Rsyslogd is configured via the rsyslog.conf file, typically found in /etc. By default, rsyslogd reads the file /etc/rsyslog.conf. This can be changed by a command line option.
Note that configurations can be built interactively via the online rsyslog configuration builder tool.

Configuration file examples can be found in the rsyslog wiki. Also keep the rsyslog config snippets on your mind. These are ready-to-use real building blocks for rsyslog configuration.
There is also one sample file provided together with the documentation set. If you do not like to read, be sure to have at least a quick look at rsyslog-example.conf.
While rsyslogd contains enhancements over standard syslogd, efforts have been made to keep the configuration file as compatible as possible. While, for obvious reasons, enhanced features require a different config file syntax, rsyslogd should be able to work with a standard syslog.conf file. This is especially useful while you are migrating from syslogd to rsyslogd.
