Hello all!
So, now with more use of resources like Cloud servers, more and more silent instalations are being done, right? Myself, I do it in silent always I can.
What if I need to export X. Plus, if I need to export it from user oracle, but I can only login with ec2-user, as usual?
Here is the process for that:
1) Connect to AWS EC2 instance
[user@securehost ~]$ ssh -X ec2-user@ipaddress Last login: Fri Dec 7 14:41:41 2018 from grepora.srv.com
__| __|_ ) _| ( / Amazon Linux AMI ___|\___|___|
https://aws.amazon.com/amazon-linux-ami/2018.03-release-notes/ 13 package(s) needed for security, out of 16 available Run "sudo yum update" to apply all updates.
2) Test xclock works from ec2-user
[ec2-user@ipaddress ~]$ xclock Warning: Missing charsets in String to FontSet conversion ^C
3) Show all magic cookie
[ec2-user@ipaddress ~]$ xauth list ipaddress/unix:12 MIT-MAGIC-COOKIE-1 7e53e7600ff4177d7bbc66bde0a1b1ca ipaddress/unix:11 MIT-MAGIC-COOKIE-1 e3d1a8915484c929ef3e809b047e6352 ipaddress/unix:10 MIT-MAGIC-COOKIE-1 07b3de3093cef835c19239ea952231b7
4) Show DISPLAY variable
[ec2-user@ipaddress ~]$ env|grep DISPLAY DISPLAY=localhost:10.0
5) Create /tmp/xauth based on current DISPLAY variable
[ec2-user@ipaddress ~]$ xauth list | grep unix`echo $DISPLAY | cut -c10-12` > /tmp/xauth [ec2-user@ipaddress ~]$ ll /tmp/xauth ; cat /tmp/xauth -rw-rw-r-- 1 ec2-user ec2-user 78 Dec 7 14:47 /tmp/xauth ipaddress/unix:10 MIT-MAGIC-COOKIE-1 07b3de3093cef835c19239ea952231b7
6) Sudo to oracle
[ec2-user@ipaddress ~]$ sudo su - oracle Last login: Fri Dec 7 14:43:12 UTC 2018 on pts/0
7) Add and Verify xauth
[oracle@ipaddress ~]$ xauth add `cat /tmp/xauth` [oracle@ipaddress ~]$ xauth list ipaddress/unix:10 MIT-MAGIC-COOKIE-1 07b3de3093cef835c19239ea952231b7
8) Verify and Add DISPLAY variable
[oracle@ipaddress ~]$ env|grep DISPLAY [oracle@ipaddress ~]$ export DISPLAY=localhost:10.0
9) Test xclock works from oracle
[oracle@ipaddress ~]$ xclock Warning: Missing charsets in String to FontSet conversion ^C [oracle@ipaddress ~]$
Now you should be able to see the clock and so other graphical resources, like DBCA and so on.
Hope it helps!
