Set up school ftp service
1. Create the user teacher and specify the home directory as / ftproot and the password set to pwd@123 (5 points)
[root@localhost] # useradd-d / ftproot teacher
[root@localhost ~] # echo pwd@123 | passwd-- stdin teacher
[root@localhost ~] # grep teacher / etc/passwd
two。 Create a logical volume / dev/ftp_vg/ftp_lv with a size of 45G using / dev/sd {bforce c ftproot d} and mount it permanently to the / volume directory. (30 points)
[root@localhost ~] # fdisk-cu / dev/sdb
[root@localhost ~] # fdisk-cu / dev/sdc
[root@localhost ~] # fdisk-cu / dev/sdd
[root@localhost ~] # pvcreate / dev/sd {bpene cpene d} 1
[root@localhost ~] # vgcreate / dev/ftp_vg / dev/sd {brecronomec d} 1
[root@localhost] # lvcreate-n / dev/ftp_vg/ftp_lv-L 45G
[root@localhost ~] # mkfs.ext4 / dev/ftp_vg/ftp_lv
[root@localhost ~] # vi / etc/fstab
:
/ dev/ftp_vg/ftp_lv / ftproot ext4 defaults 0 0
: wq
[root@localhost] # mount-a
[root@localhost ~] # mount
3. Install and configure ftp for the school according to the following requirements:
1) there are three directories under the ftp root directory:
Benet5.2 requires all students to upload assignments (upload files cannot be: * .rmvb,*.mp3,*.avi,*.exe) but cannot be downloaded, and teacher is required to authorize and download student assignments to the directory; (20 points)
Public requires sharing of 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)
2) access the test and verify it. (5 points)
Configuration items added by the main profile:
Anon_upload_enable=YES
Anon_mkdir_write_enable=NO
Chown_uploads=YES
Chown_username=teacher
Chroot_local_user=YES
Anon_root=/ftproot
Deny_file= {* .rmvb,*.mp3,*.avi,*.exe}
Recommended steps:
[root@localhost ~] # yum-y install vsftpd
[root@localhost ~] # vi / etc/vsftpd/vsftpd.conf
:% g / ^ # / d (delete comments)
:% g / ^ $/ d (delete blank lines)
Add the following:
Anon_upload_enable=YES
Anon_mkdir_write_enable=NO
Chown_uploads=YES
Chown_username=teacher
Chroot_local_user=YES
Anon_root=/ftproot
Deny_file= {* .rmvb,*.mp3,*.avi,*.exe}
: wq
[root@localhost ~] # chown teacher:teacher / ftproot/
[root@localhost ~] # rm-rf / ftproot/*
[root@localhost ~] # chmod 755 / ftproot/
[root@localhost ~] # / etc/init.d/vsftpd start
[root@localhost ~] # chkconfig vsftpd on
Windows accesses ftp, uses teacher users to log in and create Benet5.2, Public, Teacher directories, establishes class directories and authorizes them under Benet5.2, uploads resources to Public and Teacher directories, and closes the window.
[root@localhost ~] # chmod 700 / ftproot/Teacher/ # # Authorization
Access Test:
Anonymous access, upload jobs, download jobs, download resources in Public, visit teacher.
User teacher login
Permissions to create the teacher folder
Anonymous users do not have permission to access the teacher folder (the above command takes effect)
