linux服务器下oracle开机自启

原文：https://www.w3xue.com/exp/article/201910/60559.html

1、首先切换到Oracle用户

[oracle@oracletest ~]$ cd /u01/app/oracle/product/11.2.0/db_1/bin/       -----标红字体部分数据库可能不一样，有的是dbhome_1，以自己实际配置目录为准

[oracle@oracletest bin]$ vi dbstart 

1. LOGMSG="logger -puser.alert -s "
3. trap 'exit' 1 2 3
5. # for script tracing
6. case $ORACLE_TRACE in
7. T) set -x ;;
8. esac
10. # Set path if path not set (if called from /etc/rc)
11. SAVE_PATH=/bin:/usr/bin:/etc:${PATH} ; export PATH
12. SAVE_LLP=$LD_LIBRARY_PATH
14. # First argument is used to bring up Oracle Net Listener
15. ORACLE_HOME_LISTNER=$ORACLE_HOME ############此处原来是$1，改成$ORACLE_HOME
16. if [ ! $ORACLE_HOME_LISTNER ] ; then
17. echo "ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener"
18. echo "Usage: $0 ORACLE_HOME"
19. else
20. LOG=$ORACLE_HOME_LISTNER/listener.log

2、用root用户编辑oratab和rc.local

[root@oracletest ~]# vi /etc/oratab

1. # This file is used by ORACLE utilities. It is created by root.sh
2. # and updated by either Database Configuration Assistant while creating
3. # a database or ASM Configuration Assistant while creating ASM instance.
5. # A colon, ':', is used as the field terminator. A new line terminates
6. # the entry. Lines beginning with a pound sign, '#', are comments.
7. #
8. # Entries are of the form:
9. # $ORACLE_SID:$ORACLE_HOME:<N|Y>:
10. #
11. # The first and second fields are the system identifier and home
12. # directory of the database respectively. The third filed indicates
13. # to the dbstart utility that the database should , "Y", or should not,
14. # "N", be brought up at system boot time.
15. #
16. # Multiple entries with the same $ORACLE_SID are not allowed.
17. #
18. #
19. oadb:/u01/app/oracle/product/11.2.0/db_1:Y ###此处原来是N，改为Y

[root@oracletest ~]# vi /etc/rc.d/rc.local 

1. #!/bin/sh
2. #
3. # This script will be executed *after* all the other init scripts.
4. # You can put your own initialization stuff in here if you don't
5. # want to do the full Sys V style init stuff.
7. touch /var/lock/subsys/local
8. #####在空白处添加下面两行，其中标红字体部分数据库可能不一样，有的是dbhome_1，以自己实际配置目录为准
9. su oracle -lc "/u01/app/oracle/product/11.2.0/db_1/bin/lsnrctl start"
10. su oracle -lc /u01/app/oracle/product/11.2.0/db_1/bin/dbstart

经过上面两步操作，数据库服务器重启后，数据库也会自动启动。
