To configure a sample Oracle Database you can execute the following service configuration script as root: /etc/init.d/oracledb_ORCLCDB-19c configure
...

根据提示，需要使用root用户初始化数据库：

snippet.bash

[root@localhost ~]# /etc/init.d/oracledb_ORCLCDB-19c configure

Database configuration completed successfully. The passwords were auto generated, you must change them by connecting to the database using 'sqlplus / as sysdba' as the oracle user.

使用oracle账户登录：

snippet.bash

[oracle@localhost ~]$ sqlplus / as sysdba

准备服务脚本：

snippet.bash

[root@localhost ~]# vim /etc/init.d/oracle
#!/bin/bash
#chkconfig:345 61 61
#description:Apache
#
# Set ORA_HOME to be equivalent to the $ORACLE_HOME
# from which you wish to execute dbstart and dbshut;
#
# Set ORA_OWNER to the user id of the owner of the
# Oracle database in ORA_HOME.
ORA_HOME=/opt/oracle/product/19c/dbhome_1
ORA_OWNER=oracle
if [ ! -f $ORA_HOME/bin/dbstart ]
then
echo "Oracle startup: cannot start"
exit
fi
case "$1" in
'start')
# Start the Oracle databases:
echo "Starting Oracle Databases ... "
echo "-------------------------------------------------"
date +" %T %a %D : Starting Oracle Databases as part of system up."
echo "-------------------------------------------------"
su - $ORA_OWNER -c "$ORA_HOME/bin/dbstart $ORA_HOME"
echo "Done"
 
# Start the Listener:
echo "Starting Oracle Listeners ... "
echo "-------------------------------------------------"
date +" %T %a %D : Starting Oracle Listeners as part of system up."
echo "-------------------------------------------------"
su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl start"
echo "Done."
echo "-------------------------------------------------"
date +" %T %a %D : Finished."
echo "-------------------------------------------------"
touch /var/lock/subsys/oracle
;;
 
'stop')
# Stop the Oracle Listener:
echo "Stoping Oracle Listeners ... "
echo "-------------------------------------------------"
date +" %T %a %D : Stoping Oracle Listener as part of system down."
echo "-------------------------------------------------"
su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl stop"
echo "Done."
rm -f /var/lock/subsys/oracle
 
# Stop the Oracle Database:

echo "-------------------------------------------------"
date +" %T %a %D : Stoping Oracle Databases as part of system down."
echo "-------------------------------------------------"
su - $ORA_OWNER -c "$ORA_HOME/bin/dbshut $ORA_HOME"
echo "Done."
echo ""
echo "-------------------------------------------------"
date +" %T %a %D : Finished."
echo "-------------------------------------------------"
;;
 
'restart')
$0 stop
$0 start
;;
esac

这样，以后可以通过service命令启停Oracle服务了：

snippet.bash

[root@localhost ~]# service oracle start
[root@localhost ~]# service oracle stop

如果实例未启动，您可以使用以下命令启动实例：

STARTUP;
