Thank you for providing the answers to my questions.

After generated the private key, what need to do for using private key is adding this line in CMakeLists.txt

set(mcuboot_CONFIG_BOOT_SIGNATURE_KEY_FILE \"${CMAKE_CURRENT_SOURCE_DIR}/priv.pem\")

And put priv.pem file in project folder(out from build folder)
