先決條件

已完成 Debian 安裝後步驟

• 安裝叢集需要時間同步 所以安裝 Chrony
• 部署套件會使用 SSH 所以安裝 sshd
• 部署時SSH

安裝 Podman

用 cephadm 部署會在容器運行 我們選擇 Podman

echo 'deb http://deb.debian.org/debian buster-backports main' >> /etc/apt/sources.list
echo 'deb https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/Debian_10/ /' > /etc/apt/sources.list.d/devel:kubic:libcontainers:stable.list
curl -L https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/Debian_10/Release.key | apt-key add -
apt-get update
apt-get -y -t buster-backports install libseccomp2
apt-get -y install podman

安裝套件

curl --silent --remote-name --location https://github.com/ceph/ceph/raw/octopus/src/cephadm/cephadm
chmod +x cephadm
wget -q -O- 'https://download.ceph.com/keys/release.asc' | apt-key add -
echo deb https://download.ceph.com/debian-octopus/ $(lsb_release -sc) main | tee /etc/apt/sources.list.d/ceph.list
apt-get update
./cephadm install cephadm ceph-common
mkdir -p /etc/ceph

Bootstrap

編輯 /etc/ceph/cephx.conf

[osd]
osd client watch timeout = 15
