Creating a Review Board Site¶
Once Review Board is installed, a site must be created. Each site maps to a domain, subdomain, or directory installation.
To create a site, you will use the
rb-site install command.
You will need to decide on a place to install the site. In the examples
here, we will use
/var/www/reviews.example.com. The directory
should not exist yet. rb-site will create it.
Creating the Database¶
Before you create the Review Board site, you’ll need to create a database. The particular steps for this depend on the database server software that you intend to use.
SQLite should only be used for test installations.
While useful and portable, SQLite does not handle large loads with many concurrent users very well. We strongly recommend using MySQL or PostgreSQL for a real deployment.
We don’t officially support converting a database from SQLite to other databases, so it’s important that you choose something that will work for you long-term.
In MySQL, before creating your database, make sure that your server is
configured to use the UTF-8 encoding for text. In the file
the following settings:
[client] default-character-set=utf8 [mysqld] character-set-server=utf8
After making these changes, restart your MySQL server.
Next, start up the mysql command prompt as your root user, and create a new
database and user (replacing
myspassword with your desired
username and password, respectively):
$ mysql -u root -p mysql> CREATE DATABASE reviewboard CHARACTER SET utf8; mysql> CREATE USER 'myuser'@'localhost' IDENTIFIED BY 'mypassword'; mysql> GRANT ALL PRIVILEGES ON reviewboard.* to 'myuser'@'localhost';
To create a Postgres database, you’ll need to run several commands as the
postgres user. Start by running the following command (the particular
username may depend on your choice of operating system):
$ sudo su - postgres
Next, as the postgres user, create a database and a user to access it:
$ createdb reviewboard $ createuser -P --interactive
The second of these commands will ask you several questions. For the last three questions (relating to permissions), reply ‘n’.
Finally, grant permissions for this user to your new database:
$ psql => GRANT ALL PRIVILEGES ON DATABASE reviewboard to myuser
Begin installation by running the following command:
$ rb-site install /var/www/reviews.example.com
You will now be asked a series of questions about your site setup. It is expected that you will know the answers to these questions. If not, you’ll have to decide what software you want to use for your services and refer to their documentation on how to set them up and configure them.
We recommend mod_wsgi and memcached
If you’re using Apache, we highly recommend using mod_wsgi. fastcgi has been known to have several issues (including memory leaks and problems when using the LDAP authentication backend), and mod_python is no longer developed or shipped with Apache.
We also strongly recommend installing and using memcached. This will greatly improve performance of your Review Board installation. If possible, put this on a server with a lot of RAM.
Apache should use the Prefork MPM
The Worker MPM uses multiple threads, which can cause numerous problems with Review Board’s dashboard and extensions implementations. In order for Review Board to work correctly, it should use the single-threaded Prefork MPM.
Once you have answered all the questions and completed the installation, you’ll need to change some directory permissions and install your web server configuration files.
Review Board expects to be able to write to the following directories and their subdirectories:
Since Review Board is run by your web server, these directories and all subdirectories and files must be writable by the user your web server runs as.
This user varies by operating system, distribution and web server, so you may need to look it up. If your web server is currently running, you can look at what user it’s running as.
Once you’ve figured this out, go ahead and change the permissions on the
directories. For example, in Linux/UNIX/MacOS X with a
$ chown -R www-data /var/www/reviews.example.com/data $ chown -R www-data /var/www/reviews.example.com/htdocs/media/uploaded $ chown -R www-data /var/www/reviews.example.com/htdocs/media/ext $ chown -R www-data /var/www/reviews.example.com/htdocs/static/ext
If you’re using SQLite as your database, you will also need to change the
ownership of the site’s
db directory to match the web server’s
user. Otherwise, you may receive an Internal Server Error when accessing
Web Server Configuration¶
rb-site provides sample web server configuration files in the newly
conf/ directory under your new site directory. In many installs,
these files will work out of the box, but they may require modification
depending on the rest of your web server configuration.
The configuration file will be based on the web server type and Python loader
you’ve specified. For example, if you used Apache and wsgi, you would
Installing these files is also dependent on the web server and operating system/distribution.
There are two possible Apache configuration files that will be generated,
depending on whether you selected
during rb-site install.
If you selected
mod_wsgi, your configuration file will be
If you selected
mod_python, your configuration file will be
If you selected
fastcgi, your configuration file will be
Depending on your operating system or Linux distribution, the configuration file can be installed in a couple different ways.
If you have a
sites-available directory in your Apache
configuration directory (for example,
then you should rename your configuration file to match your site
reviews.example.com.conf) and put it in that directory. Then
create a symbolic link from that file to the
directory. This is the most common setup on Debian or Ubuntu-based
distributions. So for example:
$ cd /etc/apache2/sites-available $ cp /var/www/reviews.example.com/conf/apache-wsgi.conf reviews.example.com.conf $ cd ../sites-enabled $ ln -s ../sites-available/reviews.example.com.conf .
If you do not have a
directory, you’ll need to embed the configuration file in your global
Apache configuration file (usually
On Fedora, you can do:
$ ln -s /path/to/apache-wsgi.conf /etc/httpd/conf.d/reviewboard-sitename.conf
Of course, the configuration file can be placed anywhere so long as it’s at some point included by your main Apache configuration file.
Once you’ve installed the configuration file, restart Apache and then try going to your site.
Some Apache installations (such as the default installs on Debian
and Ubuntu) by default define a global virtual host that shares
/var/www as the document root. This may lead to problems
with your install. If you access your site and see nothing but
a directory listing, then you’re affected by this problem.
The solution is to remove the “default” site from your
/etc/apache2/sites-enabled directory. This may be
called something like
On Fedora and Red Hat-derived systems, the following commands should be run (as root) to avoid SELinux denials:
$ setsebool -P httpd_can_sendmail 1 $ setsebool -P httpd_can_network_connect 1 $ setsebool -P httpd_can_network_memcache 1 $ setsebool -P httpd_can_network_connect_db 1 $ setsebool -P httpd_unified 1
These lighten the SELinux enforcement to allow the web server process to be able to send email, access the caching server, connect to a remote database server and support uploading diffs, respectively.
Additionally, if you are using Review Board with a remote LDAP server, you should also run (as root):
$ setsebool -P httpd_can_connect_ldap 1
The generated configuration file for lighttpd will be saved as
You should either add the contents of this file to your
/etc/lighttpd/lighttpd.conf, or include it directly from
lighttpd.conf using the
include directive. See the
lighttpd documentation for more information.
