When using PHP FPM, applications cannot write to the /tmp directory

Austin Lowery

Symptoms

After enabling PHP FPM, applications such as WordPress are not able to write to the /tmp directory.

PHP FPM enables the following configuration which disables writing to /tmp in the normal manner by default:

PrivateTmp=true

This can be resolved by uncommenting the sys_temp_dir in the php.ini with the following steps:

1. Login to WHM as the root user

2. Navigate to: Home »Software »MultiPHP INI Editor

3. Click on the Editor Mode tab

4. Select the desired PHP version

5. Locate the sys_temp_dir option and remove the ; so that it is uncommented and is set to /tmp

6. Press the blue save button

7. Restart PHP FPM with the following command via Terminal or SSH:

/scripts/restartsrv_apache_php_fpm --restart
