前端之家收集整理的这篇文章主要介绍了CentOS 7安装配置FTP服务器前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

CentOS7下FTP服务器的安装配置。

假设我们有以下要求

路径 权限 备注
/ftp/open 公司所有人员包括来宾均可以访问 只读
/ftp/private 仅允许AliceJackTom三个人访问

AliceJack只允许下载,

Tom可以上传 均使用虚拟账户

安装FTP

//使用yum安装
# yum -yinstall ftp vsftpd
//或者使用rpm安装以下两个包
ftp-0.17-66.el7.x86_64
vsftpd-3.0.2-9.el7.x86_64
//另外需要安装db包,用来加密虚拟用户的账户信息
//这个包在centos7中默认已经安装了
# rpm -qf/usr/bin/db_load
libdb-utils-5.3.21-17.el7_0.1.x86_64

配置

# mkdir/ftp/open
做几个测试文件
# echo opentest > /ftp/open/open.txt
# echo filetest > /tmp/filetest1.txt

# touch /ftp/open/anontest.txt
//查看配置文件所在路径
# rpm -qc vsftpd
/etc/logrotate.d/vsftpd
/etc/pam.d/vsftpd
/etc/vsftpd/ftpusers
/etc/vsftpd/user_list
/etc/vsftpd/vsftpd.conf

# cd /etc/vsftpd/
//备份原有配置文件
# cp vsftpd.conf vsftpd.conf.origin

//创建密码明文文件
# vi/etc/vsftpd/vftpuser.txt
alice
P@ssw0rd
jack
P@ssw0rd
tom
P@ssw0rd

//根据明文创建密码DB文件
# db_load -T -t hash -f /etc/vsftpd/vftpuser.txt \
/etc/vsftpd/vftpuser.db

//查看密码数据文件
# file/etc/vsftpd/vftpuser.db
/etc/vsftpd/vftpuser.db: Berkeley DB (Hash,version9,native byte-order)

//创建vftpd的guest账户
# useradd -d/ftp/private -s /sbin/nologin vftpuser

# vi/etc/pam.d/vsftpd
将auth及account的所有配置行行均注释掉,添加如下内容
auth required pam_userdb.so db=/etc/vsftpd/vftpuser
account required pam_userdb.sodb=/etc/vsftpd/vftpuser
//打开配置文件
# vi/etc/vsftpd/vsftpd.conf
//在最后添加
anon_root=/ftp/open
virtual_use_local_privs=YES
guest_enable=YES
guest_username=vftpuser
chroot_local_user=YES
allow_writeable_chroot=YES
//设置自动启动
# systemctl enable vsftpd
ln -s'/usr/lib/systemd/system/vsftpd.service''/etc/systemd/system/multi-user.target.wants/vsftpd.service'

# systemctlstart vsftpd

//查看目前的状态
# systemctlstatus vsftpd
