Install Bacula on CentOS 8 | CentOS 7

In this section, we will discuss how to install Bacula on CentOS 8. Note that Bacula can work with the PostgreSQL database management system. So it is enough to do the following steps in order:

dnf install postgresql-server

postgresql-setup initdb

systemctl enable --now postgresql

The next step is to create a user for Bacula. To do this, run the following commands in order:

sudo su - postgres

$ createuser bacula

$ psql

psql (10.14)

Type "help" for help.

postgres=# ALTER USER bacula PASSWORD 'bacula';

ALTER ROLE

postgres=# ALTER USER bacula LOGIN SUPERUSER CREATEDB CREATEROLE;

ALTER ROLE

postgres=# \q

$ exit

logout

Now you should uncomment the following setting in the /var/lib/pgsql/data/postgresql.conf file:

listen_addresses = 'localhost'

Now you need to change the connection configuration to the following format in the /var/lib/pgsql/data/pg_hba.conf file:

Finally, you must restart the service using the following command to apply the changes:

systemctl restart postgresql.service

After you have successfully installed Postgresql, now we come to the installation of Bacula. The first step is to install the Bacula components using the following commands:

dnf install bacula-director bacula-storage bacula-console bacula-client

You can create databases, tables, and privileges by following the instructions below. Note that you must run them on behalf of the newly created Bacula user:

cd /usr/libexec/bacula/

sudo -u bacula ./create_postgresql_database

sudo -u bacula ./make_postgresql_tables

sudo -u bacula ./grant_postgresql_privileges

After successfully completing the previous step, you should now open the /etc/bacula/bacula-sd.conf file and set Archive Device = /opt/bacula for both Devices:

Device {  ...  Archive Device = /opt/bacula  ...  }

You can now start the service using the following commands:

systemctl enable --now bacula-dir.service

systemctl enable --now bacula-fd.service
