6.1 添加用戶
```bash
vim user_list
ftptest
6.2 修改配置文件
vim /etc/vsftpd/vsftpd.conf
userlist_enable=YES #啟動(dòng)用戶列表
userlist_deny=NO #決定是否對(duì)用戶列表的用戶拒絕訪問(wèn)ftp
6.3我的完整配置文件
# 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=YES
#
# 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=YES
#
# 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=YES
chown_username=ftpuser
#
# 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 blah 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
ascii_upload_enable=YES
#
# You may fully customise the login banner string:
ftpd_banner=Welcome to blah 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=NO
#
# 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=YES
pam_service_name=vsftpd
userlist_enable=YES
tcp_wrappers=YES
userlist_deny=NO
allow_writeable_chroot=YES
## 7.開(kāi)始添加目標(biāo)用戶,并為其設(shè)置主目錄
```bash
usera**加粗樣式**dd -d 目錄 -m 目錄 用戶 //-d 目錄 指定用戶主目錄,如果此目錄不存在,則同時(shí)使用-m選項(xiàng),可以創(chuàng)建主目錄。
passwd 用戶名 //設(shè)置密碼
chmod 755 目錄 //以root的視角去修改當(dāng)前目錄的權(quán)限
chown -R ftp用戶名:組名 目錄 //組名可不寫,修改目錄所屬者
systemctl start vsftpd //重啟ftp
8. 將用戶添加列表
vim user_list
ftptest
9 訪問(wèn)
ftp://ftptest:ftptest@node01
ftp://node01 #需要再輸入用戶名和密碼
用戶名:ftptest
密碼 :ftptest
10. ftp 啟動(dòng)關(guān)閉命令
啟動(dòng)vsftpd服務(wù):systemctl start vsftpd
停止vsftpd服務(wù):systemct stop vsftpd
重啟vsftpd服務(wù):systemctl restart vsftpd

12.常遇到的問(wèn)題
getsebool -a | grep ftp 執(zhí)行命令這個(gè)出不來(lái) 就SELINUX=disabled 修改為1
[root@basenode shell]# getsebool -a | grep ftp
ftpd_anon_write --> off
ftpd_connect_all_unreserved --> off
ftpd_connect_db --> off
ftpd_full_access --> on
ftpd_use_cifs --> off
ftpd_use_fusefs --> off
ftpd_use_nfs --> off
ftpd_use_passive_mode --> off
httpd_can_connect_ftp --> off
httpd_enable_ftp_server --> off
tftp_anon_write --> off
tftp_home_dir --> on
SELINUX=disabled 修改為1
[root@basenode shell]# vi /etc/sysconfig/selinux
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
# SELINUX=enforcing
#SELINUX=disabled
SELINUX=1
# SELINUXTYPE= can take one of three values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
在修改
setsebool -P allow_ftpd_full_access on
setsebool -P ftp_home_dir on
13 常用命令
service vsftpd start //啟動(dòng)ftp服務(wù)(同 systemctl start vsftpd.service )
service vsftpd restart //重啟ftp服務(wù)
service VSftod stop //關(guān)閉ftp
service vsftpd status //查看ftp狀態(tài)
netstat -an | grep 21 //查看服務(wù)有沒(méi)有啟動(dòng)
chkconfig vsftpd on //開(kāi)機(jī)自啟
14將ftp 的文件下載 到指定目錄
第一種方式 是將文件名 包含時(shí)間 的 名稱 匹配文件名稱進(jìn)行下載
#!/bin/bash
#獲取性能系統(tǒng)小時(shí)粒度的指標(biāo)數(shù)據(jù)
u=ftptest # ftp用戶名
p=123456789 #ftp密碼
ip=192.168.1.180 # ftp 地址
#T=`date -d yesterday +%Y%m%d`
T=`date +%Y%m%d`
#寫入日志
echo "(`date`) get data start...." >> /opt/logs/getdata.log
echo "===================================================" >> /opt/logs/getdata.log
ftp -n <<EOF
open $ip
user $u $p
binary
cd /home/ftptest/ # ftp 的目錄
lcd /opt/datas # 目標(biāo)目錄
hash
prompt off
mget *$T*
cd /home/ftptest/
mget *$T*
close
bye
EOF
echo "download from ftp successfully"
第二種是是通過(guò)目錄文件夾 新建一個(gè)日期 然后更加日期進(jìn)行下載 到另一個(gè)目錄
#!/bin/sh
#source dircotry
src="/home/ftptest"
yestoday_date=$(date "+%Y%m%d" -d "1 days ago")
echo "-----" $yestoday_date
[ ! -d ${src}/${yestoday_date} ] && mkdir ${src}/${yestoday_date} -p
ftp -v -n 192.168.1.180 << EOF
user ftptest 123456789
cd /home/ftptest/${yestoday_date}
lcd ${src}/${yestoday_date}
mget *
y
exit
EOF
第三種是直接下載
#!/bin/sh
ftp -v -n 192.168.1.180<<EOF
user ftptest 123456789
binary
cd /home/ftptest/
lcd /opt/datas
prompt
mget *
bye
EOF
echo "download from ftp successfully"
