Ubuntu VPS主机

Step 1: Access Your Ubuntu VPS

Once deployed, connect to your server via SSH:

ssh root@your-server-ip

Step 2: Update System Packages

Always start by updating your package lists and installed packages:

apt update && apt upgrade -y

Step 3: Configure Firewall (UFW)

Ubuntu includes UFW (Uncomplicated Firewall) for easy firewall management:

# Enable firewall
ufw enable

# Allow SSH (important!)
ufw allow 22/tcp

# Allow HTTP/HTTPS
ufw allow 80/tcp
ufw allow 443/tcp

# Check status
ufw status

Step 4: Install Essential Tools

Install commonly needed packages:

apt install -y curl wget git vim build-essential

Step 5: Set Up Your Application

Install your web stack. For example, LEMP stack (Nginx, MySQL, PHP):

# Install Nginx
apt install -y nginx

# Install MySQL
apt install -y mysql-server

# Install PHP
apt install -y php-fpm php-mysql

# Start services
systemctl start nginx
systemctl enable nginx
