1. VSFTPD Overview

Which FTP server is the safest? In UNIX and Linux, VSFTP (Very Secure FTP Daemon, a Very Secure FTP Server) is first introduced ). As the name suggests, the starting point of VSFTPD design is security. At the same time, with the continuous upgrade of the version, VSFTPD has made great progress in performance and stability. Large websites such as RedHat, SUSE, Debian, GNU, GNOME, and KDE all use VSFTPD as their FTP servers. You can go to http://vsftpd.beasts.org/to understand the latest situation.

2. Install VSFTPD

2.1. Install the rhd9+ vsftpd-. 1.1.3-8. i386.rpm package

VSFTPD is easy to install. In rh93. execute "Main Menu"-"System Settings"-"Add/Remove Applications"-select FTP server-"Update" on the graphic interface ", you can also run the following command on the Character interface to complete the installation.
Rpm-ivh vsftpd-1.1.3-8.i386.rpm

2.2、vsftpd-1.2.0.tar.gz Installation

(1) Prerequisites

The "nobody" user is required in the default VSFTPD configuration. Add this user to the system. If the user already exists, the useradd command prompts accordingly.
[Root @ hpe45 root] # useradd nobody
Useradd: user nobody exists

The "/usr/share/empty" directory is required in the default VSFTPD configuration. In the system, if the directory already exists, the mkdir command prompts accordingly.
[Root @ hpe45 root] # mkdir/usr/share/empty/
Mkdir: cannot create directory '/usr/share/empty': File exists

When VSFTPD provides anonymous FTP services, you need an "ftp" user and a valid anonymous directory.
[Root @ hpe45 root] # mkdir/var/ftp/
[Root @ hpe45 root] # useradd-d/var/ftp
The subsequent operations are useful for the existence of ftp users.
[Root @ hpe45 root] # chown root. root/var/ftp
[Root @ hpe45 root] # chmod og-w/var/ftp

(2) Compile VSFTPD

Download the file from the official site to the/root directory and execute the following command:
[Root @ hpe45 root] # tar zxvf vsftpd-1.2.0.tar.gz
[Root @ hpe45 root] # cd vsftpd-1.2.0
[Root @ hpe45 vsftpd-1.2.0] # make

(3) install the compiled VSFTPD

Run "make install" to copy the compiled binary files and manuals to the corresponding directory. You may need to manually perform the following copy on rh93:
# Cp vsftpd/usr/local/sbin/vsftpd
[Root @ hpe45 vsftpd-1.2.0] # cp vsftpd. conf.5/usr/local/share/man/man5
[Root @ hpe45 vsftpd-1.2.0] # cp vsftpd.8/usr/local/share/man/man8
