# 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**

```conf

    server unix:/var/run/php/php8.1-fpm.sock;

## Step 7: Nginx Check

```bash
nginx -t # Check if configuration has errors
nginx -s reload
```
