一、安装vsftpd
1.1 检查系统是否已经安装过vsftpd了
1 [root@localhost /]# rpm -aq vsftpd
如果返回结果显示：
1 vsftpd-3.0.2-21.el7.x86_64
#此处是查找vsftpd的返回结果
如果提示已安装，但是你之前配置错了，不知道怎么搞，那么进行1.2步骤
1.2 卸载系统目前的vsftpd
停止vsftpd运行：
1 [root@localhost /]# /sbin/service vsftpd stop
卸载vsftpd
1 [root@localhost /]# rpm -e vsftpd-3.0.2-21.el7.x86_64
此时系统会返回以下信息
1 warning: /etc/vsftpd/vsftpd.conf saved as /etc/vsftpd/vsftpd.conf.rpmsave
接下来直接把上步（系统返回的提示信息）没卸载干净的东西删除
1 rm -rf /etc/vsftpd/vsftpd.conf.rpmsave
1.3 验证vsftpd是否卸载干净
1 [root@localhost /]# /sbin/service vsftpd stop 2 Redirecting to /bin/systemctl stop vsftpd.service 3 Failed to stop vsftpd.service: Unit vsftpd.service not loaded. #找不到vsftpd 4 [root@localhost /]# /sbin/service vsftpd start 5 Redirecting to /bin/systemctl start vsftpd.service 6 Failed to start vsftpd.service: Unit not found. #找不到vsftpd
1.4 安装vsftpd
1 [root@localhost /]# yum -y install vsftpd
1.5 启动vsftpd
1 [root@localhost home]# systemctl start vsftpd.service
或者
1 [root@localhost home]# service vsftpd restart
1.6 开放端口
1 [root@localhost /]# firewall-cmd --zone=public --add-port=21/tcp --permanent 2 [root@localhost /]# firewall-cmd --reload
注意ftp是21端口，sftp是22端口，也可以自己配置，但是到这一步，我们只需要了解就行，我们接着配置吧
二、分配用户
2.1 在你的linux上新建一个用户，只用来ftp不用来登录服务器
1 useradd Marry -s /sbin/nologin -d /var/ftp
上面的意思是，新建一个不用来登录服务器的用户，Marry，并设置他的ftp空间为/var/ftp 目录下。
接下来配置用户Marry的密码：
1 passwd Marry #给Marry用户设置密码
接下来按照提示输入你的密码就好
回过头来，说明下上面两个命令的意思
1 /* useradd 使用到3个参数：用户名，-s，-d，三个参数位置可以变动 2 3 Marry是用户名 4 5 -d 后面跟的是我们要给予Marry的家目录 6 7 */
2.2 设置上面新建用户对文件夹的操作权限
修改/var/ftp的权限为不可写
1 [root@localhost vsftpd]# chmod a-w /var/ftp/
这是因为我们在上面将/home/ftpuser/taotao文件的权限改为不可写了，那么我们在这个目录下创建一个images文件夹，用来上传文件。并将权限赋值给 ftpuser 用户
三、vsftpd配置
3.1 限制系统用户锁定在/home/ftpuser目录
如果设置为
chroot_local_user＝YES chroot_list_enable=YES(这行可以没有, 也可以有) chroot_list_file=/etc/vsftpd.chroot_list 那么, 凡是加在文件vsftpd.chroot_list中的用户都是不受限止的用户 即, 可以浏览其主目录的上级目录. 所以, 如果不希望某用户能够浏览其主目录上级目录中的内容,可以如上设置, 然后在 文件vsftpd.chroot_list中不添加该用户即可(此时, 在该文件中的用户都是可以浏览其主目录之外的目录的). 或者, 设置如下 chroot_local_user＝NO chroot_list_enable=YES(这行必须要有, 否则文件vsftpd.chroot_list不会起作用) chroot_list_file=/etc/vsftpd.chroot_list 然后把所有不希望有这种浏览其主目录之上的各目录权限的用户添加到文件vsftpd.chroot_list(此时, 在该文件中的用户都是不可以浏览其主目录之外的目录的) 中即可(一行一个用户名).
