Vsftpd refusing to run with writable root inside chroot error

A few days before the installation of the article installed VSFTPD friend if the login after the installation of refusing to run with writable root inside chroot error,

This is caused by the following update:

-Add stronger checks for the configuration error of running with a writeable
root directory inside a chroot (). This could bite people who carelessly turned
On Chroot_local_user but such are life.

The problem is that the user's root directory is writable and the chroot limit is used, which is not allowed in recent updates. To fix this error, you can use the command chmod a-w/home/user to remove the user's root write permissions, and pay attention to replacing the directory with your own.

Or you can add one of the following two items to the VSFTPD configuration file:

For the standard VSFTPD build (VSFTPD):

Allow_writeable_chroot=yes

For the extended vsftpd build (Vsftpd-ext):

Allow_writable_chroot=yes
