为提高效率，提问时请提供以下信息，问题描述清晰可优先响应。
【DM版本】:dm8
【操作系统】：centos7
【CPU】:Intel(R) Xeon(R) W-2123 CPU @ 3.60GHz
【问题描述】*：在安装配置dm8时，命令行安装、配置实例可正常操作，但是在图形化安装、配置实例时无法正常显示gui界面

启用图形界面前需要通过如下方法将图形界面权限放开：
Copy
[root@localhost mnt]# xhost +
access control disabled, clients can connect from any host
[root@localhost mnt]# echo $DISPLAY
[root@localhost mnt]# su - dmdba
Last login: 四 1月 25 16:41:51 CST 2024 on pts/1
[dmdba@localhost ~]$ export DISPLAY=:0.0
进入 DM 安装目录下的 tool 目录，使用如下命令打开 DM 服务查看器，如下所示：

Copy
[dmdba@localhost ~]$ cd /home/dmdba/dmdbms/tool/
[dmdba@localhost tool]$ ll
[dmdba@localhost tool]$ ./dbca.sh

执行到这里就会卡住，没有对应的gui界面弹出

这里是执行./dbca.sh指令及前期的配置xhost操作
