安装相关包

要配置 NIM Server，首先需要安装必需的 filesets，安装以下几个包：

bos.sysmgt.nim.master
bos.sysmgt.nim.client
bos.sysmgt.nim.spot

我们可以从系统光盘 DVD 1 中来安装这几个包。首先在空间足够大的文件系统中创建目录，来作为挂载点，然后创建 loopback 的 device，通过 loopback device 将 DVD 1 挂载到创建好的目录之下：

bash:/ # mkdir /opt/iso
bash:/ # mkdev -c loopback -s node -t loopback
loop2 Available
bash:/ # loopmount -i /opt/AIX_7.1_Base_Operating_System_TL_7100-03-00_DVD_1_of_2_112013.iso -l loop2 -o "-V cdrfs -o ro" -m /opt/iso 
bash:/ #

挂载好之后通过 installp 命令来安装相关的包：

bash:/ # installp -acgXd /opt/iso bos.sysmgt.nim

bos.sysmgt.nim.master 7.1.3.0 USR APPLY SUCCESS

以上省略了一些输出信息，可以看到 client 包已经安装了，另外为我们安装了 spot 和 master 包。

初始化 NIM Server

相关 filesets 安装好之后，通过 smitty nim 菜单来初始化 NIM Server。

bash:/ # smitty nim
=> Configure the NIM environment => Advanced configuration => Initialize the NIM master only

Configure Network Installation Management Master Fileset

Type or select values in entry fields.
Press Enter AFTER making all desired changes.
 
 [Entry Fields]
* Network Name [master_net]
* Primary Network Install Interface [en0] +
 
 Allow Machines to Register Themselves as Clients? [yes] +
 Alternate Port Numbers for Network Communications
 (reserved values will be used if left blank)
 Client Registration [] #
 Client Communications [] #
 IP Protocol Version Preference [] +#









F1=Help F2=Refresh F3=Cancel F4=List
F5=Reset F6=Command F7=Edit F8=Image
F9=Shell F10=Exit Enter=Do

上面的 Network Name 填写任意容易识别的名称，而 Primary Network Install Interface 填写公网网卡即可。可以通过 lsnim -l master 命令来确认 NIM Master 已经正常工作。

bash:/ # lsnim -l master
master:
 class = machines
 type = master
 max_nimesis_threads = 20
 if_defined = chrp.64.ent
 comments = machine which controls the NIM environment
 platform = chrp
 netboot_kernel = 64
 if1 = master_net_v6 fe80::ecc6:77ff:fe25:6402 fe80::ecc6:77ff:fe25:6402
 if2 = master_net_v4 aix116099.cdc.veritas.com EEC677256402
 cable_type1 = N/A
 cable_type2 = N/A
 Cstate = ready for a NIM operation
 prev_state = information is missing from this object's definition
 Mstate = currently running
 serves = boot
 serves = nim_script
 master_port = 1058
 registration_port = 1059
 reserved = yes

配置 LPP_SOURCE

现在来配置 LPP_SOURCE，首先创建文件系统来存放相关文件，这里我们从 rootvg 上创建一个 5G 的文件系统，路径为 /opt/nim/lpp_source。

bash:/ # crfs -v jfs2 -g rootvg -m /opt/nim/lpp_source -a size=5G
File system created successfully.
5242516 kilobytes total disk space.
New File System size is 10485760
bash:/ #

通过 smitty nim 菜单来创建 LPP_SOURCE：

bash:/ # smitty nim
=> Perform NIM Administration Tasks => Manage Resources => Define a Resource => lpp_source

Define a Resource

Type or select values in entry fields.
Press Enter AFTER making all desired changes.
 
 [Entry Fields]
* Resource Name [7103_lpp] 
* Resource Type lpp_source
* Server of Resource [master] +
* Location of Resource [/opt/nim/lpp_source/7103] /
 NFS Client Security Method [] +
 NFS Version Access [] +
 Architecture of Resource [] +
 Source of Install Images [/opt/iso] +/
 Names of Option Packages [all]
 Show Progress [yes] +
 Comments [7103 lpp_source]
 
 
 
 
 
 
 
F1=Help F2=Refresh F3=Cancel F4=List
F5=Reset F6=Command F7=Edit F8=Image
F9=Shell F10=Exit Enter=Do

上面的 Resource Name 填写容易识别的名字，Server of  Resource 填写 master，Location of Resource 填写上一步专门为 LPP_SOURCE 创建的文件系统下面的路径，Source of Install Images 填写 DVD 1 的挂载路劲， Names of Option Packages 填写 all，表示所有的包，Comments 可以填写任意容易识别的名称。点击 Enter，一段时间后 LPP_SOURCE 就创建好了，这取决于包的多少和机器的性能。

也可以不使用 smitty，而使用命令行的方式来创建 LPP_SOURCE:

bash:/ # nim -o define -t lpp_source -a location=/opt/nim/lpp_source/7103 -a server=master -a comments='7103 lpp_source' -a multi_volume=yes -a source=/opt/iso -a packages=all 7103_lpp

LPP_SOURCE 创建好后，通过 lsnim 命令来验证：

bash:/ # lsnim -l 7103_lpp
7103_lpp:
 class = resources
 type = lpp_source
 comments = 7103 lpp_source
 arch = power
 Rstate = ready for use
 prev_state = unavailable for use
 location = /opt/nim/lpp_source/7103
 simages = yes
 alloc_count = 0
 server = master

配置 NIM Client

在 Client 机器上，首先确保 bos.sysmgt.nim.client 包已经安装，如果没有安装，通过 installp 命令从 DVD 1 安装。

然后通过 smitty nim 菜单来配置 NIM Client：

bash:/ # smitty nim
=> Configure Network Installation Management Client Fileset

 Configure Network Installation Management Client Fileset

Type or select values in entry fields.
Press Enter AFTER making all desired changes.
 
[TOP] [Entry Fields]
* Machine Name [client_name]
* Primary Network Install Interface [en0] +
* Host Name of Network Install Master [nim_server_ip]
 
 Hardware Platform Type chrp
 Kernel to use for Network Boot [64] +
 Communication Protocol used by client [] +
 Ethernet Interface Options
 Network Speed Setting [] +
 Network Duplex Setting [] +
 VLAN Tag Priority (0 to 7) [] #
 VLAN Tag Identifier (0 to 4094) [] #

F1=Help F2=Refresh F3=Cancel F4=List
F5=Reset F6=Command F7=Edit F8=Image
F9=Shell F10=Exit Enter=Do

上面 Machine Name 填写容易识别的名称，Primary Network Install Interface 填写公网网卡即可，Host Name of Network Install Master 填写前面所配置的 NIM Server 的 IP 地址。点击 Enter即可。可以看到 /etc 目录下生成了 niminfo 文件：

bash:/ # cat /etc/niminfo
#------------------ Network Install Manager ---------------
# warning - this file contains NIM configuration information
# and should only be updated by NIM
export NIM_NAME=client_name
export NIM_HOSTNAME=client_host_name
export NIM_CONFIGURATION=standalone
export NIM_MASTER_HOSTNAME=nim_server_host_name
export NIM_MASTER_PORT=1058
export NIM_REGISTRATION_PORT=1059
export NIM_SHELL="shell"
export NIM_MASTERID=00C22A854C00
export NIM_BOS_IMAGE=/SPOT/usr/sys/inst.images/installp/ppc/bos
export NIM_BOS_FORMAT=rte

配置好 NIM Client 后我们就可以通过 NIM Server 在 Client 上安装我们需要的包了。
