Installing LedgerSMB 1.2 


This document contains information on how to install LedgerSMB.  We recommend
that the reader start by reading the section on manual installation and then
start by trying the automated means mentioned later.

Also this document assumes that the reader is already familiar with the release
notes.  If you have not already done so, please read the release_notes file in
the doc/ directory.

DISTRO AND OS-SPECIFIC NOTES:
===============================================================================
Debian users should read README.debian


MANUAL INSTALL:
===============================================================================

1)  Untar in desired location (for example, /usr/local/).

2)  Decide where to put the user/session management tables.  In general, we
recommend as follows:

  a)  Single dataset installations should use the user tables in the dataset.

  b)  Multicompany installations should use user tables in a separate dataset
      from any accounting data.


3) Create a admin database role named 'ledgersmb':

    bash$ createuser --no-superuser --createdb --no-createrole -U postgres
     --pwprompt --encrypted ledgersmb


4) Create a central user database database, owned by admin role:

    bash$ createdb -U ledgersmb -O ledgersmb ledgersmb


5) Run the included SQL commands to configure the central user database:
   (ledgerpath) is wherever you untarred the file.  If you untarred to 
   /usr/local/ then it will be /usr/local/ledger-smb.

    bash$ psql -U ledgersmb -d ledgersmb -f (ledgerpath)/sql/Pg-central.sql


6) Update your admin password in the central user database
    (change MYPASSWORD to your preferred administrative password).

    bash$ psql -U ledgersmb -d ledgersmb

    ledgersmb=> UPDATE users_conf SET password = md5('MYPASSWORD') WHERE id = 1;

7) Quit the interactive SQL console:

    ledgersmb=> \q

7b) If you want to store the company information in the same database, run the 
    following command:

    bash$ createlang -U postgres -d ledgersmb plpgsql;

    If not, then you can skip to step 8.

8)  Edit the ledger-smb.conf file as appropriate.

  a)  Copy the ledger-smb.conf.default to ledger-smb.conf
  b)  Make sure to set the section under [globaldbh] to point to the database 
      you imported Pg-central into.

9)  Add configuration to Apache:
    bash$ sh configure_apache.sh

10) Check Dependencies

The Build.PL script can be used to test for unmet dependencies and run other
tests.  It doesn't install anything yet, but it will tell you what you are 
missing.  To check for dependencies, run "perl Build.PL" from the command line.
Missing dependencies can generally be installed via a Linux distributor's
package manager or by CPAN. (Build.PL itself uses Module::Build, which is
available in packages like perl-Module-Build or libmodule-build-perl.)

Once this is done and dependencies are satisfied, you can check to see whether
the installation nominally works by running "./Build test" from the command
line.  The test suites currently check to make sure all the perl modules load
and that a number of numeric tests are passed.

Dependencies which are recommended are needed only for specific functionality
and may not be required in all circumstances.  These include:

  * Net::TCLink for credit card processing in a POS environment
  * Parse::RecDescent for the CLI script host

11) Restart Apache (instructions may vary with your Linux distro or operating
    system).

12) Create Datasets and Users:
   Visit http://hostname/ledger-smb/admin.pl, login with MYPASSWORD, 
   Create datasets with user ledgersmb, superuser postgres
      (omit the superuser if creating inside the database you imported 
      Pg-central into).
   Create users pointing to datasets.

Congratulations, you have manually installed LedgerSMB 1.2.


FTP INSTALLATION:
============================================================================

If you control the server and have shell access, the
instructions above are preferred over those given here.
instead of those given here.  This is simply a set of 
notes for those who must install on a shared server.

If you do not have access to the server's configuration
files install LedgerSMB in userspace by ftp'ing all the
files to your server.

a) untar ledger-smb in your private_html directory

b) turn on script execution for the folder ledger-smb
You can control this with an .htaccess file

  Options +ExecCGI
  DirectoryIndex login.pl

c) protect the users directory with an .htpasswd file

order allow,deny
deny from all

d) protect the templates directory with an .htpasswd file

order allow,deny
deny from all

e) set up your PostgreSQL database and the tables.  The basic
procedure is specified above.

You will most likely only have access to PostgreSQL with
some other tools like pgadmin.


TROUBLESHOOTING
===========================================================================

Error:  Access Denied in admin.pl

Likely causes:

1)  The password entered may not match the password set in step 6.  You can 
    repreat that step prior to the creation of user accounts as often as you 
    wish.

    After the creation of user accounts, the commant to reset the admin password
    is:
    UPDATE users_conf SET password=mp5('MYPASSWORD') WHERE id = 
        (select id FROM user WHERE username = 'admin');

    Of course, substitute 'MYPASSWORD' for your chosen password.

2)  The central database may have been created with a different user than you 
    are using for the connection and you may not have permission to access the
    required database entities.  To correct this, assuming that the desired 
    database username is ledgersmb, the following commands from psql:

      GRANT ALL ON users TO ledgersmb;
      GRANT ALL ON users_id_seq TO ledgersmb;
      GRANT ALL ON users_conf TO ledgersmb;
      GRANT ALL ON session TO ledgersmb;
      GRANT ALL ON session_session_id_seq TO ledgersmb;

--------------------------------------------------

Error: "No GlobalDBH Configured or Could not Connect"

LedgerSMB 1.2 uses a dedicated connection to the central database for user 
authentication.  When the attempt to connect to that database fails, the error
message above is displayed.   In this case, check the following parameters 
under the [globaldbh] of the ledger-smb.conf file.

1)  DBUserName should match the database user you imported Pg-central as (if
    you followed the instructions above, that would be ledgersmb).

2)  DBPassword needs to match the database password to used to connect to.

You can test the above causes by running (from the command line):
bash$ psql -U [DBUserName]
password: [DBPassword]

When you enter the password, it will not show up on the screen.

The other line that you should pay attention to is the DBConnect line.  
Parameters in the form of name=value need to match those for your host.  The 
following parameters need to be set correctly in that line:

dbname=ledgersmb (or whatever database you imported Pg-Central.sql into).
host=localhost (don't change this unless you know what you are doing!)
port=5432      (don't change this unless you know what you are doing!)

The full line should then be something like:
DBConnect: dbi:Pg:dbname=ledgersmb;host=localhost;port=5432
