'service postgresql start' fails to start postgres service on Fedora
postgresql
Solution
Depending on your startup script, it might redirect the postmaster's output to a file. This is usually server.log in the PGDATA directory. Things I'd try:
Comment out everything in pg_hba.conf and retry. If the problem is a syntax error in that file, then commenting out the offending line will allow the server to start and then you'll be able to uncomment one at a time until you find the error.
Start postmaster directly from the shell without sending it to the background. Just run `postmaster -D <pgdata dir>` and it should spew some more helpful logs.
Problem
Newcomer to postgres here! I edited pg_hba.conf as mentioned here , but when I try to restart postgresql service, the attempt fails. Below is the command line output with all the information I could gather. ``` [root@arunpc modules]# service postgresql restart Redirecting to /bin/systemctl restart postgresql.service Job failed. See system logs and 'systemctl status' for details. [root@arunpc modules]# systemctl status postgresql.service postgresql.service - PostgreSQL database server Loaded: loaded (/lib/systemd/system/postgresql.service; enabled) Active: failed since Sun, 08 Apr 2012 21:29:06 +0530; 14s ago Process: 12228 ExecStop=/usr/bin/pg_ctl stop -D ${PGDATA} -s -m fast (code=exited, status=0/SUCCESS) Process: 12677 ExecStart=/usr/bin/pg_ctl start -D ${PGDATA} -s -o -p ${PGPORT} -w -t 300 (code=exited, status=1/FAILURE) Process: 12672 ExecStartPre=/usr/bin/postgresql-check-db-dir ${PGDATA} (code=exited, status=0/SUCCESS) Main PID: 12184 (code=exited, status=0/SUCCESS) CGroup: name=systemd:/system/postgresql.service [root@arunpc modules]# tail /var/log/messages ....

Apr 8 21:29:06 arunpc pg_ctl[12677]: pg_ctl: could not start server Apr 8 21:29:06 arunpc pg_ctl[12677]: Examine the log output. ``` FWIW, here is the configuration file (pg_hba.conf) used: ``` # TYPE DATABASE USER ADDRESS METHOD # "local" is for Unix domain socket connections only local all postgres ident sameuser local all all ident sameuser # IPv4 local connections: host all all 127.0.0.1 password # IPv6 local connections: host all all ::1 password ``` What could be the error here? It used to work fine before I made the edit (and since this was a development machine, I brilliantly didn't make any backup). I would also like to get a more detailed log output. The log message in /var/log/messages file does ask me to "Examine the log output" - which log output would this be? What other troubleshooting steps can I take? Many thanks in advance!
