will be automatically installed as packages dependencies.

\section{Installation Baculum API from rpm binary packages}

{\bf Note}
Before start using Baculum API and Baculum Web version 9.0.0 please backup
your Bacula configuration in safe place. It is specially important because
on first save config action the Bacula configuration is joined into one file
per Bacula component.\\

For rpm binary there are the following packages:

\begin{itemize}
\item baculum-api - main Baculum API package with application files
\item baculum-api-httpd - Apache web server configuration files for Baculum API
\item baculum-api-lighttpd - Lighttpd web server configuration files for Baculum API
\item baculum-common - Common files for Baculum API and Baculum Web
\item baculum-web - main Baculum Web package with application files
\item baculum-web-httpd - Apache web server configuration files for Baculum Web
\item baculum-web-lighttpd - Lighttpd web server configuration files for Baculum Web
\end{itemize}

\subsection{Add the Baculum rpm repository}

To add the Baculum repository, first you must import the Baculum public key:

\begin{verbatim}
rpm --import http://bacula.org/downloads/baculum/baculum.pub
\end{verbatim}

Once the key is imported, the next step is to add the repository
definition.  First you must create the following file:

\begin{verbatim}
/etc/yum.repos.d/baculum.repo
\end{verbatim}

The for CentOS 7, put the following in the file just created:

\begin{verbatim}
[baculumrepo]
name=Baculum CentOS repository
baseurl=http://bacula.org/downloads/baculum/stable/centos
gpgcheck=1
enabled=1
\end{verbatim}

For Fedora 25 the {\bf bacula.repo} file should have the following contents:

\begin{verbatim}
[baculumrepo]
name=Baculum Fedora repository
baseurl=http://bacula.org/downloads/baculum/stable/fedora
gpgcheck=1
enabled=1
\end{verbatim}

\subsection{Installation for the Apache}

Install the Baculum API for the Apache Web server as follows:

\begin{verbatim}
yum install baculum-common baculum-api baculum-api-httpd
\end{verbatim}

Restart your Apache Web server:

\begin{verbatim}
service httpd restart
\end{verbatim}


\subsection{Installation for Lighttpd}

Installation on system with access via Lighttpd is as follows

\begin{verbatim}
yum install baculum-common baculum-api baculum-api-lighttpd
\end{verbatim}

Please note that in case CentOS distribution the Lighttpd web server is
available in the distribution packages after enabling the EPEL repository.

Start Baculum as application using the Lighttpd Web server:

\begin{verbatim}
service baculum-api-lighttpd start
\end{verbatim}

\subsection{Access to bconsole via sudo for Apache and Lighttpd}

Baculum API requires access to Bconsole and to Bacula JSON programs.
To configure Bconsole sudo access and the Bacula JSON programs access 
there can use following entries in newly created Baculum sudoers.d file
(usually in path /etc/sudoers.d/baculum):\\

In case default Apache user, the file contents must be:

\begin{verbatim}
Defaults:apache !requiretty
apache  ALL=NOPASSWD:  /usr/sbin/bconsole
apache  ALL=NOPASSWD:  /usr/sbin/bdirjson
apache  ALL=NOPASSWD:  /usr/sbin/bsdjson
apache  ALL=NOPASSWD:  /usr/sbin/bfdjson
apache  ALL=NOPASSWD:  /usr/sbin/bbconsjson
\end{verbatim}

In case default Lighttpd user the file contents must be:

\begin{verbatim}
Defaults:lighttpd !requiretty
lighttpd  ALL=NOPASSWD:  /usr/sbin/bconsole
lighttpd  ALL=NOPASSWD:  /usr/sbin/bdirjson
lighttpd  ALL=NOPASSWD:  /usr/sbin/bsdjson
lighttpd  ALL=NOPASSWD:  /usr/sbin/bfdjson
lighttpd  ALL=NOPASSWD:  /usr/sbin/bbconsjson
\end{verbatim}

\section{Installation Baculum API from deb binary packages}

{\bf Note}
Before start using Baculum API and Baculum Web version 9.0.0 please backup
your Bacula configuration in safe place. It is specially important because
on first save config action the Bacula configuration is joined into one file
per Bacula component.\\

For deb binary there are the following packages:

\begin{itemize}
\item baculum-api - main Baculum API package with application files
\item baculum-api-apache2 - Apache web server configuration files for Baculum API
\item baculum-api-lighttpd - Lighttpd web server configuration files for Baculum API
\item baculum-common - Common files for Baculum API and Baculum Web
\item baculum-web - main Baculum Web package with application files
\item baculum-web-apache2 - Apache web server configuration files for Baculum Web
\item baculum-web-lighttpd - Lighttpd web server configuration files for Baculum Web
\end{itemize}

