Error: Failed to create temporary file

Issue
======

The apache error log shows

[Wed Oct 28 23:49:30 2015] [error] [client xx.xx.xxx.xxx] ModSecurity: Input filter: Failed to create temporary file: /root/tmp/20151028-234930-VjGXSkAWQiQAA@W7VAsAAAAD-request_body-nKiZdT [hostname "www.xxxx.com"] [uri "/wp-admin/admin.php"] [unique_id "VjGXSkAWQiQAA@W7VAsAAAAD"]

The issue is because the modsecurity has no access on /root/tmp directory.

So while accessing /root/tmp it will show the error “Failed to create temporary file”

Fix
===

The issue can be fixed by adding the following lines on the configuration file of modsecurity.

# vi /usr/local/apache/conf/modsec2.conf

Add these below lines in /usr/local/apache/conf/modsec2.conf

SecUploadDir /tmp
SecTmpDir /tmp
SecDataDir /tmp
SecRequestBodyAccess On

Now you need to restart apache to make the changes effective

 service httpd restart

This will fix the issue normally
