7) bweb limitation
8) using sudo with autochanger
9) using bfileview.pl
10) accessing to bweb
11) setting mysql read-only account
12) get more statistics
13) use groups with bweb
14) setup restoration in bweb (not yet working)
################ FILE COPY #####################################
# you must get bweb svn files
svn checkout https://bacula.svn.sourceforge.net/svnroot/bacula/trunk/gui/bweb bweb
# or get them from the released tar files or from the apt or rpms.
#
# Once you have the gui directory loaded, follow the instructions below
# or edit the environment variables in the file install_bweb
# then execute it. install_web does everything to the next
# set of #######'s.
#
# first, copy the bweb Perl library into your PERL5 INC path
perl Makefile.PL
make install
# or
install -m 644 -o root -g root bweb/lib/*.pm /usr/share/perl5
# copy the bweb perl program to your cgi location
mkdir -m 755 /usr/lib/cgi-bin/bweb
install -m 755 -o root -g root bweb/cgi/*.pl /usr/lib/cgi-bin/bweb
# get a config file
mkdir -m 755 /etc/bacula
chown root:bacula /etc/bacula
echo '$VAR1 = { template_dir => "/usr/share/bweb/tpl" };' > /etc/bacula/bweb.conf
chown www-data /etc/bacula/bweb.conf
# copy the bweb template file
mkdir -p /usr/share/bweb/tpl
install -m 644 -o root -g root bweb/tpl/*.tpl /usr/share/bweb/tpl
# copy the bweb graphics elements (bweb elements must reside in /bweb)
mkdir /var/www/bweb
install -m 644 -o root -g root bweb/html/*.{js,png,css,gif,ico,html} /var/www/bweb
# done !
WARNING : Your www-data (or wwwrun on SuSE) user must be able to execute bconsole and able
to read the bconsole.conf file!
You can create an bconsole group for that.
################ USE FRENCH VERSION ############################
Simply use lang/fr/tpl/*.tpl files instead of tpl/*.tpl
################ INSTALL PERL LIBRARY ##########################
- perl modules
- DBI (with mysql or postgresql support DBD::Pg and DBD::mysql)
(SQLite is not supported)
- GD::Graph
- GD
- HTML::Template
- CGI
- Expect
- Time::ParseDate
- Date::Calc
You can install perl modules with CPAN
perl -e shell -MCPAN
> install Expect
Or use your distribution
apt-get install libgd-graph-perl libhtml-template-perl libexpect-perl \
libdbd-mysql-perl libdbd-pg-perl libdbi-perl \
libdate-calc-perl libtime-modules-perl
Note: the best way to test if you have all the dependencies
fullfilled for Perl is to:
cd /var/www/cgi-bin/bweb
./bweb.pl
you might also want to try:
./bgraph.pl
To make sure the graphing modules are loaded. However, running it
will spray binary graphics data on your terminal. Otherwise, you will
get an error.
That should show you if any of the pre-requisites are missing.
On SuSE 10.2, I was able to load all the appropriate modules via rpms,
with the exception of Expect and Time::ParseDate, which I loaded manually
using perl.
If you experience problems, always consult the Apache error_log
file.
################ APACHE CONFIGURATION ##########################
It could be a good idea to protect your bweb installation (optional).
Put this in your httpd.conf, and add user with htpasswd
Options ExecCGI -MultiViews +SymLinksIfOwnerMatch
AuthType Basic
AuthName MyPrivateFile
AuthUserFile /etc/apache/htpasswd
AllowOverride None
Require valid-user
On SuSE 10.2, the following in /etc/apache2/default-server.conf works.
However, it is not secure:
Directory "/srv/www/cgi-bin/bweb">
AllowOverride None
Options +ExecCGI -Includes
Order allow,deny
Allow from all
################ CONFIGURATION #################################
Note, this is automatically installed by the install_bweb script.
/etc/bacula/bweb.conf looks like : (you can edit it inside bweb)
$VAR1 = bless( {
'graph_font' => '/usr/share/fonts/truetype/ttf-bitstream-vera/Vera.ttf',
'name' => undef,
'config_file' => '/etc/bacula/bweb.conf',
'bconsole' => '/usr/sbin/bconsole -n -c /etc/bacula/bconsole.conf',
'ach_list' => {
'S1_L80' => bless( {
'info' => {
'drive' => 0,
'io' => 0,
'slot' => 0
},
'name' => 'S1_L80',
'bweb' => undef,
'device' => '/dev/changer',
'drive' => [],
'debug' => 0,
'label' => {},
'precmd' => 'sudo',
'io' => [],
'mtxcmd' => '/usr/sbin/mtx',
'drive_name' => [
'S1_L80_SDLT0',
'S1_L80_SDLT1'
],
'slot' => []
}, 'Bweb::Autochanger' )
},
'password' => 'xxx',
'template_dir' => '/usr/share/bweb/tpl',
'dbi' => 'DBI:mysql:database=bacula',
'error' => '',
'debug' => 0,
'user' => 'bacula',
'email_media' => 'eric@localhost'
}, 'Bweb::Config' );
################ BRESTORE ######################################
If you want to use brestore with bweb, you must associate a mime type
text/brestore with your brestore.pl, and you must install brestore.
See gui/brestore/README for instructions on installing brestore.pl.
