oracle在linux上的安装

ORACLE 在LINUX 上安装步骤第一步：确定root用户
who am i
第二步：打开时钟显示*
[root@xiaofeng ~]# xhost +
第三步：确定硬盘，内存，CPU参数
[root@xiaofeng ~]#df -h
[root@xiaofeng ~]# free
[root@xiaofeng ~]# grep "model name" /proc/cpuinfo
第四步：确定系统版本号
[root@xiaofeng ~]#uname –r
第五步：确定这些包的版本满足要求
[root@xiaofeng ~]# rpm -qa | grep binutils
\\\\\\\
\\\
第六步：确定系统版本
[root@xiaofeng ~]# cat /etc/issue
Red Hat Enterprise Linux AS release 4 (Nahant Update 3)
第七步：修改网络连接*
[root@xiaofeng ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
192.168.61.1xiaofeng.oracle.ocm xiaofeng
[root@xiaofeng ~]# hostname
xiaofeng.oracle.ocm
[root@xiaofeng ~]# vi /etc/hosts
[root@xiaofeng ~]# ping 192.168.0.1
PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.

rtt min/avg/max/mdev = 0.104/0.692/2.380/0.974 ms, pipe 2
第八步：确定域名
[root@xiaofeng ~]# domainname
(none)
第九步：建三个组*
[root@xiaofeng ~]# cat /etc/group
[root@xiaofeng ~]# groupadd oper
[root@xiaofeng ~]# usermod –g oinstall –G dba,oper oracle
[root@xiaofeng ~]# id oracle
uid=500(oracle) gid=505(oinstall) groups=505(oinstall),503(dba),504(oper) 第十步：确定其他用户
[root@xiaofeng ~]# id nobody
uid=99(nobody) gid=99(nobody) groups=99(nobody)
第十一步：确定oracle用户的密码
[root@xiaofeng ~]# passwd oracle
第十二步：修改内核参数
1）vi /etc/sysctl.conf
kernel.shmall=2097152
kernel.shmmax=2147483648
kernel.shmmni=4096
kernel.sem=250 32000 100 128
fs.file-max=65536
net.ipv4.ip_local_port_range= 1024 65000
net.core.rmem_default= 1048576
net.core.rmem_max= 1048576
net.core.wmem_default= 262144
net.core.wmem_max= 262144
2）vi /etc/security/limits.conf
oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536
3) vi /etc/pam.d/login
session required /lib/security/pam_limits.so session required pam_limits.so
4)vi /etc/profile
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
第十三步：确定安装目录，并指定权限*
[root@xiaofeng ~]# su - oracle
[oracle@xiaofeng ~]$ vi .bash_profile
export PATH
export ORACLE_BASE=/oracle
export ORACLE_HOME=$ORACLE_BASE/10g
export ORACLE_SID=orcl
[root@xiaofeng ~]$ ll /oracle
总用量16
drwx------ 2 oracle 502 16384 7月23 20:44 lost+found [root@xiaofeng ~]$ chown -R oracle:oinstall /oracle
[root@xiaofeng ~]$ chmod -R 775 /oracle
[root@xiaofeng ~]# mkdir /oracle/oradata
[root@xiaofeng ~]# chown oracle:oinstall /oracle/oradata
[root@xiaofeng ~]# chmod 775 /oracle/oradata
[root@xiaofeng ~]# mkdir /oracle/flash_recovery_area
[root@xiaofeng ~]# chown oracle:oinstall /oracle/flash_recovery_area
[root@xiaofeng ~]# chmod 775 /oracle/flash_recovery_area
[root@xiaofeng ~]#
第十四步：查看shell，display的信息，一定要确保能打开时钟。

Xhost + [root@xiaofeng ~]# su – oracle
[oracle@xiaofeng ~]$ echo $SHELL
/bin/bash
[oracle@xiaofeng~]$ xclock 显示时钟，如果出错xhost+，在出错，向下[oracle@xiaofeng ~]$ export DISPLAY=:0.0
[oracle@xiaofeng ~]$ xclock 显示小钟
第十五步：绑定光驱
[root@xiaofeng~]# cd /mnt
[root@xiaofeng mnt]#cd /media
[root@xiaofeng media]# mkdir cdrom
[root@xiaofeng media]# mount –t iso9660 /dev/cdrom /media/cdrom
第十六步：运行
[oracke@xiaofeng~]$ export LANG=C
[oracle@xiaofeng~]$ /media/cdrom/runInstaller –ignoreSysPreReqs。
