linux 安裝ps需要先安裝的rpm包

安裝db2 10.5需要下面的包：
yum -y install libstdc*i686 pam*i686 gcc* kernel-devel sg3_utils* sg_persist* 

安裝9.5需要下面的包：
 yum -y install compat-libstdc*i686

在檢查過程中發現：


*********************************************************************************
[root@onekey server]# ./db2prereqcheck           
WARNING:
   The 32 bit library file libstdc++.so.5 is not found on the system. 
   32-bit applications may be affected.  
WARNING:
DBT3534W  The db2prereqcheck utility determined that ASLR is set to ON and that this could cause issues with some tools.

解決方法：

以下列其中一種方式來響應本錯誤：

• 透過設定以下核心引數來關閉隨機化：

  kernel.randomize_va_space=0

• 透過發出以下命令來臨時禁用隨機化並重新啟動 DB2 例項：

  echo 0 > /proc/sys/kernel/randomize_va_space

[root@onekey server_t]# ./db2prereqcheck -v 10.5.0.8
