db2 v11在redhat7上安裝

1、設(shè)置主機名和修改/etc/hosts一致
hostnamectl --static set-hostname db2v11

2、安裝操作系統(tǒng)依賴包
yum  install  libstdc++.so.6

3、解壓包并安裝
./db2_deinstall
安裝目錄，選擇推薦目錄即可(可以修改目錄，如果不修改/預(yù)留大小為6G)
Enter "help" to redisplay product names. --------------- 選擇安裝產(chǎn)品類型，這里選擇SERVER
Do you want to install the DB2 pureScale Feature? [yes/no] ---------------- 選擇是否安裝pureScale功能，這里選擇不安裝

4、安裝完后初始化
groupadd db2iadm1                   
groupadd db2fadm1                                         
useradd db2inst1 -G db2iadm1          
useradd db2fenc1 -G db2fadm1       
cd /opt/ibm/db2/V11.1/instance/                   
./db2icrt -a server -p 50000 -u db2fenc1 db2inst1  

5、激活license                                       
以下操作全部以db2inst1用戶執(zhí)行查看license信息                                   
db2licm -l                                   
license激活                                   
db2licm -a /usr/local/src/db2ese_c.lic
   
6、修改實例

a、修改db2nodes.cfg（可選）位置在instance用戶的$HOME/sqllib/.文件格式是:
<logic port> <hostname> <logic port>   //主機名要與/etc/hosts 的主機名一致 或hostname命令查看

(2)  檢查services文件（多節(jié)點配置自動生成多個服務(wù)端口）
vi  /etc/services 
DB2c_db2inst1   50000/tcp  // 要與dbm SVCENAME一致
 
(3) 啟動實例： 
配置環(huán)境變量  --root用戶和db2inst1用戶
# vi ~/.bash_profile
$ vi ~/.bash_profile
./home/db2inst1/sqllib/db2profile  # 增加該行代碼
# source ~/.bash_profile
$ source ~/.bash_profile

設(shè)置服務(wù)名稱
$ db2 update dbm cfg using SVCENAME db2inst1
設(shè)置注冊變量
$ db2set DB2COMM=tcpip
啟動實例
$ db2start

7、創(chuàng)建數(shù)據(jù)庫
[root@localhost ~]# su - db2inst1
[db2inst1@localhost ~]$ cd /opt/ibm/db2/V9.7/bin
[db2inst1@localhost bin]$ ./db2sampl

8、調(diào)整數(shù)據(jù)庫參數(shù)
db2set DB2_PARALLEL_IO=*
db2set DB2_SKIPINSERTED=YES
db2set DB2_USE_ALTERNATE_PAGE_CLEANING=YES
db2set DB2_EVALUNCOMMITTED=YES
db2set DB2_ANTIJOIN=EXTEND
db2set DB2_SKIPDELETED=YES
db2set DB2CODEPAGE=1208

db2 update dbm cfg using DFT_MON_STMT   on

db2 update dbm cfg using DFT_MON_UOW   on

[db2inst1@db2v11 ~]$ db2 get dbm cfg |grep -i mon
 Transaction processor monitor name        (TP_MON_NAME) =
 Default database monitor switches
   Buffer pool                         (DFT_MON_BUFPOOL) = OFF
   Lock                                   (DFT_MON_LOCK) = OFF
   Sort                                   (DFT_MON_SORT) = OFF
   Statement                              (DFT_MON_STMT) = OFF
   Table                                 (DFT_MON_TABLE) = OFF
   Timestamp                         (DFT_MON_TIMESTAMP) = ON
   Unit of work                            (DFT_MON_UOW) = OFF
 Monitor health of instance and databases   (HEALTH_MON) = OFF
 SYSMON group name                        (SYSMON_GROUP) =
 Database monitor heap size (4KB)          (MON_HEAP_SZ) = AUTOMATIC(90)
 
授權(quán)
db2 get dbm cfg |grep -i sysmon
groupadd db2user
db2 update dbm cfg using SYSMON_GROUP db2user
db2 attach to db2inst1
db2 force applications all

db2 get dbm cfg |grep -i sysmon
useradd -g db2user  -d /home/dpmmon  -s /bin/bash -m  dpmmon
