本人小白，写下这篇博客意在记录踩过的坑，大神请绕道~
准备工作
安装自己喜欢的连接软件（一般是putty或者xshell），本人选择的是xshell，软件如图 ：
通过软件中的ssh连接连接上已经购买的服务器，具体账号密码可在阿里云的控制台设置 。
在控制台选择主机系统为CentOS7.2，连接上了之后首先先将服务器更新至最新版本。
yum -y update
接着安装编译源代码的开发工具 。
yum -y groupinstall "Development Tools"
FTP的安装
1.安装vsftpd的服务器和客户端
sudo yum install ftp vsftpd
2.安装一个加密工具
sudo yum install libdb-utils.x86_64
【大坑提醒】
不知道是我的个人情况还是通病，在使用VIM时会报
-bash: vim: command not found.
但是VI命令使用正常，遇到这种情况一般是VIM相关组件没有安装完成，可以通过命令查看
# rpm -qa |grep vim
VIM命令可用时返回为
vim-minimal-7.0.-.el5
vim-common-7.0.-7.2.el5
vim-enhanced-7.0.-7.2.el5
以上三条缺一不可，如果有空缺可用代码重新安装
yum -y install vim*
VIM的使用
进入编辑模式 a
进入命令行模式 esc
直接退出 :q
保存退出 :wq
vsftpd的配置
创建vsftp的登录用户和主目录
sudo useradd -d /home/myftp -s /sbin/nologin myftp（myftp是ftp的登录用户，替换成你自己的用户）
进入修改相对应用户的密码
passwd myftp
创建出vsftpd虚拟用户
sudo touch /etc/vsftpd/vftpuser.txt
文件里为
用户1
用户1密码
用户2
用户2密码
......
sudo db_load -T -t hash -f /etc/vsftpd/vftpuser.txt /etc/vsftpd/vftpuser.db
添加vsftpd的虚拟用户的验证
sudo vim /etc/pam.d/vsftpd
替换其中account和auth
session optional pam_keyinit.so force revoke
#auth required pam_listfile.so item=user sense=deny file=/etc/vsftpd/ftpusers onerr=succeed
#auth required pam_shells.so
#auth include password-auth
#account include password-auth
auth required pam_userdb.so db=/etc/vsftpd/vftpuser
account required pam_userdb.so db=/etc/vsftpd/vftpuser
session required pam_loginuid.so
session include password-auth
修改vsftpd的配置文件
sudo vim /etc/vsftpd/vsftpd.conf
以下为删除了注释的配置好的版本
# 是否运行匿名登录（NO）
anonymous_enable=NO
# 是否允许本地用户登录
local_enable=YES
# 允许ftp的任何写方式

# 日志文件的路径

# 日志文件的格式

#data_connection_timeout=
#
# 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().
# (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.
# 只监听ipv4的地址
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=YES pam_service_name=vsftpd
userlist_enable=YES
tcp_wrappers=YES
# 下面是自己添加的
anon_root=/home/pageftp/open
virtual_use_local_privs=YES
guest_enable=YES
guest_username=pageftp
# 虚拟用户的配置文件（可以对每一个虚拟用户进行单独的权限配置）
user_config_dir=/etc/vsftpd/vconf/
chroot_local_user=YES
allow_writeable_chroot=YES
配置虚拟用户的权限
sudo mkdir /etc/vsftpd/vconf/
touch 用户1 用户2 ……
vim 用户1
配置结果如下
cmds_allowed=ABOR,ACCT,APPE,CWD,CDUP,DELE,HELP,LIST,MODE,MDTM,MKD,NOOP,NLST,PASS,PASV,PORT,PWD,QUIT,REIN,RETR,RMD,RNFR,RNTO,SITE,SIZE
,STOR,STAT,STOU,STRU,SYST,TYPE,USER
write_enable=yes
download_enable=yes
anon_upload_enable=yes
anon_mkdir_write_enable=yes
anon_other_write_enable=yes
anon_world_readable_only=no
最后启动vsftpd服务
sudo systemctl enable vsftpd
sudo service vsftpd start
使用刚设置的用户名和密码通过FTP连接观察，本人选用软件FlashFXP。
