1. 安裝
執行 yum -y install vsftpd
註:(1)可通過 rpm -qa|grep vsftpd 檢查是否已安裝 vsftpd .
(2) 默認配置文件在/etc/vsftpd/vsftpd.conf
2 .為 vsftpd 服務器創建虛擬用戶
(1)選擇在根目錄或者用戶目錄下創建ftp文件夾:mkdir ftpfile
我是先進入根目錄創建文件夾 product ,再進入product 創建 ftpfile 文件夾。
cd /
mkdir product
cd product
mkdir ftpfile
(2)添加匿名用戶:useradd ftpuser -d /ftpfile -s /sbin/nologin
執行命令
useradd ftpuser -d /product/ftpfile -s /sbin/nologin
/product/ftpfile 為ftp文件夾。
因為先創建的文件夾所以會出現 目錄名重復 的警告。
(3)修改ftpfile權限: chown -R ftpuser.ftpuser /ftpfile
執行 chown -R ftpuser.ftpuser ./ftpfile
(4)重設ftpuser密碼:passwd ftpuser
執行 passwd ftpuser ,然後出入新密碼兩次。
3 .配置
執行
cd /etc/vsftpd
vim chroot_list
將ftp用戶名添加進去, :wq 保存退出。
vim /etc.selinux/config
修改為 SELINUX=disabled
執行 vim vsftpd.conf 編輯為
# Example config file /etc/vsftpd/vsftpd.conf # # The default compiled in settings are fairly paranoid.
