开始部署：

一、安装vsftp

sudo apt-get update && sudo apt-get -y install vsftpd

二、编辑配置文件

sudo vim /etc/vsftpd.conf

...
    listen=YES    #启用IPv4地址端口监听
...
    listen_ipv6=NO    #禁用IPv6地址端口监听
...
    anonymous_enable=YES    #启用匿名访问
...
    local_enable=YES    #启用本地用户登陆
...
    write_enable=YES    #启用任何形式的 FTP 写入命令
...
    ssl_enable=NO    #启用任何形式的 FTP 写入命令
...

三、重启vsftpd服务

sudo systemctl restart vsftpd

四、切换目录到ftp根目录

cd /srv/ftp

验证服务状态：

netstat -vatunp | grep 21
