    系统镜像启动完成之后登录账号:rancher  密码:rancher
    安装图解:
    
    
    系统镜像启动完成
    
    登录用户名密码都是rancher
    添加IP地址:
    sudo ip addr add 192.168.21.133/24 dev eth0
    或者
    sudo ifconfig eth0 192.168.21.133 netmask 255.255.255.0
    添加网关:
    sudo route add default gw 192.168.21.2
    修改DNS:

    nameserver 8.8.8.8
    nameserver 8.8.4.4
    :wq! #保存退出
    使用ssh客户端远程连接服务器
    配置ssh远程秘钥登录,把rancheros安装到硬盘之后,必须使用秘钥登录,否则无法操作服务器,在控制台也无法使用密码登录。
    ssh-keygen -t rsa #配置秘钥登录
    将生成的公钥id_rsa.pub写到cloud-config.yml文件中
    
    cd /home/rancher/.ssh/
    cat id_rsa.pub #公钥
    ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQD1T22ANdfXPKWM1o8Crgnjy9yEjBj7SCKmSvsPcVLITGTkEIbInh61wpYo51TPyHJjPtEBfjeXZ7D8wQpGQPcNpFydwSK9Nec7jedSRHIEOQKGuayK12D61FhKQSXopt9PsFaZ7efzlFvo/HAlCMJqM1O4IHbeDfdF9iR/lVirku087JApvZyfpGn9a2v6Je11psG2AnZqvGggNFfTpszs1KsGtFrvy/c/iQEeayH0dj5bsL2lQw4me/YRLTSk9a0ApZknpSEoY51RWwT975coa9xTMy3C6rMhpiI14R/PNljVj/4h/T5g0B2shjeCcZEAwq0NKuOvlqmApMEqv0/n rancher@rancher

    把rancheros安装到硬盘
    sudo ros install -c cloud-config.yml -d /dev/sda #输入y安装,如果有错误,是因为网络原因,多试几次。
    
    
    直到安装完成,系统提示重新启动。
    把安装镜像去掉,让系统从硬盘启动。
    /dev/sda 是本地磁盘
    可以用命令查看
    sudo fdisk -l
