This article mainly introduces the Ubuntu Syslog configuration / var/log/messages example analysis, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

1. Problem description

I need to check the log file of the system today, but I can't find the file / var/log/messages. Search for information on the Internet, it is said to configure / etc/syslog.conf. Syslog adopts a configurable and unified system registration program to accept log requests from all parts of the system at any time, and then write the log information into the corresponding file, mail it to a specific user or send it directly to the console according to the preset settings in / etc/syslog.conf.

Okay, here's the problem again. There is still no / etc/syslog.conf in the system, after a search, the final conclusion is: the corresponding under Ubuntu should be / etc/rsyslog.conf and rsyslogd.

two。 Solution

For more information on the functions of syslog.conf files and files under syslog.d, please refer to the following article:

Https://www.jb51.net/article/164470.htm

By looking at the rsyslog.conf file, you can see that all the configuration files are in the / etc/rsyslog.d/ folder.

# / etc/rsyslog.conf Configuration file for rsyslog. # # For more information see # / usr/share/doc/rsyslog-doc/html/rsyslog_conf.html # # Default logging rules can be found in / etc/rsyslog.d/50-default.conf … ... # # Include all config files in / etc/rsyslog.d/ # $IncludeConfig / etc/rsyslog.d/*.conf

Open the / etc/rsyslog.d/50-default.conf file with vim and add a line as follows:

* .info;mail.none;authpriv.none;cron.none / var/log/messages

Restart the system, then check the system log and find that it is already okay! ^ _ ^
