11.2 GI安装 (单节点)

8. 下载介质

不能用root跑起安装，只能用oracle或grid这类用户,一般我们用grid，以跟数据库用户分开。

开启vncserver

vnc图形界面连到服务器，root用户执行xhost +

grid用户执行   ./runInstaller

因为我是单机安装asm的，而不是集群，所以选第二个。

选Engligsh。

选external，意思是ASM层不用做镜像。external意指底层存储做了raid，我们ASM就不用做镜像了。

输入稍微简单的密码，尽管会出来提示，但我们可以忽略。

尽管我用grid用户独立于oracle用户，但是我并没有为grid用户新建注入asmadmin之类的组,所以指定oinstall或dba组就可以了（当然grid用户要拥有oinstall与dba组了）

这里会根据跑起用户，即grid用户的环境变量，来写一个默认的BASE与HOME。

我grid用户的环境变量。

ORACLE_BASE=/u02/grid; export ORACLE_BASE

ORACLE_HOME=/u02/11.2.0/grid; export ORACLE_HOME

export PATH=$ORACLE_HOME/bin:$PATH

export ORACLE_SID=+ASM

点击下一步后进入检查步骤，检查完毕通过后，我们就可以点击install进行安装了。

跑完后，我们要用root跑脚本。

跑root脚本。

[root@erpdb dev]# sh /u02/11.2.0/grid/root.sh

Performing root user operation for Oracle 11g

The following environment variables are set as:

    ORACLE_OWNER= grid

    ORACLE_HOME= /u02/11.2.0/grid

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 ...

然后再点下一步，过会就可以安装完成了。

完成之后，用grid用户，sqlplus ‘/as sysasm‘进去，看diskgroup是否顺利挂载。
