Configuring the FTP Service

20th. Configuring the FTP service

" What is FTP"

Maybe you're not a stranger to ftp , but do you know what ftp is? FTP is the abbreviation for file Transfer Protocol(document Transfer Protocol), and Chinese is called "Interfax protocol". Used for two-way transmission of control files on the Internet . At the same time, it is also an application (application). It allows users to connect their PC to all servers running the FTP protocol around the world, accessing a large number of programs and information on the server. The primary role of FTP is to have users connect to a remote computer (which runs an FTP server program) to see what files are on the remote computer and then copy the files from the remote computer to the local computer. or send the local computer's files to the remote computer. FTP uses more than NFS , so you must be skilled at configuring it.

" Configure FTP"

Install Redhat/centos System When you may be associated with the FTP installed, the system default with the FTP is vsftp, more commonly used, configuration is very simple. But I often use the ftp software for pure-ftpd. Because this software is more flexible and secure than the vsftp configuration. The following is the process of configuring pure-ftpd for the author:

Download the latest pure-ftp source package pure-ftpd-1.0.21.tar.bz2

# wget HTTP://SYSLAB.COMSENZ.COM/DOWNLOADS/LINUX/PURE-FTPD-1.0.21.TAR.BZ2

#tar JXVF pure-ftpd-1.0.21.tar.bz2

#cd pure-ftpd-1.0.21

./configure \

"--PREFIX=/USR/LOCAL/PUREFTPD" \

"--without-inetd" \

"--with-altlog" \

"--with-puredb" \

"--with-throttling" \

"--with-largefile" \

"--with-peruserlimits" \

"--with-tls" \

"--with-language=simplified-chinese"

#make && make Install

Start

With the configuration file

#mkdir/usr/local/pureftpd/etc

#cd Configuration-file

#cp pure-ftpd.conf/usr/local/pureftpd/etc/pure-ftpd.conf

#cp pure-config.pl/usr/local/pureftpd/sbin/pure-config.pl

#chmod 755/usr/local/pureftpd/sbin/pure-config.pl

Before starting pure-ftp, you need to modify the configuration file, configuration file for/usr/local/pureftpd/etc/pure-ftpd.conf, you can open to see, there is a lot of content, if you have good English, you can study it, here is my configuration file, If you are in trouble, copy the past directly.