################ POSTGRESQL AND MYSQL5 NOTES ####################
If you want to use PostgreSQL instead of MySQL, you must add
a function to the PostgreSQL Bacula database to get Bweb to work.
psql -U bacula bacula < script/bweb-postgresql.sql
Tips: PL must be enabled in your cluster, you can do this with postgres user
postgres:~$ echo 'CREATE PROCEDURAL LANGUAGE plpgsql;' | psql bacula
To get database size with mysql5, edit Bweb.pm and change the DB_SIZE macro
# with mysql < 5, you have to play with the ugly SHOW command
DB_SIZE => " SELECT 0 ",
# works only with mysql 5
# DB_SIZE => " SELECT sum(DATA_LENGTH) FROM INFORMATION_SCHEMA.TABLES ",
################ BCONSOLE NOTES ################################
You must use bconsole without conio/readline support. For that, use
the bconsole -n option. This is done automatically with the standard
configuration file. In addition, please ensure that the binary
bconsole file can be executed by your web server. It is normally
located in /usr/bin/bconsole (or some such file), and must have
modes 755 or it will not be executable by your web server. The
normal Bacula installation usually sets mode 750.
################ BACULA LOG ####################################
If you want Bweb to be able to show listings of the Job output,
you must add a "catalog = all, !skipped, !saved" to your
messages resource in bacula-dir.conf and restart your Bacula
server. This is shown below:
Messages {
Name = Standard
operator = root@localhost = mount
console = all, !skipped, !saved
append = "/tmp/bacula/var/bacula/working/log" = all, !skipped
catalog = all, !skipped, !saved
}
################ BWEB LIMITATION ###############################
To get bweb working, you must follow these rules
- Media, Storage and Pool must have [A-Za-z_0-9\.-]+ (no space)
- AutoChanger name must be same as Device and Location name in bacula
################ SUDO CONFIGURATION ############################
If you use sudo, put this on you /etc/sudoers
www-data ALL = (root) NOPASSWD: /usr/sbin/mtx -f /dev/changer transfer *
www-data ALL = (root) NOPASSWD: /usr/sbin/mtx -f /dev/changer status
www-data ALL = (root) NOPASSWD: /usr/sbin/mtx -f /dev/changer load *
www-data ALL = (root) NOPASSWD: /usr/sbin/mtx -f /dev/changer unload *
################ BFILEVIEW SETUP ###############################
At this time, bfileview works only with PostgreSQL.
Alias /bweb/fv /var/spool/bweb
Options None
AllowOverride AuthConfig
Order allow,deny
Allow from all
mkdir /var/spool/bweb
chmod 700 /var/spool/bweb
chown www-data /var/spool/bweb
You have to remove "" from
tpl/display_job_zoom.tpl.
You MUST use brestore.pl -b to initialize the database, and
you CAN use bfileview.pl mode=batch jobid=xxx where=/ to compute tree size.
At this time, it's a good idea to schedule brestore.pl -b after your
BackupCatalog job.
Job {
Name = "BackupCatalog"
...
# This creates an ASCII copy of the catalog
RunBeforeJob = "/opt/bacula/etc/make_catalog_backup bacula bacula Pei0ahm9"
# This deletes the copy of the catalog
RunAfterJob = "/opt/bacula/etc/delete_catalog_backup"
RunAfterJob = "/usr/local/bin/brestore.pl -b"
}
To upgrade from an old installation, you can use :
ALTER TABLE brestore_pathvisibility ADD Size int8;
ALTER TABLE brestore_pathvisibility ADD Files int4;
################ ACCESSING TO BWEB ############################
Now, you are able to launch firefox/mozilla and go on
http://your-server/bweb
################ SETTING MYSQL ACCOUNT ########################
At this time, Bweb needs a write access to :
- Location
- LocationLog
- Media::LocationId
- Media::Comment
- Media::RecyclePoolId (it will change soon)
If your doesn't use Location feature, you can use ReadOnly access
for all tables, or setup something like :
GRANT SELECT ON bacula.* TO 'bweb'@'%' IDENTIFIED BY 'password';
GRANT INSERT,UPDATE,DELETE ON bacula.Location
TO 'bweb'@'%' IDENTIFIED BY 'password';
GRANT INSERT,UPDATE,DELETE ON bacula.LocationLog
TO 'bweb'@'%' IDENTIFIED BY 'password';
################ GET MORE STATISTICS ###########################
You keep Jobs informations across retention into a job_old table.
You have to setup stat_job_table = job_old in bweb configuration.
CREATE TABLE job_old (LIKE Job);
And run this on crontab when you want :
INSERT INTO job_old
(SELECT * FROM Job WHERE JobId NOT IN (SELECT JobId FROM job_old) );
################ USE GROUPS WITH BWEB ##########################
It works with postgresql and mysql5 (4 not tested).
With mysql, load bweb/script/bweb-mysql.sql into your catalog
For postgresql, it will be done with bweb/script/bweb-postgresql.sql (already done)
################ MADE RESTORATION WITH BWEB ####################
Warning, this function is not for production use at this time !
It will do some basics things on a working bweb/brestore setup.
1) Go to http://extjs.com and download their toolkit (last 1.X release)
2) Install files in /bweb/ext web root
example on debian :
root@localhost:~# mv ext-1.1.1 /usr/share/bweb/html/ext
3) Make sure that brestore cache tables are updated with brestore.pl
bacula@localhost:~$ brestore.pl -b
4) Enable bresto.pl cgi.
edit the bweb/cgi/bresto.pl script and change $bresto_enable=0; to $bresto_enable=1;
on the top of the file.
5) Use the last Bweb.pm
If you are trying bresto in a working bweb/brestore setup, you must make sure that you use
the last Bweb.pm SVN version.
6) Go on http://you-director/bweb/bresto.html
