When running websites or applications that rely heavily on databases, the “Too Many Connections” error in MySQL can be a frustrating issue. This error means that the maximum number of allowed connections to your MySQL database has been reached — preventing new users or processes from connecting.

If you’re hosting your website on Sternhost VPS, this guide will show you how to quickly identify the problem and apply effective fixes.

Understanding the Error

By default, MySQL allows 151 simultaneous connections. When all connections are used up — due to high traffic, poorly optimized queries, or unclosed connections — MySQL blocks new ones and throws the error:

This usually happens on busy or poorly optimized websites.

Step 1: Check Current Connection Limit

You can start by logging into your MySQL terminal or using phpMyAdmin, then run:

This command displays your current connection limit.

To check how many connections are currently in use:

Step 2: Temporarily Increase the Connection Limit

If your website is under heavy load, you can increase the limit temporarily using:

⚠️ This change is temporary and will reset after MySQL restarts.

Step 3: Make the Change Permanent

To apply the new limit permanently, edit your MySQL configuration file:

For CentOS / Ubuntu users:

or

Then, under the [mysqld] section, add or update:

Finally, restart MySQL:

Step 4: Optimize Database Performance

Simply increasing connections isn’t always the best fix. You should also:

• Optimize queries: Identify slow queries with:

  SHOW PROCESSLIST;


• Use persistent connections wisely: Avoid leaving them open unnecessarily.

• Upgrade your plan: If you’re consistently hitting the limit, consider upgrading your Sternhost VPS plan for more resources.

• Enable caching: Implement caching (like Redis or Memcached) to reduce MySQL load.

Step 5: Monitor Database Usage

Sternhost provides powerful monitoring tools for VPS users. Regularly check your MySQL resource usage, CPU load, and memory allocation to prevent future issues.

You can also automate alerts or use plugins like MySQLTuner to review performance recommendations.

The “Too Many Connections” error in MySQL is a sign of either high usage or inefficiency. By optimizing your queries, increasing the connection limit, and using Sternhost’s high-performance VPS hosting, you can maintain smooth and reliable database operations.

Directory browsing is a web server feature that allows visitors to view the list of files stored in a directory when no index file (like index.html or index.php) is present. While it is generally disabled for security reasons, there are situations where enabling it can be useful—for example, when you want to provide direct access to software downloads, image galleries, or documentation files.

In this guide, we’ll show you how to enable directory browsing for specific folders in your hosting account using .htaccess.

Why Enable Directory Browsing?

Enabling directory browsing can help in scenarios such as:

• File Sharing: Easily share multiple files without creating individual links.

• Open Repositories: Make software or documentation accessible in a folder.

• Media Galleries: Allow users to view/download images, videos, or PDFs directly.

⚠️ Note: Directory browsing can expose sensitive files if not carefully controlled. Always enable it only in specific, non-sensitive directories.

Enabling Directory Browsing with .htaccess

Most hosting providers (including Sternhost) allow you to control directory browsing through the .htaccess file. Here’s how:

Step 1: Access Your File Manager or FTP

1. Log in to your cPanel or VPS.

2. Open File Manager or connect via FTP.

3. Navigate to the specific folder where you want directory browsing enabled.

Step 2: Create or Edit .htaccess File

1. Inside the folder, check if a .htaccess file exists.

   • If it doesn’t, create a new file named .htaccess.

2. Add the following line to the .htaccess file:

This enables directory listing for that folder.

Step 3: Customize the Directory Listing (Optional)

You can also adjust how the listing looks with these directives:

• FancyIndexing – Makes the directory listing look cleaner.

• SuppressDescription – Removes extra file details like descriptions.

• SuppressHTMLPreamble – Useful if embedding in custom HTML pages.

Step 4: Save and Test

• Save the .htaccess file.

• Open your browser and visit the folder’s URL (e.g., https://yourdomain.com/foldername/).

• You should now see a list of files available for access.

How to Disable Directory Browsing Again

If you later decide to remove access, simply update your .htaccess file with:

This will disable directory browsing immediately.

Best Practices and Security Tips

• Never enable browsing for your root or sensitive directories (like /public_html, /wp-admin/, /config/).

• Create a dedicated folder for files you want to share.

• Use passwords or authentication if files should only be accessible to specific users.

Enabling directory browsing for specific folders can be a quick way to share files or host an open resource directory on your website. With a simple .htaccess update, you can control exactly where and how this feature is available.

If you’re using Sternhost VPS or cPanel hosting, the process is straightforward and can be implemented in just a few minutes.
