VsFTP+本地文件认证+SSl实现虚拟用户配置

Posted 2020-08-10 Python学习之路

1.实验环境：

 

[[email protected] ~]# cat /etc/centos-release 
CentOS release 6.8 (Final)
[[email protected] ~]# uname -r
2.6.32-642.1.1.el6.x86_64

2.安装、启动vsftpd，并设置开机启动

[[email protected] ~]# yum install -y vsftpd
[[email protected] ~]# /etc/init.d/vsftpd start
Starting vsftpd for vsftpd:                    [  OK  ]
[[email protected] ~]# netstat -anplt|grep 21
tcp        0      0 0.0.0.0:21                  0.0.0.0:*   
[[email protected] ~]# chkconfig vsftpd on
[[email protected] ~]# chkconfig --list vsftpd
vsftpd          0:off   1:off   2:on    3:on    4:on    5:on    6:off

3.配置虚拟用户

 

[[email protected] ~]# cd /etc/vsftpd/
[[email protected] /etc/vsftpd]# cp vsftpd.conf vsftpd.conf_bak_`date +%F`
[[email protected] /etc/vsftpd]# ls

[[email protected] /etc/vsftpd]# groupadd -g 1500 vftpuser && useradd -g vftpuser -u 1500 -s /sbin/nologin -d /vftpuser vftpuser
[[email protected] /etc/vsftpd]# chown -R vftpuser.vftpuser /vftpuser/ 
[[email protected] /etc/vsftpd]# chmod go+rx /vftpuser/
[[email protected] /etc/vsftpd]# ls -ld /vftpuser/
