pureftp默认支持匿名用户的，但是默认的匿名用户要登录必须满足一下两个条件：

1.确保有ftp用户
grep ftp /etc/passwd

2.确保有ftp用户主目录

usermod -d /data ftp

默认支持匿名用户上传，匿名用户上传是根据用户主目录权限来控制的

chown ftp:ftp /data/upload

匿名用户可调参数：

# Don’t allow authenticated users – have a public anonymous FTP only.
#是否只让匿名登录

# Disallow anonymous connections. Only allow authenticated users.
#不允许匿名连接，仅允许认证用户使用

# Are anonymous users allowed to create new directories ?
