Creating a user and database in PostgreSQL

To create a database and user account for use on PostgreSQL:

root@devotion:~# su - postgres

postgres@devotion:~$ psql
psql (8.4.21)
Type "help" for help.

postgres=# create user "www-data" superuser;

postgres=# create database mydb with owner "www-data";

postgres=# \c mydb
psql (8.4.21)
You are now connected to database "mydb".
mydb=# alter user "www-data" with password 'secret';

Running Apache as ME!

On my development machine I want Apache to run under my user id so I can automatically generate files (and have permission to write them).

I configured Apache like this:

root@mercy:/etc/apache2# grep -R www-data .
./envvars:export APACHE_RUN_USER=www-data
./envvars:export APACHE_RUN_GROUP=www-data

root@mercy:/etc/apache2# vim envvars 

export APACHE_RUN_USER=jj5

root@mercy:/etc/apache2# apache2ctl graceful
/var/lock/apache2 already exists but is not a directory owned by jj5.
Please fix manually. Aborting.

root@mercy:/etc/apache2# chown jj5:jj5 /var/lock/apache2

root@mercy:/etc/apache2# apache2ctl graceful


Wait… that didn’t work. The problem was apache2ctl graceful didn’t pick up the new envvars file, this fixed it:

root@mercy:/etc/apache2# /etc/init.d/apache2 restart

Mailman check_perms

I learned about the Mailman check_perms program today. Basically it reports on permission issues with the mailman database, which is good because I was having trouble with the permissions on the mailman database. Basically email for a new list wasn’t being added to the web archive because the right permissions weren’t in place to allow the mailman process to write there. Anyway, with the help of /usr/lib/mailman/bin/check_perms and the judicious use of “chgrp -h list” and “chown -R -h www-data:list” I think I managed to fix everything up.

Update: I had a problem after applying the above changes whereby I couldn’t access the web archive for Mailman lists anymore. But… I figured out how to fix it. Basically I added the www-data to the list group with the following command (and then rebooted):

 sudo adduser www-data list
