9444 ?        Ss   19:08   0:00 postgres: 15/main: logical replication launcher 
root        1480  0.0  0.0   6608  2276 pts/1    S+   19:08   0:00 grep --color=auto postgres

If I comment that line out as it was in the beginning, and restart, it runs.

the syslog gives me the error

Sep  6 19:06:01 dhbpostgres postgresql@15-main[1538]: 2023-09-06 19:06:01.181 GMT [1543] LOG:  syntax error in file "/etc/postgresql/15/main/postgresql.conf" line 63, near token ".206"

which corresponds to the listen_addresses line in the config file and is part of the address…

#listen_addresses = 10.128.206.109 # what IP address(es) to listen on;
# comma-separated list of addresses;
# defaults to 'localhost'; use '*' for all
# (change requires restart)


What am I missing? (postgresql 15.4 running on Ubuntu 22.04), installed via postgresql.org apt repo.

The value should be within '', so listen_addresses = '10.128.206.109' should
work just fine.

Put the entire list of addresses in quotes, e.g. 'localhost,10.128.206.109'.

The other replies have indicated how you should format the value. For 
future reference the postgresql.conf configuration docs:

https://www.postgresql.org/docs/current/runtime-config.html

tell you what is expected. In this case:

https://www.postgresql.org/docs/current/runtime-config-connection.html#RUNTIME-CONFIG-CONNECTION-SETTINGS

listen_addresses (string)

vs

port (integer)
