To Fix the Problem: Issue starting xCAT daemon on Rocky Linux 9 and Oracle Linux 9

Error: After installing xcat packages on el9, service getting failed !

[root@cn01 ~]# lsxcatd -a
Unable to open socket connection to xcatd daemon on localhost:3001.
Verify that the xcatd daemon is running and that your SSL setup is correct.
Connection failure: IO::Socket::INET: connect: Connection refused at /opt/xcat/lib/perl/xCAT/Client.pm line 248.

Solution:

Note: Don’t Install xCAT packages from repo, if installed then removed the xcat packages

yum remove xCAT

To Install xcat on rhel9

git clone the repo

git clone https://github.com/OpenHPC-AI/install-xCAT-rhel9.git
cd install-xCAT-rhel9
#The setup_xcat.sh script installs xCAT and resolves the OpenSSL and initscripts issues.
chmod +x setup_xcat.sh
./setup_xcat.sh

Osimage configuration (copycds) for rocky9.6

Get the discinfo of rocky9.6 iso

# Install or copy rocky9.6 iso in your /tmp dir
# mount the iso in to /tmp/iso/rocky9.6/
mount  /tmp/Rocky-9.6-x86_64-dvd.iso /tmp/iso/rocky9.6/

#get the disinfo
cat /tmp/iso/rocky9.6/.discinfo | head -n 1
# expample discinfo for rocky9.6 dvd iso is: 1748309243.9338255

Once you get the discinfo id add in /opt/xcat/lib/perl/xCAT/data/discinfo.pm file

#For rocky9.6 dvd iso 
bash setup_disc info.sh

[OR]

You can manually setup the xcat on el9

Step1: Download the go-xcat tool using wget:

# Install go-xcat support package to fix the problem
wget https://raw.githubusercontent.com/xcat2/xcat-core/master/xCAT-server/share/xcat/tools/go-xcat -O - >/tmp/go-xcat

(or)
cd /tmp
git clone  https://github.com/OpenHPC-AI/go-xcat-el9.git

# Change the permission to execute
chmod +x /tmp/go-xcat-el9/go-xcat

Step2: Run the go-xcat tool:

/tmp/go-xcat -x latest install -y

NOTE:

1. This will fail with the certificate issue but carry on with the below.
2. I had previous suggested running the command with the devel option but it works with the standard install anyway.

Step3.

# Setup Openssl patch
bash ssl_patch_setup.sh

Step4.

Source the profile to add xCAT Commands to your path:

source /etc/profile.d/xcat.sh

Step6. Reinitialise the xcat installation:

xcatconfig -i -c -s

Step7. Restart the xcatd service and Check the xCAT version:

restartxcatd

lsxcatd -a

Tips:

You need to install the initscripts RPM. el9 dropped sysinit for systemd
and xCAT is sysinit based.
You have to do this before trying to install xCAT because it will break your /etc/init.d symlink.
go-xcat will install initscripts for you.
