Ensure a Syslog Facility Is Configured for Error Logging

낮음레벨 2자동apache

설명

The ErrorLog directive should be configured to send logs to a syslog facility so that the logs can be processed and monitored along with the system logs. The global ErrorLog must use syslog (e.g. syslog:local1) and no virtual host may override it with a file. Reads the main configuration (APACHE_CONF overrides; default /etc/apache2/apache2.conf, /etc/httpd/conf/httpd.conf or /usr/local/apache2/conf/httpd.conf) and every Include/IncludeOptional file. CIS marks this recommendation Manual; the automated check implements its audit procedure.

Set ErrorLog "syslog:local1" in the main configuration and remove file-based ErrorLog directives from virtual hosts (or point them to syslog). Then run apachectl configtest and reload Apache.
