Thanks, adrian, but I have check the pgstartup.log, I got the following messages: ..... creating information schema ... ok vacuuming database template1 ... ok copying template1 to template0 ... ok copying template1 to postgres ... ok
Success. You can now start the database server using: /usr/bin/postgres -D /var/lib/pgsql/data or /usr/bin/pg_ctl -D /var/lib/pgsql/data -l logfile start runuser: cannot set groups: Operation not permitted I tried this: -bash-4.1$ /usr/bin/pg_ctl -D /var/lib/pgsql/data -l logfile start server starting -bash-4.1$ ps -ef |grep postgres root 2904 2585 0 22:59 pts/1 00:00:00 su - postgres postgres 2905 2904 0 22:59 pts/1 00:00:00 -bash postgres 2946 2905 7 23:00 pts/1 00:00:00 ps -ef postgres 2947 2905 0 23:00 pts/1 00:00:00 grep postgres It reported that I have started the server but that doesn't work, I think there must be somebody has the same problem with me. Any suggestions.
