vsftpd 安装与虚拟用户配置

测试环境:
centos 5.X 64bit
vsftpd 2.0

安装:yum -y install vsftpd

需求:
虚拟三个用户,使用同一个家目录。权限如下。
ftpadmin 读写删除
ftpuser 读写
ftp 读(下载)
目录为:/data
密码统一为:123456

一、创建虚拟用户数据库:
1、创建文件文件loginuser.txt
格式如下:

user_id
password
/home/loginuser.txt
ftpadmin
123456
ftpuser
123456
ftp
123456

2、生成数据库文件:

yum -y install db4-utils
db_load -T -t hash -f /home/loginuser.txt /etc/vsftpd/vsftpd_login.db
chmod 600 /etc/vsftpd/vsftpd_login.db

3、配置pam文件

# vi /etc/pam.d/vsftpd.vu
auth required /lib64/security/pam_userdb.so db=/etc/vsftpd/vsftpd_login
account required /lib64/security/pam_userdb.so db=/etc/vsftpd/vsftpd_login
#32位操作系统
auth required /lib/security/pam_userdb.so db=/etc/vsftpd/vsftpd_login
account required /lib/security/pam_userdb.so db=/etc/vsftpd/vsftpd_login

二、为虚拟用户创建本地系统用户
useradd opendoc -d /data -s /bin/false
chown opendoc.opendoc /data
三、vsftpd.conf配置
anonymous_enable=NO
local_enable=YES

#write_enable=NO
dirmessage_enable=YES
xferlog_enable=YES
xferlog_file=/var/log/vsftpd.log
connect_from_port_20=YES
xferlog_std_format=YES
listen=YES
listen_port=21
userlist_enable=YES
chroot_local_user=YES
tcp_wrappers=YES
guest_enable=YES
guest_username=opendoc
pam_service_name=vsftpd.vu
user_config_dir=/etc/vsftpd/vsftpd_user_conf
virtual_use_local_privs=YES
pasv_min_port=50000
pasv_max_port=60000
pasv_enable=yes
max_clients=200
max_per_ip=4
idle_session_timeout=600
ftpd_banner=Welcome to opendoc FTP service.

    anon_mkdir_write_enable=YES
    anon_other_write_enable=YES
    local_umask=022
    download_enable=Yes
    local_root=/data

    write_enable=YES
    anon_world_readable_only=NO
    anon_upload_enable=YES
    anon_mkdir_write_enable=YES
    anon_other_write_enable=YES
    local_umask=022
    download_enable=NO
    local_root=/data
  • vi /etc/vsftpd/vsftpd_user_conf/ftp 只能下载
    write_enable=NO
    anon_world_readable_only=NO
    anon_upload_enable=NO
    anon_mkdir_write_enable=NO
    anon_other_write_enable=NO
    local_umask=022
    download_enable=yes
    local_root=/data
