一：设置环境变量
[oracle@orcl ~]$ cat .bash_profile
# .bash_profile
# get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# user specific environment and startup programs
oracle_sid=orcl
oracle_base=/u01/app/oracle
oracle_home=$oracle_base/product/10.2.0/db_1
editor=vim
nls_lang=american_america.al32utf8
nls_date_format=yyyy-mm-dd:hh24:mi:ss
path=$path:$home/bin:$oracle_home/bin:$path
export path oracle_sid oracle_base oracle_home editor nls_lang nls_date_format
alias sqlplus='/usr/local/rlwrap/bin/rlwrap sqlplus'
alias rman='/usr/local/rlwrap/bin/rlwrap rman'
二：准备密码文件和初始化参数文件以及创建数据库脚本
[root@orcl ~]# su - oracle
[oracle@orcl ~]$ cd $oracle_home/dbs
[oracle@orcl dbs]$ orapwd file=orapworcl password=123456 entries=5
*.db_name=orcl
*.db_block_size=8192
*.sga_target=1677721600
*.undo_management='auto'
*.control_files = ('/u01/app/oracle/oradata/orcl/control01.ctl','/u01/app/oracle/oradata/orcl/control012ctl','/u01/app/oracle/oradata/orcl/control03.ctl')
*.user_dump_dest='/u01/app/oracle/admin/orcl/udump'
*.background_dump_dest='/u01/app/oracle/admin/orcl/bdump'
*.core_dump_dest='/u01/app/oracle/admin/orcl/cdump'
[oracle@orcl ~]$ cat $oracle_home/dbs/initorcl.ora
*.db_name=orcl
*.db_block_size=8192
*.db_file_multiblock_read_count=16
*.db_unique_name='orcl'
*.sga_target=167772160
*.undo_management='auto'
*.undo_tablespace='undotbs1'
*.open_cursors=300
*.pga_aggregate_target=16777216
*.processes=1500
*.control_files = ('/u01/app/oracle/oradata/orcl/control01.ctl','/u01/app/oracle/oradata/orcl/control012ctl','/u01/app/oracle/oradata/orcl/control03.ctl')
*.user_dump_dest='/u01/app/oracle/admin/orcl/udump'
*.background_dump_dest='/u01/app/oracle/admin/orcl/bdump'
*.audit_file_dest='/u01/app/oracle/admin/orcl/adump'
*.core_dump_dest='/u01/app/oracle/admin/orcl/cdump'
*.db_recovery_file_dest='/u01/app/oracle/flash_recovery_area'
*.db_recovery_file_dest_size=2147483648
[oracle@orcl ~]$ cat create_db.sql

三：准备创建数据库需要的相关目录
[oracle@orcl ~]$ mkdir -p /u01/app/oracle/admin/orcl
[oracle@orcl ~]$ mkdir -p /u01/app/oracle/oradata/orcl
[oracle@orcl ~]$ mkdir -p /u01/app/oracle/admin/orcl/{adump,bdump,cdump,udump}
[oracle@orcl ~]$ mkdir -p /u01/app/oracle/flash_recovery_area
四：开始建库
[oracle@orcl ~]$ env |grep sid
oracle_sid=orcl
[oracle@orcl ~]$ sqlplus /nolog

五：验证

六：配置em
建立和配置em资料库
