需要的其它套件：

> NOTE：
> 
> \- *libstdc++ 需要 32bit 與 64bit 都安裝。*
> 
> *- 需要的 32bit 的套件都應該在原始安裝來源目錄內，如果找不到，可能少了 DVD2 的安裝來源。*

```
#> yum install pdksh nfs-utils rsh-server compat-libstdc++-296.i386 compat-libstdc++-33.i386 compat-libstdc++-33.x86_64 openssh
```

CentOS 系統調校：

```
關閉 SELinux
#> setenforce 0
#> sed -i 's/SELINUX=.*$/SELINUX=disabled/' /etc/selinux/config  

停用 NetworkManager
#> service NetworkManager stop
#> chkconfig NetworkManager off
```

##### 安裝開始

主程式安裝

```editable
tar xzf DB2_AESE_97_Linux_x86-64.tar.gz
cd aese/
./db2prereqcheck
./db2_install -f NOTSAMP
```

-f NOTSAMP : 不要安裝 SAMP (System Automation for Multiplatforms)，因為 CentOS 不支援這功能。

Solution: Reboot the host, alternatively, manually clean up the below processes and rerun the db2prechk command to verify that it returns 0.

```shell
lsof +D /opt/ibm/db2/V9.7
