配置ftp环境

在mnt目录下目录并挂载

# mkdir /mnt/yw

# mount /dev/sr0 /mnt/yw/

--------------------------------------------------

mount: /dev/sr0 is write-protected, mounting read-only

--------------------------------------------------

cd来到Packages目录

# cd /mnt/yw/Packages/

查找目录下安装包命令：

# ls | grep vsftpd   

---------------------------

vsftpd-3.0.2-9.el7.x86_64.rpm

用rpm命令-ivh下载安装包

#rpm -ivh vsftpd-3.0.2-9.el7.x86_64.rpm

关闭防火墙：

# iptables -F

# iptables -X

# setenforce 0

重启服务：

#systemctl restart vsftpd

用status查看一下服务是否启动了

# systemctl status vsftpd
