Installing dux on Linux

Dux for Linux can be installed using the package managers yum or dnf.

Dux supports installation on both RHEL-based Linux distributions (such as Red Hat Linux, AlmaLinux, and CentOS) and Debian-based Linux distributions (such as Ubuntu).

Procedure

For RHEL-based systems

Step 1 (Optional): Remove the old dux repository

If you have installed the Beta version 2.0.0.3 or earlier, ensure to clean up before proceeding with the installation.

Remove dux.repo
sudo rm /etc/yum.repos.d/dux.repo
Clean the package manager cache
sudo yum clean all
OR
sudo dnf clean all

Step 2: Install dux

Option 1: Create the dux.repo and install using yum or dnf

cat << EOF | sudo tee /etc/yum.repos.d/dux.repo
[dux]
name=Omnissa CLI - dux
baseurl=https://packages.omnissa.com/ws1-tunnel/dux
enabled=1
gpgcheck=1
gpgkey=https://packages.omnissa.com/ws1-tunnel/dux-apt/gpg.key
EOF

If using yum:

sudo yum install -y dux

If using dnf:

sudo dnf install -y dux

Result

The following directory structures are created:

/opt/omnissa/dux/
/opt/omnissa/dux/images/
/opt/omnissa/dux/logs/
/opt/omnissa/dux/scripts
/opt/omnissa/dux/certs

Run the following commands to validate the folder creation.

cd /opt/omnissa/
ls -ltr

drwxr-xr-x. 4 root root 32 Feb 16 17:59 dux

cd dux/
ls -ltr

which dux

/usr/bin/dux

Option 2: Install dux using rpm package for Linux

Download the dux rpm as per the architecture of the host from where dux is executed (x86_64 for AMD/Intel or aarch64 for ARM/Apple M1).

For example, if OS is Linux and Arch is amd64, the rpm dux-4.0.0.123-1.x86_64.rpm must be downloaded.

Run the command wget <url to download> or download manually.
