Обсуждение: postgres installed via rpms -can't run postmaster or postgres
Hi, I am relatively new to Linux and just installed postgres via rpms.
I think. However, I can't for the life of me figure out how to start up
postmaster or psql.
psql - I keep getting the following error when running psql...
"psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.1234"?"
How do I find out if the server is running locally and accepting
connections on Unix domain socket?
postmaster - I keep getting the following error when trying to start
postmaster...
"postmaster does not know where to find the database system data.
You must specify the directory that contains the database system
either by specifying the -D invocation option or by setting the
PGDATA environment variable."
Okay, set it to what? man and postgres docs are of little help. Any
help is much appreciated. Following are the rpm's I ran
redhat-install-packages on. I got them from a mirror off
postgresQl.org...
ostgresql-7.3-2PGDG.i386.rpm
postgresql-python-7.3-2PGDG.i386.rpm
postgresql-contrib-7.3-2PGDG.i386.rpm
postgresql-server-7.3-2PGDG.i386.rpm
postgresql-devel-7.3-2PGDG.i386.rpm
postgresql-docs-7.3-2PGDG.i386.rpm
postgresql-jdbc-7.3-2PGDG.i386.rpm
postgresql-libs-7.3-2PGDG.i386.rpm
postgresql-pl-7.3-2PGDG.i386.rpm
Oh, and another thing I'm confused about is... I tried to install these
in /usr/local/bin, that's where the rpms are, but they wound up in
/usr/lib. Any idea why that might be? I rpm'd from /usr/local/bin
many thx

Great! I very much appreciate your help. I'm unclear on what I need to set PGDATA or the -D option with in order to run postmaster. Any idea? Here is what I'm trying and the errors given... $ postmaster "postmaster does not know where to find the database system data. You must specify the directory that contains the database system either by specifying the -D invocation option or by setting the PGDATA environment variable." So I tried $ postmaster -D /etc/rc.d/init.d" "FATAL: data directory /etc/rc.d/init.d has group or world access; permissions should be u=rwx (0700)" So I changed the permissions but that didn't work either. again, many thx Eric On Sat, 2003-10-18 at 06:21, Bruno LEVEQUE wrote: > With the postgresql-server-7.3-2PGDG.i386.rpm, you have installed a > file etc/rc.d/init.d/postgresql, > if you run it like postgresql start, you must start postmaster and so > you can connect. > (I am not a specialist of RH so may be there is other thinks to know) > > Bruno > > > Eric M.

The line you need with postmaster should be like : postmaster -i -D /PATH/WHERE/FIND/DATA/FILES -S The /PATH/WHERE/FIND/DATA/FILES must be /var/lib/pgsql/data/ (or /var/lib/pgsql) The -i is for allowing clients to connect via TCP/IP The -S is fot separating postmaster of the console launching it.

I hope you didn't do most of it, since the RPM installation does most of the hard things for you. I know this because I built the RPMs. But I digress. The RPM's are intended to make things simpler. First, though, you need to get a newer version than 7.3-2. You really want to download the 7.3.4 RPMs, since 7.3.4 has substantial bugfixes. To get a running postgresql system with the RPMs, after installing the RPMs (assuming you have postgresql-server installed), while you are still root (do not su to postgres for this step, as the script you are about to run does that for you), run '/sbin/service postgresql start'. The 'service' command (located in /sbin) on Red Hat Linux is the control program to start, stop, and otherwise signal system processes. It invokes the /etc/rc.d/init.d/postgresql script packaged with the postgresql-server RPM. The script automatically performs the proper initdb functions and starts the postmaster as user postgres (the user and group named postgres were created during the installation of the postgresql-server RPM by the RPM's post installation script). Once the postmaster is running (use the command 'ps ax|grep postmaster' to see if the postmaster is running), you can su to the postgres user (from root only, since you can't directly log in as that user, unless you set its password) and run the commands you need to run. > Oh, and another thing I'm confused about is... I tried to install these > in /usr/local/bin, that's where the rpms are, but they wound up in > /usr/lib. Any idea why that might be? I rpm'd from /usr/local/bin The directory in which you execute the rpm command has nothing to do with where the rpm is installed. The locations for each of the files in the RPM itself is set by the packager (in this case, me), and isn't selectable by the installer, unless the packager has made the package relocatable (which the postgresql RPMs aren't). I am, however, somewhat dismayed by the amount of misinformation you already have received. My apologies for not replying sooner. So, in summary, to get a running PostgreSQL installation with the RPM's (assuming PostgreSQL is not already installed): rpm -i postgresql*7.3.4*.rpm /sbin/service postgresql start su - postgres createdb ....... createuser ...... psql ..... ......
