vsftpd 安装及设置

因机器上安装系统时没有安装vsftp，就下载了vsftp源码

1.修改安装文件

将vsftp源文件下的vsf_findlibs.sh文件中的/lib，/usr/lib全部换成了/lib64   解决64位操作系统路径问题

修改builddefs.h中的一行

#define VSF_BUILD_PAM改为#undef VSF_BUILD_PAM

解决使用系统帐号登录vsftp

2：make&&make install

3.[root@linuxsir vsftpd-2.0.1]# cp vsftpd.conf /etc/vsftpd.confBAK
[root@linuxsir vsftpd-2.0.1]# cp vsftpd /usr/sbin
[root@linuxsir vsftpd-2.0.1]# cp vsftpd /usr/local/sbin/vsftpd

cp /etc/vsftpd.conf /etc/vsftpd.conf

配置如下：

# Example config file /etc/vsftpd.conf## The default compiled in settings are fairly paranoid. This sample file# loosens things up a bit, to make the ftp daemon more usable.# Please see vsftpd.conf.5 for all compiled in defaults.## READ THIS: This example file is NOT an exhaustive list of vsftpd options.# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's# capabilities.## Allow anonymous FTP? (Beware - allowed by default if you comment this out).anonymous_enable=YES## Uncomment this to allow local users to log in.local_enable=YES## Uncomment this to enable any form of FTP write command.write_enable=YES## Default umask for local users is 077. You may wish to change this to 022,# if your users expect that (022 is used by most other ftpd's)local_umask=022anon_umask=022## Uncomment this to allow the anonymous FTP user to upload files. This only# has an effect if the above global write enable is activated. Also, you will# obviously need to create a directory writable by the FTP user.anon_upload_enable=YES## Uncomment this if you want the anonymous FTP user to be able to create# new directories.anon_mkdir_write_enable=YES## Activate directory messages - messages given to remote users when they# go into a certain directory.dirmessage_enable=YES## Activate logging of uploads/downloads.xferlog_enable=YES## Make sure PORT transfer connections originate from port 20 (ftp-data).connect_from_port_20=YES## If you want, you can arrange for uploaded anonymous files to be owned by# a different user. Note! Using "root" for uploaded files is not# recommended!#chown_uploads=YES#chown_username=whoever## You may override where the log file goes if you like. The default is shown# below.#xferlog_file=/var/log/vsftpd.log## If you want, you can have your log file in standard ftpd xferlog format#xferlog_std_format=YES## You may change the default value for timing out an idle session.#idle_session_timeout=600## You may change the default value for timing out a data connection.#data_connection_timeout=120## It is recommended that you define on your system a unique user which the# ftp server can use as a totally isolated and unprivileged user.#nopriv_user=ftpsecure## Enable this and the server will recognise asynchronous ABOR requests. Not# recommended for security (the code is non-trivial). Not enabling it,# however, may confuse older FTP clients.#async_abor_enable=YES## By default the server will pretend to allow ASCII mode but in fact ignore# the request. Turn on the below options to have the server actually do ASCII# mangling on files when in ASCII mode.# Beware that turning on ascii_download_enable enables malicious remote parties# to consume your I/O resources, by issuing the command "SIZE /big/file" in# ASCII mode.# These ASCII options are split into upload and download because you may wish# to enable ASCII uploads (to prevent uploaded scripts etc. from breaking),# without the DoS risk of SIZE and ASCII downloads. ASCII mangling should be# on the client anyway..#ascii_upload_enable=YES#ascii_download_enable=YES## You may fully customise the login banner string:#ftpd_banner=Welcome to blah FTP service.## You may specify a file of disallowed anonymous e-mail addresses. Apparently# useful for combatting certain DoS attacks.#deny_email_enable=YES# (default follows)#banned_email_file=/etc/vsftpd.banned_emails## You may specify an explicit list of local users to chroot() to their home# directory. If chroot_local_user is YES, then this list becomes a list of# users to NOT chroot().#chroot_list_enable=YES# (default follows)#chroot_list_file=/etc/vsftpd.chroot_list## You may activate the "-R" option to the builtin ls. This is disabled by# default to avoid remote users being able to cause excessive I/O on large# sites. However, some broken FTP clients such as "ncftp" and "mirror" assume# the presence of the "-R" option, so there is a strong case for enabling it.#ls_recurse_enable=YEScheck_shell=NO

这个配置文件是通过xinetd的方式启动vsftpd的，也就是说配置好vsftpd.conf 。要重新启动一下xinetd 

[root@linuxsir beinan]#/etc/init.d/xinetd restart 

当然要确保在 /etc/xinetd.d目录中存在vsftpd 这个文件，如果没有，要复制一个过去。

[root@linuxsir vsftpd-2.0.1]# cp xinetd.d/vsftpd /etc/xinetd.d

如果您xinetd模式启动不感兴趣，想通过standalone 来启动，还得进行如下操作。注意vsftpd服务器，在两种模式启动中，只能选一种方式。

在配置文件最后加一行。

listen=YES

还要删除 /etc/xinetd.d/目录中的vsftpd文件，如果通过 standalone 模式启动vsftpd服务器，还得运行命令。
4.添加有户测试：

代码:

[root@linuxsir beinan]# useradd -d /opt/bnnb -g ftp -s /sbin/nologin bnnb[root@linuxsir beinan]# passwd bnnb 设置密码Changing password for user bnnb. New UNIX password: 输入密码Retype new UNIX password:   再输入一次passwd: all authentication tokens updated successfully.
