1下載DB2數據庫軟件包
mkdir -p /opt/db2v11.1/ cd /opt/db2v11.1/ wget https://iwm.dhe.ibm.com/sdfdl/v2/regs2/db2pmopn/Express-C/DB2ExpressC11/Xa.2/Xb.aA_60_-i7xG42x7rZcj9irKm9qfC4e8JXlT1bnFk_tk/Xc.Express-C/DB2ExpressC11/v11.1_linuxx64_expc.tar.gz/Xd./Xf.LPr.D1vk/Xg.9927581/Xi.swg-db2expressc/XY.regsrvs/XZ.RNzclAYCV6lTKjleviVov4YXSbA/v11.1_linuxx64_expc.tar.gz
2解壓軟件包
[root@localhost db2v11.1]# tar xf v11.1_linuxx64_expc.tar.gz
3開始安裝軟件包
[root@localhost ~]# yum install -y compat-libstdc++-33 libaio.so.1 [root@localhost expc]# cd /opt/db2v11.1/expc [root@localhost expc]# ./db2_install Default directory for installation of products - /opt/ibm/db2/V10.5 *********************************************************** Install into default directory (/opt/ibm/db2/V10.5) ? [yes/no] 是否選擇默認目錄安裝，選擇yes ************************************************* The execution completed successfully. 安裝命令執行完成
4注冊license
[root@localhost expc]# cd /opt/ibm/db2/V11.1/adm/ [root@localhost adm]# chmod 775 * [root@localhost adm]# ./db2licm -a /opt/db2v11.1/expc/db2/license/db2expc_uw.lic
5創建用戶組
[root@localhost adm]# groupadd -g 901 db2iadm1 [root@localhost adm]# groupadd -g 902 db2fadm1 [root@localhost adm]# groupadd -g 903 db2dadm1
6創建用戶
(分別是擁有實例的用戶,受防護的用戶,DAS用戶)且指定對應的用戶組
[root@localhost adm]# useradd -g db2iadm1 -u 101 -d /home/db2inst1 -m db2inst1 [root@localhost adm]# useradd -g db2fadm1 -u 102 -d /home/db2fenc1 -m db2fenc1 [root@localhost adm]# useradd -g db2dadm1 -u 103 -d /home/db2dasusr1 -m db2dasusr1
參數說明: -u uid 使用者的ID值,必須為唯一的ID值,除非用-o選項可以不唯一,數字不可為負值,0~999傳統上是保留給系統帳號使用。 -d path 使用者目錄 -m 使用者目錄如不存在則自動建立 -s shell 使用者登入后使用shell名稱作為提示符,如果不寫系統會幫你指定預設的登入shell
7添加用戶的密碼
[root@localhost adm]# passwd db2inst1
[root@localhost adm]# passwd db2fenc1
[root@localhost adm]# passwd db2dasusr1
8檢查用戶組和用戶
[root@localhost adm]# more /etc/group | grep db2 db2iadm1:x:901: db2fadm1:x:902: db2dadm1:x:903: [root@localhost adm]# more /etc/passwd | grep db2 db2inst1:x:101:901::/home/db2inst1:/bin/bash db2fenc1:x:102:902::/home/db2fenc1:/bin/bash db2dasusr1:x:103:903::/home/db2dasusr1:/bin/bash
9創建實例
(1)綁定端口號
[root@localhost instance]# cd /opt/ibm/db2/V11.1/instance [root@localhost instance]# ./db2icrt -p 50000 -u db2fenc1 db2inst1
(2)創建樣本數據庫
[root@localhost instance]# su - db2inst1 [db2inst1@localhost ~]$ db2sampl [db2inst1@localhost ~]$ db2start [db2inst1@localhost ~]$ db2 “select * from staff” [root@localhost instance]# ./dascrt -u db2dasusr1 (創建DB2管理服務器) [root@localhost instance]# ./db2icrt -u db2fenc1 db2inst1 (創建DB2實例)
10配置DB2
(1)設置DB2自啟動
[root@localhost instance]# su - [root@localhost instance]# cd /opt/ibm/db2/V10.5/instance [root@localhost instance]# ./db2iauto -on db2inst1
(2)修改網絡服務端口
(注:在db2inst1用戶下) ，修改DB2的服務端口為50658,默認情況下端口是50000(單實例的話可以不修改)
[root@localhost expc]# su - db2inst1 [db2inst1@localhost ~]$ db2 update dbm cfg using SVCENAME 50658
(3)修改DB2連接方式為TCP/IP
[root@localhost expc]# su - db2inst1
[db2inst1@localhost ~]$ db2set DB2COMM=TCPIP
(4)修改字符集
[db2inst1@localhost ~]$ db2set db2codepage=1208（也就是utf-8）
數據庫db2 系統centos xhell 三個字符集要一致
11查看DB2許可證
[db2inst1@localhost ~]$ db2licm -l Product name: "DB2 Express-C" License type: "Unwarranted" Expiry date: "Permanent" Product identifier: "db2expc" Version information: "11.1" Max number of CPUs: "2" Max amount of memory (GB): "16" Max number of cores: "2" Enforcement policy: "Soft Stop"
12創建數據庫並設置字符集
[root@localhost expcD]# su - db2inst1 [root@localhost expc]# db2 create database arapmdb2 using codeset UTF-8 territory CN pagesize 32768
可能會等的時間長一點
13連接數據庫
[db2inst1@localhost ~]$ db2 connect to arapmdb2 user db2inst1 using db2inst1
14創建BUFFERPOOL
[db2inst1@localhost ~]$ db2 create BUFFERPOOL testBUFFER SIZE 1000 PAGESIZE 32K
15創建TestTB表
[db2inst1@localhost ~]$ db2 "create table TestTB(id integer not null generated always as identity(start with 1,increment by 1),name varchar(10))" 插入數據 [db2inst1@localhost ~]$ db2 "INSERT INTO TestTB(name) VALUES('test')"
