Обсуждение: Please help, pgAdmin3 on Debian!
Dear All,<br /><br /> I am totally new to the PostgreSQL, and pgAdmin. I really need your help.<br /><br /> I just installedthe PostgreSQL8.1 and pgAdmin3 on a Debian system, using the apt-get install command. Apparently, the initial databaseand the user "postgres" have also been automatically created during the installation. <br /><br /> Which is good. But I've got big trouble to login to this initial db by using this auto-created username "postgres" through pgAdmin:((( The first try failed due to "Ident authentication failed", so I follow the suggestion on the pop-up window ofpgAdmin3, and changed the ident method in the pg_hba.conf file all to md5 to try again, but the database now ask me forthe password!! which I couldn't figure out the passwd so I tried to created rules in the pg_ident.conf file to map boththe ordinary user and root user od Debian system to postgres, and tried again. But still failed,:((( "ident authenticationfailed"again!!!:((( I've tried many times for all I could think and failed everytime failed:((( By the wayeach time before I try, I did "pg_ctl reload", and I could see the failure reason changed after I do reload.<br /><br/> I've sent mail to other list but no anwser back. I believe people in this group must know what's the reason andsolution. So would you please help me? So if there is auto-created password for this auto-created postgres user, pleaseanyone tell me what it is?? Also otherwise, how can I login using the "ident auth" method through pgAdmin3 (just locally)on the Debian system??<br /><br /> Any help would be greatly appreciated!!! Thank you so much for help!!!<br /><br/> leo<br /><br /><p><hr size="1" />New <a href="http://us.rd.yahoo.com/mail_us/taglines/postman4/*http://us.rd.yahoo.com/evt=39666/*http://beta.messenger.yahoo.com">Yahoo!

This should allow you to login. Then, set the password of the postgres user (alter user postgres with password 'blabla1212' ; ). Then you could change the ident method back to md5 . Adrian Maier

Please feel free to mail me directly (postgresql-8.1@packages.debian.org) for questions related to the Debian packages. It might be regarded as noise on the upstream lists. > Which is good.

As /usr/share/postgresql-common/README.Debian describes, you should first create your own database user and work with that. Then the default 'ident' authentication scheme will work, and you are free to set a password for your db user as well (so that connecting from remote computer over TCP works as well). If you really need to connect as user postgres to do administrative tasks, then the easiest solution is to set a password for the user postgres, as already mentioned in the previous reply.

I loged out of theDebian system until after 1am this very morning, and everything was fine at that time. But when I tried to login again to day today right now, I got problem. The Debian system started booting, everything goesfine until at the moment to start the postgresql server. The booting msg shows "Starting postgreSQL 8.1 database server:main", and then hung forever and not move anymore. I have to turn off the computer power to stop it! I tried tologed in via the Recovery mode and was able to login as root, but I don't know what to do about the PostgreSQL and whateverrelated system booting process at the command line mode??:(( So is there anything has been wrong with what I did yesterday? Does the password change of user postgres has some impacton the Debian system booting? Please help me out of this. The PostgreSQl 8.1 just installed, not in use at all, all has been done on it was the changeof the password of user postgres, in order to login to the initial db through pgAdmin3. Any help would be greatly appreciated!!! Thank you in advance!!! leo
