这里选择proftpd作为FTP服务器

1、安装proftpd

emerge -av proftpd

2、配置proftpd

首先复制/etc/proftpd/proftpd.conf.sample

cp /etc/proftpd/proftpd.conf.sample /etc/proftpd/proftpd.conf

打开该文件进行适当的修改

下面是我的文件

ServerName "yan's ftp server!"
ServerType standalone
DefaultServer on
RequireValidShell off
AuthPAM on
AuthPAMConfig ftp
RequireValidShell off

# Listen on the standard FTP port 21.
Port 21

# New directories and files should not be group or world writable.
Umask 022

# To prevent DoS attacks set the maximum number of child processes
# to 30. If you need to allow more than 30 concurrent connections
# at once simply increase this value.
MaxInstances 30

# The server will run under ftp/ftp.
User ftp
Group ftp

# Every FTP sessions is "jailed" into the user's home directory.
DefaultRoot ~

# Generally files are overwritable.
AllowOverwrite on

# Disallow the use of the SITE CHMOD command.
<Limit SITE_CHMOD>
  DenyAll
</Limit>
SystemLog                       /var/log/proftpd.syslog
TransferLog                     /var/log/proftpd.transferlog

# A basic anonymous FTP account without an upload directory.
<Anonymous /home/ftp>
  User ftp
Group ftp

# Every FTP sessions is "jailed" into the user's home directory.
DefaultRoot ~

# Generally files are overwritable.
AllowOverwrite on

# Disallow the use of the SITE CHMOD command.
<Limit SITE_CHMOD>
  DenyAll
</Limit>
SystemLog                       /var/log/proftpd.syslog
TransferLog                     /var/log/proftpd.transferlog

# A basic anonymous FTP account without an upload directory.
<Anonymous /home/ftp>
  User ftp
  Group ftp

  # Clients can login with the username "anonymous" and "ftp".
  UserAlias anonymous ftp

  # Limit the maximum number of parallel anonymous logins to 10.
  MaxClients 10

  # Prohibit the WRITE command for the anonymous users.
  <Limit WRITE>
    DenyAll
  </Limit>
  <Limit LOGIN>
    Order               deny,allow
    Allow               from all
  </Limit>
</Anonymous>

3、启动服务

/etc/proftpd/proftpd start

如果正常这样默认的FTP配置的服务器就搭建好了。

本人遇到了一个问题，就是ftp用户登录的时候总是登录失败，看了下日志

Mar 16 12:05:46 yan-laptop proftpd[15868] yan-laptop: ProFTPD 1.3.3g (maint) (built Fri Mar 16 2012 10:36:06 CST) standalone mode STARTUP

Mar 16 12:11:00 yan-laptop proftpd[15868] yan-laptop: ProFTPD 1.3.3g standalone mode SHUTDOWN

解决方法：

去掉aclUSE标记，重新编译proftpd安装

USE="-acl" emerge proftpd

重启服务后问题解决。
