Обсуждение: Setting up Postgresql on Linux
Hello, I originally installed postgresql as root user and now I am setting up a development environment with cvs and a java ide and tomcat. I have everything with the exception of postgresql integreted using a non-root user. THe process I am using is to logon as postges and start the database and do queries from the command line using psql. Then I logoff and logon as phil and start tomcat and my java ide. 1.Is there a better way to start the database and the web application? 2. During setup of postgresql I chown and ghgrp the /usr/local/pgsql directoy tree to postgres? 3.However my development environment(i.e. jdbc connection from my application) doesn't seem to have permission to access to all the files it needs in postgres? 4. Is is best to install postgresql as user "phil" in order to gain access for my integrated develoment environment? thanks, Phil
Take a look at your pg_hba.conf file it will be located in your data
directory, on my system (Suse) /var/lib/pgsql/data. That file sets the user
permissions of who is allowed to connect to postgres and to what databases.
In addition you need to make sure that the -i option is used to startup
postgres if you are connecting over TCP/IP. And don't forget you also have
to add the user that you are using to connect through jdbc into the user
list for the database.
Summary
1) pg_hba.conf
2) -i option to enable TCP/IP connections
3) add the jdbc user you will be connecting as to the list of users for the
database.
I hope that helps.
Keith

Subject: [GENERAL] Setting up Postgresql on Linux
Hello,
I originally installed postgresql as root user and now I am setting up a
development environment with cvs and a java ide and tomcat. I have
everything with the exception of postgresql integreted using a non-root
user.
THe process I am using is to logon as postges and start the database
and do queries from the command line using psql. Then I logoff and logon
as phil and start tomcat and my java ide.
1.Is there a better way to start the database and the web application?
2. During setup of postgresql I chown and ghgrp the /usr/local/pgsql
directoy tree to postgres?
3.However my development environment(i.e. jdbc connection from my
application) doesn't seem to have permission to access to all the files
it needs in postgres?
4. Is is best to install postgresql as user "phil" in order to gain
access for my integrated develoment environment?
thanks,
Phil

Start PostgreSQL off as service (it's probably there already but configured to start on power-up/reboot). In a production environment I set tomcat up as a service as well. In a developmemt environment, I install/run it under my user. > > 2.

It doesn't need any postgres files. It communicates via tcp/ip. Keith has already posted the config changes you need to make. > 4.

Yes, you can edit your /etc/rc.d/rc.local file and add lines something like this: su - postgres -c -- 'pg_ctl start -l $PGDATA/pgsql.log' su - httpd -c -- 'apachectl start' etc... > 2.

You just need to chown postgres.postgres whatever directory you're putting in $PGDATA. > 3.However my development environment(i.e. jdbc connection from my > application) doesn't seem to have permission to access to all the files > it needs in postgres? Someone else mentioned it, it's in pg_hba.conf. Also check your firewall installation. > 4.

If you createuser as the postgres superuser the user phil and assign him the power to add users, you make him a superuser and he will have every bit as much power as the postgres user. You might want to make two accounts, one for you as a superuser, and one for the application which is just a normal user with security to keep it in place. Enjoy!

Below are some of the steps I use when I install postgres on a new machine, check out steps 10 and 11 specifically: ---- my instructions ---- 8. Install: # cd /usr/local/postgresql-7.x # make install # make install-all-headers # cd /usr/local # chown -R postgres.postgres pgsql 9. Initialize the database as user postgres: # su - postgres # initdb -E UNICODE -D /usr/local/pgsql/data 10. Configure (as root) the PostgreSQL SysV Script. This script is useful for starting, stopping, and checking the status of PostgreSQL. # cd /usr/local/src/postgresql-7.x # cp contrib/start-scripts/linux /etc/init.d/postgres # chmod 755 /etc/init.d/postgres To have PostgreSQL start automatically when the computer boots add symbolic links from the correct /etc/rc*.d/ directories to /etc/init.d/postgres. If the normal runlevel is 3 then you really only need to add it to rc3.d: # ln -s /etc/init.d/postgres /etc/rc2.d/S85postgres # ln -s /etc/init.d/postgres /etc/rc3.d/S85postgres etc ... 11. Start PostgreSQL for the first time: # /etc/init.d/postgres start 12. Create a new db: # su - postgres $ createdb testdb $ psql testdb ----\ my instructions ---- Ron *Note:* these are taken from the book Practical Postgres by Worsley and Drake and are slightly(? can't remember, it's been so long since I made the list) modified.