\subsection{Add the Baculum deb repository}

To add the Baculum repository, first import the Baculum public key:

\begin{verbatim}
wget -qO - http://bacula.org/downloads/baculum/baculum.pub | apt-key add -
\end{verbatim}

Once the key is imported, the next step is to create
a new baculum file:

\begin{verbatim}
/etc/apt/sources.list.d/baculum.list
\end{verbatim}

For Debian 8 Jessie the contents should be:

\begin{verbatim}
deb http://bacula.org/downloads/baculum/stable/debian jessie main
deb-src http://bacula.org/downloads/baculum/stable/debian jessie main
\end{verbatim}

For Debian 9 Stretch the contents should be:

\begin{verbatim}
deb http://bacula.org/downloads/baculum/stable/debian stretch main
deb-src http://bacula.org/downloads/baculum/stable/debian stretch main
\end{verbatim}

For Ubuntu 16.04 Xenial the contents should be:
\begin{verbatim}
deb [ arch=amd64 ] http://bacula.org/downloads/baculum/stable/ubuntu xenial main
deb-src http://bacula.org/downloads/baculum/stable/ubuntu xenial main
\end{verbatim}


After adding repository definition, please refresh repository indexes:
\begin{verbatim}
apt-get update
\end{verbatim}

\subsection{Installation for Apache}

To install Baculum API access via Apache Web server by using apt
packages manager use the command:

\begin{verbatim}
apt-get install baculum-common baculum-api baculum-api-apache2
\end{verbatim}

Next you must enable mod\_rewrite module for Apache, with the
following command:

\begin{verbatim}
a2enmod rewrite
\end{verbatim}

and include Baculum VirtualHost definition in the Apache configuration
with:

\begin{verbatim}
a2ensite baculum-api
\end{verbatim}

The restart your Apache server with:

\begin{verbatim}
service apache2 restart
\end{verbatim}

\subsection{Installation for Lighttpd}

Example installation with access via Lighttpd web server looks following:

\begin{verbatim}
apt-get install baculum-common baculum-api baculum-api-lighttpd
\end{verbatim}

Start Baculum API as application available through Lighttpd web server:

\begin{verbatim}
service baculum-api-lighttpd start
\end{verbatim}

\subsection{Access to bconsole via sudo for Apache and Lighttpd}

Baculum API requires access to Bconsole and to the Bacula JSON programs.
To configure Bconsole sudo access we strongly recommend that you create
a Baculum sudoers.d file, which should be in /etc/sudoers.d/baculum:

{\bf Note}, please define sudo for the Bacula JSON programs only when
you are going use Bacula configuration module in the Baculum.

Both for Apache and Lighttpd user the file contents can be:

\begin{verbatim}
Defaults:www-data !requiretty
www-data  ALL=NOPASSWD:  /usr/sbin/bconsole
www-data  ALL=NOPASSWD:  /usr/sbin/bdirjson
www-data  ALL=NOPASSWD:  /usr/sbin/bsdjson
www-data  ALL=NOPASSWD:  /usr/sbin/bfdjson
www-data  ALL=NOPASSWD:  /usr/sbin/bbconsjson
\end{verbatim}

\section{Debugging your First Baculum API Login}
At each step of the initial login to Baculum, the
screen will have a test button that will allow you
to check to see if your parameters were correctly
entered.  If not, you will see error message on the
wizard page. You can also get additional detail by
examining the Apache error log, that is usually 
found at:

\begin{verbatim}
/var/log/httpd/baculum-api-error.log
\end{verbatim}

If you use Lighttpd thento get additional detail you can check:

\begin{verbatim}
/var/log/lighttpd/baculum-api-error.log
\end{verbatim}

In addition, special debug output is placed by Baculum in
the file:

\begin{verbatim}
/usr/share/baculum/htdocs/protected/API/Logs/baculum-api.log
\end{verbatim}

The debug you can enable in file:
\begin{verbatim}
/usr/share/baculum/htdocs/protected/API/Config/api.conf
\end{verbatim}

by switching in [api] section option debug to "1".

With the information in those two files, you can usually quickly
find and correct most problems.

\section{Installation from the Source Tar File}

You may also install Baculum from the source bacula-gui tar archive.

