Complete!
Start the mysqld service.
[root@linuxhelp1 ~]# service mysqld start
Initializing MySQL database: Installing MySQL system tables...
OK
Filling help tables...
OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password ' new-password'
/usr/bin/mysqladmin -u root -h linuxhelp1 password ' new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd /usr /usr/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test perl mysql-test-run.pl
Please report any problems with the /usr/bin/mysqlbug script!
[ OK ]
Starting mysqld: [ OK ]
[root@linuxhelp1 ~]# chkconfig mysqld on [root@linuxhelp1 ~]# mysqladmin -u root password linuxc

#
Director {
Name = bacula-dir
Password = " linuxc"
}
.
.
.
Device {

}
change the directory entry and remove the previous entry
Create a directory called “ mybackup” .
[root@linuxhelp1 ~]# mkdir /mybackup [root@linuxhelp1 ~]# chown bacula /mybackup/
Restart all the bacula daemons and allow them to start automatically on every reboot.
[root@linuxhelp1 ~]# service bacula-dir start Starting bacula-dir: [ OK ] [root@linuxhelp1 ~]# service bacula-fd start Starting bacula-fd: [ OK ] [root@linuxhelp1 ~]# service bacula-sd start Starting bacula-sd: [ OK ] [root@linuxhelp1 ~]# chkconfig bacula-dir on [root@linuxhelp1 ~]# chkconfig bacula-fd on [root@linuxhelp1 ~]# chkconfig bacula-sd on
To manage Bacula With Webmin

To Connect Webmin
Dive into the browser and enter “ //http://< ip_address> :10000” or “ http://< domain_name> :10000/”
Go to System &rarr Bacula Backup System to backup your datas.
The Bacula server cannot start automatically. Click on “ Module Configuration” link on the “ Bacula Backup System” page.
Select the database type and fill the bacula database user and password. Then click Save.
Q
How can I force one job to run after another?
A
Yes, you can set Priorities on your jobs so that they run in the order you specify.
Q
What is Bacula?
A
Bacula is a set of computer programs that permits the system administrator to manage backup, recovery, and verification of computer data across a network of computers of different kinds. Bacula can also run entirely upon a single computer and can backup to various types of media, including tape and disk.In technical terms, it is a network Client/Server based backup program.
Q
Does Bacula support Windows?
A
Yes, Bacula compiles and runs on Windows machines (Win98, WinMe, WinXP, WinNT, Win2003, and Win2000). We provide a binary version of the Client (bacula-fd), but have not tested the Director nor the Storage daemon. Note, Win95 is no longer supported because it doesn't have the GetFileAttributesExA API call.
Q
On what machines does Bacula run?
A
Bacula builds and executes on Red Hat Linux (versions RH7.1-RHEL 4.0, Fedora, SuSE, Gentoo, Debian, Mandriva, ...), FreeBSD, Solaris, Alpha, SGI (client), NetBSD, OpenBSD, Mac OS X (client), and Win32.
Bacula has been my only backup tool for over seven years backing up 8 machines nightly (6 Linux boxes running SuSE, previously Red Hat and Fedora, a WinXP machine, and a WinNT machine).

Q
How to stop a job in Bacula?
A
you normally should use the Console command cancel to cancel a Job that is either scheduled or running. If the Job is scheduled, it will be marked for cancellation and will be canceled when it is scheduled to start. If it is running, it will normally terminate after a few minutes. If the Job is waiting on a tape mount, you may need to do a mount command before it will be canceled.
