How to add/delete FTP users and set permissions in Linux

1. Environment: ftp is vsftp. The username is set to test. The restricted path is /home/test
2. Create a user: Under the root user:

1. useradd -d /home/test test #Add user test and formulate test The user's home directory is/home/test

2. passwd test #Set a password for the test user

3. Change the corresponding permission settings of the user:

1. usermod -s /sbin/nologin test   #限定用户test不能telnet，只能ftp
2. usermod -s /bin/bash test   #用户test恢复正常
3. usermod -d /home/test test      #更改用户test的主目录为/test

4. Restrict users to only access /home/test and not other paths

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

1. chroot_list_enable=YES  #限制访问自身目录
2. 
3. # (default follows)
4. 
5. chroot_list_file=/etc/vsftpd/vsftpd.chroot_list

Edit the vsftpd.chroot_list file and add restricted users, one line for each user name

After changing the configuration file, don’t forget to restart the vsftpd server

1. [root@localhost]# /etc/init.d/vsftpd restart

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

1. usermod -s /usr/bin/passwd test      #用户telnet后将直接进入改密界面

6. If you want to delete the user, use the following code:

1. #在root用户下：
2. userdel -r newuser
3. #在普通用户下：
4. sudo userdel -r newuser

Because the user needs to be completely deleted, So add the -r option to delete the user's home directory and mail directory at the same time.
