I have installed the liunx version of oracle several times recently. I am entangled in the graphical output, and the installation cannot be carried out. The information on the Internet is said to be xhost, download various graphical support.
I found a solution to try
When creating the oracle database, we will create the oracle user and give it permission to install the directory,
When entering the oracle user, do not use the root account to switch the oracle account that is su oracle,
Instead, use xshell, log in with the oracle account password, and click on Xmanager in the tunnel, and then log in to the oralce account, as shown below
Cd to runInstaller in the directory ./runInstaller to run the script, it can be graphically displayed, you can continue the installation,
