How to configure SFTP to /var/www/mydomain.ru site?

Question

SFTP

Given:
VDS with 5 sites.
Task:
give rwX access via SFTP for the user myuser to /var/www/mydomain.ru and prevent it from getting out of this folder.
It was done:
1. a user was created

useradd myuser -g www-data -d /var/www/mydomain.ru -s /bin/false

2. directory created
mkdir /var/www/mydomain.ru
3. folder permissions

chown root:root /var/www
chmod 770 /var/www

4. subfolder rights

chown mouser:www-data /var/www/mydomain.ru
chmod 775 /var/www/mydomain.ru

5. modified in ssh server config:
nano /etc/ssh/sshd_config

Subsystem sftp internal-sftp
Match Group sftp    
    ChrootDirectory %h
    ForceCommand internal-sftp
    AllowTcpForwarding no

6. web server raised mydomain.ru and directory /var/www/mydomain.ru through webmin
7. restarted the corresponding services
service ssh restart && service apache2 graceful
When a user tries to connect via SFTP through Filezilla, it gives an error about the connection being impossible.
In order to check that everything was done correctly, SFTP was configured by the method described above on the / home / username folder, everything worked like clockwork - both writing and reading.
Who met with this and how can it be overcome?

Answer 1

Do not worry, the same proftpd supports working in sftp mode, you can lock the hamster inside with one line in the config. Here is an example setup https://www.digitalocean.com/community/tutorials/h...

Answer 2

Everything is set up, except for the ftp server itself)
