How to Install Paste on Fedora CoreOS Latest

Introduction

Paste is an open-source web application that allows users to share code snippets and texts online. This tutorial provides steps to install the Paste web application on the latest version of Fedora CoreOS.

Prerequisites

Before you can install Paste on Fedora CoreOS Latest, you need to ensure that you have the following:

• A Fedora CoreOS Latest installation or instance
• A user account with sudo privileges

Step 1: Install Required Dependencies

The first step is to install the dependencies required for running Paste. You can do this from the command line by running the following command:

sudo dnf install gcc php php-fpm php-json php-mbstring php-opcache php-pgsql postgresql-libs

Step 2: Download and Extract the Paste Source Code

Next, you need to download the Paste source code from its official website by running the following command:

curl -L https://github.com/phpaste/phpaste/archive/master.zip -o phpaste.zip

Once the download process is complete, extract the downloaded zip file using the following command:

unzip phpaste.zip -d phpaste

Step 3: Configure Paste

After extracting the Paste source code, you need to configure it. To do this, navigate to the phpaste directory using the following command:

cd phpaste/phpaste-master

Next, copy the sample Paste configuration file config.sample.php to the config.php file using the following command:

cp config.sample.php config.php

Edit the config.php file and change the following variables as required:

• DB_TYPE to pgsql
• DB_HOST to localhost
• DB_NAME to paste
• DB_USER to the username you want to use for the paste database
• DB_PASS to the password you want to use for the paste database

Step 4: Create the Paste Database

Use the following command to create the Paste database in PostgreSQL:

sudo -u postgres createdb paste

After creating the database, create a new user account with the same username you used in the DB_USER variable in the config.php file. Set a strong password for the user account.

sudo -u postgres createuser pasteuser -P

Step 5: Set Proper Permissions

Set the proper write permissions for the data folder by executing the command:

sudo chown -R apache:apache data

Step 6: Start the PHP-FPM Service

Start the PHP-FPM service by running the following command:

sudo systemctl start php-fpm

Step 7: Start the Nginx Service and Configure VirtualHost

Create a new file called phpaste.conf using your favorite text editor.

sudo vim /etc/nginx/conf.d/phpaste.conf

And add the following configuration lines.

server {
    listen 80;
    server_name paste.example.com; # replace with public domain
    root /path/to/phpaste; # replace with paste path
    index index.php;
    error_log /var/log/nginx/paste_error.log;
    access_log /var/log/nginx/paste_access.log;
    location / {
        try_files $uri $uri/ /index.php$is_args$args;
    }

    location ~ \.php$ {
        try_files $uri =404;
        include /etc/nginx/fastcgi_params;
        fastcgi_pass unix:/run/php-fpm/www.sock;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }
}

Once you have made the above changes, save and exit the file.

Finally, reload the Nginx configuration to apply the changes:

sudo systemctl reload nginx

Step 8: Access Paste

Paste is now installed and can be accessed by visiting the following URL in a web browser:

http://paste.example.com/ # replace with public domain
