Job for vsftpd.service failed because the control process exited with error code.

遇到个坑，需要弄一个ftp方便上传文件到服务器上，结果呢，安装了 vsftp 启动不了。

安装命令：yum install vsftp.

启动错误如下：

[root@iZbp1j0pytpghy9iy78q67Z webroot]# service vsftpd restart
Redirecting to /bin/systemctl restart vsftpd.service
Job for vsftpd.service failed because the control process exited with error code. See "systemctl status vsftpd.service" and "journalctl -xe" for details.
[root@iZbp1j0pytpghy9iy78q67Z webroot]# systemctl status vsftpd.service

在网上找的答案都是修改 vsftp 配置文件，但是修改之后还是不行。

根据提示查看错误方法如下：

[root@iZbp1j0pytpghy9iy78q67Z webroot]# systemctl status vsftpd

最后发现是端口号被占用了。

占用端口号的是 proftp 。

但是找不到配置文件，

最终记起来 这个 proftp  是安装 xampp 的时候安装的 配置文件在 xampp 的统一配置里。

气死我啦。
