Linux still uses syslogd as the log monitoring process, but sometimes there is a need to modify the Syslog log level to meet the needs of certain tests that generate a large number of log files in a short period of time.
For example, if you do not want an info level log, you can modify the info level to the Err level (only err and above can be output to a file after modification)
1, modify the configuration file/etc/rsyslog.conf or/etc/syslog.conf (CENTOS6 later version, will syslog.conf changed to rsyslog.conf)
Has the following content:
# Don ' t log private authentication messages!
*. Info;mail.none;authpriv.none;cron.none/var/log/messages
Modify. Info to. Err.
2. Restart the syslog process (CENTOS6 later version)
Note: If the old version, you can first PS under the "syslog" related processes, kill the corresponding process, and then restart, it should also be possible (this method has not been tried)
