linux 编译安装proftpd并开启匿名登录（为临时补丁平台提供支持，解决欧拉操作系统vsftpd匿名登录异常的问题）

1、下载软件

#wet ftp://ftp.proftpd.org/distrib/source/proftpd-1.3.7a.tar.gz

或百度网盘：https://pan.baidu.com/s/1cvGwrgNrG5e1O6nE2dl5Eg  提取码：cztq 

2、解压

#tar -xvf proftpd-1.3.7a.tar.gz

3、编译安装

#cd /tmp/test/proftpd-1.3.7a/

#./configure --prefix=/usr/local/proftpd
#make && make install  

4、修改配置文件参考如下，允许匿名登录下载文件，默认home目录为/data/patch：

cd /usr/local/proftpd/etc/ && mv proftpd.conf proftpd.conf_bak

echo > /usr/local/proftpd/etc/proftpd.conf  << EOF

ServerName "ProFTPD server"
ServerIdent on "FTP Server ready."
ServerAdmin root@localhost
DefaultServer on
DefaultRoot ~ !adm
UseReverseDNS off

Group nobody
MaxInstances 200

<Directory "/patch">

<Limit ALL>

</Directory>
</IfModule>

</Anonymous>
</IfDefine>

EOF

5、解决“USER ftp (Login failed): Invalid shell: '/sbin/nologin'”

#echo /sbin/nologin >> /etc/shells

6、启动服务

nohup /usr/local/proftpd/sbin/proftpd  -DANONYMOUS_FTP
