安装
node01作为主要的host，先安装cephadm
三个节点都要安装的包
安装docker，由于centos8默认安装了podman，安装docker会覆盖podman
dnf config-manager --add-repo=https://download.docker.com/linux/centos/docker-ce.repo dnf makecache dnf install docker-ce -y--allowerasingmkdir /etc/docker cat > /etc/docker/daemon.json << EOF { "registry-mirrors" : [ "http://ovfftd6p.mirror.aliyuncs.com", "http://registry.docker-cn.com", "http://docker.mirrors.ustc.edu.cn", "http://hub-mirror.c.163.com" ], "insecure-registries" : [ "registry.docker-cn.com", "docker.mirrors.ustc.edu.cn" ], "debug" : true, "experimental" : true} EOF
node01初始化
安装依赖
dnf install -y python3 vim net-tools telnet
