数据库和监听器开机自启动
编辑oratab文件：
修改：orcl:/u01/app/oracle/product/11.2.0/db_1:N
orcl:/u01/app/oracle/product/11.2.0/db_1:Y
[oracle@ocptest bin]$ vi /etc/oratab # # This file is used by ORACLE utilities. It is created by root.sh # and updated by the Database Configuration Assistant when creating # a database. # A colon, ':', is used as the field terminator. A new line terminates # the entry. Lines beginning with a pound sign, '#', are comments. # # Entries are of the form: # $ORACLE_SID:$ORACLE_HOME:<N|Y>: # # The first and second fields are the system identifier and home # directory of the database respectively. The third filed indicates # to the dbstart utility that the database should , "Y", or should not, # "N", be brought up at system boot time. # # Multiple entries with the same $ORACLE_SID are not allowed. # # orcl:/u01/app/oracle/product/11.2.0/db_1:Y
执行dbstart和dbshut（数据库启动而监听器没有自启动）
[oracle@ocptest ~]$ 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 Processing Database instance "orcl": log file /u01/app/oracle/product/11.2.0/db_1/startup.log
修改dbstart和dbshut文件：
[oracle@ocptest ~]$ cd $ORACLE_HOME/bin [oracle@ocptest bin]$ vi dbstart
找到这行修改为：
ORACLE_HOME_LISTNER=$1 ORACLE_HOME_LISTNER=$ORACLE_HOME
同上修改dbshut文件。
dbstart验证：

dbshut验证：
[oracle@ocptest bin]$ dbshut Processing Database instance "orcl": log file /u01/app/oracle/product/11.2.0/db_1/shutdown.log [oracle@ocptest bin]$ ps -ef|grep smon oracle 4369 3254 0 23:48 pts/0 00:00:00 grep smon [oracle@ocptest bin]$ lsnrctl status LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 21-APR-2019 23:48:32 Copyright (c) 1991, 2009, Oracle.

添加开机自启动：
编辑/etc/rc.d/rc.local添加su oracle -lc /u01/app/oracle/product/11.2.0/db_1/bin/dbstart 到最后一行
[oracle@ocptest ~]$ vi /etc/rc.d/rc.local #!/bin/sh # # This script will be executed *after* all the other init scripts. # You can put your own initialization stuff in here if you don't # want to do the full Sys V style init stuff. touch /var/lock/subsys/local su oracle -lc /u01/app/oracle/product/11.2.0/db_1/bin/dbstart
如果上面没有编辑dbstart和dbshut文件添加侦听器参数：
则还需添加 su oracle -lc "/u01/oracle/bin/lsnrctl start"到/etc/rc.d/rc.local文件中；
第二种方法：
在oracle家目录创建两个文件：
oracle.start
oracle.stop
编辑：
vi oracle.start
[oracle@ocptest ~]$ vi oracle.start #!/bin/bash source /u01/app/oracle/product/11.2.0/db_1 lsnrctl start; sqlplus / as sysdba <<EOF startup EOF
vi oracle.stop
[oracle@ocptest ~]$ vi oracle.stop #!/bin/bash source /u01/app/oracle/product/11.2.0/db_1 sqlplus / as sysdba <<EOF startup EOF lsnrctl stop;
权限：
chmod +x /etc/init.d/oracle
chmod a+x oracle.start oracle.stop
单独执行这两个脚本进行验证；
通过copy一个network模板
cp /etc/init.d/network /etc/init.d/oracle
[root@ocptest ~]# vi /etc/init.d/oracle
#! /bin/bash
#
# oracle Bring up/down oracle
#
# chkconfig: 2345 90 1
# description: Activates/Deactivates all oracle configured to \
# start at boot time.
#
# Source function library.
. /etc/init.d/functions
# See how we were called.
case "$1" in
start)
su - oracle -c "/home/oracle/oracle.start"
;;
stop)
su - oracle -c "/home/oracle/oracle.stop"
;;
*)
echo $"Usage: $0 {start|stop}"
exit 2
esac
chkconfig oracle on
然后重启服务器测试下，我这里测试都没问题。
验证端口：
[oracle@ocptest ~]$ netstat -an|grep :1521 tcp 0 0 192.168.181.2:62747 192.168.181.2:1521 ESTABLISHED tcp 0 0 :::1521 :::* LISTEN tcp 0 0 ::ffff:192.168.181.2:1521 ::ffff:192.168.181.2:62747 ESTABLISHED
