logout
[root@oracle ~]# reboot

9 解压oracle文件，并配置

9.1上传oracle数据库安装包到root家目录下

注册账号从 oracle官网下载
选择需要的版本，本文以11g为例

下载需要安装的oracle版本

9.2解压

[root@oracle ~]# unzip linux.x64_11gR2_database_1of2.zip -d /data/oracle/
[root@oracle ~]# unzip linux.x64_11gR2_database_2of2.zip  -d /data/oracle/
# 解压完成后进行安装前的配置
[root@oracle ~]# mkdir /data/oracle/etc
[root@oracle ~]# cp /data/oracle/database/response/* /data/oracle/etc/
[root@oracle ~]# vi /data/oracle/etc/db_install.rsp
# 进入编辑状态修改如下项的值
oracle.install.option=INSTALL_DB_SWONLY
DECLINE_SECURITY_UPDATES=true
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/data/oracle/oracle/inventory
SELECTED_LANGUAGES=en,zh_CN
ORACLE_HOSTNAME=oracle
ORACLE_HOME=/data/oracle/oracle/product/11.2.0
ORACLE_BASE=/data/oracle/oracle
oracle.install.db.InstallEdition=EE
oracle.install.db.isCustomInstall=true
oracle.install.db.DBA_GROUP=dba
oracle.install.db.OPER_GROUP=dba

10 安装

10.1安装

[root@oracle ~]# su - oracle
[oracle@oracle ~]$ cd /data/oracle/database
# 可以看见database文件夹下有三个模板其中dbca.rsp是用来创建数据库的。db_install.rsp是用来安装Oracle软件的。netca.rsp是用来创建监听器的
[oracle@oracle database]$ ./runInstaller -silent -ignorePrereq -responseFile /data/oracle/etc/db_install.rsp

可查看日志

通过tail命令查看安装日志
tail -f /data/oracle/oracle/inventory/logs/installActions2019-12-13_01-56-19PM.log

安装成功如下

10.4 静默创建数据库

10.4.1配置

[oracle@oracle ~]$ exit
[root@oracle ~]# vi /data/oracle/etc/dbca.rsp 
# 修改如下配置
GDBNAME = "orcl"
SID = "orcl"
SYSPASSWORD = "123456"
SYSTEMPASSWORD = "123456"
SYSMANPASSWORD = "123456"
DBSNMPPASSWORD = "123456"
DATAFILEDESTINATION =/data/oracle/oracle/oradata
RECOVERYAREADESTINATION=/data/oracle/oracle/fast_recovery_area
CHARACTERSET = "AL32UTF8"
TOTALMEMORY = "1638"

10.4.2 创建

[root@oracle ~]# su - oracle

[oracle@oracle ~]$ dbca -silent -createDatabase -templateName General_Purpose.dbc -gdbName ORCL -sysPassword 123456 -systemPassword 123456  

[oracle@oracle ~]$ exit
[root@oracle ~]# reboot

11 查看监听器状态

[root@oracle ~]# su - oracle
[oracle@oracle ~]$ lsnrctl start

12 启动数据库

以管理身份登录
[oracle@oracle ~]$ sqlplus / as sysdba
启动数据库实例
SQL> startup
查看系统的所有表
SQL> select * from tab;

13 解锁普通用户

SQL> alter user scott account unlock;			# 解锁scott用户
SQL> alter user scott identified by 123456;		# 设置scott用户密码

SQL> quit
[oracle@oracle ~]$ sqlplus scott
SQL> select  *from tab

可以使用 数据库连接工具，如plsql plsql下载地址
