FTP配置文件vsftpd.conf
第一步：安装Contos7系统
第二步：检查是否安装FTP
命令的方法：
[root@umboyserver vsftpd]# ps -aux | grep ftpd
[root@umboyserver vsftpd]# netstat -na | grep 21
第三步：安装FTP
#安装vsftpd
[root@umboyserver vsftpd]# yum install -y vsftpd
#设置开机启动
[root@umboyserver vsftpd]# systemctl enable vsftpd.service
# 重启
[root@umboyserver vsftpd]# service vsftpd restart
# 查看vsftpd服务的状态
[root@umboyserver vsftpd]# systemctl status vsftpd.service
第四步：配置FTP
1、配置vsftp.conf文件
#备份配置文件
[root@umboyserver vsftpd]# cp /etc/vsftpd/vsftpd.conf /etc/vsftpd/vsftpd.conf.bak
#执行以下命令
[root@umboyserver vsftpd]# sed -i "s/anonymous_enable=YES/anonymous_enable=NO/g" '/etc/vsftpd/vsftpd.conf'
[root@umboyserver vsftpd]# sed -i "s/#anon_upload_enable=YES/anon_upload_enable=NO/g" '/etc/vsftpd/vsftpd.conf'
[root@umboyserver vsftpd]# sed -i "s/#anon_mkdir_write_enable=YES/anon_mkdir_write_enable=YES/g" '/etc/vsftpd/vsftpd.conf'
[root@umboyserver vsftpd]# sed -i "s/#chown_uploads=YES/chown_uploads=NO/g" '/etc/vsftpd/vsftpd.conf'
[root@umboyserver vsftpd]# sed -i "s/#async_abor_enable=YES/async_abor_enable=YES/g" '/etc/vsftpd/vsftpd.conf'
[root@umboyserver vsftpd]# sed -i "s/#ascii_upload_enable=YES/ascii_upload_enable=YES/g" '/etc/vsftpd/vsftpd.conf'
[root@umboyserver vsftpd]# sed -i "s/#ascii_download_enable=YES/ascii_download_enable=YES/g" '/etc/vsftpd/vsftpd.conf'
[root@umboyserver vsftpd]# sed -i "s/#ftpd_banner=Welcome to blah FTP service./ftpd_banner=Welcome to FTP service./g" '/etc/vsftpd/vsftpd.conf'
#在vsftpd.conf中将一下几个地方的注释去掉
[root@umboyserver vsftpd]# vi /etc/vsftpd/vsftpd.conf
anonymous_enable=NO
local_enable=YES
xferlog_file=/var/log/xferlog
ascii_upload_enable=YES
ascii_download_enable=YES
chroot_local_user=YESchroot_list_enable=YESchroot_list_file=/etc/chroot_list
#在vsftpd.conf中将一下几个地方添加注释
listen=YES
listen_ipv6=YES
#添加下列内容到vsftpd.conf末尾
use_localtime=YES
listen_port=21
chroot_local_user=YES
idle_session_timeout=300
guest_enable=YES
guest_username=vsftpd
user_config_dir=/etc/vsftpd/vconf
data_connection_timeout=1
virtual_use_local_privs=YES
pasv_min_port=10060
pasv_max_port=10090
accept_timeout=5
connect_timeout=1
2. 建立用户文件
#第一行用户名，第二行密码，不能使用root为用户名
[root@umboyserver vsftpd]# vi /etc/vsftpd/virtusers
chris
123456
chang
123456
#在/etc/vsftpd下新建chroot_list,加入登陆用户的名字
[root@umboyserver vsftpd]# vi /etc/vsftpd/chroot_list
test
123456
3. 生成用户数据文件
[root@umboyserver vsftpd]# db_load -T -t hash -f /etc/vsftpd/virtusers /etc/vsftpd/virtusers.db
#设定PAM验证文件，并指定对虚拟用户数据库文件进行读取
[root@umboyserver vsftpd]# chmod 600 /etc/vsftpd/virtusers.db
4. 修改/etc/pam.d/vsftpd文件
# 修改前先备份
[root@umboyserver vsftpd]# cp /etc/pam.d/vsftpd /etc/pam.d/vsftpd.bak
# 将auth及account的所有配置行均注释掉
[root@umboyserver vsftpd]# vi /etc/pam.d/vsftpd
auth sufficient /lib64/security/pam_userdb.so db=/etc/vsftpd/virtusers
account sufficient /lib64/security/pam_userdb.so db=/etc/vsftpd/virtusers
# 如果系统为32位，上面改为lib
5. 新建系统用户vsftpd，用户目录为/home/vsftpd
#用户登录终端设为/bin/false(即：使之不能登录系统)
[root@umboyserver vsftpd]# useradd vsftpd -d /home/vsftpd -s /bin/false
[root@umboyserver vsftpd]# chown -R vsftpd:vsftpd /home/vsftpd
6.建立虚拟用户个人配置文件
[root@umboyserver vsftpd]# mkdir /etc/vsftpd/vconf
[root@umboyserver vsftpd]# cd /etc/vsftpd/vconf
#这里建立两个虚拟用户配合文件
[root@umboyserver vsftpd]# touch chris chang
#建立用户根目录
[root@umboyserver vsftpd]# mkdir -p /home/vsftpd/chris/
#编辑chris用户配置文件，内容如下，其他用户类似
[root@umboyserver vsftpd]# vi chris
local_root=/home/vsftpd/chris/
write_enable=YES
anon_world_readable_only=NO
anon_upload_enable=YES
anon_mkdir_write_enable=YES
anon_other_write_enable=YES
7. 防火墙设置
[root@umboyserver vsftpd]# vi /etc/sysconfig/iptables
#编辑iptables文件，添加如下内容，开启21端口
[root@umboyserver vsftpd]# -A INPUT -m state --state NEW -m tcp -p tcp --dport 21 -j ACCEPT
