linux文本处理sed、软件包管理、磁盘存储和文件系统

1.取基名和文件名

[[email?protected] scripts38]#echo /etc/sysconfig/network-scripts/ |sed -r ‘[email?protected](^/.*/)([^/]+)/[email?protected][email?protected]‘
/etc/sysconfig/

[[email?protected] scripts38]#echo /etc/sysconfig/network-scripts/ |sed -r ‘[email?protected](^/.*/)([^/]+)/[email?protected][email?protected]‘
network-scripts

2.把网络修改成eth0

[[email?protected] scripts38]#sed -ri ‘/^[[:space:]]+linux16/[email?protected](.*)@& [email?protected]‘ /boot/grub2/grub.cfg 
[[email?protected] data]#sed -ri ‘/GRUB_CMDLINE_LINUX=/[email?protected]"[email?protected] net.ifnames=0"@‘ /etc/default/grub

3.可能需要先下载前面那个包，才可以开启神奇文件夹，可以自动挂载光盘。

[[email?protected] Packages]#[[email?protected] ~]#yum install autofs
[[email?protected] data]#systemctl start autofs
[[email?protected] data]#systemctl enable autofs
Created symlink from /etc/systemd/system/multi-user.target.wants/autofs.service to /usr/lib/systemd/system/autofs.service.
[[email?protected] data]#cd /misc
[[email?protected] misc]#cd cd/

4.导入RPM验钞机

[[email?protected] scripts38]#ls /misc/cd/
CentOS_BuildTag  images    repodata
EFI              isolinux  RPM-GPG-KEY-CentOS-7
EULA             LiveOS    RPM-GPG-KEY-CentOS-Testing-7
GPL              Packages  TRANS.TBL
[[email?protected] scripts38]#rpm --import /misc/cd/RPM-GPG-KEY-CentOS-7

4.本地和阿里YUM源配置。清除缓存yum clean all

[base]
name=cdrom base
baseurl=file:///misc/cd
gpgcheck=1
gpgkey=file:///misc/cd/RPM-GPG-KEY-CentOS-7 

[epel]
name=aliyun epel
baseurl=https://mirrors.aliyun.com/epel/$releasever/$basearch/
gpgcheck=0
enabled=0     #开启epel换为1

配置阿里云repo源，注意工作目录。

[[email?protected] data]#wget http://mirrors.aliyun.com/repo/Centos-7.repo
[[email?protected] /]#mv Centos-7.repo /etc/yum.repos.d/

5.搭建网络YUM源

[[email?protected] data]#yum install httpd
[[email?protected] data]#systemctl start httpd
[[email?protected] data]#cd /var/www/html
[[email?protected] html]#mkdir -pv  centos/{6,7}/os/x86_64/
[[email?protected] html]#mount /dev/sr0 centos/7/os/x86_64/
mount: /dev/sr0 is write-protected,mounting read-only
[[email?protected] html]#mount /dev/sr1 centos/6/os/x86_64/
mount: /dev/sr1 is write-protected,mounting read-only

6.删除centos7系统/etc/grub2.cfg文件中所有以空白开头的行行首的空白字符

[[email?protected] ~]#sed -r ‘s/^[[:space:]]([[:space:]]+.*)/1/‘ /etc/grub2.cfg

7.删除/etc/fstab文件中所有以#开头，后面至少跟一个空白字符的行的行首的#和空白字符

[[email?protected] yum.repos.d]#sed -r ‘s/^#[[:space:]]+//‘ /etc/fstab

8.在centos6系统/root/install.log每一行行首增加#号

[[email?protected] ~]#sed -r ‘s/(.*)/#1/‘ /root/install.log

9.处理/etc/fstab路径,使用sed命令取出其目录名和基名

[[email?protected] ~]#echo /etc/fstab | sed -r ‘[email?protected](^/.*/)([^/]+)/[email?protected][email?protected]‘
/etc/
[[email?protected] ~]#echo /etc/fstab | sed -r ‘[email?protected](^/.*/)([^/]+)/[email?protected][email?protected]‘
fstab

10.利用sed 取出ifconfig命令中本机的IPv4地址

[[email?protected] ~]#ifconfig eth0 | sed -rn ‘2s/^[^0-9]+([0-9.]+).*/1/p‘
172.18.145.136

11.统计centos安装光盘中Package目录下的所有rpm文件的以.分隔倒数第二个字段的重复次数

[[email?protected] Packages]#ls /misc/cd/Packages/ |sed -rn ‘[email?protected]*.(.*)..*@[email?protected]‘|sort|uniq -c|sort -nr
   4639 x86_64
   3122 noarch
   2258 i686

