Tutorial Linux Indonesia : Bacula

Install Bacula Server di CentOs 7

Tutorial linux Indonesia -- Bacula merupakan solusi backup yang opensource yang memungkinkan kita sebagai sysadmin, untuk melakukan backup data server kita.

Install Bacula Server di Centos 7

Melakukan pemulihan data atau restore data server kita, apabile server kita sedang bermasalah.

Hal ini sangat fleksibel dan sangat efisien. Sangat cocok untuk melakukan backup dalam banyak situasi.

Sebuah sistem backup merupakan komponen penting dalam infrastuktur server, untuk menghindari kehilangan data penting.

Apabila server kita mengalami masalah atau server kita terkena hacker. Untuk mengatasi masalah server tersebut.

Ternyata solusi terbaik untuk server tersebut adalah install ulang server, data server yang sebelum sudah berhasil di backup dapat di lakukan restore atau pemulihan data server tersebut.

Dalam tutorial ini, bagol69 akan menunjukan cara instalasi Bacula dan konfigurasi Bacula pada centos 7.

Sekarang kita install paket-paket yang mendukung untuk bacula.

[root@bagol69 ~]# yum install bacula-director-mysql bacula-console bacula-client bacula-storage-mysql mysql-server mysql-devel -y

Aktifkan servis database kita. Untuk saat ini bagol69 menggunakan database mysql.

[root@bagol69 ~]# services mysqld start

[root@bagol69 ~]#chkconfig mysqld on

Buat password untuk akses database mysql.

[root@bagol69 ~]# mysqladmin -u root password bagol69

Silahkan anda import database bacula ke database server anda.

[root@bagol69 ~]# /usr/libexec/bacula/grant_mysql_privileges -u root -p

[root@bagol69 ~]# /usr/libexec/bacula/create_mysql_database -u root -p

[root@bagol69 ~]# /usr/libexec/bacula/make_mysql_tables -u root -p

[root@bagol69 ~]# /usr/libexec/bacula/grant_bacula_privileges -u root –p

[root@bagol69 ~]# /usr/libexec/bacula/grant_mysql_privileges -u root –p

Sekarang update password untuk user bacula di server database anda.

[root@bagol69 ~]# mysql -u root -p

Enter password:

mysql> UPDATE mysql.user SET password=PASSWORD

("bagol69") WHERE user='bacula';

Query OK, 2 rows affected (0.00 sec)

Rows matched: 2 Changed: 2 Warnings: 0

mysql> FLUSH PRIVILEGES;

Query OK, 0 rows affected (0.01 sec)

mysql> exit

Bye

Cara Melakukan Backup dan Restore Container Docker

Cara Memberikan nama pada Container Docker

Sekarang kita sudah masuk ke folder utama bacula. Ada beberapa parameter yang di konfigurasi.

[root@bagol69 ~]# nano /etc/bacula/bacula-dir.conf

Anda berikan password untuk console bacula. Yang saya berikan highlight kuning.

Director { # define mysel

Name = bacula-dir

DIRport = 9101 # where we listen for UA connections

QueryFile = "/usr/libexec/bacula/query.sql"

WorkingDirectory = "/var/spool/bacula"

PidDirectory = "/var/run"

Maximum Concurrent Jobs = 1

Password = "bagol69" # Console password

Messages = Daemon

}

Tambahkan perintah GZIP, supaya hasil backup data secara otomatis akan di gunzip.

# List of files to be backed up

FileSet {

Name = "Full Set"

Include {

Options {

signature = MD5

Compression = GZIP

Anda berikan ip address dari server yang ingin lakukan backup data dan berikan password untuk file daemon tersebut.

# Client (File Services) to backup

Client {

Name = bacula-fd

Address = 10.10.10.1

FDPort = 9102

Catalog = MyCatalog

Password = "bagol69" # password for FileDaemon

File Retention = 30 days # 30 days

Job Retention = 6 months # six months

AutoPrune = yes # Prune expired Jobs/Files

}

Untuk parameter ini, berfungsi untuk memberikan format pada file backup.

# Client (File Services) to backup

Client {

Name = bacula-fd

Address = 10.10.10.1

FDPort = 9102

Catalog = MyCatalog

Password = "bagol69" # password for FileDaemon

File Retention = 30 days # 30 days

Job Retention = 6 months # six months

AutoPrune = yes # Prune expired Jobs/Files

}

Anda berikan alamat ip address dari server storage ( Bacula –server ). Berikan password untuk server storage tersebut.

Storage {

Name = File

# Do not use "localhost" here

Address = 10.10.10.1

SDPort = 9103

Password = "bagol69"

Device = FileStorage

Media Type = File

}

Sekarang anda isikan informasi database yang sudah anda buat sebelumnya untuk server bacula.

# Generic catalog service

Catalog {

Name = MyCatalog

# Uncomment the following line if you want the dbi driver

# dbdriver = "dbi:sqlite3"; dbaddress = 127.0.0.1; dbport =

dbname = "bacula"; dbuser = "bacula"; dbpassword = "bagol69"

Pada file bconsole.conf berikan alamat ip address dari server bacula dan password server bacula tersebut.

