一、Oracle监听

操作声明：登录服务器，切换到oracle用户，或者以oracle用户登录
#切换oracle用户
[root@localhost ~]$ su - oracle
密码：
[oracle@localhost ~]$

1.1. 查看Oracle监听运行状态

[oracle@localhost ~]$ lsnrctl status

从图中可以看到oracle监听没有运行
在这里插入图片描述

1.2. 启动Oracle监听

[oracle@localhost ~]$ lsnrctl start

在这里插入图片描述

在这里插入图片描述
再次查看Oracle监听运行状态

[oracle@localhost ~]$ lsnrctl status

从图中可以看到oracle监听已经运行
在这里插入图片描述

1.3. 关闭监听器

二、Oracle 服务

2.1. 以SYS用户身份登录Oracle

[oracle@localhost ~]$ sqlplus /nologSQL*Plus: Release 11.2.0.4.0 Production on Sat May 16 15:43:46 2020Copyright (c) 1982, 2013, Oracle.  All rights reserved.SQL> conn /as sysdba
Connected to an idle instance.

2.2. 切换用户至sys

切换用户：
CONN 用户名/密码 [AS SYSDBA]，如果是sys用户一定要写上AS　SYSDBA

sqlplus /nolog
conn /as sysdba

2.3. 启动Oracle实例

SQL> startup
ORACLE instance started.Total System Global Area 8551575552 bytes
Fixed Size                  2270360 bytes
Variable Size            4244638568 bytes
Database Buffers         4294967296 bytes
Redo Buffers                9699328 bytes
Database mounted.
Database opened.

在这里插入图片描述

2.4. 停止Oeacle实例运行

SQL> shutdown
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> quit
Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
