as5安装oracle步骤

一:建立用户,用户组:
groupadd dba
groupadd oinstall
useradd oracle -g oinstall -G dba
passwd oracle
二:修改说明,改为as4
vi /etc/redhat-release
修改后的内容:
Red Hat Enterprise Linux AS release 4 (Nahant Update 4)
#Red Hat Enterprise Linux Server release 5.4 (Tikanga)
三:改host(不必,网上说网络检查通不过,其实可以不进行网络监察,在安装oracle时有一步是检查,把网络监察的勾去掉即可)
vi /etc/hosts
修改后的内容:
192.168.10.172               localhost.localdomain localhost
四:export LC_ALL=en_US(如果as5安装时是english时,不必)
五:在/etc/sysctl.conf添加
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default=262144
net.core.rmem_max=262144
net.core.wmem_default=262144
net.core.wmem_max=262144
使之生效:
/sbin/sysctl -p
六:在/etc/security/limits.conf中添加
*               soft    nproc   2047
*               hard    nproc   16384
*               soft    nofile  1024
*               hard    nofile  65536
七:在/etc/pam.d/login中添加
session    required     /lib/security/pam_limits.so
八:禁止secure linux
vi /etc/selinux/config
修改以下行:
SELINUX=disabled
九:vi ~/.bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
