一、删除文件后有点担心不能恢复,现在不用怕了,有这个工具就可以了,很好用的
1,下载工具
[root@44 ~]# wget http://ext3grep.googlecode.com/files/ext3grep-0.6.0.tar.gz
2,安装
先检查下这三个包是否已经安装,没有的话先安装下,检查有没有安装gcc c++工具是否安装
[root@44 ~]# rpm -qa |grep e2fs
e2fsprogs-devel-1.39-23.el5
e2fsprogs-libs-1.39-23.el5
e2fsprogs-1.39-23.el5
[root@44 ~]#yum install c++* -y
3,安装
[root@44 ~]# tar xzvf ext3grep-0.6.0.tar.gz
[root@44 ~]# cd ext3grep-0.6.0
[root@44 ext3grep-0.6.0]# ./configure ; make ; make install
4,编译安装完成后就可以使用这个工具了
[root@44 ext3grep-0.10.1]# ext3grep -v
Running ext3grep version 0.6.0

5,下面测试下恢复效果
[root@44 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda5 47G 2.3G 43G 6% /
/dev/sda3 487M 11M 451M 3% /home
/dev/sda1 190M 12M 169M 7% /boot
tmpfs 125M 0 125M 0% /dev/shm
/dev/sdb9 on /mnt type ext3 (rw)
6,使用/dev/sdb9来做测试
[root@44 ~]# cd /mnt
[root@44 mnt]# cp /etc/dhcp6c.conf .
[root@44 mnt]# cp -r /etc/yum.repos.d .
[root@44 mnt]# ll
total 14
-rw-r--r-- 1 root root 178 Jan 22 23:58 dhcp6c.conf
drwx------ 2 root root 12288 Jan 22 22:52 lost+found
drw-r--r-- 1 root root 346 Jan 22 23:59 yum.repos.d
[root@44 mnt]# rm -rf *
[root@44 mnt]# ls
[root@44 mnt]#
现在将 /mnt下的东西都删掉了
7,进行恢复
1,执行这条命令查看删除的所有文件
[root@44 ~]# ext3grep /dev/sdb9 --ls --inode 2
2,恢复单个文件
[root@44 ~]# ext3grep /dev/sdb9 --restore-file dhcp6c.conf
Running ext3grep version 0.6.0
Number of groups: 13
Minimum / maximum journal block: 526 / 4640
Loading journal descriptors... sorting... done
N umber of descriptors in journal: 828; min / max sequence numbers: 2 / 4
Loading sdb9.ext3grep.stage2.... done
Restoring dhcp6c.conf
3,恢复的文件放在RESTORED_FILES目录
[root@44 ~]# cd RESTORED_FILES/
[ root@44 RESTORED_FILES]# ls
dhcp6c.conf
4恢复所有文件
[root@44 ~]# ext3grep /dev/sdb9 --restore-all
5,编辑恢复的文件
[root@44 RESTORED_FILES]# vi dhcp6c.conf
#
# See dhcp6c.conf(5) man page for details.
#
#interface eth0 {
# #information-only;
# send rapid-commit;
# request prefix-delegation;
# #request temp-address;
#};
~文件恢复成功,然后将他拷贝到删除文件的目录下就可以了
