Install DB2 10.5 on Redhat Linux 6.5 for x86_64
近期发现在互联网上关于DB2 10.5的安装资料还是很少，如是打算发一篇关于DB2 10.5在Redhat Linux 6.5上安装的步骤，其实其安装和DB2以前的安装过程类似，简要的安装步骤如下，供参考。
1.安装配置环境
操作系统版本: Red Hat Enterprise Linux Server release 6.5 (Santiago) 数据库版本: DB2/LINUXX8664 10.5.3

[root@xuhz ~]# uname -a
Linux xuhz 2.6.32-431.el6.x86_64 #1 SMP Sun Nov 10 22:19:54 EST 2013 x86_64 x86_64 x86_64 GNU/Linux
[root@xuhz ~]# uname -r
2.6.32-431.el6.x86_64
[root@xuhz ~]# cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 6.5 (Santiago)

2.安装数据库软件
2.1 上传安装软件和license文件到某文件夹

[root@xuhz ~]# cd /software/
[root@xuhz software]# ls -l
total 1359328
drwxrwxrwx. 6 honcho honcho       4096 Jun  9 05:05 aese_c
-rwxrwxrwx. 1 honcho honcho 1391940725 Jun  9 05:05 DB2_Svr_10.5.0.3_Linux_x86-64PVU.tar.gz

2.2 解压缩安装包

[root@xuhz software]# gunzip DB2_Svr_10.5.0.3_Linux_x86-64PVU.tar.gz
[root@xuhz software]# tar -xvf DB2_Svr_10.5.0.3_Linux_x86-64PVU.tar

2.3 安装前预检测

[root@xuhz software]# ls -l
drwxrwxrwx. 6 honcho honcho       4096 Jun  9 05:05 aese_c
-rwxrwxrwx. 1 honcho honcho 1560576000 Jun  9 05:05 DB2_Svr_10.5.0.3_Linux_x86-64PVU.tar
drwxr-xr-x. 5 root   root         4096 Feb  7 08:33 server
[root@xuhz software]# cd server/
[root@xuhz server]# ls
db2  db2checkCOL_readme.txt  db2checkCOL.tar.gz  db2ckupgrade  db2_deinstall  db2_install  db2ls  db2prereqcheck  db2setup  ibm_im  installFixPack  nlpack
[root@xuhz server]# ./db2prereqcheck -v 10.5.0.3 -s -o /tmp/db_check.log
Requirement not matched for DB2 database "Server" . Version: "10.5.0.3". 
Summary of prerequisites that are not met on the current system:    DBT3514W  The db2prereqcheck utility failed to find the following 32-bit library file: "/lib/libpam.so*". 

DBT3514W  The db2prereqcheck utility failed to find the following 32-bit library file: "libstdc++.so.6". 


Requirement not matched for DB2 database "Server" with pureScale feature. Version: "10.5.0.3". 
Summary of prerequisites that are not met on the current system:    DBT3514W  The db2prereqcheck utility failed to find the following 32-bit library file: "/lib/libpam.so*". 

DBT3588W  The db2prereqcheck utility was unable to validate the configuration of the log_mtts_per_seg parameter on the following host machine: "xuhz". Reason code: "1". 

DBT3566E  The db2prereqcheck utility detected that the service named "rdma" is not enabled on host "xuhz". 

DBT3514W  The db2prereqcheck utility failed to find the following 32-bit library file: "libstdc++.so.6". 

DBT3563E  The db2prereqcheck utility determined that SELinux is enabled, which is not supported with GPFS.

上述报错IBM 给出了如下解释：

DBT3514W
The db2prereqcheck utility failed to find the following 32-bit library file: library-file-name.
Explanation
You can verify installation prerequisites for DB2 database using the db2prereqcheck utility.
This message is returned when the db2prereqcheck utility cannot find the 32-bit version of a required library file. If the named file is missing, 32-bit database applications might not function properly.
User response
Respond to this message in one of the following ways:
1> If you do not intend to use 32-bit applications with DB2 database, then no response is required.
2> If you do intend to use 32-bit applications with DB2 database, ensure that the named 32-bit library file exists on the system before installing DB2 database.

目前平台不打算使用32bit applications，故可以忽略以上警告信息。

2.4 采用命令行来安装数据库软件

[root@xuhz server]# ./db2_install 
Requirement not matched for DB2 database "Server" . Version: "10.5.0.3".

3.配置DB2 Instance
3.1 创建用户和组
用户用途 用户名 用户组
实例所有者 db2inst1 db2iadm1
受防护的用户 db2fenc1 db2fadm1
DB2 管理服务器用户 dasusr1 dasadm1
注：实例所有者主目录是将在其中创建DB2实例的位置；受防护的用户用于在DB2数据库所使用的地址空间之外运行用户定义的函数（UDF）和存储过程；DB2管理服务器用户的用户标识用于在系统上运行DB2管理服务器。

[root@xuhz ~]# groupadd  db2iadm1
[root@xuhz ~]# groupadd  db2fadm1
[root@xuhz ~]# groupadd  dasadm1
[root@xuhz ~]# useradd -u 600 -g db2iadm1 -m -d /home/db2inst1 db2inst1
[root@xuhz ~]# useradd -u 601 -g db2fadm1 -m -d /home/db2fenc1 db2fenc1
[root@xuhz ~]# useradd -u 602 -g dasadm1 -m -d /home/dasusr1 dasusr1
[root@xuhz ~]# passwd db2inst1
Changing password for user db2inst1.
New password: 
BAD PASSWORD: it is based on a dictionary word
Retype new password: 
passwd: all authentication tokens updated successfully.
[root@xuhz ~]# passwd db2fenc1
Changing password for user db2fenc1.
New password: 
BAD PASSWORD: it is based on a dictionary word
Retype new password: 
passwd: all authentication tokens updated successfully.
[root@xuhz ~]# passwd dasusr1
Changing password for user dasusr1.
New password: 
BAD PASSWORD: it is based on a dictionary word
Retype new password: 
passwd: all authentication tokens updated successfully.

