一、安装
复制代码
代码如下:
sudo apt-get install proftpd
安装过程中会让选择运行模式：Standalone和Inetd ， 前者是单一服务器模式，后者是超级服务器模式，
我选的Standalone 。
二、配置
复制代码
代码如下:
sudo vim /etc/shells
加入如下代码
复制代码
代码如下:
/bin/false
新建用户ftpuser1和用户组ftp并设置密码，此用户不需要有效的shell(更安全)，所以选择/bin/false
给fptuser1
复制代码
代码如下:
sudo groupadd ftp
sudo useradd ftpuser1 -p pass -g ftp -d /home/ftp -s /bin/false
在/home/ftp目录下新建upload和download目录并修改权限
复制代码
代码如下:
cd /home/ftp
sudo mkdir download
sudo mkdir upload
cd /home
sudo chmod 755 ftp
cd /home/ftp
sudo chmod 755 download
sudo chmod 777 upload
三、修改proftpd核心配置文件proftpd.conf
复制代码
代码如下:
sudo vim /etc/proftpd/proftpd.conf
#
# /etc/proftpd/proftpd.conf -- This is a basic ProFTPD configuration file.
# To really apply changes reload proftpd after modifications.
#
# Includes DSO modules
Include /etc/proftpd/modules.conf
# Set off to disable IPv6 support which is annoying on IPv4 only boxes.
UseIPv6 off # 我们不需要IPv6，所以off
ServerName "xiaoyigeng's FTP Server" # 修改服务器名
ServerType standalone # 服务器运行模式，这里填standalone，也可以选
inetd
DeferWelcome on # 用户登陆时是否显示欢迎信息
MultilineRFC2228 on
DefaultServer on
ShowSymlinks on
TimeoutNoTransfer 600
TimeoutStalled 600 # 可以降到100
TimeoutIdle 1200 # 发呆超时
DisplayLogin welcome.msg # 如果上边DeferWelcom设置成on ， 则显示
welcome.msg中的内容
DisplayFirstChdir .message # 更改目录时显示的内容
ListOptions "-l"
DenyFilter /*.*/
# Use this to jail all users in their homes
DefaultRoot /home/ftp # ftp用户被限制在这个目录中
# Users require a valid shell listed in /etc/shells to login.
# Use this directive to release that constrain.
# RequireValidShell off # 匿名用户要选on
# Port 21 is the standard FTP port.
Port 21 # 服务运行的端口
# In some cases you have to specify passive ports range to by-pass
# firewall limitations. Ephemeral ports can be used for that, but
# feel free to use a more narrow range.
# PassivePorts 49152 65534 # PASV模式下用到的端口
# If your host was NATted, this option is useful in order to
# allow passive tranfers to work. You have to use your public
# address and opening the passive ports used on your firewall as well.
# MasqueradeAddress 1.2.3.4
# 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. Note that this ONLY works
# in standalone mode, in inetd mode you should use an inetd server
# that allows you to limit maximum number of processes per service
# (such as xinetd)
MaxInstances 30
# Set the user and group that the server normally runs at.
User nobody # 服务器运行在nobody用户下
Group nobody # 服务器运行在nobody组下
# Umask 022 is a good standard umask to prevent new files and dirs
# (second parm) from being group and world writable.
Umask 022 022 # 默认新建文件的权限
# Normally, we want files to be overwriteable.

# in downloads. That is not needed for uploads rates.
#
# UseSendFile off
# Choose a SQL backend among MySQL or PostgreSQL.
# Both modules are loaded in default configuration, so you have to specify the backend
# or comment out the unused module in /etc/proftpd/modules.conf.
# Use 'mysql' or 'postgres' as possible values.
#

四、启动、停止、重启服务器
复制代码
代码如下:
sudo /etc/init.d/proftpd start
sudo /etc/init.d/proftpd stop
sudo /etc/init.d/proftpd restart
五、维护
可以到/var/log/proftpd目录查看日志
查看ftp服务器负载命令 ftptop
查看什么认登陆服务器 ftpwho
【ubuntu服务器安装proftpd ubuntu服务器安装出现错误】PS:proftpd中Limit的使用介绍
我们用到的比较多的可能是Limit的使用 ， Limit大致有以下动作 ， 基本能覆盖全部的权限了 。
CMD：Change Working Directory 改变目录
MKD：MaKe Directory 建立目录的权限
RNFR： ReName FRom 更改目录名的权限
DELE：DELEte 删除文件的权限
RMD：ReMove Directory 删除目录的权限
RETR：RETRieve 从服务端下载到客户端的权限
STOR：STORe 从客户端上传到服务端的权限
READ：可读的权限 ， 不包括列目录的权限 ， 相当于RETR，STAT等
WRITE：写文件或者目录的权限，包括MKD和RMD
DIRS：是否允许列目录，相当于LIST，NLST等权限，还是比较实用的
ALL：所有权限
LOGIN：是否允许登陆的权限
针对上面这个Limit所应用的对象，又包括以下范围
AllowUser 针对某个用户允许的Limit
DenyUser 针对某个用户禁止的Limit
AllowGroup 针对某个用户组允许的Limit
DenyGroup 针对某个用户组禁止的Limit
AllowAll 针对所有用户组允许的Limit
DenyAll 针对所有用户禁止的Limit
关于限制速率的参数为：
TransferRate STOR|RETR 速度（Kbytes/s） user 使用者
