proFTPD as non-root user

1

I am trying tp set up the FTP into our local galaxy instance, as a non -root user. I follow the tuto from this link https://docs.galaxyproject.org/en/latest/admin/special_topics/ftp.html. Is it possible to run the galaxy instance without root ?

With this conf file :

# Basics, some site-specific
ServerName			"Public Galaxy FTP"
ServerType			standalone
DefaultServer			on
Port				20021
Umask				077
SyslogFacility			DAEMON
SyslogLevel			debug
MaxInstances			30

# This User & Group should be set to the actual user and group name which matche the UID & GID you will specify later in the SQLNamedQuery.
User				nobody
Group				nobody
DisplayConnect			/etc/opt/local/proftpd_welcome.txt

# Passive port range for the firewall
PassivePorts			30000 40000

# Cause every FTP user to be "jailed" (chrooted) into their home directory
DefaultRoot			~

# Automatically create home directory if it doesn't exist
CreateHome			on dirmode 700

# Allow users to overwrite their files
AllowOverwrite			on

# Allow users to resume interrupted uploads
AllowStoreRestart		on

# Bar use of SITE CHMOD
<Limit SITE_CHMOD>
    DenyAll
</Limit>

# Bar use of RETR (download) since this is not a public file drop
<Limit RETR>
    DenyAll
</Limit>

# Do not authenticate against real (system) users
<IfModule mod_auth_pam.c>
AuthPAM				off
</IfModule>

# General database support (http://www.proftpd.org/docs/contrib/mod_sql.html)
#SQL module
LoadModule mod_sql.c

# Support for base-64 or hex encoded MD5 and SHA1 passwords from SQL tables
# (contrib/mod_sql_passwd.html)
LoadModule mod_sql_passwd.c

# Common SQL authentication options
SQLEngine			on
SQLPasswordEngine		on
SQLBackend			postgres
SQLConnectInfo			postgres@localhost:5432 galaxyftp <password>
SQLAuthenticate			users

# For PBKDF2 authentication
# See http://dev.list.galaxyproject.org/ProFTPD-integration-with-Galaxy-td4660295.html
SQLPasswordUserSalt		sql:/GetUserSalt

# Define a custom query for lookup that returns a passwd-like entry for PBKFD2
#  UID and GID should match your Galaxy user.
SQLUserInfo			custom:/LookupGalaxyUser
SQLNamedQuery			LookupGalaxyUser SELECT "email, (CASE WHEN substring(password from 1 for 6) = 'PBKDF2' THEN substring(password from 38 for 69) ELSE password END) AS password2,400,400,'/opt/galaxy/ftp_uploads/%U','/bin/bash' FROM galaxy_user WHERE email='%U'"

# Define custom query to fetch the password salt
SQLNamedQuery			GetUserSalt SELECT "(CASE WHEN SUBSTRING (password from 1 for 6) = 'PBKDF2' THEN SUBSTRING (password from 21 for 16) END) AS salt FROM galaxy_user WHERE email='%U'"

I have the following problem of permissions :

  [galaxy@node01 ~]$ proftpd --config /media/vol2/home/galaxy/proftpd.conf -t