3.2 创建DAS

[root@xuhz ~]# cd /opt/ibm/db2/V10.5/instance/
[root@xuhz instance]# ./dascrt -u dasusr1
DBI1070I  Program dascrt completed successfully.

注：版本9.7中已经不推荐使用“DB2 管理服务器（DAS）”，在以后的发行版中可能会将其除去。DAS在DB2 pureScale环境中不受支持。
3.3 创建DB2 Instance

[root@xuhz instance]# ./db2icrt -u db2fenc1 db2inst1
DBI1446I  The db2icrt command is running.


DB2 installation is being initialized.

 Total number of tasks to be performed: 4 
Total estimated time for all tasks to be performed: 309 second(s)
.......................................................................................................
.......................................................................................................
Task #4 start
Description: Updating global profile registry 
Estimated time 3 second(s) 
Task #4 end 

The execution completed successfully.

For more information see the DB2 installation log at "/tmp/db2icrt.log.8120".
Required: Review the following log file also for warnings or errors:
"/tmp/db2icrt_local.log.*"
DBI1070I  Program db2icrt completed successfully.
[db2inst1@xuhz ~]$ db2ilist
db2inst1

4.配置DB2服务器的TCP/IP通信
4.1 设置DB2服务器的通信协议

[root@xuhz ~]# su - db2inst1
[db2inst1@xuhz ~]$ db2set -all
[i] DB2AUTOSTART=NO
[g] DB2SYSTEM=xuhz
[g] DB2INSTDEF=db2inst1
[g] DB2ADMINSERVER=dasusr1
[db2inst1@xuhz ~]$ db2set DB2COMM=tcpip
[db2inst1@xuhz ~]$ db2set -all
[i] DB2COMM=TCPIP
[i] DB2AUTOSTART=NO
[g] DB2SYSTEM=xuhz
[g] DB2INSTDEF=db2inst1
[g] DB2ADMINSERVER=dasusr1

4.2 更新服务器上services文件

[db2inst1@xuhz ~]$ cat /etc/services |grep DB2
ibm-db2         523/tcp                 # IBM-DB2
ibm-db2         523/udp                 # IBM-DB2
questdb2-lnchr  5677/tcp                # Quest Central DB2 Launchr
questdb2-lnchr  5677/udp                # Quest Central DB2 Launchr
DB2_db2inst1    60006/tcp              # DB2 连接服务端口
DB2_db2inst1_1  60007/tcp
DB2_db2inst1_2  60008/tcp
DB2_db2inst1_3  60009/tcp
DB2_db2inst1_4  60010/tcp
DB2_db2inst1_END        60011/tcp

4.3 更新服务器数据库管理文件

[db2inst1@xuhz ~]$ db2 get dbm cfg |grep SVCENAME
 TCP/IP Service name                          (SVCENAME) = 
 SSL service name                         (SSL_SVCENAME) = 
[db2inst1@xuhz ~]$ db2 update dbm cfg using SVCENAME 60006            
DB20000I  The UPDATE DATABASE MANAGER CONFIGURATION command completed 
successfully.
[db2inst1@xuhz ~]$ db2 get dbm cfg |grep SVCENAME
 TCP/IP Service name                          (SVCENAME) = 60006
 SSL service name                         (SSL_SVCENAME) =

4.4 验证通信端口状态

[db2inst1@xuhz ~]$ db2start
06/09/2014 19:38:44     0   0   SQL1063N  DB2START processing was successful.
SQL1063N  DB2START processing was successful.
[db2inst1@xuhz ~]$ netstat -an |grep 60006
tcp        0      0 0.0.0.0:60006               0.0.0.0:*                   LISTEN

5. 创建数据库

[db2inst1@xuhz ~]$ db2 create db honcho using codeset UTF-8 territory CN pagesize 8192
DB20000I  The CREATE DATABASE command completed successfully.
[db2inst1@xuhz ~]$ db2 connect to honcho

   Database Connection Information

 Database server        = DB2/LINUXX8664 10.5.3
 SQL authorization ID   = DB2INST1
 Local database alias   = HONCHO

至此，DB2数据库软件安装和数据库实例及数据库创建完成，相比Oracle的安装而言DB2的安装步骤更加简单。

這裡寫地不錯，很詳細，我按著說明，一步一步全成功了，特轉載。注本人和文章有一點不同：本人ＬＩＮＵＸ是Redhat Linux 7.1

还有一点特别重要：

　　　　　上面4.3步骤设置有问题，导致客户端连接不了。ＤＢ2默认端口是50000，应该这样改：

 db2 update dbm cfg using SVCENAME　DB2_db2inst1_1，这里的“DB2_db2inst1_1”要与/etc/services以下内容一致，否则连不上：

DB2_db2inst1 60000/tcp
DB2_db2inst1_1 50000/tcp
DB2_db2inst1_2 60002/tcp
DB2_db2inst1_3 60003/tcp
DB2_db2inst1_4 60004/tcp
DB2_db2inst1_END 60005/tcp
