《OD学hadoop》第一周0626 作业二:Linux基础

一、打包压缩

知识点:

tar -zxvf -C PATH

tar -jxvf

tar -zcvf

tar -jcvf

tar:打包命令

-z 打包同时gzip压缩

-j 打包同时bzip2

-c 打包

-x 解压

-v 显示过程信息

-f 对普通文件进行操作

-C 指定解压路径

-t 查看包内容

(1)tar -zcvf `date +"%Y_%m_%d"`etc.tar.gz /etc

(2)tar -zxvf 2016_07_01etc.tar.gz -C /tmp

(3)tar -tvf 2016_07_01etc.tar.gz

二、磁盘分区

(1)

[root@beifeng-hadoop- temp]# fdisk -l

Disk /dev/sda: 21.5 GB,  bytes
heads, sectors/track, cylinders
Units = cylinders of * = bytes
Sector size (logical/physical): bytes / bytes
I/O size (minimum/optimal): bytes / bytes
Disk identifier: 0x000adb00 Device Boot Start End Blocks Id System
/dev/sda1 * Linux
Partition does not end on cylinder boundary.
/dev/sda2 Linux
/dev/sda3 Linux swap / Solaris
[root@beifeng-hadoop- temp]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 16G .7G 11G % /
tmpfs 491M 232K 491M % /dev/shm
/dev/sda1 194M 29M 156M % /boot
/dev/sr0 .1G .1G % /media/CentOS_6.4_Final

fdisk /dev/sdc

[root@beifeng-hadoop-01 /]# mkdir -p /data/primary
[root@beifeng-hadoop-01 /]# mkdir -p /data/logic
[root@beifeng-hadoop-01 /]# chown -R 777 /data/primary/
[root@beifeng-hadoop-01 /]# chown -R 777 /data/logic/

(2)

mkfs.ext4 /dev/sdc1

mount /dev/sdc1 /data/primary/

df -h

lost+found 用于磁盘恢复,一般没什么用

(3)

fdisk /dev/sdc

sdc1 sdc2 sdc3 sdc4

sdc5

mkfs.ext3 /dev/sdc5

6.0 以前 partprobe /dev/sdc5 平滑刷新整个分区结构

partx -a /dev/sdc5

重启后格式化

mkfs.ext3 /dev/sdc5

mount /dev/sdc5 /data/logic/

vim /etc/fstab

:x 保存退出

(4)

vi /etc/fstab

/dev/sdc1 /data/ primary ext4 dafaults 0  0

三、RPM包

(1)

[root@beifeng-hadoop- /]# whereis touch
touch: /bin/touch /usr/share/man/man1p/touch.1p.gz /usr/share/man/man1/touch..gz
[root@beifeng-hadoop- /]# rpm -qf /bin/touch
coreutils-8.4-.el6.x86_64

(2)

rpm -qa

[root@beifeng-hadoop- /]# rpm -qa | grep bind
bind-9.8.-0.17.rc1.el6.x86_64
bind-utils-9.8.-0.17.rc1.el6.x86_64
ypbind-1.20.-.el6.x86_64

bind-libs-9.8.-0.17.rc1.el6.x86_64
PackageKit-device-rebind-0.5.-.el6.x86_64

(3)

[root@beifeng-hadoop- Packages]# pwd
/media/CentOS_6.4_Final/Packages
[root@beifeng-hadoop- Packages]# ll | grep bind
-r--r--r--. beifeng beifeng Feb bind-9.8.-0.17.rc1.el6.x86_64.rpm

-r--r--r--. beifeng beifeng Feb ypbind-1.20.-.el6.x86_64.rpm
rpm -ivh bind-9.8.-0.17.rc1.el6.x86_64.rpm

(4)

rpm -ql bind

四、yum命令

安装软件3种方式

rpm/yum/make install

(1)

yum list installed 

(2)

[root@beifeng-hadoop- Packages]# yum list installed | grep httpd-devel
httpd-devel.x86_64 2.2.-.el6.centos

(3)

yum install httpd-devel

(4)

(5)

五、Shell编程

1.

2.

3.

touch -d "20 days ago " /backup/abc.log

4. crontab

/: 每

,: 分别,枚举
