Installing the Server on CentOS 7¶
Follow the steps below to install Scyld Cloud Workstation, replace the default SSL key and certificate files, and install the license file. After a service restart, you should be able to sign in with standard OS credentials.
Use the
wget
command to install the Scyld Cloud Workstation YUM repository for CentOS 7.% sudo wget https://updates.penguincomputing.com/scw/scw-el7.repo -P /etc/yum.repos.d
Use the
yum install
command to installscyld-cloud-workstation
.% sudo yum install -y ./scyld-cloud-workstation-11.3.0-1.el7.x86_64.rpm
The installer does the following:
Installs Scyld Cloud Workstation files to
/opt/scyld-cloud-workstation
Installs scyld-cloud-workstation.service to
/lib/systemd/system/
Reloads the systemd manager configuration using
systemctl daemon-reload
Enables the unit file with
systemctl enable scyld-cloud-workstation.service
If your server’s domain has a trusted SSL certificate, open the configuration file (
/opt/scyld-cloud-workstation/bin/scyld-cloud-workstation.xml
) and set the value ofopenssl.server.privateKeyFile
andopenssl.server.certificateFile
to its path. Using a trusted SSL certificate is recommended for maximum security.Install the license.
If you have a trial license (
scyld-cloud-workstation.lic
), copy it into/opt/scyld-cloud-workstation/bin
.If you have a floating license (
scyld-flexlm.lic
), proceed to Flexera License Management for instructions on installing Scyld FlexLM.
Verify that your firewall rules allow traffic over HTTPS (port 443).
ONLY IF you have a
scw-usb
feature in your license file: use theyum
command to installkmod-usbip
andusbip-utils
. These packages are needed to enable USB forwarding.% sudo yum install -y kmod-usbip usbip-utils
Use the
systemctl restart
command to restart the service:% sudo systemctl restart scyld-cloud-workstation.service
