2. Installation Services

[Email protected] Desktop]# yum-y install VSFTPD

Installing:vsftpd-2.2.2-11.el6_4.1.x86_64 1/1

Verifying:vsftpd-2.2.2-11.el6_4.1.x86_64 1/1

Installed:vsftpd.x86_64 0:2.2.2-11.el6_4.1

complete!

3. turn on the service

[[Email protected] Desktop]# service Vsftpdstart

Start vsftpd for vsftpd: [OK]

4. FTP configuration file

1) Main configuration file:/etc/vsftpd/vsftpd.conf

2) blacklist file:/etc/vsftpd/ftpusers

3) Black/White list file:/etc/vsftpd/user_list

Step Two: Client testing

1. Create a test file, create a file/var/ftp/ftptest.txt/home/lisi/lisi.txt

[email protected] ftp]# Touch ftptest.txt

[Email protected] ftp]# Touch/home/lisi/lisi.txt

3. Linux Client Authentication

[[Email protected] Desktop]# FTP 192.168.4.5//Login FTP

Connected to 192.168.4.5 (192.168.4.5).

Name (192.168.4.5:root): FTP//Enter the default anonymous user

331 Specify the password.

Password://any password

Successful Login. Login successful

ftp> pwd

257 "/"//The root directory path for anonymous users is/var/ftp

Master configuration file (vsftpd.conf) parsing:

Anonymous_enable=yes//(default) Allow Anonymous Logon

Local_enable=yes//Allow local users to log in

Anon_upload_enable=yes//Allow anonymous uploading of files

Anon_mkdir_write_enable=yes//Allow anonymous creation of directories

Anon_other_write_enable=yes//Allow other write permissions

Write_enable=yes//(default) Allow Write (global)

anon_umask=022//Set upload file permission mask

Chroot_local_user=yes//Imprison local user home directory

Userlist_enable=yes//(default) Enable User_list list file

Userlist_deny=no//User_list as Whitelist

MAX_CLIENTS=20//maximum number of concurrent connections allowed

max_per_ip=2//Per IP address maximum number of connections allowed

anon_max_rate=50000//Anonymous download speed, byte/s

local_max_rate=200000//local user download speed, byte/s

ftpusers blacklist--- à userlist_enable=yes/no This parameter determines whether the blacklist is valid

user_list-- à userlist_deny=yes/no "Yes" is blacklisted as "NO" as the whitelist

Step Three: Troubleshooting

The following error occurred while entering the FTP command on the Linux customer service side

[[Email protected] Desktop]# FTP 192.168.4.5

Bash:ftp:command not found

Cause: The client does not have an FTP program installed

[[Email protected] Desktop]# yum-y install FTP

Description

When you log on as an anonymous user, the root directory is in the/var/ftp directory, and the root directory is in the user's home directory when you log on as a local user
