root@solaris:~# zfs rollback -r rpool/VARSHARE@2015-01-13

此時系統檔案會回復到snapshot快照當時的狀態

刪除snapshot

Oracle 支援 Intelligent Platform Management Interface (IPMI)，分為Serial connection串列埠，及
NetMgt網路管理埠；

Serial connection串列埠以CLI命令列管理界面登入：

System Configuration Tool

System Configuration Tool enables you to specify the following
configuration parameters for your newly-installed Oracle Solaris 11
system:
- network, time zone, user and root accounts, name services

System Configuration Tool produces an SMF profile file in
/system/volatile/scit_profile.xml.

How to navigate through this tool:
- Use the function keys listed at the bottom of each screen to move
from screen to screen and to perform other operations.
- Use the up/down arrow keys to change the selection or to move
between input fields.
- If your keyboard does not have function keys, or they do not
respond, press ESC; the legend at the bottom of the screen will
change to show the ESC keys for navigation and other functions.

Solaris 變更主機名稱

1 - 檢查目前的環境的屬性參數:

root@t3-2:~# svccfg -s system/identity:node listprop config
config application
config/enable_mapping boolean true
config/ignore_dhcp_hostname boolean false
config/loopback astring
config/nodename astring t3-2

root@t3-2:~#

目前主機名稱為t3-2

2 - 設定新的主機名稱

root@t3-2:~# svccfg -s system/identity:node setprop config/nodename="NIASc11"

root@t3-2:~# svccfg -s system/identity:node setprop config/loopback="NIASc11"
改設定主機名稱為NIASc11

3- 更新屬性參數:

root@t3-2:~# svccfg -s system/identity:node refresh
root@t3-2:~# Hostname: NIASc11

4 - 重新啟動服務:

root@t3-2:~# svcadm restart system/identity:node

5 - 確認變更完成:

root@t3-2:~# svccfg -s system/identity:node listprop config

config application

config/enable_mapping boolean true

config/ignore_dhcp_hostname boolean false

config/nodename astring NIASc11

config/loopback astring NIASc11

Solaris 11 DNS Client 設定

檢查現有的DNS Client 設定
root@s11:~# svccfg -s network/dns/client listprop config
config application
config/value_authorization astring solaris.smf.value.name-service.dns.client

更新 DNS Client 設定
root@s11:~# svccfg -s network/dns/client setprop config/nameserver = net_address: "(168.95.1.1 8.8.8.8)"

root@s11:~# svccfg -s network/dns/client setprop config/domain = astring: test.com.tw

root@s11:~# svccfg -s network/dns/client setprop config/search = astring: '("test.com.tw" "test1.com.tw")'

設定名稱解析順序
root@s11:~# svccfg -s name-service/switch setprop config/ipnodes = astring: '("files dns")'
root@s11:~# svccfg -s name-service/switch setprop config/host = astring: '("files dns")'

檢視DNS Client變更的設定
root@s11:~# svccfg -s network/dns/client listprop config
config application
config/value_authorization astring solaris.smf.value.name-service.dns.client
config/nameserver net_address 168.95.1.1 8.8.8.8
config/domain astring test.com.tw
config/search astring "test.com.tw" "test1.com.tw"
root@s11:~#

檢視nsswitch變更的設定
root@s11:~# svccfg -s name-service/switch listprop config
config application
config/default astring files
config/value_authorization astring solaris.smf.value.name-service.switch
config/printer astring "user files"
config/ipnodes astring "files dns"
config/host astring "files dns"

匯出DNS Client 設定組態
root@s11:~# svcadm enable dns/client

root@s11:~# more /etc/resolv.conf (此時檢視/etc/resolv.conf並不存在)
/etc/resolv.conf: No such file or directory

root@s11:~# nscfg export svc:/network/dns/client:default
root@s11:~# more /etc/resolv.conf (此時檢視/etc/resolv.conf已建立)

root@s11:~# nscfg import -f name-service/switch:default

root@s11:~# nscfg import -f dns/client:defaul

===================分隔線 =========================================
此設定reboot 設定會清除

I. DNS client setup

1. 設定network/dns/client SMF 服務

# svccfg -s network/dns/client

svc:/network/dns/client> setprop config/search = astring: ("test.com.tw""test1.com.tw")

svc:/network/dns/client> setprop config/nameserver = net_address: (168.95.1.1 8.8.8.8)

svc:/network/dns/client> exit

2. 開啟 DNS client 服務 (第一次使用需要設定)

#svcadm enable -r dns/client

3.重啟/更新 DNS client 服務 (當設定完成或是有任何更新時)

#svcadm refresh dns/client

#svcadm restart dns/client

4. 檢查設定完成後/etc/resolv.conf 是否有更新(出現紅字部份)

# more /etc/resolv.conf

# _AUTOGENERATED_FROM_SMF_V1_

# WARNING: THIS FILE GENERATED FROM SMF DATA.

# DO NOT EDIT THIS FILE. EDITS WILL BE LOST.

# See resolv.conf(4) for details.

search cht.com.tw cht1.com.tw

nameserver xx.xx.xx.xx

nameserver yy.yy.yy.yy

---

II. 設定Name service switch 使用 DNS

1. 設定 system/name-service/switch SMF 服務

# svccfg -s system/name-service/switch

svc:/system/name-service/switch> setprop config/host = astring: "files dns"

svc:/system/name-service/switch>end

2. .重啟/更新 name-service/switch 服務

#svcadm refresh name-service/switch

#svcadm restart name-service/switch

3. 檢查設定完成後/etc/nsswitch.conf檔，出現紅字部份的更新)

# more /etc/nsswitch.conf

# _AUTOGENERATED_FROM_SMF_V1_

# WARNING: THIS FILE GENERATED FROM SMF DATA.

# DO NOT EDIT THIS FILE. EDITS WILL BE LOST.

# See nsswitch.conf(4) for details.

passwd: files

group: files

hosts: files dns

ipnodes: files dns

最後nslookup試試看DNS是否解析
