Allow anonymous FTP? (Beware - allowed by default if you comment this out).
anonymous_enable=YES
#
Uncomment this to allow local users to log in.
When SELinux is enforcing check for SE bool ftp_home_dir
local_enable=YES
#
Uncomment this to enable any form of FTP write command.
write_enable=YES
#
Default umask for local users is 077. You may wish to change this to 022,
if your users expect that (022 is used by most other ftpd's)
local_umask=022
#
Uncomment this to allow the anonymous FTP user to upload files. This only
has an effect if the above global write enable is activated. Also, you will
obviously need to create a directory writable by the FTP user.
When SELinux is enforcing check for SE bool allow_ftpd_anon_write, allow_ftpd_full_access
anon_upload_enable=YES
[root@mysql200 Packages]# systemctl restart vsftpd
[root@mysql200 Packages]# setfacl -m u:ftp:rwx /var/ftp/pub/
[root@mysql200 Packages]# useradd wy
[root@mysql200 Packages]# echo onlyidc2018 | passwd --stdin wy
更改用戶 wy 的密碼 。
passwd：所有的身份驗證令×××已經成功更新。
[root@mysql200 Packages]# mkdir /var/ftp/wy
[root@mysql200 Packages]# setfacl -m u:wy:rwx /var/ftp/wy
