I am pleased to announce the immediate availability of version 4 of the Varnish Cache Server on CentOS Linux 7 x86_64, delivered via a Software Collection (SCL) built by the SCLo Special Interest Group (https://wiki.centos.org/SpecialInterestGroup/SCLo). QuickStart ---------- You can get started in three easy steps: $ sudo yum install centos-release-scl $ sudo yum install rh-varnish4 $ scl enable rh-varnish4 bash At this point you should be able to use varnish just as a normal application. An example of commands run might be: $ systemctl start rh-varnish4-varnish $ varnishtop In order to view the individual components included in this collection, including additional subpackages, you can run: $ sudo yum list rh-varnish4* About Software Collections -------------------------- Software Collections give you the power to build, install, and use multiple versions of software on the same system, without affecting system-wide installed packages. Each collection is delivered as a group of RPMs, with the grouping being done using the name of the collection as a prefix of all packages that are part of the software collection. The collection rh-varnish4 delivers version 4 of the Varnish Cache, a high-performance HTTP reverse proxy. The daemon is called rh-varnish4-varnish. For more on the Varnish HTTP, see https://www.varnish-cache.org. The SCLo SIG in CentOS ---------------------- The Software Collections SIG group is an open community group co-ordinating the development of the SCL technology, and helping curate a reference set of collections. In addition to the Varnish Cache collection being released here, we also build and deliver other databases, web servers, and language stacks including multiple versions of PostgreSQL, MariaDB, Apache HTTP Server, NodeJS, Ruby, Python and others. Software Collections SIG release was announced at https://lists.centos.org/pipermail/centos-announce/2015-October/021446.html You can learn more about Software Collections concepts at: http://softwarecollections.org You can find information on the SIG at https://wiki.centos.org/SpecialInterestGroup/SCLo ; this includes howto get involved and help with the effort. We meet every second Wednesday at 16:00 UTC in #centos-devel (ref: https://www.centos.org/community/calendar), for an informal open forum open to anyone who might have comments, concerns or wants to get started with SCL's in CentOS. Enjoy! Honza SCLo SIG member
