内核级虚拟化kvm–linux最小化安装使用–安装时启动网络–KVM安装–centos安装鼠标

1.安装基本命令：
yum -y install bash-completion tab补全命令
yum install net-tools 安装ifconfig 命令，好使用些
yum install vim

set -o vi 调成vi模式
grep -E ‘(vmx|svm)’ /proc/cpuinfo
yum install -y qemu-kvm libvirt (qemu-kvm是KVM在用户空间的管理工具，libvirt是用来管理KVM虚拟机的)
yum install -y virt-install(安装虚拟机用)
systemctl enable libvirtd
systemctl start libvirtd

centos安装鼠标：yum install -y gpm
chkconfig gpm
reboot

2.gpm的配置

gpm的配置

使用以下命令配置
$ gpm -m /dev/input/mice

在虚拟机下直接使用USB的参数就行，再启动gpm服务
$ systemctl start gpm.service
$ systemctl enable gpm.service

在我的Arch下不知为什么systemctl enable之后并不能开机自动启动，于是我用root用户加了一句
# echo “systemctl start gpm.service” >> ~/.bashrc
这样每次用root用户启动的时候就会自动启动gpm了。安装完之后就应该看到屏幕的光标，移动他，按住左键选中一段文字，然后移动到想要粘贴的地方按右键就可以粘贴了。

qemu -img create -f raw /opt/CentOS-7-x86_64.raw 10G
virt - install --virt-type kvm --name CentOS-7-x86_64 --ram 1024
–cdrom=/root/CentOS-7.2-x86_64-DVD-1511.iso --disk path=/opt/CentOS-7-x86_64.raw
–network network=default --graphics vnc,listen=0.0.0.0 --noautoconsole
3.常用命令
shift+PgUp 向前翻看,一般翻13页左右。
shift+PgDown 向后翻看,
Command+A和Command+E 行首和行尾
ssh [email protected] 连接
查看当前文件夹：pwd

4.添加阿里云yum软件源：
#cat << EOF > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF

安装kubeadm, kubelet , kubectl
yum install -y kubelet kubeadm kubectl --disableexcludes=kubernetes
systemctl enable kubelet && systemctl start kubelet

5.使用kubeadm创建单个master集群
K8S_VERSION=v1.11.2
ETCD_VERSION=3.2.18
DASHBOARD_VERSION=v1.8.3
FLANNEL_VERSION=v0.10.0-amd64
DNS_VERSION=1.1.3
PAUSE_VERSION=3.1

docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/kube-proxy-amd64: $K8S_VERSION k8s.gcr.io/kube-proxy-amd64:$ K8S_VERSION

初始化k8s：
kubeadm init --kubernetes-version=1.11.2 --pod-network-cidr=10.244.0.0/16 --apiserver -advertise-address=192.168.0.11
