How to Install ACP Admin on OpenBSD

ACP Admin is a web-based administration tool used to manage Linux and UNIX servers. In this tutorial, we will be installing ACP Admin on OpenBSD.

Prerequisites

Before installing ACP Admin, make sure that you have the following:

OpenBSD installed.
Internet connection.
Root privileges.

Step 1: Install Required Packages

ACP Admin requires several packages to be installed on OpenBSD. To install these packages, run the following command:

$ sudo pkg_add sudo ruby ruby-bundler lite-cli lighttpd mariadb-server mariadb-client

Step 2: Install ACP Admin

Download and extract the ACP Admin package from the official website.
Copy the extracted folder to /usr/local.
Change the ownership of the ACP Admin folder by running the following command:
```
$ sudo chown -R www:www /usr/local/acp-admin
```
Navigate to the ACP Admin root folder and install the required gems by running the following command:
```
$ sudo bundle install
```

Step 3: Configure Lighttpd

Lighttpd is a web server used to serve web applications. To configure it for ACP Admin, follow these steps:

Navigate to the lighttpd configuration folder by running:
```
$ cd /etc/lighttpd
```
Create a new file named acp-admin.conf inside the conf.d folder:
```
$ sudo touch conf.d/acp-admin.conf
```

Open the acp-admin.conf file and add the following configuration:

server.modules += ("mod_proxy", "mod_proxy_http", "mod_proxy_fastcgi",
                   "mod_rewrite", "mod_redirect")
proxy.debug = 0

$HTTP["host"] =~ "^admin.example.com$" {
   proxy.server = ("" => (("host" => "127.0.0.1", "port" => 3000)))
   url.rewrite-once = (
      "^(/.*\.(txt|pdf|png|jpe?g|gif|ico))$" => "$0",
      "^(/stylesheets/.+\.css)$" => "$0",
      "^(/javascripts/.+\.js)$" => "$0",
      "^(/flot/.+)$" => "$0",
      "^(/proxy)$" => "/proxy/$1",
      "^/appveyor-badge/text/([a-zA-Z0-9._-]+)/([a-zA-Z0-9._-]+)/(.+)$" => "/appveyor-badge/text/$1/$2/$3",
      "^/badge/coverage/html/([a-zA-Z0-9_-]+)$" => "/badge/coverage/html/$1/index.html",
      "^/build-status/(.*)$" => "/build-status/$1.svg",
      "^/(.*)$" => "/$1"
   )
}

Replace admin.example.com with your domain or IP address where ACP Admin will be running.

Step 4: Configure MariaDB

MariaDB is a community-developed fork of the MySQL database management system. It is used by ACP Admin to store its data. Follow these steps to configure MariaDB:

Start the MariaDB service and enable it to start on boot:
```
$ sudo rcctl start mysqld
$ sudo rcctl enable mysqld
```
Set the root password for MariaDB:
```
$ sudo mysql_secure_installation
```

Create a new database and user for ACP Admin:

$ sudo mysql -u root -p
MariaDB> CREATE DATABASE acpadmin_db;
MariaDB> GRANT ALL PRIVILEGES ON acpadmin_db.* TO 'acpadmin_user'@'localhost' IDENTIFIED BY 'password';
MariaDB> FLUSH PRIVILEGES;
MariaDB> EXIT;

Replace acpadmin_db, acpadmin_user, and password with the desired database name, username, and password, respectively.

Step 5: Start ACP Admin

Finally, start ACP Admin by running the following command:

$ sudo lighttpd -f /etc/lighttpd/lighttpd.conf -D

ACP Admin should now be accessible through a web browser by navigating to the domain or IP address you specified in the Lighttpd configuration file.

Congratulations! You have successfully installed ACP Admin on OpenBSD.
