Symptoms

• Client IP address is not shown in the global Apache logfile when nginx is used as a proxy web-server.

• The Apache module "mod_remoteip" is enabled:

  # apachectl -M | grep remoteip
  remoteip_module (shared)

Cause

Combined logs format is not configured.

Resolution

1. Connect to the Plesk server via SSH.

2. Open the file /etc/httpd/conf/httpd.conf in a text editor and navigate to the following line:

   CONFIG_TEXT: LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined

3. Add the "%a" parameter to display the client IP address:

   CONFIG_TEXT: LogFormat "%a %h  %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined

4. Save the changes and close the file.

5. Reload Apache configuration:

   # service httpd reload
