在安装GI(Grid Infrastruct)时报下面的错

[root@single soft]# cd grid

[root@single grid]# export DISPLAY=10.1.5.240:0.0

[root@single grid]# ./runInstaller 

解决办法：

修改/etc/hosts文件

[root@single grid]# 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
::1    localhost6.localdomain6       localhost6

加上主机名

[root@single grid]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       single localhost.localdomain localhost
::1     single localhost6.localdomain6       localhost6
