Linux下搭建FTP文件服务器
1、下载并安装vsftpd.rpm
vsftp.rpm下载地址
#查看系统是否安装了ftp，若安装了vsftp，使用这个命令会在屏幕上显示vsftpd的版本
rpm -qa|grep vsftpd
#卸载ftp
rpm -e vsftpd
#安装vsftp,先cd去所在目录
rpm -ivh --nodeps --force vsftpd-2.2.2-24.el6.x86_64.rpm
#设置开机启动
chkconfig vsftpd on
管理vsftpd相关命令：
启动vsftpd: service vsftpd start
停止vsftpd: service vsftpd stop
重启vsftpd: service vsftpd restart
#关闭sellinux
1、立即关闭
setenforce 0
2、重启也关闭
vi /etc/selinux/config
#修改
SELINUX=disabled
3、查看是否关闭
getenforce
2、配置防火墙，开放21端口
vi /etc/sysconfig/iptables
在REJECT行之前添加如下代码
-A INPUT -p tcp -m state --state NEW -m tcp --dport 21 -j ACCEPT保存和关闭文件，重启防火墙
service iptables start3、配置vsftpd服务器
useradd ftpUser -s /sbin/nologin -d /home/yangxi #1、创建个普通用户用于连接ftp，-d的家目录是ftp连接上默认访问的。这个禁止登录，是禁止远程连接服务器，不是禁止登录ftp
passwd ftpUser #敲回车，设置密码
ftpusers 是黑名单，禁止使用vsftpd的用户列表文件。记录不允许访问FTP服务器的用户名单
user_list 禁止或允许使用vsftpd的用户列表文件。这个文件中指定的用户缺省情况（即在/etc/vsftpd/vsftpd.conf中设置userlist_deny=YES）
在 vsftpd.conf 主配置文件中
# 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.
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.
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
#
# The target log file can be vsftpd_log_file or xferlog_file.
# This depends on setting xferlog_std_format parameter
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=whoever
#
# The name of log file when xferlog_enable=YES and xferlog_std_format=YES
# WARNING - changing this filename affects /etc/logrotate.d/vsftpd.log
#xferlog_file=/var/log/xferlog
#
# Switches between logging into vsftpd_log_file and xferlog_file files.
# NO writes to vsftpd_log_file, YES to xferlog_file
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.
# 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
# directory. If chroot_local_user is YES, then this list becomes a list of
# users to NOT 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. To listen on IPv4 and IPv6
# sockets, 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
local_root=/var/ftp重启：service vsftpd restart，我这里photos是我自己加的
4、Java对接
#添加依赖

nginx添加路由配置：
