建立用户组和用户

[root@oracle12c dev]#  groupadd -g 1000 oinstall

[root@oracle12c dev]# groupadd -g 1200 dba

[root@oracle12c dev]#  useradd -u 1100 -g oinstall -G dba oracle

[root@oracle12c dev]#  passwd oracle

Changing password for user oracle.

New UNIX password:

BAD PASSWORD: it is based on a dictionary word

Retype new UNIX password:

passwd: all authentication tokens updated successfully.

建立目录

[root@oracle12c dev]# mkdir -p /u01/app/

[root@oracle12c dev]# chown -R oracle:oinstall /u01/app/

[root@oracle12c dev]# chmod -R 775 /u01/app/

设置oracle用户环境变量

[root@oracle12c dev]# su - oracle

[oracle@oracle12c ~]$ vi .bash_profile
