anonymous_enable=NO        //禁用匿名用户
chroot_local_user=YES    //打开注释，禁止切换根目录

Others:
chroot_list_enable=YES
chroot_list_file=/etc/vsftpd/chroot_list

chroot_local_user=YES
chroot_list_enable=YES
hroot_list_file=/etc /vsftpd/chroot_list
Do not prohibit users in the /etc/vsftpd/chroot_list directory

Define the maximum transfer rate for anonymous users, in bytes:
anon_max_rate=10240
Limit the maximum transmission rate for local users The download speed is 10KB/s
local_max_rate=10240
The number of connections is limited:
max_clients=100
max_per_ip=2

4. Test connection

You can use ftp ip to test the connection.

It may happen that after logging in,

500 OOPS: chroot

needs to close selinux:

(1) Use setenforce 0 to temporarily close

(2) Or modify the configuration file

Modify the /etc/selinux/config file

Change SELINUX=enforcing to SELINUX=disabled

Restart the machine

500 OOPS: vsftpd: refusing to run with writable root inside chroot()

From 2.3 After .5, vsftpd has enhanced security checks. If a user is restricted to his home directory, the user's home directory can no longer have write permissions! If the check finds that there is still write permission, this error will be reported.

(1) Remove the write permission of the user root directory chmod a-w /home/ftpuser/ ftp user root directory

(2) Or modify the vsftpd configuration file to allow write permission

Edit the /etc/vsftpd/vsftpd.conf file and add allow_writeable_chroot=YES

Restart the vsftpd service service vsftpd restart

(If you want to upload, use lftp connection)

Generate a certificate and import it into the ftp service

(You can purchase or generate the certificate yourself for testing)

Edit /etc/vsftpd/vsftpd.conf, import the certificate and restart the ftpd service

ssl_enable=YES
ssl_tlsv1=YES
ssl_sslv2=YES
ssl_sslv3=YES
allow_anon_ssl=NO
force_local_data_ssl=YES
force_local_logins_ssl=YES
rsa_cert_file=/etc/vsftpd/ssl/vsftpd.crt
rsa_private_key_file=/etc/vsftpd/ssl/vsftpd.key

After restarting, you can use FileZilla to test the connection.
