CentOS7.6.1810下设置Oracle11.2.0.1.0开机自启

1、很多安装不成功都是版本未对应，所以老规矩，先上版本号：

cat /etc/centos-release

显示信息，如下

CentOS Linux release 7.6.1810 (Core) 

2、使用root登入系统，修改/etc/oratab

vim /etc/oratab

将

orcl:/usr/local/oracle/product/11.2.0/dbhome_1:N

修改为

orcl:/usr/local/oracle/product/11.2.0/dbhome_1:Y

并将oracle安装路径/usr/local/oracle/product/11.2.0/dbhome_1复制出来备用

3、修改/usr/local/oracle/product/11.2.0/dbhome_1/bin/dbstart

vim /usr/local/oracle/product/11.2.0/dbhome_1/bin/dbstart

将第80行的(可通过set number显示行号)

ORACLE_HOME_LISTNER=$1

修改为

ORACLE_HOME_LISTNER=$ORACLE_HOME

4、修改/usr/local/oracle/product/11.2.0/dbhome_1/bin/dbshut

vim /usr/local/oracle/product/11.2.0/dbhome_1/bin/dbshut

将第50行的

ORACLE_HOME_LISTNER=$1

修改为

ORACLE_HOME_LISTNER=$ORACLE_HOME

5、修改/etc/rc.d/rc.local

vim /etc/rc.d/rc.local

添加内容

su oracle -lc "/usr/local/oracle/product/11.2.0/dbhome_1/bin/lsnrctl start"
su oracle -lc "/usr/local/oracle/product/11.2.0/dbhome_1/bin/dbstart"

6、新建服务启动脚本

vim /etc/init.d/oracle

添加内容

#!/bin/sh
# chkconfig: 345 61 61
# description: Oracle 11g R2 AutoRun Servimces
# /etc/init.d/oracle
#
# Run-level Startup script for the Oracle Instance, Listener, and
# Web Interface
export ORACLE_BASE=/usr/local/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1
export ORACLE_SID=ORCL
export PATH=$PATH:$ORACLE_HOME/bin
ORA_OWNR="oracle"
# if the executables do not exist -- display error
if [ ! -f $ORACLE_HOME/bin/dbstart -o ! -d $ORACLE_HOME ]
then
echo "Oracle startup: cannot start"
exit 1
fi
# depending on parameter -- startup, shutdown, restart
# of the instance and listener or usage display
case "$1" in
start)
# Oracle listener and instance startup
su $ORA_OWNR -lc $ORACLE_HOME/bin/dbstart
echo "Oracle Start Succesful!OK."
;;
stop)
# Oracle listener and instance shutdown
su $ORA_OWNR -lc $ORACLE_HOME/bin/dbshut
echo "Oracle Stop Succesful!OK."
;;
reload|restart)
$0 stop
$0 start
;;
*)
echo $"Usage: `basename $0` {start|stop|reload|reload}"
exit 1
esac
exit 0

7、授权并测试oracle脚本

# 授权
chmod 750 /etc/rc.d/init.d/oracle

# 启动oracle
/etc/rc.d/init.d/oracle start

# 关闭oracle
/etc/rc.d/init.d/oracle stop

8、将oracle脚本加入启动项

ln -s /etc/rc.d/init.d/oracle /etc/rc2.d/S61oracle
ln -s /etc/rc.d/init.d/oracle /etc/rc3.d/S61oracle
ln -s /etc/rc.d/init.d/oracle /etc/rc4.d/S61oracle
ln -s /etc/rc.d/init.d/oracle /etc/rc0.d/K61oracle
ln -s /etc/rc.d/init.d/oracle /etc/rc6.d/K61oracle

cd /etc/rc.d/init.d

chkconfig --level 234 oracle on
chkconfig --add oracle

9、重启，测试连接

# 重启
reboot

# 测试1521端口
curl localhost:1521