To prepare Baculum runtime files one uses the Makefile file.
To do this, after unpacking bacula-gui archive please go to Baculum main
directory:

\begin{verbatim}
cd ./web/baculum/
\end{verbatim}

Then please run (depending on used distribution):

For rpm-based distributions (example with /tmp/baculum-runtime destination
directory):

\begin{verbatim}
make build DESTDIR=/tmp/baculum-runtime
\end{verbatim}

For deb-based distributions (example with /tmp/baculum-runtime destination
directory):

\begin{verbatim}
make build DESTDIR=/tmp/baculum-release SAMPLETYPE=deb-template \
HTTPDNAME=apache2 HTTPDSITECONF=sites-available
\end{verbatim}

After execution above command, in path /tmp/baculum-runtime should
contain all required runtime files.

The Base Baculum source files will be located in:

\begin{verbatim}
/tmp/baculum-runtime/usr/share/baculum/htdocs/
\end{verbatim}

These are the files that should be placed in web server's document root (or
Virtual Host document root) directory.

Please note that for language files (including English)
symbolic links must be created as shown below:

\begin{verbatim}
/usr/share/locale/en/LC_MESSAGES/baculum.mo
 => /tmp/baculum-runtime/usr/share/baculum/htdocs/protected/Lang/en/baculum.mo

/usr/share/locale/pl/LC_MESSAGES/baculum.mo
 => /tmp/baculum-runtime/usr/share/baculum/htdocs/protected/Lang/pl/baculum.mo

/usr/share/locale/pt/LC_MESSAGES/baculum.mo
 => /tmp/baculum-runtime/usr/share/baculum/htdocs/protected/Lang/pt/baculum.mo

/usr/share/locale/ja/LC_MESSAGES/baculum.mo
 => /tmp/baculum-runtime/usr/share/baculum/htdocs/protected/Lang/ja/baculum.mo
\end{verbatim}

Please also update the symbolic link to the Baculum settings directory in
the following paths:

\begin{verbatim}
/tmp/baculum-runtime/usr/share/baculum/htdocs/protected/API/Config
/tmp/baculum-runtime/usr/share/baculum/htdocs/protected/Web/Config
\end{verbatim}

Other files are: web servers configuration files, systemd units, SELinux
policy module and others. Please select and copy appropriate files to your
system environment and edit their content if needed.

You must set read/write privileges for the Web server user
to the files and directories listed below:

\begin{verbatim}
./baculum/assets/
./baculum/protected/Web/Config
./baculum/protected/API/Config
./baculum/protected/Web/baculum.users
./baculum/protected/API/baculum.users
./baculum/protected/runtime/
\end{verbatim}

\section{OAuth2 authorization}

Baculum API can use OAuth2 for authorization and authentication.

To obtain tokens there is used {\bf Authorization Code Grant} flow.
Authorization and access token URLs are as follows:

\begin{verbatim}
Authorization URL: /api/auth/
Access Token URL: /api/token/
\end{verbatim}

Baculum API doesn't use refresh tokens. After expiration token the client
application has to re-authorize again.

Default expiration time for authorization code is 7 seconds, for access
token 60 seconds. These values are changed in:

\begin{verbatim}
/usr/share/baculum/htdocs/protected/Common/Class/OAuth2.php
\end{verbatim}

in constants AUTHORIZATION\_ID\_EXPIRES\_TIME and ACCESS\_TOKEN\_EXPIRES\_TIME.

Default OAuth2 callback URL in Baculum Web is following:

\begin{verbatim}
https://baculumgui:9095/web/redirect
\end{verbatim}

\subsection{Before running OAuth2}

{\bf Important note before using OAuth2}

When you decide to use OAuth2, you must change default HTTP Basic authorization
setting. Otherwise OAuth2 will not work. It is for enabling OAuth2 acces for
/api/ endpoints but still keep HTTP Basic protection for the Baculum API panel
pages.

For Apache the change is about switching in Baculum API Apache config
the Location tag from / to /api/page.

\begin{verbatim}
# NOTE: When you use OAuth2 then change this location section
# From: <Location />
# To:   <Location /api/page>
#
<Location />
        AuthType Basic
        AuthName "Baculum Auth"
        AuthUserFile /usr/share/baculum/htdocs/protected/API/Config/baculum.users
        Require valid-user
</Location>
\end{verbatim}


For Lighttpd the change is about uncommenting in API Lighttpd config lines as
described in comment below.

\begin{verbatim}
#
# Uncomment this line and closing braces below when you use OAuth2
#
# $HTTP["url"] =~ "^/web/page/.*$" {
        auth.backend = "htpasswd"
        auth.backend.htpasswd.userfile = "/usr/share/baculum/htdocs/protected/API/Config/baculum.users"
        auth.require = ( "/" => (
                "method" => "basic",
                "realm" => "Baculum Auth",
                "require" => "valid-user"
                )
        )
# }
\end{verbatim}
