一：开启 vnc 桌面

用另一个帐号登陆开启 vnc，这里用 Deepin-MHC 帐号，该帐号不能进入图形界面，否则 vnc 黑屏

成功进入 vnc 桌面

二：设置 DISPLAY

在 Deepin-MHC 帐号 执行

Deepin-MHC@deepin:~$ export DISPLAY=:1
Deepin-MHC@deepin:~$ xhost +
access control disabled, clients can connect from any host
# 出现上面这句就成功了

在 oracle 账户执行

oracle@deepin:~$ export DISPLAY=:1
oracle@deepin:~$ xhost +
access control disabled, clients can connect from any host
# 同上

三 : 切换到 oracle 的 bin 目录

在 bin 目录执行

oracle@deepin:/usr/local/oracle/Oracle/product/11.2.0/db_1/bin$ dbc

在 vnc 桌面上就打开了 dbca 的图形界面，这里中文变括号，记得是要在 oracle 帐号设置用户变量。

这个问题明天再解决

四:今天遇到的问题

Deepin-MHC@deepin:~$ su - oracle
请输入密码:
验证成功
oracle@deepin:~$ tigervncserver

===============================================================================

Starting applications specified in /home/oracle/.vnc/xstartup has failed.
Maybe try something simple first, e.g.,
        tigervncserver -xstartup /usr/bin/xterm

我在开启oracle账户的vnc时,没有正常开启,导致连接黑屏

按照提示输入

oracle@deepin:~$ tigervncserver -xstartup /usr/bin/xterm

New 'deepin:1 (oracle)' desktop at :1 on machine deepin

Starting applications specified in /usr/bin/xterm
Log file is /home/oracle/.vnc/deepin:1.log

Use xtigervncviewer -SecurityTypes VncAuth -passwd /home/oracle/.vnc/passwd :1 to connect to the VNC server.

现在没有错误提示,但是连接到vnc桌面,只有命令行界面

这个为什么没有图形界面了?

现在只能用oracle登录图形界面,用另一个帐号开启vnc,折腾一下午了还没找到办法
