I tried for the first time to install Ansys on a CentOS8 server. Currently I have the problem that I can not connect to a client (Windows) using the RSM Configuration 2021 R2.

Short key data about the system:

   - The server is a HPC GPU cluster (CentOS8) - it is only one Server so everything except the license server should run on this server.

   - There is an esternen license server

   - Users of the cluster all have Windows laptops

Here is a step by step guide I did on the CentOS8 server. No errors were thrown during installation or configuration. Since this is the first time I am running this, I may have missed something.

# 1.Step: Mount iso files to directories (see pdf: ANSYS_INC._Installation_Guides.pdf)

mount -ro loop /home/ISO/ANSYS2021R2_LINX64_Disk1.iso /mnt/iso/1/
mount -ro loop /home/ISO/ANSYS2021R2_LINX64_Disk1.iso /mnt/iso/2/
mount -ro loop /home/ISO/ANSYS2021R2_LINX64_Disk1.iso /mnt/iso/3/

# Step 2: Install in silent mode

INSTALL -silent -media_dir2 /mnt/iso/2/ -media_dir3 /mnt/iso/3/

# Step 3:

/usr/ansys_inc/v212/ProductConfig.sh -silent

# 4.Step: Open file and add configuration (add lines)

nano /etc/bashrc
export PATH=$PATH:/usr/ansys_inc/v212/ansys/bin
export PATH=$PATH:/usr/ansys_inc/shared_files/licensing/lic_admin

# 5.Step: Configuring the server information (create file and add lines)

touch /usr/ansys_inc/shared_files/licensing/ansyslmd.ini
nano /usr/ansys_inc/shared_files/licensing/ansyslmd.ini

# 6.Step: Install that RSM Launcher Service starts at Boot Time and check installation (see pdf: Remote_Solve_Manager_Tutorials_2021_R2.pdf, page:123)

cd /usr/ansys_inc/v212/RSM/Config/tools/linux
./rsmconfig -launcher
Test: ps aux | grep Ans.Rsm

# 7. Step: Launching the RSM Configuration Application (ANSYS_Remote_Solce_Manager_Users_Guide.pdf, page:33)

/usr/ansys_inc/v212/RSM/Config/tools/linux/rsmclusterconfig

# 8. Step: Ensure that the variable is passed correctly when installing these services

sudo -E /usr/ansys_inc/v212/RSM/Config/tools/linux/install_daemon -launcher
sudo -E /usr/ansys_inc/v212/RSM/ARC/tools/linx64/install_daemon -arcmaster -arcnode
/usr/ansys_inc/v212//RSM/Config/tools/linux/rsmlauncher restart

Configuration of the RSM Configuration 2021 R2:

HPC-Ressource:

• Name: New HPC-Konfiguration
• HPC-Type: LSF
• Submit-Host: CLUSTER_ADDRESS

File Management:

• RSM internal file transfer mechanism
• Staging directory path on cluster: \CLUSTER_ADDRESSstaging
• HPC Side File Management: HPC staging directory

I would appreciate help especially regarding the installation, configuration and queues.

I am assuming you are submitting from a windows computer to this Linux computer. please double check if the RSM needs to be configured for multiple NICs as per RSM trouble shooting guide. Please also see if you need to set userproxy port range per the documentation and open those ports in the firewall

Thank you for your reply.
First, yes your guess is correct. The requests are going from a Windows laptop to a Linux server.
The server does not have multiple NICs so they are not configured.
In which manual do I find the configuration of the userproxy port range?

I have now tried to connect to the server via my Windows laptop. For this I used the RSM Configuration. When I go to the last tab "Queues" and run a test, I get the following message:
"Access data could not be validated:
System.Runtime.Remoting.RemotingException: the remote service LauncherService at xxxx:9212 could not be reached."
I saw in another forum post that it is mostly a firewall issue. However, the server does not currently have a firewall. But beyond that the service is running fine, when I type "sudo netstat -lntup" I also see the active service on port 9212 (see image). And likewise I can ping the server.

I have changed the settings in the meantime:

Configuration of the RSM Configuration 2021 R2:
HPC-Ressource:
Name: New HPC-Konfiguration
HPC-Type: ARC
Submit-Host: CLUSTER_ADDRESS
File Management:
RSM internal file transfer mechanism
Staging directory path on cluster: \\CLUSTER_ADDRESS\staging
HPC Side File Management: HPC staging directory

Please search RSM documentation for your version for 9192 not reached
Steps to address it are listed in the Firewall section of the trouble shooting guide
