Understand WordPress Filesystem Permissions in Bitnami Wordpress

WordPress is a popular content management system (CMS) used by millions of websites worldwide. It is easy to use, and many hosting providers offer one-click installs to get your site up and running quickly. However, to ensure the security and reliability of your WordPress site, it is important to understand the filesystem permissions in Bitnami WordPress.

What are Filesystem Permissions in WordPress?

Filesystem permissions define who can access or modify files and directories on a web server. In WordPress, there are three types of users: the owner, the group, and everyone else. The owner is the user who created the file, the group is a set of users who have access to the file, and everyone else refers to all other users.

There are three types of filesystem permissions: read, write, and execute. Read permission allows a user to view the contents of a file, write permission allows a user to modify a file, and execute permission allows a user to run a file as a program or script.

In Bitnami WordPress, the filesystem permissions are set by default to ensure the security and integrity of your site. However, it is important to understand these permissions to troubleshoot any issues that may arise.

Filesystem Permissions in Bitnami WordPress

Bitnami WordPress installs with a set of default filesystem permissions that are optimized for security and reliability. The WordPress files and directories are owned by the ‘daemon’ user, which is a system user account that has limited permissions to ensure the security of your site.

The following are the default filesystem permissions in Bitnami WordPress:

Directories: 755
Files: 644

Directories with permission 755 allow the owner and group to read, write, and execute, while everyone else can only read and execute. Files with permission 644 allow the owner to read and write, the group to read, and everyone else to read.

These default permissions ensure that your WordPress site is secure and protected from unauthorized access or modification. However, in some cases, you may need to modify the filesystem permissions to troubleshoot issues or install plugins and themes.

Modifying Filesystem Permissions in Bitnami WordPress

To modify the filesystem permissions in Bitnami WordPress, you can use the command-line interface (CLI) or a file manager tool like FileZilla. Here are the steps to modify the permissions using the CLI:

Connect to your server via SSH or open the Bitnami console.
Navigate to the directory or file that you want to modify the permissions for.
Use the ‘chmod’ command to modify the permissions. For example, to give write permission to the group for a directory, you can use the following command:

sudo chmod g+w /path/to/directory

Verify the permissions using the ‘ls -la’ command.

Summary

Bitnami applies the following default permissions to WordPress files and directories:

Files and directories are owned by user bitnami and group daemon.

Directories are configured with permissions 775 by default.
Files are configured with permissions 664 by default.
The wp-config.php file is configured with permissions 640.

If permissions are wrong, use the chmod or chown commands to restore them to their initial state. For example, if TARGET is the WordPress application folder:

sudo chown -R bitnami:daemon TARGET
sudo find TARGET -type d -exec chmod 775 {} \\;
sudo find TARGET -type f -exec chmod 664 {} \\;
sudo chmod 640 TARGET/wp-config.php

Conclusion

Filesystem permissions are an important aspect of securing your WordPress site. Bitnami WordPress installs with default permissions that ensure the security and reliability of your site. However, in some cases, you may need to modify the permissions to troubleshoot issues or install plugins and themes. By understanding the filesystem permissions in Bitnami WordPress, you can ensure the security and integrity of your site.
