解决安装Oracle时检查监视器不通过的问题

1.安装数据库软件，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

     >>> 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 <<<<

 退出 Oracle Universal Installer, 您可以在 /tmp/OraInstall2017-07-26_03-04-57PM/installActions2017-07-26_03-04-57PM.log 中找到本次会话的日志
 [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

5.使用"name of display"变量设置DISPLAY参数后，再次执行安装程序，安装页面弹出成功。

 [root@db130 ~]# xhost +
 access control disabled, clients can connect from any host
 [root@db130 ~]# su - oracle
 [oracle@db130 ~]$ export DISPLAY=:12.0
 [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 36937 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。 实际为 16777216 通过
 准备从以下地址启动 Oracle Universal Installer /tmp/OraInstall2017-07-26_03-16-44PM. 请稍候...[oracle@db130 database]$

到此，“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。”问题完美解决。
