Disable firewall: service iptables stop

Configure vsftpd service

[Root @ vsftpdsvr ~] # Yum install-y vsftpd // install the vsftpd package

[Root @ vsftpdsvr ~] # Mkdir-p/var/ftp/xuhao/sybg // create an ftp directory

Create a user and specify the home directory as the ftp directory

[Root @ vsftpdsvr ~] # Useradd-d/var/ftp/xuhao/-s/sbin/nologin xuhao

[Root @ vsftpdsvr ~] # Useradd-d/var/ftp/xuhao/sybg/-s/sbin/nologin xueyuan

[Root @ vsftpdsvr ~] # Passwd xuhao

[Root @ vsftpdsvr ~] # Passwd xueyuan

Set permissions for the ftp directory/var/ftp/xuhao. The owner is xuhao, the group is xueyuan, and the permission is 735

[Root @ vsftpdsvr ~] # Chown-R xuhao. xueyuan/var/ftp/xuhao/

[Root @ vsftpdsvr ~] # Chmod-R 735/var/ftp/xuhao/

Modify the main configuration file of vsftpd. conf

[Root @ vsftpdsvr ~] # Vim/etc/vsftpd. conf

Anonymous_enable = YES // Allow Anonymous Access

Local_enable = YES // allow local access

Write_enable = YES // write permission allowed

Enable vsftpd

[Root @ vsftpdsvr ~] #/Etc/init. d/vsftpd start

Starting vsftpd for vsftpd: [OK]

Build vsftpd service based on virtual users

Create a virtual user name/Password Database (/etc/vsftpd/vusers. list)

[Root @ vsftpdsvr ~] # Touch/etc/vsftpd/vusers. list

User1

12345

User2

123456

Install the db_load tool to convert it to a DB database file.

[Root @ vsftpdsvr ~] # Yum install-y db4

[Root @ vsftpdsvr ~] # Db_load-T-t hash-f/etc/vsftpd/vusers. list/etc/vsftpd/vusers. db

[Root @ vsftpdsvr ~] # File/etc/vsftpd/vusers. db

/Etc/vsftpd/vusers. db: Berkeley DB (Hash, version 8, native byte-order)

Create the FTP root directory and the system account corresponding to the virtual user

[Root @ vsftpdsvr ~] # Mkdir-p/var/ftp2

[Root @ vsftpdsvr ~] # Useradd-d/var/ftp2/-s/sbin/nologin virtual

[Root @ vsftpdsvr ~] # Chown-R virtual/var/ftp2/

[Root @ vsftpdsvr ~] # Chmod-R 777/var/ftp2 // modify directory permissions

Create a PAM Authentication file (/etc/pam. d/vsftpd. vu)

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

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

Modify the main configuration file of vsftpd. conf and add virtual user support

[Root @ vsftpdsvr ~] # Vim/etc/vsftpd. conf

Anonymous_enable = NO

Local_enable = YES

Pam_service_name = vsftpd. vu

Guest_enable = YES

Guest_username = virtual

User_config_dir =/etc/vsftpd/vusers_dir

Create independent configuration directories and files for users

[Root @ vsftpdsvr ~] # Mkdir/etc/vsftpd/user_dir

[Root @ vsftpdsvr ~] # Vim/etc/vsftpd/user_dir/user1

Anon_upload_enable = YES // upload allowed

Anon_mkdir_write_enable = YES // Folder creation allowed

Anon_other_wirte_enable = YES // allow deletion and rename

[Root @ vsftpdsvr ~] # Touch/etc/vsftpd/user_dir/user2

Restart vsftpd
