Linux to build our school FTP service

1. Create user teacher and specify their home directory as/ftproot, password set to [email protected] (5 points)

[Email protected] ~]# useradd-d/ftproot teacher

[Email protected] ~]# echo [email protected] |passwd--stdin teacher

[[email protected] ~]# grep teacher/etc/passwd

To create its home directory:

650) this.width=650; "title=" clip_image002 "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; margin:0px; padding-right:0px "border=" 0 "alt=" clip_image002 "src=" http://s3.51cto.com/wyfs02/M02/86/6A/ Wkiom1e-ydtzxelfaaaosczztka791.jpg "" 244 "height="/>

Create users and make their home directories:

650) this.width=650; "title=" clip_image004 "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; margin:0px; padding-right:0px "border=" 0 "alt=" clip_image004 "src=" http://s3.51cto.com/wyfs02/M01/86/6A/ Wkiol1e-ydxtr19vaaaov0tdyxa260.jpg "" 244 "height="/>

Set Password:

650) this.width=650; "title=" clip_image006 "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; margin:0px; padding-right:0px "border=" 0 "alt=" clip_image006 "src=" http://s3.51cto.com/wyfs02/M01/86/6A/ Wkiom1e-ydwjv7c6aaasz7garaq185.jpg "" 244 "height="/>

To view user information:

650) this.width=650; "title=" clip_image008 "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; margin:0px; padding-right:0px "border=" 0 "alt=" clip_image008 "src=" http://s3.51cto.com/wyfs02/M01/86/6A/ Wkiol1e-ydaazmgaaaaumpadqtc765.jpg "" 244 "height="/>

2. Use/dev/sd{b,c,d} to create a logical volume with size 45G/dev/ftp_vg/ftp_lv and mount it permanently to the/ftproot directory. (30 points)

[Email protected] ~]# Fdisk-cu/dev/sdb

[Email protected] ~]# FDISK-CU/DEV/SDC

[Email protected] ~]# FDISK-CU/DEV/SDD

[Email protected] ~]# pvcreate/dev/sd{b,c,d}1

[Email protected] ~]# vgcreate/dev/ftp_vg/dev/sd{b,c,d}1

[Email protected] ~]# lvcreate-n/dev/ftp_vg/ftp_lv-l 45G

[Email protected] ~]# MKFS.EXT4/DEV/FTP_VG/FTP_LV

[Email protected] ~]# Vi/etc/fstab

/dev/ftp_vg/ftp_lv/ftproot EXT4 Defaults 0 0

: Wq

[Email protected] ~]# mount-a

[email protected] ~]# mount

To partition a disk:

650) this.width=650; "title=" clip_image010 "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; margin:0px; padding-right:0px "border=" 0 "alt=" clip_image010 "src=" http://s3.51cto.com/wyfs02/M02/86/6A/ Wkiom1e-ydeihdgyaaavj5jzpe8444.jpg "" 244 "height=" 135 "/>

650) this.width=650; "title=" clip_image012 "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; margin:0px; padding-right:0px "border=" 0 "alt=" clip_image012 "src=" http://s3.51cto.com/wyfs02/M00/86/6A/ Wkiol1e-ydei8xn-aabcruvt0wu162.jpg "" 244 "height=" 154 "/>

T is to set the partition type, L is to view all types, 8e is LVM type, W save

The steps for B,c,d disks are roughly the same

To create a logical Volume:

650) this.width=650; "title=" clip_image014 "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; margin:0px; padding-right:0px "border=" 0 "alt=" clip_image014 "src=" http://s3.51cto.com/wyfs02/M02/86/6A/ Wkiol1e-ydibwykyaaaj2i4tvs8569.jpg "" 244 "height="/>

To create a volume group:

650) this.width=650; "title=" clip_image016 "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; margin:0px; padding-right:0px "border=" 0 "alt=" clip_image016 "src=" http://s3.51cto.com/wyfs02/M00/86/6A/ Wkiom1e-yd-b4z2caaatbaoioo4543.jpg "" 244 "height="/>

To create a logical volume and set the size:

650) this.width=650; "title=" clip_image018 "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; margin:0px; padding-right:0px "border=" 0 "alt=" clip_image018 "src=" http://s3.51cto.com/wyfs02/M00/86/6A/ Wkiom1e-yd-rbkzwaaapcjl1ouw411.jpg "" 244 "height="/>

3. Install and configure the FTP for the school as per the following requirements:

1) There are three directories in the FTP root directory:

Benet5.2 requires all learners to be able to upload a job (upload file cannot be: *.rmvb,*.mp3,*.avi,*.exe) but cannot download, and requires teacher to authorize the directory and download the trainee job; (20 points)

Public requires sharing learning materials, students can download can not upload, teacher can upload and download; (20 points)

The teacher directory is accessible only to teacher and not to anyone else. (20 points)
