1、切换到oracle用户

[root@OracleLinux-R9-U5 ~]# su oracle

2、查看oracle是否配置了ORACLE_SID

[oracle@OracleLinux-R9-U5 root]$ cd ~
[oracle@OracleLinux-R9-U5 ~]$ cat .bash_profile

3、输出内容如下：

[oracle@OracleLinux-R9-U5 ~]$ cat .bash_profile
# .bash_profile# Get the aliases and functions
if [ -f ~/.bashrc ]; then. ~/.bashrc
fi
export ORACLE_HOME=/opt/oracle/product/23ai/dbhomeFree  # 根据实际路径修改
export PATH=$ORACLE_HOME/bin:$PATH
export ORACLE_SID=FREE
# User specific environment and startup programs
[oracle@OracleLinux-R9-U5 ~]$ 

4、如果已经设置了ORACLE_SID和oracle环境变量，则刷新环境变量

[oracle@OracleLinux-R9-U5 ~]$ source .bash_profile

5、连接数据库并且开启数据库

[oracle@OracleLinux-R9-U5 ~]$ sqlplus / as sysdbaSQL*Plus: Release 23.0.0.0.0 - Production on Sat Apr 12 09:41:45 2025

6、启动网络监听

[oracle@OracleLinux-R9-U5 ~]$ lsnrctl startLSNRCTL for Linux: Version 23.0.0.0.0 - Production on 12-APR-2025 09:43:31Copyright (c) 1991, 2025, Oracle.  All rights reserved.Starting /opt/oracle/product/23ai/dbhomeFree/bin/tnslsnr: please wait...TNSLSNR for Linux: Version 23.0.0.0.0 - Production
