Installation and configuration of VSFTPD under Linux

1. Installation

Execute yum-y Install vsftpd

Note: (1) You can check whether the VSFTPD is installed by Rpm-qa|grep vsftpd .

(2) The default configuration file is/etc/vsftpd/vsftpd.conf

2. Create a virtual user for the VSFTPD server

(1) Select Create FTP folder in root directory or user directory:mkdir ftpfile

I started by entering the root directory to create the folder product and then into product to create the Ftpfile folder.

CD/mkdir PRODUCTCD productmkdir ftpfile

·

(2) Add anonymous User: Useradd ftpuser-d/ftpfile-s/sbin/nologin

Execute command

/product/ftpfile -s/sbin/nologin

/product/ftpfile is an FTP folder.

Because a folder is created first, a duplicate warning appears for the directory name.

(3) Modify Ftpfile permissions: Chown-r ftpuser.ftpuser/ftpfile

Execute chown-r ftpuser.ftpuser./ftpfile

(4) Reset ftpuser password: passwd ftpuser

Execute passwd ftpuser , then access the new password two times.

3. Configuration

Perform

cd/etc/Vsftpdvim chroot_list

Add the FTP username : Wq save to exit.

Vim/etc.selinux/config

Modify to Selinux=disabled

Perform vim vsftpd.conf Edit as
