Installation and configuration of Linux FTP

For the ftp installation part, the operation steps are as follows:

You can use the yum command to directly install ftp

# yum install vsftpd

ftp service enable and disable command:

enable: # service vsftpd start

disable: # service vsftpd stop

After the installation is successful, you can use the ftp software to connect locally , the default account is the account and password of the virtual machine.

Add the ftp user in linux and set the corresponding permissions. The operation steps are as follows:

1. Environment:

ftp is vsftp and the restricted user name is test. The restricted path is /home/test

2. Create a user: under the root user:

# useradd -d /home/test test //Add user test, and make the test user's home directory as /home/test
# passwd test // Set a password for test
3. Change the user's corresponding permission settings:

# usermod -s /sbin/nologin test //Limited user test cannot telnet, only ftp
# usermod -s /sbin/bash test //User test returns to normal
# usermod -d /test test //Change the home directory of user test to /test
4. Restrict users to access only /home/test and not other paths:

Modify # /etc/vsftpd/vsftpd.conf as follows:

chroot_list_enable=YES //Restrict access to its own directory

# (default follows)

chroot_list_file=/etc/vsftpd/vsftpd.chroot_list

Edit the vsftpd.chroot_list file and add the restricted users, one line per user name After

changing the configuration file, don't forget Restart the vsFTPd server.

# /etc/init.d/vsftpd restart

5. If you need to allow the user to change the password, but do not have the right to log in to the system by telnet:

# usermod -s /usr/bin/passwd test //Users will directly enter the password change interface after telnet
