) and the license server (Scyld FlexLM).
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
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/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).
Use the
systemctl restart
command to restart the service:% sudo systemctl restart scyld-cloud-workstation.service
OPTIONAL: To enable USB Forwarding features, see Installing Server-USB Module on CentOS 7.
Scyld Cloud Workstation should now be reachable over HTTPS at your server’s hostname or IP address. For advanced configuration options, please see Setup.
Installing Server-USB Module on CentOS 7¶
USB devices can be forwarded between native clients and remote servers that meet the following requirements:
The server’s license file must have a valid ‘scw-usb’ entitlement. If you do not see this entitlement in your license file, please contact Penguin Computing sales for more information.
The Server-USB module must be installed on the remote server.
The Client-USB module must be installed on the client side. See Installing Client-USB Module on the Client for more information on this step.
To install the Server-USB modules on the remote server:
Use the
yum
command to installscyld-cloud-workstation-server-usb-module
.% sudo yum install -y scyld-cloud-workstation-server-usb-module
Use the
systemctl restart
command to restart the service:% sudo systemctl restart scyld-cloud-workstation.service
Installing the Server on Rocky Linux¶
Follow the steps below to install Scyld Cloud Workstation, replace the default SSL key and certificate files, install the license file, and change your X server from XWayland to Xorg. 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 your version of Rocky Linux:% ## Rocky Linux 8 only % sudo wget https://updates.penguincomputing.com/scw/scw-el8.repo -P /etc/yum.repos.d % ## Rocky Linux 9 only % sudo wget https://updates.penguincomputing.com/scw/scw-el9.repo -P /etc/yum.repos.d
Use the
yum install
command to installscyld-cloud-workstation
.% sudo yum install -y scyld-cloud-workstation
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 you have a trusted SSL certificate for your server’s domain, open the configuration file (
/opt/scyld-cloud-workstation/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 are using XWayland as your X server (enabled by default in Rocky Linux), enable Xorg by following these steps:
Open editor to open:
/etc/gdm/custom.conf
Look for the lines below:
[daemon] # Uncoment the line below to force the login screen to use Xorg #WaylandEnable=false
Uncomment (remove the ‘#’) preceeding the ‘WaylandEnable’ variable.
Save the file and reboot the system. The service will start after the reboot.
Use the
systemctl restart
command to restart the service:% sudo systemctl restart scyld-cloud-workstation.service
