配置Oracle lsnrctl 和自動啟動

1.設定主機名稱

[[email protected] ~]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=www.redhat6.com

2.設定主機名稱與IP地址的對應

[[email protected] ~]# cat /etc/hosts
127.0.0.1    localhost localhost.localdomain localhost4 localhost4.localdomain4
::1          localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.2.16 www.redhat6.com
 

3.修改:/u01/app/oracle/network/admin/listener.ora

[[email protected] admin]$ cat listener.ora 
# listener.ora Network Configuration File: /u01/app/oracle/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = www.redhat6.com)(PORT = 1521))
    )
  )


ADR_BASE_LISTENER = /u01/app
 

4.修改:/u01/app/oracle/network/admin/tnsnames.ora

[[email protected] admin]$ cat tnsnames.ora 
# tnsnames.ora Network Configuration File: /u01/app/oracle/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = www.redhat6.com)
    )
  )
 

5.lsnrctl 的常用方法

[[email protected] admin]$ lsnrctl

LSNRCTL for Linux: Version 11.2.0.3.0 - Production on 29-NOV-2013 21:56:57

Copyright (c) 1991, 2011, Oracle.  All rights reserved.

Welcome to LSNRCTL, type "help" for information.
LSNRCTL> help
The following operations are available
An asterisk (*) denotes a modifier or extended command:

start               stop                status              
services            version             reload              
save_config         trace               spawn               
change_password     quit                exit                
set*                show* 

lsnrctl start  -- 啟動監聽
lsnrctl stop   -- 停止監聽
lsnrctl status -- 檢視狀態

6.設定Oracle資料庫和lsnrct自動啟動方法

(我的機器是RedHat6_64,Oracle11g)

6.1.編輯: /etc/oratab

[[email protected] ~]# cat /etc/oratab 
#



# This file is used by ORACLE utilities.  It is created by root.sh
# and updated by either Database Configuration Assistant while creating
# a database or ASM Configuration Assistant while creating ASM instance.

# 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:N
orcl:/u01/app/oracle:Y    #這裡把"N"改為"Y"

6.2.修改 /etc/rc.local

[[email protected] ~]# cat /etc/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

# 新增下面兩條
su - oracle -c 'dbstart'
su - oracle -c 'lsnrctl start'

6.3.重新啟動系統.Oracle資料庫正常啟動.監聽也啟動了.

[[email protected] ~]$ sqlplus / as sysdba

其它問題:

關閉linux防火牆:

暫時關閉:
service iptables stop

永久性,需重啟:
chkconfig iptables off

[[email protected] ~]# chkconfig --list | grep iptables
iptables       	0:off	1:off	2:on	3:on	4:on	5:on	6:off
[[email protected] ~]# chkconfig iptables off
[[email protected] ~]# chkconfig --list | grep iptables
iptables       	0:off	1:off	2:off	3:off	4:off	5:off	6:off

關閉selinux:

1 永久方法 – 需要重啟伺服器
修改/etc/selinux/config檔案中設定SELINUX=disabled ，然後重啟伺服器。

2 臨時方法 – 設定系統引數
使用命令setenforce 0
附：
setenforce 1 設定SELinux 成為enforcing模式
setenforce 0 設定SELinux 成為permissive模式
