About this manual

The basic features of Webacula see in README file.

This manual should give you to install or upgrade Webacula installation.

If you find errors or typos please send a bug report.

Thanks.

Webacula has a number of email lists. For general information subscribing to or unsubscribing from these lists, please see Webacula Mailing Lists at SourceForge.

System Requirements

To check the installed system packages, run from command line:

docs/check_system_requirements.php

NOTE. The successful execution of the script does not indicate that your system is fully ready to work with Webacula.

Webacula also requires:

Bacula 5.0 or later
Zend Framework version 1.10.0 or later
Zend Framework is built with object-oriented PHP 5 and requires PHP 5.2.4 or later with PDO extension active. Please see the system requirements appendix for more detailed information.
Apache and mod_rewrite. Or equivalent web-server, for example, nginx and ngx_http_rewrite_module
Installed php-gd package
Installed http://php.net/dom for use the RSS feed
Browser compatibility: all jQuery UI plugins are tested for IE 6.0+, Firefox 3+, Safari 3.1+, Opera 9.6+, Google Chrome

Install

Make directory tree

Download minimal Zend Framework package and extract. Copy the contents from directory
ZendFramework-*-minimal/library/Zend
to
webacula/library/Zend

NOTE. If you use the Zend Framework for multiple sites, then you can place it in a folder that is part of your PHP include path. By doing this, you will have access to the Zend Framework components in all PHP scripts.

The tree which should turn out as a result :

/var/www/webacula/
|-- application
|   |-- controllers
|   |-- models
|   `-- views
...
|-- data
|   `-- cache
...
|-- docs
|-- install
|-- html
|-- languages
`-- library
    |-- MyClass
    `-- Zend (here is Zend Framework package)
        |-- Acl
        |-- Auth
        |-- Cache
       ...

PHP session is stored in the table webacula_php_session.

Some directory description:

application/ All source code. Should be available to reading for the Web-server and no access through the client Web-browser.

html/ Public code. Should be available to reading for the Web-server and for the client Web-browser.

data/ IMPORTANT. This directory, subdirectory and files in it must NOT be available to access through the client Web-browser.

data/cache/ Cache directory for Zend_Cache. Should be available to writing the Web-server and no access through the client Web-browser.

config.ini

Specify the parameters to connect to the Catalog database, timezone and other in application/config.ini

Setting up to run bconsole under Webacula

Create system group account (if not yet created) :
groupadd bacula

Add apache to group:
usermod -aG bacula apache

IMPORTANT. Check /usr/sbin/bconsole it should be the binary ELF file, not a shell script!

Next, setup bconsole can be executed under Apache webserver.

Without using sudo

chown root:bacula /usr/sbin/bconsole
chmod u=rwx,g=rx,o=  /usr/sbin/bconsole

chown root:bacula /etc/bacula/bconsole.conf
chmod u=rw,g=r,o= /etc/bacula/bconsole.conf

Edit application/config.ini

bacula.sudo = ""
bacula.bconsole = "/usr/sbin/bconsole"

With sudo

Edit application/config.ini

bacula.sudo = "/usr/bin/sudo"
bacula.bconsole = "/usr/sbin/bconsole"

Run visudo and changes

# (!!! comment here !!!) Defaults requiretty
apache ALL=NOPASSWD: /usr/sbin/bconsole

Check out the run bconsole :

# su -l apache -s /bin/sh \
     -c "/usr/bin/sudo /usr/sbin/bconsole -n -c /etc/bacula/bconsole.conf"

Apache

Configuration for Apache see in install/apache/webacula.conf file.

NOTE. Specific directories on your system may be different.

Next, restart your Webserver.

mod_rewrite

Setup mod_rewrite see html/.htaccess. Edit RewriteBase parameter if necessary.

NOTE. Specific directories on your system may be different.

Check mod_rewrite installed :

$ apachectl -t -D DUMP_MODULES 2>&1 | grep rewrite

rewrite_module (shared)

For testing mod_rewrite change RewriteBase parameter, if necessary, in webacula/html/test_mod_rewrite/.htaccess file.

And use URL like http://localhost/webacula/test_mod_rewrite/ for test mod_rewrite.