[root@bagol69 ~]# nano /etc/bacula/bconsole.conf

Silahkan anda ubah settingan, tinggal sesuaikan saja dengan kondisi server.

Director {

Name = bacula-dir

DIRport = 9101

address = 10.10.10.1

Password = "bagol69"

}

Silahkan anda masukan command yang saya berikan tanda highlight untuk melakukan backup database.

[root@bagol69 ~]# nano /usr/libexec/bacula/make_catalog_backup.pl

exec("HOME='$wd' mysqldump -f -u$args{db_user} -p$args{db_password} --opt $args{db_name} > '$wd/$args{db_name}.sql'");

close(MY);

# exec("HOME='$wd' mysqldump -f --opt $args{db_name} > '$wd/$args{db_name}.sql'");

exec("HOME='$wd' mysqldump -f -u$args{db_user} -p$args{db_password} --opt $args{db_name} > '$wd/$args{db_name}.sql'");

print "Error while executing mysql dump $!\n";

return 1;

}

Sekarang anda restart services bacula mengunakan perintah di bawah ini.

[root@bagol69 ~]# /etc/init.d/bacula-dir restart

Shutting down bacula-dir: [ OK ]

Starting bacula-dir: [ OK ]

[root@bagol69 ~]# /etc/init.d/bacula-dir start

Starting bacula-dir: [ OK ]

[root@bagol69 ~]# chkconfig bacula-dir on

[root@bagol69 ~]#

Sekarang kita konfigurasi folder yang menyimpan hasil backup dari server client.

Secara otomatis hasil backup akan menyimpan di folder /tmp, jika server di restart isi dari folder /tmp akan hilang.

Oleh karena itu kita arahkan hasil backup dari bacula ke folder yang kita buat sendiri.

[root@bagol69 ~]# nano /etc/bacula/bacula-sd.conf

Anda berikan password untuk bacula-sd.

Director {

Name = bacula-dir

Password = "bagol69"

}

Silahkan anda setting untuk tempat menyimpan hasil dari backup server anda.

Device {

Name = FileStorage

Media Type = File

Archive Device = /mybackup

LabelMedia = yes; # lets Bacula label unlabeled media

Random Access = Yes;

AutomaticMount = yes; # when device opened, read it

RemovableMedia = no;

AlwaysOpen = no;

}

Sekarang anda buat folder untuk menyimpan hasil d ari backup tersebut. Silahkan anda atur permission dan hak akses folder tersebut.

[root@bagol69 ~]# mkdir /mybackup/

[root@bagol69 ~]# chown bacula /mybackup/

[root@bagol69 ~]# ls -lah /mybackup/

total 16K

drwxr-xr-x. 2 bacula root 4.0K Jul 28 00:37 .

Buat password untuk bacula-fd

[root@bagol69 ~]# nano /etc/bacula/bacula-fd.conf

Director {

Name = bacula-dir

Password = "bagol69"

}

Sekarang anda restart services bacula-server menggunakan command di bawah ini.

[root@bagol69 ~]# service bacula-dir start

Starting bacula-dir: [ OK ]

[root@bagol69 ~]# service bacula-fd start

Starting bacula-fd: [ OK ]

[root@bagol69 ~]# service bacula-sd start

Starting bacula-sd: [ OK ]

[root@bagol69 ~]# chkconfig bacula-dir on

[root@bagol69 ~]# chkconfig bacula-fd on

[root@bagol69 ~]# chkconfig bacula-sd on

[root@bagol69 ~]#

Password = "bagol69

Untuk memudahkan management bacula-server. Kami sarankan untuk install webmin untuk management server backup.

Sekarang anda download terlebih dahulu webmin, menggunakan command di bawah ini.

[root@bagol69 ~]# wget --no-check-certificate http://sourceforge.net/projects/webadmin/files/webmin/1.660/webmin-1.660-1.noarch.rpm

Setelah selesai download webmin, anda dapat instalasi webmin menggunakan command di bawah ini.

[root@bagol69 ~]# rpm -Uvh webmin-1.660-1.noarch.rpm

Anda Restart dan aktifkan services webmin.

[root@bagol69 ~]# service webmin start

[root@bagol69 ~]# chkconfig webmin on

Secara default, CentOs mengaktifkan firewall iptables untuk mengamanakan server.

Semua traffic dan s emua port secara default akan di drop. Silahkan anda stop services iptables, supaya port webmin bisa di akses.

[root@bagol69 ~]# service iptables stop

[root@bagol69 ~]# chkconfig iptables off

Anda dapat akses webmin menggunakan link tersebut.

https://alamatipanda:10000

https://namadomainanda:10000

Untuk login ke webmin, mengunakan password dari server anda.

Install Bacula Server di Centos 7

Untuk mengaktifkan Services bacula di webmin, silahkan anda pergi ke menu system à Bacula Backup System.

Install Bacula Server di Centos 7

Sekarang anda berikan informasi database untuk server bacula.

Untuk melakukan backup data di sisi server, bisa menggunakan command bconsole.
