Installing LedgerSMB on NixOS

LedgerSMB is a web-based accounting software designed for small and medium-sized businesses. This tutorial will guide you through how to install LedgerSMB on the latest version of NixOS.

Prerequisites

To follow this guide, you will need:

A server or a virtual machine running on top of NixOS with root-level access.
Basic knowledge of the Linux command-line.

Installation

1. Update Your System

Before you begin with the installation, it is important to ensure that your NixOS system is up-to-date. Run the following command to update your system.

sudo nix-channel --update
sudo nixos-rebuild switch

2. Install PostgreSQL Database

LedgerSMB requires a PostgreSQL database to store its data. Run the following command to install the PostgreSQL database:

sudo nix-env -i postgresql

3. Create a PostgreSQL Database

Next, create a new PostgreSQL database for LedgerSMB. Use the following command to do so:

sudo -u postgres createdb ledgersmb

4. Install Apache Web Server

LedgerSMB requires an Apache web server to function as the front-end. Use the following command to install the Apache web server:

sudo nix-env -i apacheHttpd

5. Install LedgerSMB

Now, it's time to install LedgerSMB. Use the following command to download and install the latest version of LedgerSMB:

sudo nix-env -i ledgersmb

6. Configure LedgerSMB

After the installation, you need to configure LedgerSMB to use the PostgreSQL database and the Apache web server. Follow the steps given below to configure LedgerSMB:

Edit the LedgerSMB configuration file using the following command:

sudo vi /run/current-system/sw/share/ledgersmb/ledgersmb-httpd.conf

Find the following line in the configuration file:
```
#url_base_pathname = /ledgersmb/
```
Uncomment the line by removing the "#" and replace /ledgersmb/ with the name of your subdirectory, if you’re installing LedgerSMB in a subdirectory. If you plan on using LedgerSMB on the root directory, you can leave the line as it is.
Find the following line in the configuration file:
```
dbname=ledgersmb
dbuser=ledgersmb
dbpass=ledgersmb
```
Replace the values of dbname, dbuser and dbpass with the name of the database you created earlier and the username and password that you want to use to access the database.
Save and close the configuration file.

7. Start the Apache Web Server

Finally, start the Apache web server using the following command:

sudo systemctl start apacheHttpd

Once the Apache web server is started, you can access your LedgerSMB instance on the web browser. Open your favorite web browser and enter the IP address or the domain name of your server with the subdirectory (if applicable) in the address bar.

For example, if your server's IP address is 192.168.0.10 and your subdirectory name is “ledgersmb”, then you can access your LedgerSMB instance using the following URL:

http://192.168.0.10/ledgersmb/