SNART不知道是这么来的。。。

[[email?protected] Packages]#ls /misc/cd/Packages/ |rev|cut -d ‘.‘ -f2 |sort |uniq -c |sort -nr
   4639 46_68x
   3122 hcraon
   2258 686i
      1 SNART

12.统计/etc/init.d/functions文件中每个单词的出现次数，并排序（用grep和sed两种方法分别实现）

这个感觉应该是没毛病

[[email?protected] Packages]#cat /etc/init.d/functions |egrep -o "&;[[:alpha:]]+&;" |sort |uniq -c|sort -nr
     60 if
     54 return
     52 then
     51 fi
     49 echo
     46 pid
     38 n

这个好像也不准，sed还是没有取单词的功能的

[[email?protected] Packages]#cat /etc/init.d/functions |sed -r ‘[email?protected][^[:alpha:]][email?protected][email?protected]‘|sort|uniq -c|sort -nr|head
   1047 
     73 pid
     60 if
     58 file
     57 echo
     54 return
     52 then
     51 fi
     39 n
     38 base

这个应该是错误的。。。

[[email?protected] Packages]#cat /etc/init.d/functions |sed -r ‘[email?protected][[:space:]][email?protected][email?protected]‘|sort|uniq -c|sort -nr|head
    608 
    103 [
     66 #
     64 ]
     59 &&
     58 if
     54 return
     52 then
     51 fi
     43 echo

13.将文本文件的n和n+1行合并为一行，n为奇数行

[[email?protected] Packages]#seq 10 |xargs -n2
1 2
3 4
5 6
7 8
9 10

sed高级用法太变态，头发容易秃，玩不了玩不了

[[email?protected] Packages]#seq 10|sed ‘N;s/n/ /‘
1 2
3 4
5 6
7 8
9 10

14.自己配一些yum仓库

[[email?protected] data]#mkdir dnf
[[email?protected] data]#cd dnf/
[[email?protected] dnf]#rz -E
rz waiting to receive.
[[email?protected] dnf]#ll
total 808
-rw-r--r-- 1 root root 213696 Jun  4  2018 dnf-0.6.4-2.sdl7.noarch.rpm

自己配置repo
[[email?protected] yum.repos.d]#cat dnf.repo 
[dnf]
name=dnf
baseurl=file:///data/dnf
gpgcheck=0
查看是否成功
[[email?protected] yum.repos.d]#yum repolist

后面编脚本了

tar -xvf httpd-2.4.25.tar.bz2
cd httpd-2.4.25/
指定路径，配置文件所在位置，开启一些服务，报错，缺APR
[[email?protected] httpd-2.4.25]#./configure  --prefix=/apps/httpd24 --sysconfdir=/etc/httpd --enable-ssl --enable-so

下载APR包
[[email?protected] httpd-2.4.25]#yum install apr-devel
缺少什么包补什么包
[[email?protected] httpd-2.4.25]#yum install apr-util-devel
[[email?protected] httpd-2.4.25]#yum install pcre-devel
错误，不是这个包[[email?protected] httpd-2.4.25]#yum install mod_ssl
[[email?protected] httpd-2.4.25]#yum install openssl-devel
还有前面装了个gcc
成功后，执行make编译
然后再make install
[[email?protected] httpd-2.4.25]#make
[[email?protected] httpd-2.4.25]#make install
完成后
[[email?protected] httpd24]#cd /apps/httpd24/
写到环境变量中
[[email?protected] httpd24]#vim /etc/profile.d/env.sh
PATH=/apps/httpd24/bin:/apps/tree/bin:$PATH 
重读，刷新环境变量
[[email?protected] httpd24]#. /etc/profile.d/env.sh
开启服务
[[email?protected] httpd24]#apachectl restart
自动启动的文件，要把路径写里去
[[email?protected] httpd24]#ll /etc/rc.d/rc.local
-rw-r--r--. 1 root root 473 Oct 31  2018 /etc/rc.d/rc.local
[[email?protected] httpd24]#vim /etc/rc.d/rc.local
把下面的写到里面
/apps/httpd24/bin/apachectl start 
然后给这个文件执行权限。
[[email?protected] httpd24]#chmod +x /etc/rc.d/rc.local
页面显示的地方，可以自己修改。
[[email?protected] httpd24]#cd htdocs/
[[email?protected] htdocs]#ll
total 4
-rw-r--r-- 1 root root 45 Jun 12  2007 index.html

