Thank you, Cesar, for your fast reply :)

The error.log says "Error: return: failed to redirect 'GET /global/file-not-found.html': exceeded recursion limit of 3"

Have a good day.

Hi Irma...

That just means there was an error rendering the error page, which invoked the error page, which invoked the error page, whi STOP!

Oh, sorry...

But that's how it happened, including the STOP.

Hi Jim.
I already fix the problem: I delete everything and start a new installation. All is running! Thank God.
Have a good day.

I'm attempting to run through the tutorial and I'm stuck with the following command. What am I missing? I'm using the latest software of openacs, postgresql, and naviserver.

sudo psql -d openacs -U wwww-data
psql: FATAL: Peer authentication failed for user "wwww-data"

Dear Christopher,

this error message comes from PostgreSQL and tells you that the database does not know about a user "wwww-data". When you installed OpenACS with the default values of the install-ns and install-oacs scripts, then the created postgres user is named "nsadmin", the database is "oacs-5-8".

In this setup, sudo psql -d oacs-5-8 -U nsadmin should work.

Hello Gustaf,

I was able to get the command to work if I used "psql -d oacs-5-8 -U postgres" When I use sudo is asks for a password and it isn't the root password. After using the command I tried using insert into but got an error message. I have created a file in my package/todo/sql/postgres/ based on the tutorial.

oacs-5-8=# insert into todo_item values(acs_object_id_seq.nextval, 'My first item', 'My first item description', 'p', 568);
ERROR: relation "todo_item" does not exist
LINE 1: insert into todo_item values(acs_object_id_seq.nextval, 'My ...

Christopher, see page 48 (and just prior) of the tutorial. The error translates to: table "todo_item" doesn't exist.
cheers

Christopher,

when the install-oacs script runs successfully, it creates the user 'nsadmin'; otherwise, other things might be broken as well. To check, which users are defined in your postgres installations, use 

   %psql -U postgres 
   psql (9.3.5)
   Type "help" for help.

   postgres=# \du
in order to see, what databases are defined, use 
   postgres=# \l

Hello Gustaf,

This is what I got when I enter the commands:

postgres=# \du

postgres | Superuser, Create role, Create DB, Replication | {}

postgres=# \l

Christopher,

This looks correct. Therefore, the cmd as i wrote will work. maybe you were struggling with sudo. For setup of sudo, see e.g. [1]. One can setup sudo such it asks you once in a session for your password, or to ask for certain users never for a password, etc.

Hello Gustaf,

I'm using ubuntu 14.04 LT now. Is there any location where I can find the final version of the tutorial code? I have copied all the code but continue to get error messages.

Dear Christopher,

i've never read the tutorial, this was contributed from the people in Guatemala. What kind of errors do you get?

Hello Gustaf,

I'm getting errors that the database item doesn't exist. I'm trying to run through the tutorial to see how everything works before giving the system to a developer. I can at least complete the hello World! example.

Database operation "select" failed (exception ERROR, "ERROR: relation "todo_item" does not exist
LINE 8: from todo_item
^
")

ERROR: relation "todo_item" does not exist
