NOTE: libstdc++ 需要 32bit 與 64bit 都安裝。

# yum install libstdc++.i686 pam-devel pam-devel.i686 ksh rsh-server

# rpm -qa | grep "ksh\|openssh\|rsh-server\|nfs-utils\|libaio\|libstdc++\|libstdc++.i686\|pam-devel\|pam-devel.i686"
libstdc++-4.4.7-16.el6.x86_64
nfs-utils-lib-1.1.5-11.el6.x86_64
openssh-clients-5.3p1-111.el6.x86_64
pam-devel-1.1.1-20.el6.i686
libaio-0.3.107-10.el6.x86_64
ksh-20120801-28.el6.x86_64
libstdc++-4.4.7-16.el6.i686

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

調整系統核心參數

#> ipcs -l

max seg size (kbytes) = 67108864                                                    // SHMMAX

max number of arrays = 128                                                               // SEMMNI

編輯 /etc/sysctl.conf
從最下方加上這幾行

# for DB2
# shmmax: 4GB
# shmall: 3.5GB
fs.file-max = 8192
kernel.shmmax = 4294967296
kernel.shmall = 917504
kernel.msgmni = 4096
kernel.sem = 250 256000 32 1024
kernel.randomize_va_space = 0 

套用後再確認一次

#> sysctl -p
#> ipcs -l

------ Shared Memory Limits --------
max number of segments = 4096
max seg size (kbytes) = 4194304
max total shared memory (kbytes) = 3670016

semaphore max value = 32767

------ Messages: Limits --------