15.编译一个小东西

[[email?protected] data]#tar -xvf cmatrix-1.2a.tar.gz 
[[email?protected] cmatrix]#yum install ncurses-devel
[[email?protected] cmatrix]#./configure --prefix=/apps/cmatrix
[[email?protected] cmatrix]#make
[[email?protected] cmatrix]#make install

16.mbr分区表的备份和还原

查看MBR分区表前512个字节
[[email?protected] data]#hexdump -C /dev/sda -n 512
把分区表的64个字节拷贝出来，skip是跳过原文件的446个字节。
[[email?protected] data]#dd if=/dev/sda of=/data/mar_db bs=1 count=64 skip=446
64+0 records in
64+0 records out
64 bytes (64 B) copied,0.000585693 s,109 kB/s
把数据拷贝到其他服务器上
[[email?protected] data]#scp mar_db [email?protected]:/data
破坏原来的分区表，seek是跳过目标的446个字节。服务器无法启动。
[[email?protected] data]#dd if=/dev/zero of=/dev/sda bs=1 count=64 seek=446
重启进入救援模式。临时配一个IP地址
[[email?protected] ~]#ifconfig ens33 172.18.145.164
把备份的拷回来
[[email?protected] ~]#scp [email?protected]:/data/mar_db .
[[email?protected] data]#dd if=mar_db of=/dev/sda bs=1 count=64 skip=446
重启电脑
exit

MBR分区
按柱面

最多4个分区，3个主分区，一个扩展分区，扩展分区中可以有多个逻辑分区。

最多管理2T的空间

GPT分区

按扇区

128个分区

最多管理8Z的空间

128位UUID

分区表有备份功能

17.parted命令

parted的操作都是实时生效的，小心使用
用法：parted [选项]... [设备 [命令 [参数]...]...]
parted /dev/sdb mklabel gpt|msdos
parted /dev/sdb print
parted /dev/sdb mkpart primary 1 200 （默认M）
parted /dev/sdb rm 1
parted  /dev/sdb –l 列出分区信息

18.模拟文件系统出故障

破坏
[[email?protected] data]#dd if=/dev/zero of=/dev/sda5 bs=1M count=1
已经被破坏，超级块打不开了
[[email?protected] data]#tune2fs -l /dev/sda5
tune2fs 1.42.9 (28-Dec-2013)
tune2fs: Bad magic number in super-block while trying to open /dev/sda5
Couldn‘t find valid filesystem superblock.
先取消挂载。必须在取消挂载的情况下修复
[[email?protected] ~]#umount /data
文件系统故障。无法挂载
[[email?protected] ~]#mount /dev/sda5 /data/
mount: mount /dev/sda5 on /data failed: Structure needs cleaning
xfs系统的修复方法
[[email?protected] data]#xfs_repair /dev/sda5
centos6 ext系列的修复方法
fsck /dev/sda5 -y
修复完成可以挂载
[[email?protected] ~]#mount /dev/sda5 /data/
[[email?protected] ~]#cd /data/
数据丢失
[[email?protected] data]#ll
total 12
drwxr-xr-x 246 root root 8192 Aug  8 16:34 lost+found

19.增加swap分区，过程没写。文件不能用UUID，不然重启会丢，要写文件名。

[[email?protected] ~]#swapon -s
Filename                Type        Size    Used    Priority
/dev/sdb1                               partition   4194300 0   -1
/dev/sda3                               partition   2097148 0   -2
/swapfile                               file    2097148 0   -3

20.文件挂载文件

创建一个大文件
[[email?protected] ~]#dd if=/dev/zero of=/bigfile bs=1M count=1024 
格式化EXT4
[[email?protected] ~]#mkfs.ext4 /bigfile
mke2fs 1.42.9 (28-Dec-2013)
/bigfile is not a block special device.
Proceed anyway? (y,n) y
Discarding device blocks: done

    32768,98304,163840,229376

Allocating group tables: done                            
Writing inode tables: done                            
Creating journal (8192 blocks): done
Writing superblocks and filesystem accounting information: done
查看格式信息
[[email?protected] ~]#blkid /bigfile
/bigfile: UUID="9e1393ae-8e18-4dee-af73-4fafa373ff29" TYPE="ext4" 
写入文件永久挂载

