• Make sure all prerequisites met before installing oracle software, like kernel parameter , permission, RPM's, etc. Use this link for reference(https://anuragkumarjoy.blogspot.com/2016/02/oracle-database-installation-on-oracle.html)
• Download the oracle 19c software from oracle support
• unzip oracle software in ORACLE_HOME location 
• ORACLE_HOME=/u01/app/oracle/product/19.0.0/db_home
• go to ORACLE_HOME (cd /u01/app/oracle/product/19.0.0/db_home)
• unzip command: (unzip -oq /tmp/LINUX.X64_193000_db_home.zip)
• after that run the  "./runInstaller"

In this case, I used sample schema installed

This window is pop-up because I used a non-standard password.
