+# Setting up Nextcloud with Nginx
+
+## Step 1: Update Repositories and Packages
+
+```bash
+apt update && apt upgrade -y
+```
+
+## Step 2: Install Nginx and MariaDB Server
+
+```bash
+apt install nginx mariadb-server
+```
+
+## Step 3: Install and Enable Dependencies and Certbot
+
+```bash
+apt install imagemagick php-imagick php-common php-mysql php-fpm php-gd php-json php-curl php-zip php-xml php-mbstring php-bz2 php-intl php-bcmath php-gmp php-zip libmagickcore-6.q16-6-extra
+apt install certbot python3-certbot-nginx
+systemctl start php8.1-fpm && systemctl enable php8.1-fpm
+```
+
+## Step 4: Get and Install Nextcloud
+
+```bash
+wget https://download.nextcloud.com/server/releases/nextcloud-28.0.4.zip && mkdir -p /sites/nextcloud && unzip nextcloud-*.zip -d /sites/nextcloud
+```
+
+## Step 5: Configure SQL
+
+```bash
+mysql -u root -p
+```
+
+```sql
+CREATE DATABASE nextcloud_db;
+CREATE USER 'admin2'@'localhost' IDENTIFIED BY '123';
+GRANT ALL PRIVILEGES ON nextcloud_db.* TO 'admin2'@'localhost' IDENTIFIED BY '123';
+FLUSH PRIVILEGES;
+EXIT;
+```
+
+## Step 6: Configure Nginx
+
+```bash
+vim /etc/nginx/sites-enabled/default
+```
+
+**Nginx Configuration**
