If you are going to use apache, you can
edit the file /etc/httpd/conf/extra/httpd-davical.conf in your apache
config if you want to have a vhost other than "localhost".

Add the following in /etc/httpd/conf/httpd.conf at the end:

Include conf/extra/httpd-davical.conf

Also make sure to uncomment the following in /etc/php/php.ini:
extension=gettext.so
extension=iconv.so
extension=pdo_pgsql.so
extension=pgsql.so

Restart apache: sudo apachectl restart

Rename /etc/davical/localhost-conf.php to xxx-conf.php if you named your
vhost in httpd-davical.conf xxx and edit the file to your needs

If you are installing postgresql for the first time start
it first: sudo rc.d start postgresql
This will create /var/lib/postgres/data/pg_hba.conf

Now edit this file to add the following
at the end:

local   davical davical_dba trust
local   davical davical_app trust

Restart postgresql: sudo rc.d restart postgresql

Then create the davical database: first become root, then become user
postgres. For example:

sudo su
su - postgres

Then, you are ready to execute
/srv/http/davical/dba/create-database.sh
as the user postgres.

IMPORTANT!
Write down the password for
the admin user that is displayed

Logout of postgres user and root user after you have written down
the admin user and password using:

logout
logout

Use your browser to navigate to http://localhost/davical or the vhost
you have edited in httpd-davical.conf

Login using admin and the password that you written down above.
