Linux vsftpd installation configuration to use (more)

In this paper, a number of previous articles written on many occasions with their own installation and configuration experience, written in more detail, the article finally ftp command set with all the configuration properties vsftpd.conf comments. If the problem please reply to me, thanks!

1. Directly to the vsftpd site ( download the latest source package tar.gz format
2. # Extract $ tar-zxf vsftpd-xx.tar.gz
$ Cd. / Vsftpd-xx
# Compile
make install
# If the make install does not install the file, you may need to manually execute the following command
cp vsftpd / usr / local / sbin / vsftpd
cp vsftpd.conf.5 / usr/local/share/man/man5
cp vsftpd.8 / usr/local/share/man/man8
cp vsftpd.conf / etc
cp vsfpd.xinetd / etc / xinetd.d / vsftpd
/ Etc / rc.d / init.d / xinetd restart or service xinetd restart
###### Without xinetd service, the command $ yum install xinetd
3. To set up an independent startup mode, then in / etc / xinetd.d / vsftpd file to disable = no change YES
In / etc / vsftpd.conf file:
Add listen = yes This turned into a STANDALONE standalone mode
4. Anonymous login configuration:
Changes (if you do not modify the default is) anonymous_enable = YES
anon_root = / sunwill # anonymous login directory
anon_no_anon_password = YES # do not prompt for a password is prompted for a password NO other attributes, such as for the article last part of the configuration properties list (anonymous general with anon), he will need to add or modify
6. The local user first cp RedHat / vsftpd.pam / etc / pam.d / ftp (copy local user authentication pam file, not this step will not be able to use local user login!)
Modify or add:
local_enable = YES
write_enable = YES
local_umask = 022
local_root = / sunwill # local user is logged on the default directory, if not for local users which are logged the original default directory, can be used usermod to modify (usermod-d / dir user).
7. Virtual user configuration:
(1). Generate virtual user password database file. In order to establish the password database file, first generate a text file. The document follows the format of the singular behavior of the user name, and even acts Password:
# Vi account.txt
(2). Generate password database file, and modify its permissions:

db_load-T-t hash-f. / account.txt / etc / vsftpd / account.db
chmod 600 / etc / vsftpd / account.db
(To change the user delete account.db, then db_load)

If not db_load can copy from the CD the first few on the db4 rpm file to install (rpm-ivh *. rpm).

Command $ rpm-q db4 check
If it has loaded, then download the db4-java-4.3.29-9.fc6.i386.rpm,
db4-tcl-4.3.29-9.fc6.i386.rpm, db4-utils-4.3.29-9.fc6.i386.rpm three packages
Db4 is not installed if more than download the db4-4.3.29-9.fc6.i386.rpm, db4-devel-4.3.29-9.fc6.i386.rpm two packages. Use rpm-ivh *. rpm to install the downloaded package
(3). Create a virtual user's PAM file. Add the following two lines:
# Vi / etc / pam.d /
auth required / lib / security / db = / etc / vsftpd / account
account required / lib / security / db = / etc / vsftpd / account
(4). Create a virtual user, set the user to access the directory, and set the virtual user access permissions:
useradd-d / ftpsite virtual_user
chmod 777 / ftpsite # # # allow all users to read and write operations through the steps of setting, / ftpsite is virtual_user user's home directory, the user is / ftpsite directory owners.
(5) in / etc / vsftpd.conf add
guest_enable = YES
guest_username = virtual_user
pam_service_name =
(6), stop here already in use account.txt ftp account password
As for the change the permissions for each user be admitted to add vsftpd.conf
user_config_dir = user profile directory, such as user_config_dir = / etc / vsftpd /
First mkdir / etc / vsftpd
Then create the directory and user name the same name documents, such as $ vi / etc / vsftpd / gou
And add the permissions attributes, as follows:
write_enable = NO # can be written
anono_upload_enable = NO # can upload their own view of other properties can configure the properties increased.
(7) start the ftp, / etc / local / sbin / vsftpd &
(8) Linux ftp command to connect: ftp # The following is the command input window information
Connected to
220 (vsFTPd 2.0.5)
530 Please login with USER and PASS.
530 Please login with USER and PASS.
KERBEROS_V4 rejected as an authentication type
Name ( root): gou
331 Please specify the password.
230 Login successful.
Remote system type is UNIX.
Using binary mode to transfer files.
As shown, said a successful connection
8. Settings switched on (1) We will set it in front of an independent startup mode, to start running in the / etc / vsftpd.conf the listen = YES listen = NO or the comment to (2) # vi / etc / xinetd.d / vsftpd
Will disable = YES to disable = NO
(3) # service xinetd restart ftp test available at this time
9. Ftp client commands
