17092601_CentOS7(64)下Oracle11g設定開機自啟動

1. 環境準備

1.1 系統

作業系統:CentOS 7(64位)

1.2 工具/軟體

已安裝完成的Oracle11g(64位);
建立資料庫例項,本文中資料庫例項名:test;$ORACLE_SID:testsid

2. 方法/步驟

2.1 配置/etc/oratab

以root身份登入到linux系統,編輯/etc/oratab檔案,找到
testsid:/data/oracle/product/11.2.0/db_1:N
,改為
testsid:/data/oracle/product/11.2.0/db_1:Y
注意:/data/oracle/product/11.2.0/db_1為安裝的$ORACLE_HOME,根據情況自行修改路徑。

[[email protected] ~]$ su   #切換到root
Password:                   #輸入root密碼
[[email protected] oracle]# vim /etc/oratab
[[email protected] oracle]# cat /etc/oratab
#
tsid:/data/oracle/product/11.2.0/db_1:N


# 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. # # testsid:/data/oracle/product/11.2.0/db_1:Y [[email protected] oracle]#

2.2 配置/etc/rc.d/rc.local

新增如下行:
su oracle -lc “/data/oracle/product/11.2.0/db_1/bin/lsnrctl start”
su oracle -lc /data/oracle/product/11.2.0/db_1/bin/dbstart
其中第一行因為lsnrctl之後有空格,需要引號,第二行加不加引號都可以。修改完儲存退出即可。

程式碼如下:

[[email protected] /]# vim /etc/rc.d/rc.local
[[email protected] /]# cat /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.

su oracle -lc "/data/oracle/product/11.2.0/db_1/bin/lsnrctl start"
su oracle -lc /data/oracle/product/11.2.0/db_1/bin/dbstart

touch /var/lock/subsys/local
# mount -a
[[email protected] /]#

如果是在以前的centos版本中,這樣就可以了。但是centos7 的/etc/rc.local不會開機執行,認真檢視/etc/rc.local檔案的內容就發現問題的原因了

[[email protected] /]# cat /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.

翻譯一下:

這個檔案是為了相容性的問題而新增的。
強烈建議建立自己的systemd服務或udev規則來在開機時執行指令碼而不是使用這個檔案。
與以前的版本引導時的並行執行相比較,這個指令碼將不會在其他所有的服務後執行。
請記住,你必須執行“chmod +x /etc/rc.d/rc.local”來確保確保這個指令碼在引導時執行。

檢視一下/etc/rc.d/rc.local的許可權

[root@zm-centos7 /]# ll /etc/rc.d/rc.local
-rw-r--r-- 1 root root 484 Oct 11 17:17 /etc/rc.d/rc.local

發現沒有執行許可權,按照說明的內容執行命令:

[root@zm-centos7 bin]# chmod +x /etc/rc.d/rc.local
[root@zm-centos7 bin]# reboot     #重啟機器,確認結果

2.3 重啟機器,確認自啟動結果

以oracle使用者,開啟一個終端:

[[email protected] ~]$ lsnrctl status   # 檢視監聽狀態

確認自啟動成功。另外再說一下,雖然此方法實現了自啟動,但在學習的過程中,還看到了其他的方法實現自啟動,本人也將在之後的博文中進行實踐和總結。謝謝!
