oracle安装报错解决办法记录

1、之前安装过一次oracle，再次安装报错（更换了安装路径）

首先，在执行runInstaller时，系统报错：
　　You do not have sufficient permissions to access the inventory '/oracle11g/oraInventory'. Installation cannot continue. Make sure that you have read/write permissions to the inventory directory and restart the installer.: Permission denied

解决办法：

执行./runInstaller -invPtrLoc /oracle11g/oraInst.loc 命令就可以绕过去了，oracle会创建一个新的loc文件。

2、./runInstaller报错

Starting Oracle Universal Installer...

Checking Temp space: must be greater than 80 MB. Actual 45586 MB Passed
Checking swap space: must be greater than 150 MB. Actual 2047 MB Passed
Checking monitor: must be configured to display at least 256 colors
>>> Could not execute auto check for display colors using command /usr/bin/xdpyinfo. Check if the DISPLAY variable is set. Failed <<<<

Some requirement checks failed. You must fulfill these requirements before

continuing with the installation,

 

1、root 下先执行#xhost +
2、su oracle
3、export DISPLAY=:0.0
