步驟：
1：查看ORACLE_HOME是否設置
$ echo $ORACLE_HOME /u01/app/oracle/product/11.2.0/dbhome_1
2：執行dbstart 數據庫自帶啟動腳本
[oracle@njdzjkdb ~]$ cd $ORACLE_HOME [oracle@njdzjkdb dbhome_1]$ cd bin/ [oracle@njdzjkdb bin]$ dbstart ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener Usage: /u01/app/oracle/product/11.2.0/db_1/bin/dbstart ORACLE_HOME 錯誤提示：ORACLE_HOME_LISTNER 沒有設置 [oracle@njdzjkdb bin]$ ll | grep dbs -rwxr-x---. 1 oracle oinstall 6088 1月 1 2000 dbshut -rwxr-x---. 1 oracle oinstall 13892 12月 11 16:01 dbstart 編輯 dbstart，將ORACLE_HOME_LISTNER=$1修改成 ORACLE_HOME_LISTNER=$ORACLE_HOME 前提是$ORACLE_HOME環境設置正確 [oracle@njdzjkdb bin]$ vi dbstart ORACLE_HOME_LISTNER=/u01/app/oracle/product/11.2.0/dbhome_1
3：編輯/etc/oratab文件
dbca建庫時都會自動創建/etc/oratab文件
將orcl:/u01/app/oracle/product/11.2.0/dbhome_1:N
修改成 orcl:/u01/app/oracle/product/11.2.0/dbhome_1:Y
4：編輯/etc/rc.d/rc.local啟動文件，添加數據庫啟動腳本dbstart
[root@njdzjkdb ~]# vi /etc/rc.d/rc.local #!/bin/bash # THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES # # It is highly advisable to create own systemd services or udev rules # to run scripts during boot instead of using this file. # # In contrast to previous versions due to parallel execution during boot # this script will NOT be run after all other services. # # Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure # that this script will be executed during boot. touch /var/lock/subsys/local su oracle -lc "/u01/app/oracle/product/11.2.0/dbhome_1/bin/lsnrctl start" su oracle -lc /u01/app/oracle/product/11.2.0/dbhome_1/bin/dbstart
5：重啟主機，查看數據庫和監聽是自啟動
6：查看數據庫是否處於open狀態
select status from v$instance
