Solaris 10 Jumpstart 安装

本周因为两个Jumpstart的细节出错，浪费了两个下午的时间。

Jumpstart Feature指的是Solaris系统自动的基于网的系统安装进程；其特点是安装速度快，不需要人工过多干预，可同时安装多台服务器。

Jumpsart组成包括：
Boot Server (in the same subnet with Client)
Install Server with targeted Solaris Images
Jumpstart Config Server,其他/Jumpstart目录中包括rules和profiles

现以install server and client在同一网段为例，Boot Server/Install Server/Config Server都在同一台服务上(无NIS服务)。其中The boot server包含rarpd (in.rarpd), bootp (in.bootparamd), and tftp (in.tftpd) 进程 (X86包括rplboot进程),Install Server是一个支持NFS的服务器，也叫NFS服务器。

配置步骤：

1，把OS image Copy到Install Server (以Solaris 10为例--5张CD）
# cd /cdrom/cdrom0/s0/Solaris_2.10/Tools
#./setup_install_server /export/Solaris_2.10

2,创建一个Profile Server,并沿用example里的profile,rules,beging/finish scripts
#mkdir /jumpstart
#cp -r /export/Solaris_2.10/Misc/jumpstart_sample/* /jumpstart
#share -F nfs -o ro,anon=0 /jumpstart
#shareall
#cd /jumpstart
# ./check
Validating rules...
Validating profile any_machine...
The custom JumpStart configuration is ok.
#cat rules.ok
any - - any_machine -

3，添加Client
#vi /etc/hosts
10.0.0.1 sh-test-1
#cd /jumpstart/Solaris_2.10/Tools
#./add_install_client –e 0:3:ba:f:33:89 dfsf sh-test-1 sun4u
#more /etc/ethers---确认client已被成功加入

4,客户端安装
ok>boot net - install

一般在10个ARP/RARP包里，客户机会收到服务器，并且开始传输数据，然后按安装提示一步一步地完成。如果Solaris10，在选择Solaris Software的时候，只能选[X}Entire Distribution plus OEM support ....... 4779.00 MB,否则会出错，或是成无盘站。如下是客户机和服务器间的交互过程:

1, Client sends a RARP for its IP address.
2, The Boot Server responds via RARPD (in.rarpd) with the IP address in /etc/ethers.
3, The client sends a tftp request for a bootimage.
4, The server starts in.tftp from inetd and sends the small net kernel image
5, The client then sends out a bootp request.
6, The server responds with the clients entry from /etc/bootparams.
7, The client NFS mount it’s root partition from the install server.
8, The client then mounts the configuration server (/jumpstart) and runs “sysidtool”.
9, It then mounts the install image and runs Suninstall to begin the install process.
