DB2有免費試用版本和商業版本，不同版本都可以在官網進行下載，也可以進行商業版本的購買，本人所在的公司是在13年購買的一套db2 V9.7，大概40萬，總共就2套光盤，一套10幾張，裏邊有針對不同機型不同操作系統的db2 v9.7，據領導說序列號是存在單獨的一張光盤上的，那張光盤應該是最值錢的，其他的都可以官網上下載。後來我去找序列號那張光盤，硬是沒找到。只好問領導要之前拷出來的db2ese_c.lic文件。也可通過 #find / -name db2*.lic 查看當前機器上是否有序列號文件。
下邊就簡單介紹我的安裝過程：
本次安裝的服務器是從騰訊雲上申請的，操作系統爲Red Hat 4.8.5-11，安裝文件是從光盤裏拷出來的DB2_ESE_9_7_0_0_LNXX86_64.iso，也可以將光盤掛載進行安裝，序列文件是從領導電腦拷過來的db2ese_c.lic，貌似序列號可以用很多次，不知道IBM是如何限制的。
1，將安裝文件DB2_ESE_9_7_0_0_LNXX86_64.iso拷貝到服務器/ opt下
2，將安裝文件掛載到的/ mnt目錄下
3，進入到/ mnt目錄執行安裝命令./db2_install
4，輸入“yes”進行軟件安裝目錄更改，輸入“no”則默認安裝路徑
5，輸入“ESE”選擇企業商用版本
6，註冊license（將序列文件db 2ese_c.lic拷貝到服務器/ opt下，進入db2安裝路徑 /opt/ibm/db2/V9.7/adm下執行./db2licm -a /opt/db2ese_c.lic ）
7，db2安裝路徑/opt/ibm/db2/V9.7/adm下執行（./db2licm -l）查看註冊情況
8，添加用戶組，用戶（分別是擁有實例的用戶，受到防護的用戶，DAS用戶），爲用戶組設置密碼
9，創建實例
10，配置DB2（設置DB2自啓動（注：依然在root用戶下），修改端口，修改DB2連接方式爲TCP / IP）
11，實例用戶下創建數據庫
12，將數據庫權限賦給某用戶
13，創建用戶臨時表空間（在存儲過程中使用臨時表時需要）
14，創臨時表空間的權限賦予某個用戶
15，設置日誌主要參數，重啓數據庫
16，建表，查詢
17，測試完畢，刪除數據庫
18，停實例，切換root用戶，在DB2目錄安裝執行命令刪除實例釋放空間
19，db2安裝路徑/opt/ibm/db2/V9.7/install下執行#./db2_deinstall -a 命令卸載db2軟件
20，善後 刪除用戶和組,及主目錄
