linux自动拷贝文件，并恢复ORACLE数据库

为了在脚本里使用scp命令不输入密码，需要在各主机间建立安全信息关系
1创建证书
[oracle@eastestdb2 ~]$ ssh-keygen -b 1024 -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/oracle/.ssh/id_rsa):
Created directory '/home/oracle/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/oracle/.ssh/id_rsa.
Your public key has been saved in /home/oracle/.ssh/id_rsa.pub.
The key fingerprint is:
46:fa:16:6e:6f:1b:9a:eb:e9:c0:25:e5:dc:52:83:47 oracle@eastestdb2
The key's randomart image is:
+--[ RSA 1024]----+
|          E      |
|         o       |
|        + +      |
|       * + .     |
|      o S .      |
|     . * o       |
|      o = .      |
|       + =..     |
|       oBoo.     |
+-----------------+

2、将公钥证书复制到Server 的.ssh目录中

[oracle@eastestdb2 .ssh]$ scp -p id_rsa.pub
oracle@192.168.100.36:/home/oracle/.ssh/authorized_keys

3、修改原有计划任务脚本，直接复制文件到备份服务器

[oracle@NEWEASDB ~]$ cat eascron_expdp_EAS_DAY.sh

expdp system/kingdee schemas=ORUSER directory=orabak dumpfile=zy_$(date "+%Y%m%d%H%M").dmp logfile=zy_$(date "+%Y%m%d%H%M").log

find /orabak -mtime +5 -name '*.dmp' | xargs rm

find /orabak -mtime +5 -name '*.log' | xargs rm

scp /orabak/zy_$(date "+%Y%m%d")0400.dmp
oracle@192.168.100.36:/orabak

#[oracle@NEWEASDB orabak]$ scp /orabak/zy_$(date "+%Y%m%d")0400.dmp
oracle@192.168.100.36:/orabak

4、在备份服务器上创建计划任务

crontab -e 创建任务

0 6 * * * source /home/oracle/.bash_profile; /bin/sh /home/oracle/eascron_impdp_EAS_DAY.sh

5、创建计划任务执行的脚本文件,导入数据到备份服务器

vi /home/oracle/eascron_impdp_EAS_DAY.sh

impdp system/redhat schemas=ORUSER dumpfile=zy_$(date "+%Y%m%d")0400.dmp logfile=zy_$(date "+%Y%m%d")0400.log directory=orabak table_exists_action=replace

find /orabak -mtime +0 -name '*.*' | xargs rm -rf
