Ftp=file Transter Protocol File Transfer Protocol

FTP common software has PURE-FTPD and vsftpd (System comes with)

The PURE-FTPD is more flexible than the vsftp configuration.

Official website Www.pureftpd.ort

1. Download the source package

wget http://download.pureftpd.org/pub/pure-ftpd/releases/pure-ftpd-1.0.42.tar.bz2

2. Unzip the source package

Tar jxvf pure-ftpd-1.0.42.tar.bz2

3. Compiling and installing the source code

CD pure-ftpd-1.0.42

./configure \

--PREFIX=/USR/LOCAL/PUREFTPD \

--WITHOUT-INETD \

--with-altlog \

--with-puredb \

--with-throttling \

--with-peruserlimits \

--with-tls

Make && make install

4.PURE-FTPD compile and install is done quickly, and there are few errors, it should be configured below:

Mkdir-p/usr/local/pureftpd/etc/# Create profile directory

CD configuration-file # Enter profile template directory

CP pure-ftpd.conf/usr/local/pureftpd/etc/pure-ftpd.conf # Copy the configuration template to the configuration file directory

CP pure-config.pl/usr/local/pureftpd/sbin/pure-config.pl # copy startup script to sbin directory

chmod 755/usr/local/pureftpd/sbin/pure-config.pl # Modify startup script executable permissions

5. Modify the configuration file, the template is comments and explanations, a lot of content, remove the explanation of the template:

5. Start PURE-FTPD

/usr/local/pureftpd/sbin/pure-config.pl/usr/local/pureftpd/etc/pure-ftpd.conf

The front is the startup program, followed by the configuration file

If it is successful, it displays a long line of information that starts with Running, or it is an error message. Heavy

It might be a bit cumbersome, after all, we don't have a startup script. Restart, you can use the following command to implement.

Killall PUREF-FTPD

cd/usr/local/pureftpd/;/sbin/pure-config.pl./etc/pure-ftpd.conf

6. Create a Test Catalog

Mkdir/tmp/ftp

chown-r wyp:wyp/tmp/ftp # prepare to map the virtual user to the system user Wyp, so have permissions.

7. Create User account password

/usr/local/pureftpd/bin/pure-pw useradd user1-uwyp-d/tmp/ftp/ Enter

Enter Password two times

-U associates the virtual user User1 with the system user Wyp, that is, using the User1 account to log in to FTP, will be WYP to read the file or download the file. The directory behind the-D is the FTP test directory, which allows User1 to access only the directory/tmp/ftp/.

8. The final step is to create a user information database file. (Key Step)

/USR/LOCAL/PUREFTPD/BIN/PURE-PW MKDB

PURE-PW can also list the current FTP account, of course, you can delete an account, we create an account:

/USR/LOCAL/PUREFTPD/BIN/PURE-PW Useradd user2-uwyp-d/tmp/ftp

/USR/LOCAL/PUREFTPD/BIN/PURE-PW MKDB

List Current Account:

/USR/LOCAL/PUREFTPD/BIN/PURE-PW List

The command to delete the account is:

/USR/LOCAL/PUREFTPD/BIN/PURE-PW Userdel User2

After-School troubleshooting

1./pureftpd/etc/pureftpd.pdb This file is my virtual user account password file, I can not use cat and vim to view the specific contents of the file, what command to view?

A: No, it is a binary file.

[Email protected] ~]#/USR/LOCAL/PUREFTPD/BIN/PURE-PW MKDB

This is mainly what to do with the household Information database files, but do not think it is used in where? A password or something? Solve, Baidu did not search for useful answers ~

A: MKDB is actually the user name password we previously set to log into a file, this file is pure-ftpd recognized files.
