Oracle Database - 18c - RAC 18c Database Installation

This blog goes in continuation with my 18c installation. 
I install 18c RAC Database on my cluster. 

You can download Oracle Database 18c from Database Downloads page from Oracle and hence sftp to the required server. 

Step 1. [As oracle] Set Passwordless for oracle user

cd /u01/app/180/grid/deinstall 

./sshUserSetup.sh -user oracle -hosts "rac18c01 rac18c02" -noPromptPassphrase -confirm -advanced

Step 2. [As root ] Create Required Directories (ON Both Nodes)

mkdir -p /u01/app/oracle/product/180/db
chown -R oracle:oinstall /u01/app/oracle

Step 3. [As oracle] Unzip the Database Binary (ON Node 1)

cd /u01/app/oracle/product/180/db
unzip -qq /tmp/LINUX.X64_180000_db_home.zip

Step 4. [As oracle on Node 1] Installation
Connect as Oracle User to the system

cd /u01/app/oracle/product/180/db
././runInstaller
