Hello
Welcome to Centrify community!
Redhat 7.4 has been supported since Centrify Suite 2017.2 (5.4.2). As I saw the error from the install.sh output, the issue seems to be occuring at the adcheck section between the agent and the AD.
Can you run the adcheck under the installation package as follow:
./adcheck <DOMAIN> --verbose
And see if there is any error showing from the output?
Hope it helps. Thank you!
BR,
Ivan
