PREFLIGHT CHECKLIST

The ceph-deploy tool operates out of a directory on an admin node. Any host with network connectivity and a modern python environment and ssh (such as Linux) should work.

CEPH-DEPLOY SETUP

register the target machine with subscription-manager, verify your subscriptions, and enable the “Extras” repository for package dependencies. For example:

yum install subscription-manager -y
sudo subscription-manager repos --enable=rhel-7-server-extras-rpms

Install and enable the Extra Packages for Enterprise Linux (EPEL) repository:

sudo yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Add the Ceph repository to your yum configuration file at /etc/yum.repos.d/ceph.repo with the following command. Replace {ceph-stable-release} with a stable Ceph release (e.g., luminous.) For example:

cat << EOM > /etc/yum.repos.d/ceph.repo
[ceph-noarch]
name=Ceph noarch packages
baseurl=https:

Operation

Copy file between two esxis

Check if SSH client service is enabled. Will return 'False' if 'Disabled'.

esxcli network firewall ruleset list --ruleset-id sshClient

Then enable SSH client.

esxcli network firewall ruleset set --ruleset-id sshClient --enabled=true

List disk

df -hl

copy file between esxi

scp -r workspace/ 192.168.0.111:/vmfs/volumes/datastore1

unregister vm

vim-cmd vmsvc/getallvms
vim-cmd vmsvc/unregister 13

INSTALLATION (MANUAL)

INSTALL PACKAGES WITH CEPHADM

prepare env

yum install python3 yum-utils -y
yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo
yum install docker-ce docker-ce-cli containerd.io
systemctl enable docker && service docker start
systemctl disable firewalld &&  service firewalld stop

Download the cephadm script

curl --silent --remote-name --location https://github.com/ceph/ceph/raw/pacific/src/cephadm/cephadm
chmod +x cephadm

Configure the Ceph repository based on the release name:

./cephadm add-repo --release Octopus
#https://docs.ceph.com/en/latest/releases/index.html

Install the appropriate packages. You can install them using your package management tool (e.g., APT, Yum) directly, or you can also use the cephadm wrapper. For example:

sudo rpm --import 'https://download.ceph.com/keys/release.asc'
./cephadm install
./cephadm install ceph-common

BOOTSTRAP A NEW CLUSTE

MicroK8s is the smallest, fastest, fully-conformant Kubernetes that tracks upstream releases and makes clustering trivial. MicroK8s is great for offline development, prototyping, and testing.

Install MicroK8s

Requirements

• Operating system which supports snapd
• At least 20G of disk space and 4G of memory are recommended
• An internet connection

For Centos7

service firewall stop && systemctl disable firewalld
yum install epel-release
yum install snapd
systemctl enable --now snapd.socket
sudo ln -s /var/lib/snapd/snap /snap

Install MicroK8s

MicroK8s will install a minimal, lightweight Kubernetes you can run and use on practically any machine. It can be installed with a snap:

snap install microk8s --classic --channel=1.21/stable
snap install microk8s --classic --channel=1.19/stable
#from 1.21 to 1.19
snap refresh --classic --channel=1.19/stable microk8s

All the currently available channels are shown if you run

snap info m

Install

Debian / Ubuntu:

apt-get install python-pip
pip install shadowsocks

CentOS:

yum install python-setuptools && easy_install pip
#curl -o get-pip.py https://bootstrap.pypa.io/pip/2.7/get-pip.py && python get-pip.py

Windows:

See [Install Server on Windows]

Usage

ssserver -p 443 -k password -m aes-256-cfb

To run in the background:

sudo ssserver -p 443 -k password -m aes-256-cfb --user nobody -d start
ssserver --log-file /var/log/shadowsocks-12300.log --pid-file /var/run/shadowsocks-12300.pid --user nobody -p 12300 -k password -m aes-256-cfb -s 0.0.0.0 -d start

To stop:

sudo ssserver -d stop

To check the log:

sudo less /var/log/shadowsocks.log

Check all the options via -h. You can also use a [Configuration] file
instead.

Install MongoDB Community Edition

MongoDB only supports the 64-bit versions of these platforms.

Follow these steps to install MongoDB Community Edition using the yum package manager.

Create a /etc/yum.repos.d/mongodb-org-4.4.repo file so that you can install MongoDB directly using yum:

[mongodb-org-4.4]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.4/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.4.asc

To install the latest stable version of MongoDB, issue the following command:

sudo yum install -y mongodb-org

Alternatively, to install a specific release of MongoDB, specify each component package individually and append the version number to the package name, as in the following example:

sudo yum install -y mongodb-org-4.4.11 mongodb-org-server-4.4.11 mongodb-org-shell-4.4.11 mongodb-org-mongos-4.4.11 mongodb-org-tools-4.4.11

You can specify

Krew

Make sure that git is installed.

Run this command to download and install krew:

(
  set -x; cd "$(mktemp -d)" &&
  OS="$(uname | tr '[:upper:]' '[:lower:]')" &&
  ARCH="$(uname -m | sed -e 's/x86_64/amd64/' -e 's/\(arm\)\(64\)\?.*/\1\2/' -e 's/aarch64$/arm64/')" &&
  KREW="krew-${OS}_${ARCH}" &&
  curl -fsSLO "https://github.com/kubernetes-sigs/krew/releases/latest/download/${KREW}.tar.gz" &&
  tar zxvf "${KREW}.tar.gz" &&
  ./"${KREW}" install krew
)

Add the $HOME/.krew/bin directory to your PATH environment variable. To do this, update your .bashrc or .zshrc file and append the following line:

export PATH="${KREW_ROOT:-$HOME/.krew}/bin:$PATH"

and restart your shell.

Run kubectl krew to check the installation.

kubectx + kubens

export HTTP_PROXY=http://192.168.0.201:6666
export HTTPS_PROXY=http://192.168.0.201:6666
kubectl krew install ctx
kubectl krew install ns
