I am pleased to announce the immediate availability of Phusion Passenger in version 4.0 on CentOS Linux 6 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-passenger40 rh-passenger40-ruby22 nginx16 $ scl enable rh-passenger40 rh-ruby22 bash At this point you should be able to use passenger just as a normal application. An examples of commands run might be: $ passenger start $ passenger status In order to view the individual components included in this collection, including other packages that allow you to use passenger with Ruby 2.0 or 1.9.3, instead of 2.2 as in example above, you can run: $ sudo yum list rh-passenger40\* The rh-passenger40 collection relies either on the rh-ruby22, ruby200 or ruby193 collection and the nginx16 collection, so you need to install one of the following packages: rh-passenger40-ruby193, rh-passenger40-ruby200, or rh-passenger40-ruby22. 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-passenger40 delivers Phusion Passenger, a web and application server designed to be fast, robust and lightweight. The rh-passenger40 Software Collection can also be used with Apache HTTP Server from the httpd24 Software Collection. To do so, install the rh-passenger40-mod_passenger package. For more on the Phusion Passenger, see https://www.phusionpassenger.com. 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 Phusion Passenger collections being released here, we also build and deliver 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 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
