Fixing the “bin/magento: permission denied” Error in Magento 2

The frustrating “bin/magento: permission denied” error message can halt your progress in managing your Magento 2 store. This tutorial guides you through several methods to fix this issue and get back to running Magento CLI commands smoothly.

Cause:

This error occurs when the bin/magento file lacks the necessary permissions to be executed. Magento requires specific owner and group ownership as well as execute (x) permissions for this file to function properly.

Method 1: Adjusting File Permissions

Navigate to Magento root directory: Use your terminal or SSH client to navigate to the root directory of your Magento 2 installation.
Check current permissions: Run the ls -l command to see the currentfile permissions for bin/magento. Look for the third set of three digits representing permissions. Ideally, it should be 755, where 7 signifies full permissions for the owner, 5 signifies read and execute permissions for the group, and 5 signifies read and execute permissions for others.
Set correct permissions: Use the chmod command to grant execute permissions.If the current permissions are not 755, run the following command:

sudo chmod 755 bin/magento

Verify and try again: Run ls -l again to confirm the change and then attempt your Magento CLI command (bin/magento).

Method 2: Using the php Prefix

This method avoids changing file permissions directly by prepending the php command before your Magento CLI command.

Run the command with php prefix:

php bin/magento

This instructs the system to execute the bin/magento file directly using the PHP interpreter, bypassing the permission check.

Method 3: Checking Ownership

In rare cases, the issue might be related to file ownership.

Check the owner and group of bin/magento: Use the ls -l command again. The first username and group name displayed represent the owner and group, respectively.
Compare with recommended settings: Magento documentation recommends the www-data user and group for file ownership. If ownership differs, consult your hosting provider or system administrator for guidance on changing ownership without compromising security.

Additional Tips:

Always back up files before making changes.
Consider using a dedicated user account for running Magento commands with appropriate permissions.
Consult the Magento documentation for specific permission recommendations based on your server configuration.
If the issue persists after trying these methods, search online forums or contact Magento support for further assistance.

By following these steps, you should be able to troubleshoot the “bin/magento: permission denied” error and resume managing your Magento store through the CLI. Remember to adjust the commands and procedures based on your specific server environment and Magento version.
