smartos教程四:安装SmartOS

前言

Smartos是一个开源的Unix系列操作系统,从Solaris10分支出来,由Joyent公司开发。Smartos拥有非常强大而简便的虚拟化功能,非常适合用来做云计算。这篇文章我们就介绍一下怎么安装SmartOS。

制作启动盘

因为SmartsOS启动的时候会将整个操作系统读取到内存,启动完毕后不在从启动盘读取文件,因此我们可以使用U盘、SD卡等移动存储设备制作启动盘。

现在我以Linux下将SmartOS安装到U盘为例进行讲解,其他操作系统可以参考官方文档:https://wiki.smartos.org/display/DOC/Creating+a+SmartOS+Bootable+USB+Key

首先去官网下载想要安装的版本。

下载地址:https://wiki.smartos.org/display/DOC/Download+SmartOS

下载完毕后解压

cd /tmp
wget https://us-east.manta.joyent.com/Joyent_Dev/public/SmartOS/smartos-latest-USB.img.bz2
tar xvjpf smartos-latest-USB.img.bz2

将U盘插入,查找U盘的设备路径,我的U盘路径为/dev/sdb

$ sudo fdisk -l
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk identifier: 0x00000000

Device Boot Start End Blocks Id System
/dev/sdb1 1 243 1951866 c W95 FAT32 (LBA)

将镜像刷到U盘中

cd /tmp
sudo dd if=smartos-latest-USB.img of=/dev/sdb bs=1024

设置分区激活状态

$ sudo fdisk /dev/sdb

Command (m for help): p

安装与启动系统

将制作好的U盘插入物理机,并且让物理机通过U盘启动,从默认的GRUB选项就能进入安装界面了。

安装界面是命令行交互的界面,根据提示依次配置好主网卡、IP、网关、磁盘冗余级别、时间服务器、密码即可,没有什么复杂的配置。

配置完后需要重新启动,现在只能通过U盘来启动,依然从默认的GRUB选项进入,这时候操作系统会去检查写入磁盘的文件,发现已经安装了系统,就不会再次安装了,而是读取文件进行配置,然后进入系统。
