部署ftp服务器
首先建立下载目录
mkdir  -p /home/down
然后下载proftpd源码包
wget ftp://ftp.proftpd.org/distrib/source/proftpd-1.3.2.tar.gz
接下来我们就来安装proftpd服务
 
tar -zxvf proftpd-1.3.2.tar.gz  #解压源码
cd proftpd-1.3.2   #进入源码包
./configure --prefix=/home/ftp/proftpd  #编译安装路径
make && make install  #编译二进制码和安装
cp contrib/dist/rpm/proftpd.init.d /etc/init.d/proftpd #【拷贝启动文件，是为了方便用service proftpd start 来启动ftp服务】
chmod o+x /etc/rc.d/init.d/proftpd #给启动脚本执行权限
vi /etc/init.d/proftpd #修改启动文件错误的路径

# description: ProFTPD is an enhanced FTP server with \

#              It features a very Apache-like configuration syntax, \
#              and a highly customizable server infrastructure, \
#              including support for multiple 'virtual' FTP servers, \
#              anonymous FTP, and permission-based directory visibility.

一下是proftp.conf的配置，安装自己需求修改
#########################################################
 
# This is a basic ProFTPD configuration file (rename it to
# 'proftpd.conf' for actual use.  It establishes a single server
# and a single anonymous login.  It assumes that you have a user/group
# "nobody" and "ftp" for normal operation and anon.
ServerName                      "www FTP"
ServerType                      standalone
DefaultServer                   on
# Port 21 is the standard FTP port.
Port                            21    #制定端口
# Don't use IPv6 support by default.
UseIPv6                         off #关闭ip6
# Umask 022 is a good standard umask to prevent new dirs and files
# from being group and world writable.
Umask                           002 #给上传文件权限
# 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 #最大连接数
# Set the user and group under which the server will run.
User                            nobody  #指定启动用户
Group                           nobody#制定启动组
# To cause every FTP user to be "jailed" (chrooted) into their home
# directory, uncomment this line.
DefaultRoot ~ !admin#指定能访问全部服务器资源的权限
# Normally, we want files to be overwriteable.
AllowOverwrite          on  #权限设置
UseReverseDNS           off
IdentLookups            off
# Bar use of SITE CHMOD by default
<Limit SITE_CHMOD>

建立ftp服务器用户最好不要给shell权限，推荐用一下命令建立用户
useradd -m  -d /down/ftp -g ftpm -s /sbin/nologin ftp123【本命令不见用户目录，制定上传下载目录，指定上传组，拒绝shell登入】