21.迁移/home数据到一个新的地方，在维护状态。也就是单用户模式。init 1

[[email?protected] data]#mkfs.xfs /dev/sdb2
[[email?protected] data]#mkdir /mnt/home
[[email?protected] data]#mount /dev/sdb2 /mnt/home/
[[email?protected] data]#cp -av /home/. /mnt/home/
[[email?protected] data]#vim /etc/fstab 
UUID=63b5335d-a455-45a8-8f3f-3ebf66fb240a   /home              xfs      defaults    0  0 
[[email?protected] data]#mount -a
数据保留一段时间，没问题，取消挂载，准备删除原来的数据
[[email?protected] data]#umount /home/
现在看到的是原来/home的数据，挂载的时候是被覆盖的，看不到的
[[email?protected] data]#ls /home
zhang
把原来的数据都删除了，一定要注意不要把文件夹删除
[[email?protected] data]#rm -rf /home/*
重新挂载一下，数据就都迁移到新的硬盘。
[[email?protected] data]#mount -a
[[email?protected] data]#df
/dev/sdb2        2086912   33052   2053860   2% /home

22.创建一个2G的文件系统，块大小为2048byte，预留1%可用空间,文件系统ext4，卷标为TEST，要求此分区开机后自动挂载至/test目录，且默认有acl挂载选项

[[email?protected]7 data]#fdisk /dev/sdb
[[email?protected] data]#mke2fs -t ext4 -b 2048 -L ‘TEST‘ -m 1 /dev/sdb5
mke2fs 1.42.9 (28-Dec-2013)
Filesystem label=TEST
OS type: Linux
Block size=2048 (log=1)
Fragment size=2048 (log=1)
Stride=0 blocks,Stripe width=0 blocks
131072 inodes,1048576 blocks
10485 blocks (1.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=269484032
64 block groups
16384 blocks per group,16384 fragments per group
2048 inodes per group
Superblock backups stored on blocks: 
    16384,49152,81920,114688,147456,409600,442368,802816

Allocating group tables: done                            
Writing inode tables: done                            
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done 
[[email?protected] data]#vim /etc/fstab
UUID=e02a9d53-6f8a-4dca-a130-5296fe24975b  /mnt/sdb5              ext4     acl            0 0
[[email?protected] data]#mount -a

23.写?个脚本，完成如下功能：(1) 列出当前系统识别到的所有磁盘设备(2) 如磁盘数量为1，则显?其空间使?信息。否则，则显?最后?个磁盘上的空间使?信息。

#颜色配置
COLOR="33[1;$[RANDOM%7+31]m"                                                             
COLOREND=‘33[0m‘

df |grep /dev/sd | tr -s ‘ ‘|cut -d ‘ ‘ -f1

echo -e "${COLOR}磁盘设备检查完毕 $COLOREND"

NUM=`df |grep /dev/sd |wc -l`
[ "$NUM" -eq 1 ] && echo -e "磁盘的利用率： ${COLOR}`df |grep /dev/sd | tr -s ‘ ‘|cut -d ‘ ‘ -f5` $COLOREND"
[ "$NUM" -gt 1 ] && echo -e "最后一个磁盘的利用率： ${COLOR}`df |grep /dev/sd | tr -s ‘ ‘|cut -d ‘ ‘ -f5|tail -n 1` $COLOREND"

[[email?protected] data]#bash  aaa.sh 
/dev/sda2
/dev/sda5
/dev/sda1
/dev/sdb5
磁盘设备检查完毕 
最后一个磁盘的利用率： 1%

24.简述linux下常?的?件系统有哪些，他们有什么区别？

1. EXT3 
（1）最多只能支持32TB的文件系统和2TB的文件，实际只能容纳2TB的文件系统和16GB的文件
（2）Ext3目前只支持32000个子目录
（3）Ext3文件系统使用32位空间记录块数量和i-节点数量
（4）当数据写入到Ext3文件系统中时，Ext3的数据块分配器每次只能分配一个4KB的块
2. EXT4 
EXT4是Linux系统下的日志文件系统，是EXT3文件系统的后继版本。
（1）Ext4的文件系统容量达到1EB，而文件容量则达到16TB 
（2）理论上支持无限数量的子目录
（3）Ext4文件系统使用64位空间记录块数量和i-节点数量
（4）Ext4的多块分配器支持一次调用分配多个数据块
3. XFS 
（1）根据所记录的日志在很短的时间内迅速恢复磁盘文件内容
（2）采用优化算法，日志记录对整体文件操作影响非常小
（3） 是一个全64-bit的文件系统，它可以支持上百万T字节的存储空间
（4）能以接近裸设备I/O的性能存储数据

25.个人配置简陋般脚本。
