Use this documentation with care! It describes the heavily outdated version 5, which was actively developed around 2010 and is considered dead by the rsyslog team for many years now.

This documentation reflects the latest update of the previously existing (now removed) v5-stable branch. It describes the 5.10.2 version, which was never released. As such, it contains some content that does not apply to any released version.

To obtain the doc that properly matches your installed v5 version, obtain the doc set from your distro. Each version of rsyslog contained the version that exactly matches it.

As general advise, it is strongly suggested to upgrade to the current version supported by the rsyslog project. The current version can always be found on the right-hand side info box on the rsyslog web site.

Note that there is no rsyslog community support available for this heavily outdated version. If you need to stick with it, please ask your distribution for support.

Installing rsyslog from Package

Installing from package is usually the most convenient way to install rsyslog. Usually, the regular package manager can be used.

Package Availability

Rsyslog is included in all major distributions. So you do not necessarily need to take care of where packages can be found - they are “just there”. Unfortunately, the distros provide often rather old versions. This is especially the case for so-called enterprise distributions.

As long as you do not run into trouble with one of these old versions, using the distribution-provided packages is easy and a good idea. If you need new features, better performance and sometimes even a fix for a bug that the distro did not backport, you can use alternative packages. Please also note that the project team does not support outdated versions. While we probably can help with simple config questions, for anything else we concentracte on current versions.

The rsyslog project offers current packages for a number of “big” distributions. They can be found at http://www.rsyslog.com in the download section.

Note that some distributions (like Fedora) usually keep up with development rather quickly and so we do not provide special packages for them.

If you do not find a suitable package for your distribution, there is no reason to panic. It is quite simple to install rsyslog from the source tarball, so you should consider that.

Package Structure

Almost all distributions package rsyslog in multiple packages. This is also the way Adiscon packages are created. The reason is that rsyslog has so many input and output plugins that enable it to connect to different systems like MySQL, HDFS, ElasticSearch and so on. If everything were provided in a single giantic package, you would need to install all of these dependencies, even though they are mostly not needed.

For that reason, rsyslog comes with multiple packages:

  • core package (usually just called “rsyslog”) - this contains core technology that is required as a base for all other packages. It also contains modules like the file writer or syslog forwareder that is extremely often used and has little dependencies.
  • feature package (usually called “rsyslog-feature”) - there are multiple of these packages. What exactly is available and how it is named depends on the distro. This unfortunately is a bit consistent. Usually, it is a good guess that the package is intuitively named, e.g. “rsyslog-mysql” for the MySQL component and “rsyslog-elasticsearch” for ElasticSearch support. If in doubt, it is suggested to use the distro’s package manager and search for “rsyslog*”.

Contributing

Packaging is a community effort. If you would like to see support for an additional distribution and know how to build packages, please consider contributing to the project and joining the packaging team. Also, rsyslog’s presence on github also contains the sources for the currently maintained packages. They can be found at https://github.com/rsyslog.
