一、下载安装：
1、网站中能够下载到profptd源码：
这个是软件源码ftp地址：
ftp://ftp.proftpd.org/distrib/source/
2、进入目录/root/download解压：
tar -zxvf proftpd-1.3.8.tar.gz #将源码压缩包解压到当前目录中
cd proftpd-1.3.8/ #进入到解压目录中
执行：
./configure --enable-nls --prefix=/usr/local/proftpd
#如果提示没有安装gcc，那么执行：
yum -y install gcc
或者下载gcc 下载网址：https://mirrors.tuna.tsinghua.edu.cn/gnu/gcc/
gcc-10.3.0.tar.gz
#安装完后：
make
make install
二、配置：
1、创建本地用户proftpd禁止ssh登录。创建之后所有虚拟用户使用这个系统用户访问文件：
root@localvm \~\]# useradd proftpd -d /home/proftpd -s /bin/false -u 1001
2、将ftp根目录权限设置成系统用户proftpd上：
chown -R proftpd:proftpd /data/ftpdata
3、创建虚拟用户admin虚拟到proftpd上：
/usr/local/proftpd/bin/ftpasswd --passwd --uid=1001 --gid=1001 --home=/data/ftpdata --shell=/sbin/nologin --file=/usr/local/proftpd/etc/ftpd.passwd --name=admin
/usr/local/proftpd/bin/ftpasswd --passwd --uid=1001 --gid=1001 --home=/data/ftpdata --shell=/sbin/nologin --file=/usr/local/proftpd/etc/ftpd.passwd --name=shangchuan
/usr/local/proftpd/bin/ftpasswd --passwd --uid=1001 --gid=1001 --home=/data/ftpdata --shell=/sbin/nologin --file=/usr/local/proftpd/etc/ftpd.passwd --name=xiazai
#上面命令的说明：
#name是登陆ftp的用户名 file是密码文件位置 home是ftp用户的根目录
/\*执行后显示：
ftpasswd: using alternate file: /usr/local/proftpd/etc/ftpd.passwd
ftpasswd: creating passwd entry for user admin
ftpasswd: /sbin/nologin is not among the valid system shells. Use of
ftpasswd: "RequireValidShell off" may be required, and the PAM
ftpasswd: module configuration may need to be adjusted.
输入密码：
\*/
/usr/local/proftpd/bin/ftpasswd --group --file=/usr/local/proftpd/etc/ftp.group --gid=1001 --name=proftpd --member=admin
#创建用户组，生成配置文件 member将创建的用户添加到用户组中
2、ftp用户配置要求：admin 权限不限 shangchuan 只能上传文件夹上传 xiazai 只能下载文件下载:
