session required
after edit OS parameter you need to create Oracle user :

groupadd -g 101 oinstall
groupadd -g 102 dba
groupadd -g 103 oper
 useradd -u 100 -g oinstall -G dba,oper oracle
passwd oracle
copy media to your Server , and do the following :

chown -R oracle:oinstall /u01/database
chmod -R 775 /u0/database
mkdir -p /u01/app/oracle/product/12.1.0/db_1
chown -R oracle:oinstall /u01
chmod -R 775 /u01

now start installation by ./runInstaller

to Create Database you need to configure listener using netca and after finished successfully use dbca like below :
