How to Install Poweradmin on NetBSD

In this tutorial, we will go through the installation process of Poweradmin on NetBSD operating system.

Prerequisites

Before starting the installation process, make sure your system meets the following requirements:

NetBSD operating system installed
Access to the root user account

Steps

Update the package repository:
```
# pkgin update
```

Install the required packages:

# pkgin install php php-json php-pdo php-pdo_mysql php-xml php-gd php-mbstring lighttpd php-cgi mysql-server

Start the MySQL server with the following command:
```
# /usr/pkg/bin/mysqld_safe &
```

Create a new MySQL database and user for Poweradmin:

# mysql -u root -p
mysql> CREATE DATABASE poweradmin;
mysql> GRANT ALL PRIVILEGES ON poweradmin.* TO 'poweradmin_user'@'localhost' IDENTIFIED BY 'password';
mysql> FLUSH PRIVILEGES;

Note: Replace 'password' with a strong and secure password.

Download the Poweradmin tarball using the following command:

# wget https://github.com/poweradmin/poweradmin/archive/v2.1.7.tar.gz

Extract the tarball:
```
# tar -xzf v2.1.7.tar.gz
```
Move the extracted folder to the lighttpd document root folder:
```
# mv poweradmin-2.1.7 /usr/pkg/share/lighttpd/
```

Rename the Poweradmin configuration file:

# mv /usr/pkg/share/lighttpd/poweradmin-2.1.7/inc/config-me.inc.php /usr/pkg/share/lighttpd/poweradmin-2.1.7/inc/config.inc.php

Edit the Poweradmin configuration file and update the database credentials:

# vi /usr/pkg/share/lighttpd/poweradmin-2.1.7/inc/config.inc.php

Update the following lines with the MySQL database details:

$db_host            = 'localhost';
$db_user            = 'poweradmin_user';
$db_pass            = 'password';
$db_name            = 'poweradmin';

Change the ownership and permissions of the Poweradmin folder:

# chown -R www /usr/pkg/share/lighttpd/poweradmin-2.1.7/
# chmod -R 775 /usr/pkg/share/lighttpd/poweradmin-2.1.7/

Configure lighttpd to serve the Poweradmin folder:

# vi /usr/pkg/etc/lighttpd/lighttpd.conf

Add the following lines to the file:

server.document-root = "/usr/pkg/share/lighttpd/poweradmin-2.1.7"
server.modules += ( "mod_cgi" )
cgi.assign = (
    ".php" => "/usr/pkg/bin/php-cgi"
)
server.errorlog = "/var/log/lighttpd/error.log"
accesslog.filename = "/var/log/lighttpd/access.log"

Restart the lighttpd web server:
```
# /etc/rc.d/lighttpd restart
```
Access Poweradmin by navigating to http:/// and logging in with the administrator credentials. The default username is 'admin' and password is 'password'.

Congratulations, you have successfully installed and configured Poweradmin on NetBSD operating system.
