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。

1 yum -y update 

接着安装编译源代码的开发工具 。

1 yum -y groupinstall "Development Tools" 

FTP的安装

1.安装vsftpd的服务器和客户端

1 sudo yum install ftp vsftpd

2.安装一个加密工具

1 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

1 # rpm -qa |grep vim

VIM命令可用时返回为

1 vim-minimal-7.0.109-6.el5
2 vim-common-7.0.109-7.2.el5
3 vim-enhanced-7.0.109-7.2.el5

以上三条缺一不可，如果有空缺可用代码重新安装

1 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

1 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

1 passwd myftp

创建出vsftpd虚拟用户

1 sudo touch /etc/vsftpd/vftpuser.txt

文件里为

1 用户1
2 用户1密码
3 用户2
4 用户2密码
5 ......

1 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

1 sudo vim /etc/pam.d/vsftpd 

替换其中account和auth

1 session    optional     pam_keyinit.so    force revoke
2 #auth       required    pam_listfile.so item=user sense=deny file=/etc/vsftpd/ftpusers onerr=succeed
3 #auth       required    pam_shells.so
4 #auth       include     password-auth
5 #account    include     password-auth
6 auth required pam_userdb.so db=/etc/vsftpd/vftpuser
7 account required pam_userdb.so db=/etc/vsftpd/vftpuser
8 session    required     pam_loginuid.so
9 session    include      password-auth

修改vsftpd的配置文件

1 sudo vim /etc/vsftpd/vsftpd.conf 

以下为删除了注释的配置好的版本

  1 # 是否运行匿名登录（NO）
  2 anonymous_enable=NO
  3 # 是否允许本地用户登录
  4 local_enable=YES
  5 # 允许ftp的任何写方式
  6 write_enable=YES
  7 # 文件创建只有的权限是755=（777-022）
  8 local_umask=022
  9 # 是否允许匿名用户上传文件
 10 #anon_upload_enable=YES
 11 # 是否允许匿名用户创建文件或者删除文件
 12 #anon_mkdir_write_enable=YES
 13 # 用户进入目录信息提示
 14 dirmessage_enable=YES
 15 # 是否允许vsftp的日志
 16 xferlog_enable=YES
 17 # Make sure PORT transfer connections originate from port 20 (ftp-data).
 18 connect_from_port_20=YES
 19 #
 20 #chown_uploads=YES
 21 #chown_username=whoever
 22 # 日志文件的路径
 23 xferlog_file=/var/log/xferlog
 24 # 日志文件的格式
 25 xferlog_std_format=YES
 26 #
 27 #idle_session_timeout=600
 28 #
 29 #data_connection_timeout=120
 30 #
 31 # It is recommended that you define on your system a unique user which the
 32 # ftp server can use as a totally isolated and unprivileged user.
 33 #nopriv_user=ftpsecure
 34 #
 35 # Enable this and the server will recognise asynchronous ABOR requests. Not
 36 # recommended for security (the code is non-trivial). Not enabling it,
 37 # however, may confuse older FTP clients.
 38 #async_abor_enable=YES
 39 #
 40 # By default the server will pretend to allow ASCII mode but in fact ignore
 41 # the request. Turn on the below options to have the server actually do ASCII
 42 # mangling on files when in ASCII mode.
 43 # Beware that on some FTP servers, ASCII support allows a denial of service
 44 # attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
 45 # predicted this attack and has always been safe, reporting the size of the
 46 # raw file.
 47 # ASCII mangling is a horrible feature of the protocol.
 48 #ascii_upload_enable=YES
 49 #ascii_download_enable=YES
 50 #
 51 # You may fully customise the login banner string:
 52 #ftpd_banner=Welcome to blah FTP service.
 53 #
 54 # You may specify a file of disallowed anonymous e-mail addresses. Apparently
 55 # useful for combatting certain DoS attacks.
 56 #deny_email_enable=YES
 57 # (default follows)
 58 #banned_email_file=/etc/vsftpd/banned_emails
 59 #
 60 # You may specify an explicit list of local users to chroot() to their home
 61 # directory. If chroot_local_user is YES, then this list becomes a list of
 62 # users to NOT chroot().
 63 # (Warning! chroot‘ing can be very dangerous. If using chroot, make sure that
 64 # the user does not have write access to the top level directory within the
 65 # chroot)
 66 chroot_local_user=YES
 67 chroot_list_enable=YES
 68 # (default follows)
 69 #chroot_list_file=/etc/vsftpd/chroot_list
 70 #
 71 # You may activate the "-R" option to the builtin ls. This is disabled by
 72 # default to avoid remote users being able to cause excessive I/O on large
 73 # sites. However, some broken FTP clients such as "ncftp" and "mirror" assume
 74 # the presence of the "-R" option, so there is a strong case for enabling it.
 75 #ls_recurse_enable=YES
 76 #
 77 # When "listen" directive is enabled, vsftpd runs in standalone mode and
 78 # listens on IPv4 sockets. This directive cannot be used in conjunction
 79 # with the listen_ipv6 directive.
 80 # 只监听ipv4的地址
 81 listen=YES
 82 #
 83 # This directive enables listening on IPv6 sockets. By default, listening
 84 # on the IPv6 "any" address (::) will accept connections from both IPv6
 85 # and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6
 86 # sockets. If you want that (perhaps because you want to listen on specific
 87 # addresses) then you must run two copies of vsftpd with two configuration
 88 # files.
 89 # Make sure, that one of the listen options is commented !!
 90 #listen_ipv6=YES
 91
 92 pam_service_name=vsftpd
 93 userlist_enable=YES
 94 tcp_wrappers=YES
 95 # 下面是自己添加的
 96 anon_root=/home/pageftp/open
 97 virtual_use_local_privs=YES
 98 guest_enable=YES
 99 guest_username=pageftp
100 # 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）
101 user_config_dir=/etc/vsftpd/vconf/
102 chroot_local_user=YES
103 allow_writeable_chroot=YES

配置虚拟用户的权限

1 sudo mkdir /etc/vsftpd/vconf/
2 touch 用户1 用户2 ……
3 vim 用户1

配置结果如下

1 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
2 ,STOR,STAT,STOU,STRU,SYST,TYPE,USER
3 write_enable=yes
4 download_enable=yes
5 anon_upload_enable=yes
6 anon_mkdir_write_enable=yes
7 anon_other_write_enable=yes
8 anon_world_readable_only=no

最后启动vsftpd服务

1 sudo systemctl enable vsftpd
2 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。
