Create a web project with Tailwind CSS

Şükrü Çakmak tarafından 18 Aralık 2022 tarihinde gönderildi

Project folder and Node.js activation

mkdir tailwind-demo
cd tailwind-demo
npm init

Install Tailwind CSS

npm install -D tailwindcss
npx tailwindcss init

You will have dev dependency for tailwind and tailwind.config.css

Configure path

Change content element like below to dedicate the directory.

content: ["./src/**/*.{html,js}"],

Add Tailwind directives

Create src folder and input.css file. You will have src/input.css, then add below lines.

@tailwind base;
@tailwind components;
@tailwind utilities;

Tailwind CSS Watch Tool into package.json

Add this watch script into your package.json scripts section. We will start our project with this command later.

"watch": "npx tailwindcss -i ./src/input.css -o ./dist/output.css --watch"

Create a HTML page for testing purpose

Under src folder create an index.html file, then add below lines.

<!doctype html>
<html>
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <link href="/dist/output.css" rel="stylesheet">
</head>
<body>
  <h1 class="text-3xl font-bold underline">
    Hello world!
  </h1>
</body>
</html>

Start your project

npm run watch

Open index.html file in your browser by using LiveServer or another testing tool. You will see the page with Tailwind support. Enjoy.

Şükrü Çakmak tarafından 20 Haziran 2021 tarihinde gönderildi

It is a cheat sheet for SFTP configuration on CentOS. Long version is on DigitalOcean.

Create a User

sudo adduser xfiles
sudo passwd xfiles

Create a Directory for File Transfers

sudo mkdir -p /var/sftp/uploads
sudo chown root:root /var/sftp
sudo chmod 755 /var/sftp
sudo chown xfiles:xfiles /var/sftp/uploads

Configure SSH Deamon

sudo vi /etc/ssh/sshd_config

Match User xfiles
ForceCommand internal-sftp
PasswordAuthentication yes
ChrootDirectory /var/sftp
PermitTunnel no
AllowAgentForwarding no
AllowTcpForwarding no
X11Forwarding no

Restart SSD Deamon

sudo systemctl restart sshd

Test in the Server

sftp xfiles@localhost

Well Done!

VNC ile RHEL Uzak Masaüstü

Şükrü Çakmak tarafından 8 Kasım 2019 tarihinde gönderildi
  1. Önce bir desktop uygulaması yüklememiz lazım.
    yum groupinstall "GNOME Desktop"
  2. TigerVNC sunucusunu fontlarıyla birlikte yüklemeliyiz.
    yum install tigervnc-server xorg-x11-fonts-Type1
  3. 5903 portundan yayın yapabilmesi için bir service oluşturalım.
    cp /lib/systemd/system/[email protected] /etc/systemd/system/vncserver@:3.service
  4. Kullanıcı bilgisini tüm <USER> alanlarını değiştirerek güncelleyelim.
    vi /etc/systemd/system/vncserver@:3.service
  5. İlgili kullanıcıya geçiş yapıp vncserver için kullanıcı ve şifre oluşturalım.
    vncserver
  6. Aşağıdaki komutlarla da deamonu enable edip başlatalım
    systemctl daemon-reload
    systemctl start vncserver@:3.service
    systemctl enable vncserver@:3.service

Artık VNC viewer ile bağlanabiliriz 🙂
