Hi,
Postgres was installed through a repo with yum install.

So did you disable the start/stop scripts that the package installed?

I will try to run it with another type.
Regards
Marian

Hi Adrain,
Thanks for your reply.


How was Postgres installed on this machine?

Have you tried the script from the docs?


My script looks like this:

I am no systemd expert, still the Type=forking does not seem right to me.

# cat /usr/lib/systemd/system/postgresql-9.6.pg-tstxxx.service
[Unit]
Description=postgresql_pg-tstxxx
After=syslog.target
After=network.target
[Service]
Type=forking
User=postgresql
Group=postgresqlg
Environment=PGDATA=/data/pg-tstxxx/data-01/
# Run ExecStartPre with root-permissions
PermissionsStartOnly=true
ExecStartPre=/bin/chown postgresql:postgresqlgroup /var/run/postgresql
ExecStart=/usr/pgsql-9.6/bin/pg_ctl start -D ${PGDATA}
ExecStop=/usr/pgsql-9.6/bin/pg_ctl stop -D ${PGDATA} -s -m fast
ExecReload=/usr/pgsql-9.6/bin/pg_ctl reload -D ${PGDATA} -s
Restart=on-failure
KillMode=control-group
ExecStop=/bin/kill -SIGTERM $MAINPID
RestartSec=10s
[Install]
WantedBy=multi-user.target
thanks in advance.
regards,
Marian

    How did you install Postgres on the machine?

    Did you use the example at the above link or did you write your own?
    If you wrote your own can you show it?
