I would like to perform the equivalent in linux of sudo /etc/init.d/vsftpd restart
To use chroot, vsftpd requires root privileges, so you will need to run sudo vsftpd. You should be certain that you trust any software you grant root privileges.
The vsftpd.conf file must be owned by root or vsftpd will refuse to start: sudo chown root /usr/local/etc/vsftpd.conf
To have launchd start vsftpd now and restart at startup: sudo brew services start vsftpd Or, if you don't want/need a background service you can just run: sudo vsftpd
So your vsftpd.conf file is in /usr/local/etc.
