Update the OS

Before starting the repository setup, it is a good idea to first update and upgrade the OS; run the following commands to update the OS and get some packages.

$ sudo yum update$ sudo yum install pygpgme yum-utils

Package Cloud Repository

Build artifacts are also posted to a packagecloud.io Repository. This includes official point releases. To use any of these build artifacts, create a file ‘/etc/yum.repos.d/fdio-release.repo’ with the content that points to the version needed. Below are some common examples of the content needed:

VPP Latest Release

To allow ‘yum’ access to the official VPP releases, create the file ‘/etc/yum.repos.d/fdio-release.repo’ with the following content.

$ cat /etc/yum.repos.d/fdio-release.repo[fdio_release]name=fdio_releasebaseurl=https://packagecloud.io/fdio/release/el/7/$basearchrepo_gpgcheck=1gpgcheck=0enabled=1gpgkey=https://packagecloud.io/fdio/release/gpgkeysslverify=1sslcacert=/etc/pki/tls/certs/ca-bundle.crtmetadata_expire=300​[fdio_release-source]name=fdio_release-sourcebaseurl=https://packagecloud.io/fdio/release/el/7/SRPMSrepo_gpgcheck=1gpgcheck=0enabled=1gpgkey=https://packagecloud.io/fdio/release/gpgkeysslverify=1sslcacert=/etc/pki/tls/certs/ca-bundle.crtmetadata_expire=300

Update your local yum cache.

$ sudo yum clean all$ sudo yum -q makecache -y --disablerepo='*' --enablerepo='fdio_release'

The ‘yum install vpp’ command will install the most recent release. To install older releases, run the following command to get the list of releases provided.

$ sudo yum --showduplicates list vpp* | expand

VPP Master Branch

To allow yum access to the nightly builds from the VPP master branch, create the file ‘/etc/yum.repos.d/fdio-release.repo’ with the following content.

$ cat /etc/yum.repos.d/fdio-release.repo[fdio_master]name=fdio_masterbaseurl=https://packagecloud.io/fdio/master/el/7/$basearchrepo_gpgcheck=1gpgcheck=0enabled=1gpgkey=https://packagecloud.io/fdio/master/gpgkeysslverify=1sslcacert=/etc/pki/tls/certs/ca-bundle.crtmetadata_expire=300​[fdio_master-source]name=fdio_master-sourcebaseurl=https://packagecloud.io/fdio/master/el/7/SRPMSrepo_gpgcheck=1gpgcheck=0enabled=1gpgkey=https://packagecloud.io/fdio/master/gpgkeysslverify=1sslcacert=/etc/pki/tls/certs/ca-bundle.crtmetadata_expire=300

Update your local yum cache.

$ sudo yum clean all$ sudo yum -q makecache -y --disablerepo='*' --enablerepo='fdio_master'

The ‘yum install vpp’ command will install the most recent build on the branch. Run the following command to get the list of images produce by the branch.

$ sudo yum clean all$ sudo yum --showduplicates list vpp* | expand

Install VPP RPMs

To install the VPP packet engine, run the following command:

$ sudo yum install vpp

The vpp RPM depends on the vpp-lib and vpp-selinux-policy RPMs, so they will be installed as well.

Note

The vpp-selinux-policy will not enable SELinux on the system. It will install a Custom VPP SELinux policy that will be used if SELinux is enabled at any time.

There are additional packages that are optional. These packages can be combined with the command above and installed all at once, or installed as needed:

$ sudo yum install vpp-plugins vpp-devel vpp-api-python vpp-api-lua vpp-api-java vpp-debuginfo vpp-devel libvpp0

Starting VPP

Once VPP is installed on the system, to run VPP as a systemd service on CentOS, run the following command:

$ sudo systemctl start vpp

Then to enable VPP to start on system reboot, run the following command:

$ sudo systemctl enable vpp

Outside of running VPP as a systemd service, VPP can be started manually or made to run within GDB for debugging. See Running VPP for more details and ways to tailor VPP to a specific system.

Uninstall the VPP RPMs

To uninstall a VPP RPM, run the following command:

$ sudo yum autoremove vpp*
