安装CentOS oracle过程已被广泛应用但是也在不断的更新，这里介绍安装安装CentOS oracle过程设置使用，帮助大家安装更新安装CentOS oracle过程系统。在这里介绍CentOS oracle 9i 在CentOS 4.4上的安装。

本文主要总结远程安装CentOS oracle过程。
1. 安装CentOS注意事项：
1.1 No Firewall
1.2 Disable SELinux
1.3  you must make sure that the Development Tools and Legacy Software Development options are selected.
 
CentOS oracle过程安装选择Server类型，安装的的包：
Development Tools
Legacy Software Development
及一些 config tools
没有安装X windows等（在下面需要另外安装 xorg-x11）

1.4 packages need to be installed (以下 开头的不用管了，只作参考)

Patches:(这个很重要，必须要打上)
http://oss.oracle.com/projects/compat-oracle/files/RedHat/
下载 http://oss.oracle.com/projects/compat-oracle/dist/files/RedHat/compat-libcwait-2.1-1.i386.rpm
http://oss.oracle.com/projects/compat-oracle/dist/files/RedHat/compat-oracle-rhel4-1.0-5.i386.rpm
然后安装 rpm -ivh *.rpm
可能会提示一些依赖包没有，这时候可以使用yum安装
# yum list | grep 包名
# yum install 包名
1.5 安装jre1.3.1

CentOS oracle过程设置内核参数
Edit the /etc/sysctl.conf and add following lines:
kernel.sem = 250 32000 100 128
kernel.shmmax = 2147483648
kernel.shmmni = 128
kernel.shmall = 2097152
#kernel.msgmnb = 65536
#kernel.msgmni = 2878
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
Note: You need execute "sysctl -p" or reboot system to apply above settings.

另外一种是：
kernel.shmmax = 2147483648kernel.shmmni = 100kernel.shmall = 2097152# semaphores: semmsl, semmns, semopm, semmnikernel.sem = 100 256 100 100fs.file-max = 327679kernel.hostname= Centos42.localdomain  #<--- full qualified hostname !!kernel.domainname = localdomain  #<--- correct domain name !!
Edit the /etc/security/limits.conf file and add following lines:
* - nproc 16384
* - nofile 16384
#oracle soft nofile 65536
#oracle hard nofile 65536
#oracle soft nproc 16384
#oracle hard nproc 16384

oracle:
设置环境变量
ORACLE_SID=lx92
ORACLE_BASE=/opt/oracle
ORACLE_HOME=$ORACLE_BASE/9.2.0
PATH=$ORACLE_HOME/bin:$PATH:.
LD_ASSUME_KERNEL=2.4.19
export ORACLE_SID ORACLE_BASE ORACLE_HOME PATH LD_ASSUME_KERNEL
LD_LIBRARY_PATH=$ORACLE_HOME/lib
#LD_ASSUME_KERNEL=2.4.1
ORACLE_OEM_JAVARUNTIME=/opt/jre1.3.1  ///需先安装java到该目录下，一定要使用 jre 1.3.1_1.x
export DISPLAY=10.15.2.62:0.0  //远程安装的时候，我的工作桌面的ip，需要安装xmanager

解压CentOS oracle过程安装包unpack files:
zcat lnx_920_disk1.cpio.gz | cpio -idmv
zcat lnx_920_disk2.cpio.gz | cpio -idmv
zcat lnx_920_disk3.cpio.gz | cpio -idmv
将Disk1/install/linux/oraparame.ini文件中JRE_LOCATION指向/opt/jre1.3.1
