step by step install netbackup client 6.5 on aix

概述:
OS: AIX 6100-05-01-1016
NETBACKUP CLIENT: 6.5
本文描述,在AIX 6.1上安裝netbackup client,用於備份aix 作業系統中的部分資料目錄.
本文涉及的AIX 6.1作業系統上安裝了TCP_WRAPPER軟體,用於系統的安全加固,所以配置netbackup client時需要開部分許可權給netbackup server .

一. 複製netbackup client 6.5安裝目錄到aix系統中
本例中是將安裝檔案複製到/imp32/netbackup_client/目錄中.

xxdb_node1:/imp32/netbackup_client/#ls
IA64 NB_65_ICS_1.4.37.3_WIN32 X86 x64
Launch.bat NB_65_ICS_1.4.37.3_WINIA64 autorun.inf
NBClients NB_65_ICS_1.4.37.3_WINX64 install
xxdb_node1:/imp32/netbackup_client#chmod -R 755 *

[@more@]

二. 執行install程式,進行client軟體的安裝
xxdb_node1:/imp32/netbackup_client#./install

The following temporary file can be deleted after you verify the proper

An automatic startup script, /etc/rc.client.netbackup has been installed.
This will cause NetBackup client daemons to be automatically
restarted each time the server boots.

That file can be deleted after you are sure the install was successful.

三. 配置tcp_wrapper ,允許netbackup server透過bpcp等程式的訪問aix主機
本節主要針對aix系統中安裝了tcp_wrapper防護軟體的情況,如果aix系統沒有安裝tcp_wrapper,可以跳過此節

xxdb_node1:/imp32/netbackup_client#vi /etc/hosts.allow
##新增相關伺服器的訪問許可權
bpcd:51.123.12.149:allow
vnetd:51.123.12.149:allow
bpcd:51.123.12.143:allow
vnetd:51.123.12.143:allow

其中: 51.123.12.149 是netbackup server
51.123.12.143 是netbackup media server

編輯好/etc/hosts.allow 檔案後,透過下面的命令,重新整理一下inetd服務
xxdb_node1:/#refresh -s inetd
0513-095 The request for subsystem refresh was completed successfully.

四. 配置aix系統/etc/hosts檔案,增加netbackup相關伺服器的地址
yxdb_node1:/#more /etc/hosts
......
51.123.12.149 netbackup-svr
51.123.12.143 netbackup-mssvr

五. 配置netbackup相關伺服器上的hosts檔案,新增aix系統的地址
本例中netbackup有兩個伺服器,一個主控伺服器,一個是媒體管理伺服器.
需要編輯windows系統的hosts檔案,本例為:C:WINDOWSSYSTEM32DRIVERSETCHOSTS檔案
新增如下內容:
51.123.13.150 xxdb_node1

注意:這裡的主機名稱應該和作業系統的hostname完全相同,否則在備份和恢復的時候容易出現意想不到的錯誤.
可以事先在aix系統中,執行hostname命令,檢視主機名稱
xxdb_node1:/#hostname
xxdb_node1

六.配置netbackup client的配置檔案bp.conf,新增相關伺服器的資訊
xxdb_node1:/#more /usr/openv/netbackup/bp.conf
SERVER = netbackup-svr
CLIENT_NAME = xxdb_node1
MEDIA_SERVER = netbackup-mssvr

七.在aix系統中,重新啟動netbackup client程式.
在aix系統中安裝了netbackup client後,安裝程式在/etc/inittab 檔案的最後一行增加一下內容，用於在下次作業系統重新啟動時自動啟動netbackup client 程式。
xxdb_node1:/#more /etc/inittab
......
tty0:2:off:/usr/sbin/getty /dev/tty0
nbclient:2:wait:/etc/rc.client.netbackup start

安裝程式在安裝的最後，提示有啟動netbackup client的操作步驟，但實際上沒有成功，在netbackup server 無法識別到。
需要手工啟動netbackup client，啟動前先關閉一下,然後在啟動,如下:
xxdb_node1:/#/etc/rc.client.netbackup stop
xxdb_node1:/#/etc/rc.client.netbackup start

八.定義備份策略後,進行備份
登陸到netbackup server,進入netbackup 管理端,定義備份策略,使用手工啟動備份的方式測試一下是否可以正常備份.

筆者曾經因為沒有配置好/usr/openv/netbackup/bp.conf檔案(忘了配置netbackup media server),導致備份的時候報下面的錯誤:
bpcd on xxxx_node1 exited with status 59: access to client was not allow

舊的bp.conf檔案內容:
xxdb_node1:/#more /usr/openv/netbackup/bp.conf
SERVER = netbackup
CLIENT_NAME = xxdb_node1

新增了media server的配置資訊,新的bp.conf檔案內容如下:
xxdb_node1:/#more /usr/openv/netbackup/bp.conf
SERVER = netbackup
CLIENT_NAME = xxdb_node1
MEDIA_SERVER = netbackup-ms

然後進行手工啟動備份,備份任務開始正常執行.
