Building Bareos RPMs on CentOS 6 & 7

Bareos (Backup Archiving Recovery Open Sourced) is a popular open source backup system originally forked from the Bacula project, but they only publicly publish packages for the first release of each major version; updates are reserved for paying customers. The source code is available on GitHub however, so you can pretty easily build your own packages, even if exactly how to do it doesn’t seem to be documented.

These instructions are based on Bareos version 17.2.5, so would need to be adjusted appropriately for other versions. I’m also working exclusively with 64-bit (x86_64) versions.

Before we start, lets make sure that everything is up to date:

yum -y update

If you don’t already have the EPEL repository installed, then install it as we’ll need it for the jansson-devel and libcmocka-devel build dependancies:

yum -y install  epel-release

Now install everything needed to build the RPMs. We’ll use the libdroplet, libdroplet-devel, libfastlz and libfastlz-devel packages from the Bareos repositories.

On CentOS 6:

yum -y install rpm-build wget autoconf automake httpd httpd-devel glusterfs-devel glusterfs-api-devel git-core gcc gcc-c++ glibc-devel ncurses-devel readline-devel libstdc++-devel zlib-devel openssl-devel libacl-devel lzo-devel sqlite-devel mysql-devel postgresql-devel libcap-devel mtx qt-devel libcmocka-devel python-devel python-setuptools libtermcap-devel tcp_wrappers redhat-lsb jansson-devel tcp_wrappers-devel http://download.bareos.org/bareos/release/17.2/CentOS_6/x86_64/libdroplet-3.0.git.1510141874.bc2a9a0-41.1.el6.x86_64.rpm http://download.bareos.org/bareos/release/17.2/CentOS_6/x86_64/libdroplet-devel-3.0.git.1510141874.bc2a9a0-41.1.el6.x86_64.rpm http://download.bareos.org/bareos/release/17.2/CentOS_6/x86_64/libfastlz-0.1-7.3.el6.x86_64.rpm http://download.bareos.org/bareos/release/17.2/CentOS_6/x86_64/libfastlz-devel-0.1-7.3.el6.x86_64.rpm

On CentOS 7:

yum -y install rpm-build wget autoconf automake httpd httpd-devel glusterfs-devel glusterfs-api-devel git-core gcc gcc-c++ glibc-devel ncurses-devel readline-devel libstdc++-devel zlib-devel openssl-devel libacl-devel lzo-devel sqlite-devel mysql-devel postgresql-devel libcap-devel mtx qt-devel libcmocka-devel python-devel python-setuptools libtermcap-devel tcp_wrappers redhat-lsb jansson-devel tcp_wrappers-devel http://download.bareos.org/bareos/release/17.2/CentOS_6/x86_64/libdroplet-3.0.git.1510141874.bc2a9a0-41.1.el6.x86_64.rpm http://download.bareos.org/bareos/release/17.2/CentOS_7/x86_64/libdroplet-devel-3.0.git.1510141874.bc2a9a0-41.1.el7.x86_64.rpm http://download.bareos.org/bareos/release/17.2/CentOS_7/x86_64/libfastlz-0.1-7.3.el7.x86_64.rpm http://download.bareos.org/bareos/release/17.2/CentOS_7/x86_64/libfastlz-devel-0.1-7.3.el7.x86_64.rpm

It’s a good idea to run the build under an unprivileged user. I’ve set up a dedicated user called “build” for this, but any normal user account will do.
Let’s set up the build environment and download the Bareos source code from the various repositories on GitHub:

