    Hallo,

    ich habe heute bei Ubuntu 8.04 via apt PostgreSQL installiert. An sich läuft die Datenbank auch, und ich kann *eigentlich* auch zur Datenbank verbinden. Aber nur, wenn ich vorher auf den passenden User wechsle.
    Code:
    su <root-PW>
    su postgres
    psql
    
    bzw.
    Code:
    su <root-PW>
    su wbloguser
    psql
    
    Wenn ich allerdings von meinem "normalen" Benutzer aus als einer der obigen Benutzer darauf zugreifen will, funktioniert's nicht mehr:

    Code:
     psql -U postgres
    psql: FATAL:  Ident-Authentifizierung für Benutzer »postgres« fehlgeschlagen
    
    Dasselbe, wenn ich noch ein -h localhost oder ein -h 127.0.0.1 mit angebe, mit -W und ohne -W (zur erzwungenen Passwortabfrage).

    Meine entsprechenden configs schauen bisher so aus (leich abgeänderte Defaultwerte mit ziemlich nah an den Beispielen aus der PSQL-Doku übernommenen Werten):

    Code:
    #/etc/postgresql/8.2/main/pg_hba.conf
    
    (... Die Eingangskommentare hab ich abgeschnitten ...)
    
    # Database administrative login by UNIX sockets
    local   all         postgres                          ident sameuser
    
    # TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD
    
    # "local" is for Unix domain socket connections only
    local   all         all                               ident omicron
    # IPv4 local connections:
    host    all         all         127.0.0.1/32          ident omicron
    # IPv6 local connections:
    host    all         all         ::1/128               ident omicron

    # PostgreSQL configuration file

    #
    # This file consists of lines of the form:
    #
    #   name = value
    #
    # (The '=' is optional.)  White space may be used.  Comments are introduced
    # with '#' anywhere on a line.  The complete list of option names and
    # allowed values can be found in the PostgreSQL documentation.  The
    # commented-out settings shown in this file represent the default values.
    #
    # Please note that re-commenting a setting is NOT sufficient to revert it
    # to the default value, unless you restart the server.
    #
    # Any option can also be given as a command line switch to the server,
    # e.g., 'postgres -c log_connections=on'.  Some options can be changed at
    # run-time with the 'SET' SQL command.
    #
    # This file is read on server startup and when the server receives a
    # SIGHUP.  If you edit the file on a running system, you have to SIGHUP the
    # server for the changes to take effect, or use "pg_ctl reload". Some
    # settings, which are marked below, require a server shutdown and restart
    # to take effect.

    Weiß jemand, was ich falsch mache / übersehen habe? Also, ich möchte mich als (Linux-)User alex mittels
    Code:
    psql -U wbloguser [-W] 
    zur PostgreSQL-DB verbinden.

    An sich würd ich schon gerne psql nutzen, weil's, im Gegensatz zu MySQL nen on delete/update set default kann/können soll ;) Aber wenn ich nur mit Benutzern zu der DB verbinden kann, nachdem ich auf den richtigen geswitcht bin, fänd ich des bissl nervig...

    Wäre cool, wenn mir bitte jemand weiterhelfen kann :) Falls Info's fehlen, liefer ich die gerne nach!

    Welche Authentifizierungsmethoden sind in der '/etc/postgresql/8.2/main/pg_hba.conf' freigeschaltet?

    Du meinst die Datei, die er oben gepostet hat? *g*
    Sorry, meine postgres Zeit ist etwas länger her, aber es zentriert sich um die pg_hba.conf und es ist definitv möglich, mehr weiss ich aber auch nimmer...

    Ah, hm, ich glaub, ich hab's jetzt funktioniert's ein Stückerl mehr (Ich kann jetzt von der Konsole aus als normaler user und als www-data mit dem Datenbankuser wbloguser auf die gewünschte Datenbank zugreifen).

    Dank der genervten Version von "planvollem Vorgehen" :devil: weiß ich jetzt aber nicht mehr so recht, was ich heute noch großartig geändert hab, was ich nicht gestern schon erfolglos ausprobiert habe ... Jedenfalls schaut's jetzt so aus:

    Code:
    # pg_ident.conf, wieder ohne die Eingangskommentare:
    
    # MAPNAME     IDENT-USERNAME    PG-USERNAME
    admin         alex              postgres
    admin         root              postgres
    admin         postgres          postgres
    wblogapp      alex              wbloguser
    wblogapp      www-data          wbloguser
    
    Code:
    #pg_hba.conf, auch wieder ohne Eingangskommentare
    
    # Database administrative login by UNIX sockets
    local   all         postgres                          ident admin
    local   wblog       wbloguser                         ident wblogapp
    
    # TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD
    
    # "local" is for Unix domain socket connections only
    local   all         all                               ident admin
    local   wblog       wbloguser                         ident wblogapp
    # IPv4 local connections:
    host    all         all         127.0.0.1/32          ident admin
    host    wblog       wbloguser   127.0.0.1/32          ident wblogapp
    # IPv6 local connections:
    host    all         all         ::1/128               ident admin
    host    wblog       wbloguser   ::1/128               ident wblogapp
    
    Jetzt würd mich nur noch interessieren, warum der Zugriff via PHP-Script nicht passt (Lt. Apache2-Config sollte derselbe als www-data rennen....).
    PHP:
    $dbconn3 pg_connect("host=localhost port=5432 dbname=wblog user=wbloguser password=korrektesGeheimesPWD");
    =>
    Code:
    [B]Warning[/B]:  pg_connect() [[URL="http://localhost/function.pg-connect"]function.pg-connect[/URL]]: Unable to connect to PostgreSQL server: FATAL:  Ident-Authentifizierung für Benutzer »wbloguser« fehlgeschlagen in [B]/var/www/index.php[/B] on line [B]3[/B]
    Hmmmm.... Wo ich grad schreib und nebenbei weiter rumspiel merk ich grad, das zwar nicht
    Code:
    (16:04:23) psql -h localhost -U wbloguser wblog
    psql: FATAL:  Ident-Authentifizierung für Benutzer »wbloguser« fehlgeschlagen
    {-alex-|-asterix-} => [~]
    (16:04:31) psql -h 127.0.0.1 -U wbloguser wblog
    psql: FATAL:  Ident-Authentifizierung für Benutzer »wbloguser« fehlgeschlagen
    
    funktioniert, aber

    Code:
    {-alex-|-asterix-} => [~]
    (16:06:28) psql -U wbloguser wblog
    Dies ist psql 8.3.3, das interaktive PostgreSQL-Terminal.
    
    Ich dachte, mit den IPv4 / IPv6 - Zeilen kann ich auch via localhost und nicht nur via /var/run/postgresql auf die DB verbinden ?( ? PSQL jedenfalls lauscht laut nmap localhost schon auf Port 5432. Falls ich, wie sonst wohl gerne vorgeschlagen, die tcpip_socket = on in die postgresql.conf eintrage, wird gemeckert, das PSQL diese Anweisung nicht kennt...

    /Edit: Hm, mit trust funktioniert's schon, aber mit ident nicht. Was muss man da bei ident noch so abändern, das ist hier die Preisfrage....?
    .
    .
    .
    EDIT (autom. Beitragszusammenführung) :
    .

    Naja, ich hab im Skript mal den Connection-String abgeändert und die "host=" Angabe weggelassen. Damit funktioniert's jetzt (so, wie ich's im Moment brauch.:)) Ob des so gut oder eher suboptimal eingestellt ist (Sicherheits- und "schönheits"technisch), darüber mach ich mich dann später noch mal'n Kopf :think:
