This is How to Change the wp-content Temp Directory to /tmp in WordPress
As a WordPress developer or website owner, you may have encountered the need to change the default wp-content temp directory. This directory is used by WordPress to store various temporary files, such as those generated during image processing or plugin installations. By default, WordPress stores these files in the wp-content/uploads/temp directory, but you may want to change this location for a variety of reasons.
Why Change the wp-content Temp Directory?
There are several reasons why you might want to change the default wp-content temp directory in WordPress:
-
Performance Optimization: Storing temporary files in a separate location, such as the system's /tmp directory, can help improve the overall performance of your WordPress site. The /tmp directory is often located on a separate partition or drive, which can help reduce disk I/O on your main WordPress installation.
-
Security Considerations: The default wp-content/uploads/temp directory is part of the web-accessible directory structure of your WordPress site. This means that any files stored in this directory can potentially be accessed by unauthorized users. By moving the temp directory to a non-web-accessible location, such as /tmp, you can improve the security of your WordPress installation.
-
Disk Space Management: If your WordPress site generates a lot of temporary files, the default wp-content/uploads/temp directory can quickly consume a significant amount of disk space. By relocating the temp directory to /tmp, you can free up space in your wp-content directory and better manage your server's storage resources.
-
Compliance and Regulatory Requirements: Depending on your industry or the nature of your WordPress site, you may have specific compliance or regulatory requirements that necessitate the use of a dedicated temporary directory, such as /tmp.
Step-by-Step Guide: Changing the wp-content Temp Directory to /tmp
Now that you understand the benefits of changing the wp-content temp directory, let's go through the steps to make this change in your WordPress installation.
1. Verify the /tmp Directory Permissions
Before you start, make sure that the /tmp directory on your server has the appropriate permissions to allow WordPress to write temporary files. The /tmp directory should be writable by the user or group that your WordPress installation is running under.
You can check the permissions of the /tmp directory using the following command in your terminal:
ls -l /tmp
The output should show that the /tmp directory has the appropriate permissions, typically drwxrwxrwt
or similar.
2. Create a New Temp Directory in /tmp
Next, you'll need to create a new directory within the /tmp directory that will be used as the new wp-content temp directory. You can do this using the following command:
sudo mkdir /tmp/wordpress-temp
Make sure to replace wordpress-temp
with a name that suits your needs.
3. Set the Permissions for the New Temp Directory
After creating the new temp directory, you'll need to set the appropriate permissions to allow WordPress to write files to it. You can do this using the following command:
sudo chmod 755 /tmp/wordpress-temp
This will set the permissions to allow the directory owner (typically the web server user) to read, write, and execute files, while allowing everyone else to read and execute files.

4. Update the WordPress Configuration
Now that you have the new temp directory set up, you need to update your WordPress configuration to use this new location. You can do this by adding the following line to your wp-config.php
file:
define('WP_TEMP_DIR', '/tmp/wordpress-temp');
This line tells WordPress to use the /tmp/wordpress-temp
directory as the new temp directory for your WordPress installation.
5. Clear the Existing Temp Directory
After making the configuration change, you should clear the existing wp-content/uploads/temp directory to ensure that any temporary files are moved to the new location. You can do this by deleting the contents of the wp-content/uploads/temp
directory using an FTP client or your server's file management tool.
6. Test the New Temp Directory
To ensure that the new temp directory is working as expected, try performing an action in your WordPress site that would normally generate temporary files, such as uploading an image or installing a plugin. Verify that the new files are being created in the /tmp/wordpress-temp
directory, and that your WordPress site is functioning correctly.
Verifying the Temp Directory Change
You can verify that the temp directory change was successful by checking the following:
-
WordPress Debug Log: Enable the WordPress debug log by adding the following lines to your wp-config.php
file:
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
Then, check the WordPress debug log (usually located at wp-content/debug.log
) for any errors or warnings related to the temp directory change.
-
Server Logs: Check your server's error logs for any issues related to the temp directory change. The location of these logs will depend on your server configuration, but they are typically located in the /var/log/
directory.
-
WordPress Site Functionality: Perform various actions on your WordPress site, such as uploading images, installing plugins, and so on, to ensure that the site is functioning correctly with the new temp directory.