8.设置FTP上传下载的权限
[root@umboyserver vsftpd]# setsebool allow_ftpd_full_access 1
[root@umboyserver vsftpd]# setsebool allow_ftpd_use_cifs 1
[root@umboyserver vsftpd]# setsebool allow_ftpd_use_nfs 1
[root@umboyserver vsftpd]# setsebool ftp_home_dir 1
[root@umboyserver vsftpd]# setsebool httpd_enable_ftp_server 1
[root@umboyserver vsftpd]# setsebool tftp_anon_write 1
第五步：重启FTP
systemctl start vsftpd
systemctl restart vsftpd
第六步：在FTP客户端链接
输入IP地址
用户名：test
密码：123456
端口：21
#附上vsftpd.conf文件的所有内容：
# Example config file /etc/vsftpd/vsftpd.conf
#
# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
# Please see vsftpd.conf.5 for all compiled in defaults.
#
# READ THIS: This example file is NOT an exhaustive list of vsftpd options.
# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
# capabilities.
#
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
anonymous_enable=NO
#
# Uncomment this to allow local users to log in.
# When SELinux is enforcing check for SE bool ftp_home_dir
local_enable=YES
#
# Uncomment this to enable any form of FTP write command.
write_enable=YES
#
# Default umask for local users is 077. You may wish to change this to 022,
# if your users expect that (022 is used by most other ftpd's)
local_umask=022
#
# Uncomment this to allow the anonymous FTP user to upload files. This only
# has an effect if the above global write enable is activated. Also, you will
# obviously need to create a directory writable by the FTP user.
# When SELinux is enforcing check for SE bool allow_ftpd_anon_write, allow_ftpd_full_access
anon_upload_enable=NO
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
anon_mkdir_write_enable=YES
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory.
dirmessage_enable=YES
#
# Activate logging of uploads/downloads.
xferlog_enable=YES
#
# Make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=YES
#
# If you want, you can arrange for uploaded anonymous files to be owned by
# a different user. Note! Using "root" for uploaded files is not
# recommended!
chown_uploads=NO
#chown_username=whoever
#
# You may override where the log file goes if you like. The default is shown
# below.
xferlog_file=/var/log/xferlog
#
# If you want, you can have your log file in standard ftpd xferlog format.
# Note that the default log file location is /var/log/xferlog in this case.
xferlog_std_format=YES
#
# You may change the default value for timing out an idle session.
#idle_session_timeout=600
#
# You may change the default value for timing out a data connection.
#data_connection_timeout=120
#
# It is recommended that you define on your system a unique user which the
# ftp server can use as a totally isolated and unprivileged user.
#nopriv_user=ftpsecure
#
# Enable this and the server will recognise asynchronous ABOR requests. Not
# recommended for security (the code is non-trivial). Not enabling it,
# however, may confuse older FTP clients.
async_abor_enable=YES
#
# By default the server will pretend to allow ASCII mode but in fact ignore
# the request. Turn on the below options to have the server actually do ASCII
# mangling on files when in ASCII mode. The vsftpd.conf(5) man page explains
# the behaviour when these options are disabled.
# Beware that on some FTP servers, ASCII support allows a denial of service
# attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
# predicted this attack and has always been safe, reporting the size of the
# raw file.
# ASCII mangling is a horrible feature of the protocol.
ascii_upload_enable=YES
ascii_download_enable=YES
#
# You may fully customise the login banner string:
ftpd_banner=Welcome to FTP service.
#
# You may specify a file of disallowed anonymous e-mail addresses. Apparently
# useful for combatting certain DoS attacks.
#deny_email_enable=YES
# (default follows)
#banned_email_file=/etc/vsftpd/banned_emails
#
# You may specify an explicit list of local users to chroot() to their home
# directory. If chroot_local_user is YES, then this list becomes a list of
# users to NOT chroot().
# (Warning! chroot'ing can be very dangerous. If using chroot, make sure that
# the user does not have write access to the top level directory within the
# chroot)
chroot_local_user=YES
chroot_list_enable=YES
# (default follows)
chroot_list_file=/etc/vsftpd/chroot_list
#
# You may activate the "-R" option to the builtin ls. This is disabled by
# default to avoid remote users being able to cause excessive I/O on large
# sites. However, some broken FTP clients such as "ncftp" and "mirror" assume
# the presence of the "-R" option, so there is a strong case for enabling it.
#ls_recurse_enable=YES
#
# When "listen" directive is enabled, vsftpd runs in standalone mode and
# listens on IPv4 sockets. This directive cannot be used in conjunction
# with the listen_ipv6 directive.
#listen=YES
#
# This directive enables listening on IPv6 sockets. By default, listening
# on the IPv6 "any" address (::) will accept connections from both IPv6
# and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6
# sockets. If you want that (perhaps because you want to listen on specific
# addresses) then you must run two copies of vsftpd with two configuration
# files.
# Make sure, that one of the listen options is commented !!
#listen_ipv6=NO
