It also pointed out a few example modules and explained the problems they solve. This article puts one of those modules to practical use, covering installation and setup of Review Board 3.0 using modules. + +### Getting started + +To follow along with this article and use modules, you need a system running [Fedora 28 Server Edition][2] along with [sudo administrative privileges][3]. Also, run this command to make sure all the packages on the system are current: +``` +sudo dnf -y update + +``` + +While you can use modules on Fedora 28 non-server editions, be aware of the [caveats described in the comments of the previous article][4]. + +### Examining modules + +First, take a look at what modules are available for Fedora 28. Run the following command: +``` +dnf module list + +``` + +The output lists a collection of modules that shows the associated stream, version, and available installation profiles for each. A [d] next to a particular module stream indicates the default stream used if the named module is installed. + +The output also shows most modules have a profile named default. That’s not a coincidence, since default is the name used for the default profile. + +To see where all those modules are coming from, run: +``` +dnf repolist + +``` + +Along with the usual [fedora and updates package repositories][5], the output shows the fedora-modular and updates-modular repositories. + +The introduction stated you’d be setting up Review Board 3.0. Perhaps a module named reviewboard caught your attention in the earlier output. Next, to get some details about that module, run this command: +``` +dnf module info reviewboard + +``` + +The description confirms it is the Review Board module, but also says it’s the 2.5 stream. However, you want 3.0. Look at the available reviewboard modules: +``` +dnf module list reviewboard + +``` + +The [d] next to the 2.5 stream means it is configured as the default stream for reviewboard. Therefore, be explicit about the stream you want: +``` +dnf module info reviewboard:3.0 + +``` + +Now for even more details about the reviewboard:3.0 module, add the verbose option: +``` +dnf module info reviewboard:3.0 -v + +``` + +### Installing the Review Board 3.0 module + +Now that you’ve tracked down the module you want, install it with this command: +``` +sudo dnf -y module install reviewboard:3.0 + +``` + +The output shows the ReviewBoard package was installed, along with several other dependent packages, including several from the django:1.6 module. The installation also enabled the reviewboard:3.0 module and the dependent django:1.6 module. + +Next, to see enabled modules, use this command: +``` +dnf module list --enabled + +``` + +The output shows [e] for enabled streams, and [i] for installed profiles. In the case of the reviewboard:3.0 module, the default profile was installed. You could have specified a different profile when installing the module. In fact, you still can — and this time you don’t need to specify the 3.0 stream since it was already enabled: +``` +sudo dnf -y module install reviewboard/server + +``` + +However, installation of the reviewboard:3.0/server profile is rather uneventful. The reviewboard:3.0 module’s server profile is the same as the default profile — so there’s nothing more to install. + +### Spin up a Review Board site + +Now that the Review Board 3.0 module and its dependent packages are installed, [create a Review Board site][6] running on the local system. Without further ado or explanation, copy and paste the following commands to do that: +``` +sudo rb-site install --noinput \ + --domain-name=localhost --db-type=sqlite3 \ + --db-name=/var/www/rev.local/data/reviewboard.db \ + --admin-user=rbadmin --admin-password=secret \ + /var/www/rev.local +sudo chown -R apache /var/www/rev.local/htdocs/media/uploaded \ + /var/www/rev.local/data +sudo ln -s /var/www/rev.local/conf/apache-wsgi.conf \ + /etc/httpd/conf.d/reviewboard-localhost.conf +sudo setsebool -P httpd_can_sendmail=1 httpd_can_network_connect=1 \ + httpd_can_network_memcache=1 httpd_unified=1 +sudo systemctl enable --now httpd + +``` + +Now fire up a web browser on the system, point it at , and enjoy the shiny new Review Board site! To login as the Review Board admin, use the userid and password seen in the rb-site command above. + +### Module cleanup + +It’s good practice to clean up after yourself. To do that, remove the Review Board module and the site directory: +``` +sudo dnf -y module remove reviewboard:3.0 +sudo rm -rf /var/www/rev.local + +``` + +### Closing remarks + +Now that you’ve explored how to examine and administer the Review Board module, go experiment with the other modules available in Fedora 28. + +Learn more about using modules in Fedora 28 on the [Fedora Modularity][7] web site. The dnf manual page’s Module Command section also contains useful information. + + +-------------------------------------------------------------------------------- + +via: https://fedoramagazine.org/working-modules-fedora-28/ + +作者：[Merlin Mathesius][a] +选题：[lujun9972](https://github.com/lujun9972) +译者：[译者ID](https://github.com/译者ID) +校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 + +[a]:https://fedoramagazine.org/author/merlinm/ +[1]:https://fedoramagazine.org/modularity-fedora-28-server-edition/ +[2]:https://getfedora.org/server/ +[3]:https://fedoramagazine.org/howto-use-sudo/ +[4]:https://fedoramagazine.org/modularity-fedora-28-server-edition/#comment-476696 +[5]:https://fedoraproject.org/wiki/Repositories +[6]:https://www.reviewboard.org/docs/manual/dev/admin/installation/creating-sites/ +[7]:https://docs.pagure.org/modularity/
