Next instructions are taken from CentOS wiki:
Download the rpmforge-release package. Choose one of the two links below, selecting to match your host's architecture. If you are unsure of which one to use you can check your architecture with the command uname -i
The preferred rpmforge-release package to retrieve and to install in order to enable that repository is one of the two listed above.
Install DAG's GPG key
rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt
Verify the package you have downloaded
rpm -K rpmforge-release-0.5.2-2.el5.rf.*.rpm
.
Install the package
rpm -i rpmforge-release-0.5.2-2.el5.rf.*.rpm
This will add a yum repository config file and import the appropriate GPG keys.
Then try to install git with:
yum install git
Read the tutorial at CentOS wiki for more details:
Next is only the list of the commands to execute in order to setup the RPM build environment:
yum install rpm-build
yum install redhat-rpm-config
cd
mkdir -p ~/rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
echo '%_topdir %(echo $HOME)/rpmbuild' > ~/.rpmmacros
cd mkdir kamailio 3.1 cd kamailio-3.1 git clone --depth 1 git://git.sip-router.org/sip-router kamailio cd kamailio git checkout -b 3.1 origin/3.1
Create the tarball from Kamailio sources:
make FLAVOUR=kamailio tar
cd mv kamailio-3.1/kamailio/kamailio-3.1.2_src.tar.gz rpmbuild/SOURCES/ cp kamailio-3.1/kamailio/pkg/kamailio/rpm/kamailio.init rpmbuild/SOURCES/ cp kamailio-3.1/kamailio/pkg/kamailio/rpm/kamailio.default rpmbuild/SOURCES/ cp kamailio-3.1/kamailio/pkg/kamailio/rpm/kamailio.spec.CentOS rpmbuild/SPECS/
yum install make yum install gcc yum install flex yum install bison yum install mysql-devel yum install openssl-devel yum install pcre-devel yum install postgresql-devel yum install unixODBC-devel yum install libxml2-devel yum install radiusclient-ng-devel yum install lm_sensors-devel yum install net-snmp-devel yum install curl-devel yum install expat-devel yum install libconfuse-devel yum install libpurple-devel yum install openldap-devel yum install mod_perl-devel yum install lua-devel yum install python-devel yum install yum install
cd ~/rpmbuild/SPECS rpmbuild -ba kamailio.spec.CenOS
When everything is finished, you will see next log messages printed in the terminal, which tell the location of RPMs:
