Обсуждение: Starting PostgreSQL as an NT Service
L.S.,
I've made a simple wrapper to be able to start
the new native win32 port of PostgreSQL as an
NT Service.
One can download the sources from
http://elementals.sf.net
Best regards,

Yes...(Magnus could tell you more about this), but as I understand it, some changes to postmaster.c were required. Merlin

Follow the instructions on the page to do the install. Since you have cygwin postgres, make sure you do not have any library/path conflicts with cygwin version. (If you are only running cygwin for postgres, you might want to consider dropping cygwin environment in favor of mingw, don't be hasty tho!). This version has native ability to install as a service. Quick guide: pg_ctl register -U account_to_login_as [-P password] net start postgresql net stop postgresql etc. If you want detail logging you probably shouldn't be using the SCM yet. Manually starting with pg_ctl still (as of this writing) offers the most flexibility. p.s. the binary version is again ssl enabled as it says in the instructions. Merlin

There are couple of gotchas:
1. The account that is starting postgresql can not have administrator
privileges. This is a safety issue...works the same on unix.
2. The account starting postgresql must have 'log on as a service'
privilege. More about this in a sec.
3. Make sure the postgresql NT user (in your case: 'postgres') has
permissions to the data folder. Add this user to the folder and make
sure you apply the permissions to the subfolders. It goes without
saying that the data folder should *not* be shared to the outside world
in any way.
4. Make sure you ran initdb previous to attempting to resister server.
You can omit the -U parameter to pg_ctl and play around with the
accounts with the service directly (select log on as... in service
properties). It's easier there because you get more detailed error
information and you don't have to keep re-registering the server.

I registerd the service using the bat file:
d:
cd pgsql\bin
"pg_ctl.exe" unregister -N postgres
"d:\pgsql\bin\pg_ctl.exe" register -N postgres -U postgres -P
elephant5432 -D d:\pgsql\data"
net start postgres
I got :
The description for Event ID ( 0 ) in Source ( PostgreSQL ) cannot be found.
The local computer may not have the necessary registry information or
message DLL files to display messages from a remote computer. The following
information is part of the event: Unable to find exe.
message written to event viewer.
d:\pgsql\bin is in the path.
Path to executable in the service manager is:
d:/pgsql/bin/pg_ctl.exe runservice -N "postgres" -D "d:/pgsql/data"
initdb finished OK, postgres is opened as unpriviledged user etc...
Why pg_ctl can't find postmaster ? Any sugestions ?

Is the your path on the system side or the user side (make sure it's on the system side for services). 2. Try setting up PGDATA (in system env. variables) to avoid use of -D option. 3. Try logging in as user postgres and invoking postmaster directly from shell. 4. Double check NTFS permissions to 'local' folder (make sure postgres has read/execute) and to data folder (make sure postgres has full control) Merlin
running pg_ctl from postgres account gives :
D:\pgsql\bin>LOG: could not recognize system timezone, defaulting to
"Etc/GMT-1"
HINT: You can specify the correct timezone in postgresql.conf.
LOG: database system was shut down at 2004-06-30 21:42:59 Central European
Daylight Time
LOG: checkpoint record is at 0/A76CC0
LOG: redo record is at 0/A76CC0; undo record is at 0/0; shutdown TRUE
LOG: next transaction ID: 492; next OID: 17227
LOG: database system is ready
,so it is working...
loged in again, unregistered service, set the PGDATA, registered service as:
pg_ctl register -N postgres -U postgres -P elephant5432
but the error is still here :-(
I'll try to figure out what is wrong by putting some debug messages inside
"find_other_exec" function.
Regards !

1. Is the your path on the system side or the user side (make sure it's
on the system side for services).
2. Try setting up PGDATA (in system env. variables) to avoid use of -D
option.
3. Try logging in as user postgres and invoking postmaster directly from
shell.
4. Double check NTFS permissions to 'local' folder (make sure postgres
has read/execute) and to data folder (make sure postgres has full
control)

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to majordomo@postgresql.org)

Yes, it is , actually when I said: >Path to executable in the service manager is: > d:/pgsql/bin/pg_ctl.exe runservice -N "postgres" -D "d:/pgsql/data" , I ment this is what I see after opening service property dialog in MMC.

I had put 'c:\postgres\bin' and 'c:\postgres\lib' into my user path, but that meant it _wasn't_ in the user postgres's path. After logging in as postgres, I modified the PATH environment variable. And then it started up. I think the main issue is it is looking for libpq.dll which exists in lib, because it can probably find the rest of the programs that exist in bin. I have to say, the error messages aren't very helpful. But I'm glad I asked the question, because now someone might be able to find the solution by searching.
