Linux FTP build tutorial, linuxftp build tutorial

I. Install the ftp service

Set IP Address

Attach a cd

Disable iptables Firewall

Disable selinux/[root @ localhost ~] # Setenforce 0

[Root @ localhost ~] # Cd/media/cdrom/Packages/

[Root @ localhost Packages] # rpm-ivh vsftpd-2.2.2-11.el6_4.1.x86_64.rpm

Ii. ftp service based on system users

1: anonymous access to the ftp service

1): Create a test file for ftp download.

[Root @ localhost ~] # Tar zcf/var/ftp/vsftpdconf.tar.gz/etc/vsftpd/

[Root @ localhost ~] # Chown ftp/var/ftp/pub/\ pub belongs to anonymous user ftp

2): enable Anonymous user configuration and start vsftpd service

[Root @ localhost ~] # Vi/etc/vsftpd. conf

12 anonymous_enable = YES \ Anonymous Users are allowed

15 local_enable = NO \ do not enable local users

18 write_enable = YES \ write allowed

23 anon_umask = 022 \ add, permission mask for data upload

27 anon_upload_enable = YES \ Allow Anonymous File Upload

31anon_mkdir_write_enable = YES \ Allow anonymous users to create directories

[Root @ localhost ~] # Service vsftpd start

[Root @ localhost ~] # Netstat-anpt | grep "vsftpd"

3): linux client Testing

[Root @ localhost ~] # Cd/media/cdrom/Packages/

[Root @ localhost Packages] # rpm-ivh ftp-0.17-54.el6.x86_64.rpm \ install client Tool

[Root @ localhost Packages] # ftp 192.168.10.10 \ name: use ftp and Password at will

Ftp> ls

Ftp> LCD/opt \ switch the local directory to/opt, and the data downloaded from ftp will be stored in the local/opt directory.

Ftp> get vsftpdconf.tar.gz

Ftp> LCD/root

Ftp> cd pub

Ftp> put install. log

[Root @ localhost ~] # Wget ftp: // 192.168.10.10/vsftpdconf.tar.gz

2: User-verified ftp service

1): Configure Local User Authentication

[Root @ localhost ~] # Vi/etc/vsftpd. conf

15 local_enable = yes

18 write_enable = YES

22 local_umask = 077

96 chroot_local_user = YES

[Root @ localhost ~] # Service vsftpd start

[Root @ localhost ~] # Useradd zhangsan

[Root @ localhost ~] # Passwd zhangsan

[Root @ localhost ~] # Useradd lisi

[Root @ localhost ~] # Passwd lisi

2): client Verification

[Root @ localhost ~] # Ls> uptest.txt

[Root @ localhost ~] # Ftp 192.168.10.10

Log On with the account and password of zhangsan and lisi

Ftp> put uptest.txt \ is uploaded to the/home/zhangsan directory of Michael Jacob.

Ftp> quit

3): Use the user_list user list file

[Root @ localhost ~] # Vi/etc/vsftpd/user_list

Add only zhangsan, and delete all others

Zhangsan

[Root @ localhost ~] # Vi/etc/vsftpd. conf

118 userlist_enable = YES

119 userlist_deny = no \ add

[Root @ localhost ~] # Service vsftpd restart

Use zhangsan and lisi for login verification respectively

3: Other configurations

1): Modify the listening address and port

[Root @ localhost ~] # Vi/etc/vsftpd. conf

110 listen = YES

111listen_address = 192.168.10.10 \ add listening address

112 listen_port = 2121 \ add listening port

[Root @ localhost ~] # Service vsftpd restart

2): client Test

[Root @ localhost ~] # Ftp 192.168.10.10 2121

3): Use the ftp passive mode.

123 pasv_enable = yes

124 pasv_min_port = 24500

125 pasv_max_port = 24600

[Root @ localhost ~] # Service vsftpd restart

Iii. ftp service based on virtual users

1: create an account database for a virtual user

1): create a user name and password list in text format

[Root @ localhost ~] # Vi/etc/vsftpd/vusers. list

Add

Mike

Aptech

Wjq

Aptech

2): create database files in the berkeley DB format

[Root @ localhost ~] # Cd/etc/vsftpd/

[Root @ localhost vsftpd] # db_load-T-t hash-f vusers. list vusers. db

[Root @ localhost vsftpd] # file vusers. db

Vusers. db: Berkeley DB (Hash, version 9, native byte-order)

[Root @ localhost vsftpd] # chmod 600/etc/vsftpd/vusers .*

[Root @ localhost vsftpd] # ls-lh/etc/vsftpd/vusers .*

3): Add a ing account for a virtual user and a common ftp root directory

[Root @ localhost vsftpd] # useradd-d/var/ftproot-s/sbin/nologinvirtual

[Root @ localhost vsftpd] # chmod 755/var/ftproot/

[Root @ localhost vsftpd] #

2: Add virtual user support for the vsftpd service

1): Create a PAM Authentication file for the virtual user

[Root @ localhost vsftpd] # vi/etc/pam. d/vsftpd. vu

Auth required pam_userdb.sodb =/etc/vsftpd/vusers

Account required pam_userdb.so db =/etc/vsftpd/vusers

2): Modify vsftpd and add virtual user support

[Root @ localhost vsftpd] # vi/etc/vsftpd. conf

Delete

112 listen_port = 2121

118 userlist_enable = YES

119 userlist_deny = no

Add

15 local_enable = yes

18 write_enable = YES

23anon_umask = 022

118pam_service_name = vsftpd. vu \ add

120 guest_enable = yes \ add

121 guest_username = virtual \ add

3): create independent configuration files for different virtual users

[Root @ localhost vsftpd] # vi/etc/vsftpd. conf

122user_config_dir =/etc/vsftpd/vusers_dir \ add

[Root @ localhost vsftpd] # mkdir/etc/vsftpd/vusers_dir/

[Root @ localhost vsftpd] # cd/etc/vsftpd/vusers_dir/

[Root @ localhost vusers_dir] # vi mike

Add

Anon_upload_enable = yes

Anon_mkdir_write_enable = yes

[Root @ localhost vusers_dir] # touch wjq

[Root @ localhost vusers_dir] # service vsftpd restart

4): use both mike and wjq for Logon verification.
