RHCSA Rapid Track

Instructions

1. Log in to the servera machine as the student user and switch to the root user.

   [student@workstation ~]$ ssh student@servera
   ...output omitted...
   [student@servera ~]$ sudo -i
   [sudo] password for student: student
   [root@servera ~]#

2. Configure the rsyslog service on the servera machine to log all messages with the debug or higher priority, for any service to the new /var/log/messages-debug log file by changing the /etc/rsyslog.d/debug.conf configuration file.

   1. Create the /etc/rsyslog.d/debug.conf file with the necessary entries to redirect all log messages with the debug or higher priority to the /var/log/messages-debug log file.

      *.debug /var/log/messages-debug

      This configuration line logs syslog messages with any facility and with the debug or higher priority level:

      • The wildcard (*) in the facility field of the configuration line indicates any facility of log messages.

      • The rsyslog service writes the matching messages to the /var/log/messages-debug log file.

   2. Restart the rsyslog service.

      [root@servera ~]# systemctl restart rsyslog

3. Verify that all the log messages with the debug priority appear in the /var/log/messages-debug log file.

   1. Generate a log message with the user type and the debug priority.

      [root@servera ~]# logger -p user.debug "Debug Message Test"

   2. View the last ten log messages from the /var/log/messages-debug log file, and verify that you see the Debug Message Test message among the other log messages.

      [root@servera ~]# tail /var/log/messages-debug
