ServerName "ProFTPD Default Installation"
ServerType standalone
DefaultServer on
分别表示:服务器名称,服务类型和默认服务状态!
后面的服务端口啊什么的我就省去不说了,说最关键的权限控制部分。
# Set the user and group under which the server will run.
User nobody
Group nogroup
注意看上面:以什么用户和什么组来运行服务。
更改为你现有的组和用户,这里为了管理上的方便和安全性上考虑,建议新建一个ftp组和ftp用户。
# To cause every FTP user to be "jailed" (chrooted) into their home
# directory, uncomment this line.
#DefaultRoot ~
是否允许用户进入用户的主目录,注意:可是适用/home替代
# Normally, we want files to be overwriteable.
AllowOverwrite on
是否具有重写的权利
# A basic anonymous configuration, no upload directories. If you do not
# want anonymous users, simply delete this entire <Anonymous> section.
<Anonymous ~ftp>
User ftp
Group ftp
# We want clients to be able to login with "anonymous" as well as "ftp"
UserAlias anonymous ftp
# Limit the maximum number of anonymous logins
MaxClients 10
# We want 'welcome.msg' displayed at login, and '.message' displayed
# in each newly chdired directory.
DisplayLogin welcome.msg
DisplayFirstChdir .message
# Limit WRITE everywhere in the anonymous chroot
<Limit WRITE>
DenyAll
</Limit>
</Anonymous>
这部分是匿名用户的定义其实也很简单。

启动不了,出现如下错误的解决方法
[iyunv@new-host sbin]# ./proftpd
- IPv4 getaddrinfo 'new-host' error: Name or service not known
- warning: unable to determine IP address of 'new-host'
- error: no valid servers configured
- Fatal: error processing configuration file '/usr/local/proftpd/etc/proftpd.conf'
getaddrinfo 'test' error: Name or service not known
- warning: unable to determine IP address of 'test'
- error: no valid servers configured
- Fatal: error processing configuration file '/etc/proftpd.conf'
解决:产生该问题是由于hosts文件里机器名未增加别名引起的。
#vi /etc/host
