Try Steps

Replace the repository for speedup:

sed -e 's|^mirrorlist=|#mirrorlist=|g'     -e 's|^#baseurl=http://dl.rockylinux.org/$contentdir|baseurl=https://mirrors.ustc.edu.cn/rocky|g'     -i.bak     /etc/yum.repos.d/rocky-extras.repo     /etc/yum.repos.d/rocky.repo
yum makecache

Install docker:

dnf config-manager --add-repo=https://download.docker.com/linux/centos/docker-ce.repo
# replace all of the `download.docker.com` into `https://mirrors.ustc.edu.cn/docker-ce`
yum makecache
yum install -y docker-ce
systemctl enable docker
systemctl start docker

Pull rockylinux9 and prepare building environment via:

docker pull rockylinux:9
docker run -it -v /root/source:/source rockylinux:9 /bin/bash
sed -e 's|^mirrorlist=|#mirrorlist=|g'     -e 's|^#baseurl=http://dl.rockylinux.org/$contentdir|baseurl=https://mirrors.ustc.edu.cn/rocky|g'     -i.bak     /etc/yum.repos.d/rocky-extras.repo     /etc/yum.repos.d/rocky.repo

Enable perftools building, I think it failed because of the libebpf is too new comparing to 5.15.113 kernel. so changes to kerner’s tools/lib/bpf version’s libebpf-devel package for building.

WorkingTipsOniventoy

Create the server:

cd Downloads
mkdir iventory
cd iventory
tar xzvf ../iventoy-1.0.17-linux-free.tar.gz
cd iventoy-1.0.17
sudo ./iventoy.sh start

Select the DHCP server mode for external:

Create the linked iso:

➜  ~ ls /home/dash/Downloads/iventory/iventoy-1.0.17/iso 
➜  ~ ln -s /media/121/iso/Rocky-9.2-x86_64-dvd.iso /home/dash/Downloads/iventory/iventoy-1.0.17/iso/Rocky-9.2-x86_64-dvd.iso

Start the server:

Using external dhcp server may need other configuration.

# vim /etc/dhcpd.conf

OnMeshCommander

Steps:

# docker run -it ubuntu:latest /bin/bash
In docker instance:    
# cd /root
# mkdir meshcommander
# cd meshcommander
# npm install meshcommander 

Then commit this docker instance to docker image:

# docker commit awgowugowugouawo meshcommander:mine

Start the instance:

docker run -it -p 4080:3000 meshcommander:ctyun /bin/bash

Edit the node modules:

root@938cedc55cde:~/meshcommander# vim node_modules/meshcommander/webserver.js 
156         obj.app.listen(port, '0.0.0.0', function () { console.log("MeshCommander running on http://127.0.0.1:" + port + '.'); });
node node_modules/meshcommander/

Visit the https://ip:4080 you could reache the meshcommander webpage.