PHP

Increase values in /etc/php.ini :

memory_limit = 32M
max_execution_time = 3600

Bacula setup

To show messages of the Job output, you must make changes in bacula-dir.conf file :

Messages {
  Name = Standard
  ...
  catalog = all, !skipped, !saved
}

and restart Bacula Director.

See also manual of Bacula "Chapter 15. Messages Resource".

Webacula install

If necessary change settings in install/db.conf file.

IMPORTANT. Change passwords in a file install/db.conf.

Next create Webacula tables, Webacula built-in roles and Webacula built-in users.

For MySQL:

cd install/MySql

For PostgreSQL:

cd install/PostgreSql

For Sqlite:

cd install/SqLite

And further run scripts for your DBMS is running on localhost:

./10_make_tables.sh
./20_acl_make_tables.sh

If your DBMS is running on a remote host, specify the appropriate option on the command line, for example, MySQL:

./10_make_tables.sh      --host my.domain.tld
./20_acl_make_tables.sh  --host my.domain.tld

Change file html/.htaccess :

SetEnv APPLICATION_ENV production
RewriteBase   /webacula

After that, you can login under the superuser root and the password which specified in a file install/db.conf in parameter webacula_root_pwd.

Webacula setup

Webacula and Bacula ACLs

Bacula ACLs -- Bacula Console Access Control List -- it is necessary to understand as it is described in the original documentation in section ''Bacula Main Reference'', ''Configuring the Director'', ''The Console Resource''.

In Webacula are implemented following Bacula ACLs :

JobACL
ClientACL
StorageACL
PoolACL
FileSetACL
WhereACL

Special keyword *all* when is present, any resource or command name will be accepted.

Webacula ACLs -- it as a matter of fact access to certain menu items of Webacula.

**Figure 1:** Webacula ACLs

If the user (more precisely -- a role) does not have any a ACL rule, that user has no rights.

ACL rules are applied in the order which is defined by field value ''order''.

Bacula and Webacula ACLs can conflict. For example, usage of a Bacula command status is allowed to the user, but access to Webacula menu item Director at the same time is forbidden.

In this case the user sees the message like :

You try to use Webacula menu "director".
Webacula ACLs : Access denied.

And on the contrary. Access to Webacula menu item Director can be allowed. And usage of a Bacula command status can be forbidden.

In this case the user sees the message like :

You try to run Bacula Console with command "status".
Bacula ACLs : Access denied.

NOTE. Pay attention that in the first case access has been forbidden by a Webacula ACL rule, and in the second a Bacula ACL rule.

Users and roles

In Webacula the concept of users and roles is used. Each user has the role. There is no user without a role.

In other words you should create a role at first, and then create the user and assign to it a certain role.

The role can inherit from other role.

After install, Webacula has two built in roles :

root_role -- default built-in superuser role.
operator_role -- typical built-in role for backup operator.

Users by whom the role root_role is assigned are superusers, they have all rights to all. This role cannot be deleted and the role name cannot be changed.

After installation root_role is assigned to the user with a login name root.

The role operator_role can fulfill any operations except of the administarators functions : creation, change, assignment of roles, users.

Update from prior version

IMPORTANT. Now there is no separate Webacula database. All Webacula tables are allocated in a Bacula database and have a prefix webacula_.

Therefore, if you conducted Webacula LogBook, you need to take care to transfer wbLogBook table to a Bacula database in webacula_logbook table.

Precisely also transfer the data from Webacula database wbJobDesc table to Bacula database to table webacula_jobdesc.

For example

-- old Webacula database
USE webacula;
SELECT * FROM wbJobDesc INTO OUTFILE '/tmp/webacula_wbJobDesc';
SELECT * FROM wbLogBook INTO OUTFILE '/tmp/webacula_wbLogBook';

-- now Bacula database
USE bacula;
LOAD DATA INFILE '/tmp/webacula_wbJobDesc' INTO TABLE webacula_jobdesc;
LOAD DATA INFILE '/tmp/webacula_wbLogBook' INTO TABLE webacula_logbook;

From a file config.ini delete from [webacula] sections lines with the connection description to a Webacula database.

Also remove tmpdir from config.ini, is not necessary now.

The script webacula_clean_tmp_files.sh is not necessary now.