useradd build
su – build
mkdir -p ~/rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
echo ‘%_topdir %(echo $HOME)/rpmbuild’ > ~/.rpmmacros
wget https://github.com/bareos/bareos/archive/Release/17.2.5.tar.gz -O bareos-17.2.5.tar.gz
tar xf bareos-17.2.5.tar.gz
mv bareos-Release-17.2.5/ bareos-17.2.5
tar zcf bareos-17.2.5.tar.gz bareos-17.2.5
mv bareos-17.2.5/platforms/packaging/bareos.spec ~/rpmbuild/SPECS/
rm -rf bareos-17.2.5
mv bareos-17.2.5.tar.gz ~/rpmbuild/SOURCES/
wget https://github.com/bareos/bareos-webui/archive/Release/17.2.5.tar.gz -O bareos-webui-17.2.5.tar.gz
mv 17.2.5.tar.gz bareos-webui-17.2.5.tar.gz
tar xf bareos-webui-17.2.5.tar.gz
mv bareos-webui-Release-17.2.5/ bareos-webui-17.2.5
tar zcf bareos-webui-17.2.5.tar.gz bareos-webui-17.2.5
mv bareos-webui-17.2.5/packaging/obs/bareos-webui.spec ~/rpmbuild/SPECS/
rm -rf bareos-webui-17.2.5
mv bareos-webui-17.2.5.tar.gz ~/rpmbuild/SOURCES/
wget https://github.com/bareos/python-bareos/archive/Release/17.2.5.tar.gz -O python-bareos-17.2.5.tar.gz
tar xf python-bareos-17.2.5.tar.gz
mv python-bareos-Release-17.2.5/ python-bareos-17.2.5
tar zcf python-bareos-17.2.5.tar.gz python-bareos-17.2.5
mv python-bareos-17.2.5/packaging/python-bareos.spec ~/rpmbuild/SPECS/
rm -rf python-bareos-17.2.5
mv python-bareos-17.2.5.tar.gz ~/rpmbuild/SOURCES/

Edit the ~/rpmbuild/SPECS/bareos.spec file in your favourite text editor and set “Version” (line 8) to “17.2.5” as well as “Release” (line 9) to “0%{?dist}”.
You also need to search for “BuildRequires: libqt4-devel” (line 186) and replace it with “BuildRequires: qt-devel”.

By default, GlusterFS and Droplet support isn’t built on CentOS 6 for some reason, so if you want them then you need to edit “%define glusterfs 0” and “%define objectstorage 0” (lines 45 and 46) and set them to 1.

Now you’d ready to run the build itself. On CentOS 6:

rpmbuild -ba ~/rpmbuild/SPECS/bareos.spec –define “centos_version 600”

And on CentOS 7:

rpmbuild -ba ~/rpmbuild/SPECS/bareos.spec –define “centos_version 700”

Once this finishes, you should find a collection of several Bareos RPMs in ~/rpmbuild/RPMS/x86_64/. We need the bareos-common package installed for build the Web UI, so become root and install it.

On CentOS 6:

yum -y install /home/build/rpmbuild/RPMS/x86_64/bareos-common-17.2.5-0.el6.x86_64.rpm

On CentOS 7:

yum -y install /home/build/rpmbuild/RPMS/x86_64/bareos-common-17.2.5-0.el7.centos.x86_64.rpm

Next, edit the ~/rpmbuild/SPECS/bareos-webui.spec file in your favourite text editor and set “Version” (line 4) to “17.2.5”.

Now you’d ready to build the Web UI package:

rpmbuild -ba ~/rpmbuild/SPECS/bareos-webui.spec

Finally, edit ~/rpmbuild/SPECS/python-bareos.spec in your favourite text editor and set “Version” (line 21) to “17.2.5” as well as “Release” (line 22) to “0%{?dist}” and build the final package:

rpmbuild -ba ~/rpmbuild/SPECS/python-bareos.spec

You should now have the full compliment of RPMs in ~/rpmbuild/RPMS/x86_64/ and ~/rpmbuild/RPMS/noarch/.

If you need to rebuild the RPMs for the same version of Bareos for any reason, then you should increment the value of Release in the relevant .spec file by 1 each time (e.g. “1%{?dist}”, “2%{?dist}” etc.).

You can now GPG sign your RPMs if you want and then add them to your own central yum repository with createrepo or just directly install them locally with rpm.
