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 OpenBSD users, please consult the README.OpenBSD For Unix systems, '$' signifies the bash prompt, '=>' the psql prompt. MANUAL INSTALL ============== 1) Untar in desired location (for example, /usr/local/ledger-smb, refered to as LEDGERPATH for the remainder of this INSTALL file). LedgerSMB files should be owned by the apache user, apache:apache on many systems. 2) Create a postgresql admin database role, by convention named 'ledgersmb': $ createuser --no-superuser --createdb --no-createrole \ -U postgres --pwprompt --encrypted ledgersmb (\ is a bash line continuation character, this is a single command) The prompted password (referred to as MYROLEPASSWORD) will later be used in the DBConnect: string in the configuration file 'ledger-smb.conf' The equivalent SQL statement to create the ledgersmb role is: => CREATE ROLE ledgersmb LOGIN PASSWORD 'MYROLEPASSWORD' NOINHERIT CREATEDB; Further commands and database interaction should be conducted using the new LedgerSMB admin role 'ledgersmb'. 3) Create a central user database, owned by the LedgerSMB admin role, 'ledgersmb': $ createdb -U ledgersmb -O ledgersmb ledgersmb The equivalent SQL statement is: => CREATE DATABASE ledgersmb WITH ENCODING='SQL_ASCII' OWNER=ledgersmb; 4) On the database that will store your user and session information, run the included Pg-central.sql SQL commands to configure the user and session tables and functions: $ psql -U ledgersmb -d ledgersmb -f LEDGERPATH/sql/Pg-central.sql (LEDGERPATH is in the location you expanded the release tarball file. If you untarred in '/usr/local' then LEDGERPATH will be '/usr/local/ledger-smb'). NOTE: LedgerSMB's preferred configuration is to store the user and session management tables in a separate database from the company databases (aka 'datasets', created in admin.pl). If you are already working with or prefer to have your user and session tables in one company dataset, see further information in the manual. You must have PLPGSQL installed in the dataset as well. However that is beyond the scope of these instructions. 5) The SQL commands in step 4) created an LedgerSMB-managed admin user, e.g. a row in the users and users_conf table. You must now update the 'admin' user's password in users_conf from the default password. $ psql -U ledgersmb -d ledgersmb ledgersmb=> UPDATE users_conf SET password = md5('MYPASSWORD') WHERE id = 1; (Change MYPASSWORD to your preferred administrative password, which is separate, but can be the same spelling as MYROLEPASSWORD). ledgersmb=> \q 6) Edit the LEDGERPATH/ledger-smb.conf file: a) Copy 'ledger-smb.conf.default' to 'ledger-smb.conf' b) Make sure to set the section under [globaldbh] to point to the central user and session database, using password MYROLEPASSWORD: [globaldb] DBConnect: dbi:Pg:dbname=ledgersmb;host=localhost;port=5432 DBUserName: ledgersmb DBPassword: MYROLEPASSWORD 7) Add configuration to Apache: $ sh configure_apache.sh 8) 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 Missing dependencies can generally be installed via a Linux distribution'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 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 9) Restart Apache (instructions vary with your Linux distro or operating system). Create Datasets and Users ========================= 1) Create Datasets: Browse to: http://hostname/ledger-smb/admin.pl login with 'MYPASSWORD' Create dataset(s) with: User: ledgersmb Password: MYPASSWORD Superuser: postgres Password: (postgres password) Create one dataset (a postgresql datatabase) for each separate company which will use LedgerSMB for accounting, e.g.: ledgeracme ledgerbigco (...) 1) Create User(s) pointing to specific datasets: Browse to: http://hostname/ledger-smb/admin.pl login with 'MYPASSWORD' Create user(s) pointing to a specific dataset (ledgeracme, etc.) with database login information: User: ledgersmb Password: MYPASSWORD 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. 1) Untar ledger-smb in your private_html directory. 2) turn on script execution for the folder ledger-smb. You can control this with an .htaccess file: Options +ExecCGI DirectoryIndex login.pl 3) Protect the users directory with an .htpasswd file: order allow,deny deny from all 4) Protect the templates directory with an .htpasswd file: order allow,deny deny from all 5) Set up your PostgreSQL database and the tables. The 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 Manual Install step 5). You can repreat that step as often as you need to get login to admin.pl working, but in case your 'admin' user is not id=1, try using the expanded version of the SQL: ledgersmb==> UPDATE users_conf SET password=mp5('MYPASSWORD') WHERE id = (SELECT id FROM user WHERE username = 'admin'); (Substitute 'MYPASSWORD' for your chosen password). 2) The central database may have been created with a different postgres user (role) than you are using for the connection. In this case, you may not have permission to access the required database entities. To correct this, assuming that the admin database role is ledgersmb, issue the following commands from psql: ledgersmb==> GRANT ALL ON users TO ledgersmb; ledgersmb==> GRANT ALL ON users_id_seq TO ledgersmb; ledgersmb==> GRANT ALL ON users_conf TO ledgersmb; ledgersmb==> GRANT ALL ON session TO ledgersmb; 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): $ 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 (the database you imported Pg-Central.sql into). host=localhost (don't change unless you know what you are doing!) port=5432 (don't change unless you know what you are doing!) The full line should then be something like: DBConnect: dbi:Pg:dbname=ledgersmb;host=localhost;port=5432 And that section of ledger-smb.conf looks like: [globaldb] DBConnect: dbi:Pg:dbname=ledgersmb;host=localhost;port=5432 DBUserName: ledgersmb DBPassword: MYROLEPASSWORD
