本文主要是介绍命令行安装 Oracle11g，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

命令行安装11g

以下文件名、路径、配置信息都是前后一致的，如根据实际情况调整，需要注意前后的一致性！
安装时仅安装软件，不创建数据库。

一、创建目录

检查一下配置的路径

[oracle@oracledb ~]$ echo $ORACLE_BASE
/app/oracle
[oracle@oracledb ~]$ echo $ORACLE_HOME
/app/oracle/product/11.2.0/db_1
[oracle@oracledb ~]$ echo $ORACLE_SID
orcl

用oracle用户建立数据库所需目录

$ mkdir -p $ORACLE_BASE/admin/$ORACLE_SID
$ cd $ORACLE_BASE/admin/$ORACLE_SID
$ mkdir adump bdump cdump dpdump hdump pfile udump
$ mkdir -p /app/oracle/fast_recovery_area/orcl
$ mkdir -p /app/oracle/oradata/orcl

以下都用oracle用户

二、配置初始化文件

创建一个初始化文件

$ vim ORACLE_BASE/admin/$ORACLE_SID/pfile/init.ora

插入下面内容

注意：

undo表空间名和创建数据库脚本表空间名一定一致！！！

三、创建oracle密码文件

$ orapwd file=$ORACLE_HOME/dbs/orapw$ORACLE_SID password=oracle

四、创建数据库

先登录sys 以DBA身份，用初始化参数文件将数据库启动到nomount状态。

$ sqlplus /nolog
SQL> conn / as sysdba;
SQL> startup nomount pfile="/app/oracle/admin/orcl/pfile/init.ora";

说明：

字符集：ZHS16GBK

sys和system密码：manager2021

数据库SID：orcl

创建数据库脚本如下：

CREATE DATABASE orcl
   MAXINSTANCES 8
   MAXLOGHISTORY 16
   MAXLOGFILES 16
   MAXLOGMEMBERS 3
   MAXDATAFILES 512
   DATAFILE '/app/oracle/oradata/orcl/system01.dbf' SIZE 2048M REUSE 
      AUTOEXTEND OFF
      EXTENT MANAGEMENT LOCAL
   SYSAUX DATAFILE '/app/oracle/oradata/orcl/sysaux01.dbf' SIZE 1024M REUSE 
      AUTOEXTEND OFF
   SMALLFILE DEFAULT TEMPORARY TABLESPACE TEMP TEMPFILE '/app/oracle/oradata/orcl/temp01.dbf' SIZE 4096M REUSE 
      AUTOEXTEND OFF
   SMALLFILE UNDO TABLESPACE "UNDOTBS1" DATAFILE '/app/oracle/oradata/orcl/UNDOTBS1.dbf' SIZE 8192M REUSE 
      AUTOEXTEND OFF
   CHARACTER SET ZHS16GBK
   NATIONAL CHARACTER SET AL16UTF16
   LOGFILE GROUP 1 ('/app/oracle/oradata/orcl/redo01.log') SIZE 102400K,
           GROUP 2 ('/app/oracle/oradata/orcl/redo02.log') SIZE 102400K,
           GROUP 3 ('/app/oracle/oradata/orcl/redo03.log') SIZE 102400K
   USER SYS IDENTIFIED BY "manager2021" 
   USER SYSTEM IDENTIFIED BY "manager2021";

/

五、执行数据字典脚本

用两个角色执行脚本：

SQL> conn sys/manager2021 as sysdba
SQL> @?/rdbms/admin/catalog
SQL> @?/rdbms/admin/catproc
SQL> conn system/manager2021 
SQL> @?/sqlplus/admin/pupbld

六、创建spfile

创建完spfile后，关闭数据库，然后就可以startup直接启动了。

SQL> create spfile from pfile='/app/oracle/admin/orcl/pfile/init.ora';
SQL> shutdown immediate;
SQL> startup

七、网络访问连接设置

1、配置文件

因为安装时仅安装软件，所以没有配置net 。

在$ORACLE_HOME/network/admin路径下，手工配置三个ora文件，需要注意的就是机器名一定正确，SID一定正确。

文件内容如下，直接复制粘贴即可：

（1） listener.ora

# listener.ora Network Configuration File: /app/oracle/product/11.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = oracledb)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = /app/oracle

（2）tnsnames.ora

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = oracledb)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

（3）sqlnet.ora

# sqlnet.ora Network Configuration File: /app/oracle/product/11.2.0/db_1/network/admin/sqlnet.ora
# Generated by Oracle configuration tools.

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

ADR_BASE = /app/oracle

2、启动监听

（1）用命令启动监听：lsnrctl start

[oracle@oracledb admin]$ lsnrctl start
