Centos5.8_x86_+ASM+ORACLE11G

操作系统Centos5.8_位

安装桌面，虚拟主机，关闭SELINUX以及关闭防火墙，

1、内存以及swap分区大小，服务器2G以上内存就可以安装，服务器空间，尽可能给大些。

Minimum: 1 GB of RAM

Recommended: 2 GB of RAM or more

To determine the RAM size, enter the following command:

#grep MemTotal /proc/meminfo

Swap分区大小设置

Between 1 GB and 2 GB 分配1.5 times the size of the RAM

Between 2 GB and 16 GB 分配Equal to the size of the RAM

More than 16 GB 分配16GB

#grep SwapTotal /proc/meminfo 确定大小

2、需要安装以下软件

binutils-2.20.51.0.2-5.11.el6 (x86_)

compat-libcap1-1.10-1 (x86_)

compat-libstdc++-33-3.2.3-69.el6 (x86_)

compat-libstdc++-33-3.2.3-69.el6.i686

gcc-4.4.4-13.el6 (x86_)

gcc-c++-4.4.4-13.el6 (x86_)

glibc-2.12-1.7.el6 (i686)

glibc-2.12-1.7.el6 (x86_)

glibc-devel-2.12-1.7.el6 (x86_)

make-3.81-19.el6

sysstat-9.0.4-11.el6 (x86_)

unixODBC*

libXp

pdksh

配置Yum安装

将光盘挂载到/mnt位置

[root@oracle ~]# mount /dev/cdrom /mnt

[root@oracle ~]# vi /etc/yum.repos.d/base.repo

[base]

name=base

baseurl=file:///mnt/

enabled=1

gpgcheck=0

执行下面语句安装

yum -y install binutils compat-* elfutils-libelf* gcc gcc-c++ glibc* kernel-headers ksh libaio* libgcc libgomp libstdc++* make sysstat libXp pdksh.x86_ unixODBC unixODBC-devel

3、注意主机名

[oracle@oracle11g ~]$ cat /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 oracle11g localhost.localdomain localhost

::1 localhost6.localdomain6 localhost6

172.16.40.30 oracle

4、建立相应的用户和组

[root@oracle ~]# groupadd oinstall

[root@oracle ~]# groupadd dba

[root@oracle ~]# groupadd asmadmin

[root@oracle ~]# groupadd asmdba

[root@oracle ~]# useradd -g oinstall -G asmdba,asmadmin,dba grid

[root@oracle ~]# useradd -g oinstall -G dba,asmdba oracle

[root@oracle ~]# passwd grid

[root@oracle ~]# passwd oracle

[root@oracle ~]# id grid

uid=500(grid) gid=500(oinstall) groups=500(oinstall),501(dba),502(asmadmin),503(asmdba)

[root@oracle ~]# id oracle

uid=501(oracle) gid=500(oinstall) groups=500(oinstall),501(dba),503(asmdba)

5、修改/etc/sysctl.conf文件，添加以下内容

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152
