Red Hat 5.5安装oracle 10G

   一.学习的东西越多，越需要整理，于是就有诞生了该博客。作为第一篇博客，必须是oracle了，因为我要做DBA。废话不多说，搞起。

   二.准备工作：10201_database_linux32.zip.

             libXp-1.0.0-8.1.el5.i386.rpm（该包在镜像里有）

   三.按照公司的需求，做的配置：

1.调整内核参数和安装rpm包：

root登录，在X－windows下执行xhost + (设置Xserver访问权限)  

echo 400000000 > /proc/sys/kernel/shmmax

source /etc/profile 

rpm -ivh libXp-1.0.0-8.1.el5.i386.rpm

2.创建DBA组和Oracle用户：

groupadd dba

useradd oracle –g dba

passwd oracle

mkdir –p /home/oracle/product/1020

chown oracle.dba /home/oracle/product/1020

mkdir -p /home/oracle/tmp 

chown oracle.dba /home/oracle/tmp

3.登录oracle，设置oracle环境变量 (以后变量在/etc/profile也要添加)

登陆oracle使用命令：su - oracle

vi .bash_profile 

export ORACLE_BASE=/home/oracle

export ORACLE_HOME=/home/oracle/product/1020

export ORACLE_SID=orcl

export LD_LIBRARY_PATH=/lib:/usr/lib:$ORACLE_HOME/lib

export PATH=$PATH:$ORACLE_HOME/bin

export TMPDIR=/home/oracle/tmp

export NLS_LANG=AMERICAN_AMERICA.UTF8

export LANG=en_us.utf8

4.把10201_database_linux32.zip复制到/home/oracle目录中，并解压。（以下操作因为需要图形化操作，需在服务器端执行）

复制时使用命令： cp  10201_database_linux32.zip  /home/oracle

解压时使用命令： unzip 10201_database_linux32.zip

登录oracle：su – oracle

cd database

[oracle@localhost database]$ ./runInstaller 

Starting Oracle Universal Installer...

Checking operating system version: must be redhat-3, SuSE-9, redhat-4, UnitedLinux-1.0, asianux-1 or asianux-2

                                      Failed <<<<

Exiting Oracle Universal Installer, log for this session can be found at /tmp/OraInstall2014-11-21_12-31-14AM/installActions2014-11-21_12-31-14AM.log

出错了：oracle只支持AS4以下的系统，修改配置文件如下即可

vi /etc/redhat-release 

Red Hat Enterprise Linux Server release 4 (Tikanga)

5.继续安装即可成功。安装比较简单，内核也没优化，后续还会有更详细的oracle安装记录。

这一步需要用root用户执行该脚本：

[root@localhost oracle]# /home/oracle/oraInventory/orainstRoot.sh 

Changing permissions of /home/oracle/oraInventory to 770.

Changing groupname of /home/oracle/oraInventory to oracle.

The execution of the script is complete

[root@localhost oracle]# /home/oracle/product/1020/root.sh

Running Oracle10 root.sh script...

The following environment variables are set as:

    ORACLE_OWNER= oracle

    ORACLE_HOME=  /home/oracle/product/1020

Enter the full pathname of the local bin directory: [/usr/local/bin]: 

   Copying dbhome to /usr/local/bin ...

   Copying oraenv to /usr/local/bin ...

   Copying coraenv to /usr/local/bin ...

Creating /etc/oratab file...

Entries will be added to the /etc/oratab file as needed by

Database Configuration Assistant when a database is created

Finished running generic part of root.sh script.

Now product-specific root actions will be perfORMed.

四.下面是我第一次安装出现的错误：

1. 如果有这个错误，就是libXp-1.0.0-8.1.el5.i386.rpm包没安装。

[oracle@localhost database]$ ./runInstaller

                                      Passed

2.如果有下面问题，用root用户执行安装过程中出现的两个脚本。

/home/oracle/oraInventory/orainstRoot.sh

/home/oracle/product/1020/root.sh
