1. 安装 Oracle 数据库软件，提示“检查监视器”未通过

[root@db130 ~]# xhost +

access control disabled, clients can connect from any host

[root@db130 ~]# su – oracle

[oracle@db130 ~]$ cd /u01/app/database

[oracle@db130 database]$ ./runInstaller

正在启动 Oracle Universal Installer…

检查临时空间: 必须大于 120 MB。实际为 36939 MB 通过

检查交换空间: 必须大于 150 MB。实际为 8047 MB 通过

检查监视器: 监视器配置至少必须显示 256 种颜色

>>> 无法使用命令 /usr/bin/xdpyinfo 自动检查显示器颜色。请检查是否设置了 DISPLAY 变量。未通过 <<<<

未通过某些要求检查。必须先满足这些要求,

然后才能继续安装,

是否继续? (y/n) [n] n

用户选择: 否

退出 Oracle Universal Installer, 您可以在 /tmp/OraInstall2017-07-26_03-02-54PM/installActions2017-07-26_03-02-54PM.log 中找到本次会话的日志
2. 根据报错信息，首先想到的是配置 DISPLAY 变量（一般配置一下就可以解决）

[oracle@db130 database]$ export DISPLAY=:0.0

[oracle@db130 database]$ ./runInstaller

[oracle@db130 database]$
3. 配置 DISPLAY 变量之后还是不行。根据报错信息 ” 无法使用命令 /usr/bin/xdpyinfo 自动检查显示器颜色 ”，怀疑是 xdpyinfo 有问题。

[root@db130 ~]# xdpyinfo

-bash: xdpyinfo: command not found
果然，系统中并未安装 xdpyinfo，那么先安装 xdpyinfo

[root@db130 ~]# yum install -y xdpyinfo