[root@localhost vsftpd]# vim /etc/vsftpd/vsftpd.conf
这里有两种方案，我采用第二种，配置如下：
chroot_local_user＝NO chroot_list_enable=YES #(这行必须要有, 否则文件vsftpd.chroot_list不会起作用) chroot_list_file=/etc/vsftpd/chroot_list
默认chroot_list是不存在的
[root@localhost vsftpd]# vim /etc/vsftpd/chroot_list
然后加入 ftpuser ，表示只有ftpuser不能访问上级目录，重启vsftpd。
3.2 开启PASV（被动模式）
在 /etc/vsftpd/vsftpd.conf 的最下面加入
1 pasv_enable=YES 2 pasv_min_port=30000 3 pasv_max_port=30999
（提示：如果你处于被动模式，发现登陆上了但是，无法上下载数据，并且提示，无法显示，可能是你防火墙的端口没开，还有你的端口
pasv_min_port是最小的端口，
pasv_max_port是最大的端口，不要写错了，还有，端口开了，要重启防火墙才能生效
）
并且在userlist_enable=YES文件后面添加
1 userlist_deny=NO 2 userlist_file=/etc/vsftpd/user_list
开启防火墙：
[root@localhost taotao]# firewall-cmd --zone=public --add-port=30000-30999/tcp --permanent [root@localhost taotao]# firewall-cmd --reload
3.3 添加用户到
添加用户到chroot_list，等几个文件中
四、最终的vsftpd.conf 文件的配置内容如下：
sz /etc/vsftpd/vsftpd.conf
1 # Example config file /etc/vsftpd/vsftpd.conf 2 # 3 # The default compiled in settings are fairly paranoid. This sample file 4 # loosens things up a bit, to make the ftp daemon more usable. 5 # Please see vsftpd.conf.5 for all compiled in defaults. 6 # 7 # READ THIS: This example file is NOT an exhaustive list of vsftpd options. 8 # Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's 9 # capabilities. 10 # 11 # Allow anonymous FTP? (Beware - allowed by default if you comment this out). 12 anonymous_enable=YES 13 # 14 # Uncomment this to allow local users to log in. 15 # When SELinux is enforcing check for SE bool ftp_home_dir 16 local_enable=YES 17 # 18 # Uncomment this to enable any form of FTP write command. 19 write_enable=YES 20 # 21 # Default umask for local users is 077. You may wish to change this to 022, 22 # if your users expect that (022 is used by most other ftpd's) 23 local_umask=022 24 # 25 # Uncomment this to allow the anonymous FTP user to upload files. This only 26 # has an effect if the above global write enable is activated. Also, you will 27 # obviously need to create a directory writable by the FTP user. 28 # When SELinux is enforcing check for SE bool allow_ftpd_anon_write, allow_ftpd_full_access 29 #anon_upload_enable=YES 30 # 31 # Uncomment this if you want the anonymous FTP user to be able to create 32 # new directories. 33 #anon_mkdir_write_enable=YES 34 # 35 # Activate directory messages - messages given to remote users when they 36 # go into a certain directory. 37 dirmessage_enable=YES 38 # 39 # Activate logging of uploads/downloads. 40 xferlog_enable=YES 41 # 42 # Make sure PORT transfer connections originate from port 20 (ftp-data). 43 connect_from_port_20=YES 44 # 45 # If you want, you can arrange for uploaded anonymous files to be owned by 46 # a different user.

The default is shown 52 # below. 53 #xferlog_file=/var/log/xferlog 54 # 55 # If you want, you can have your log file in standard ftpd xferlog format. 56 # Note that the default log file location is /var/log/xferlog in this case. 57 xferlog_std_format=YES 58 # 59 # You may change the default value for timing out an idle session. 60 #idle_session_timeout=600 61 # 62 # You may change the default value for timing out a data connection. 63 data_connection_timeout=120 64 # 65 # It is recommended that you define on your system a unique user which the 66 # ftp server can use as a totally isolated and unprivileged user. 67 #nopriv_user=ftpsecure 68 # 69 # Enable this and the server will recognise asynchronous ABOR requests. Not 70 # recommended for security (the code is non-trivial). Not enabling it, 71 # however, may confuse older FTP clients. 72 #async_abor_enable=YES 73 # 74 # By default the server will pretend to allow ASCII mode but in fact ignore 75 # the request. Turn on the below options to have the server actually do ASCII 76 # mangling on files when in ASCII mode. The vsftpd.conf(5) man page explains 77 # the behaviour when these options are disabled. 78 # Beware that on some FTP servers, ASCII support allows a denial of service 79 # attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd 80 # predicted this attack and has always been safe, reporting the size of the 81 # raw file. 82 # ASCII mangling is a horrible feature of the protocol. 83 ascii_upload_enable=YES 84 ascii_download_enable=YES 85 # 86 # You may fully customise the login banner string: 87 ftpd_banner=Welcome to blah FTP service. 88 # 89 # You may specify a file of disallowed anonymous e-mail addresses. Apparently 90 # useful for combatting certain DoS attacks. 91 #deny_email_enable=YES 92 # (default follows) 93 #banned_email_file=/etc/vsftpd/banned_emails 94 # 95 # You may specify an explicit list of local users to chroot() to their home 96 # directory. If chroot_local_user is YES, then this list becomes a list of 97 # users to NOT chroot(). 98 # (Warning! chroot'ing can be very dangerous. If using chroot, make sure that 99 # the user does not have write access to the top level directory within the 100 # chroot) 101 chroot_local_user=YES 102 chroot_list_enable=YES 103 # (default follows) 104 chroot_list_file=/etc/vsftpd/chroot_list 105 # 106 # You may activate the "-R" option to the builtin ls. This is disabled by 107 # default to avoid remote users being able to cause excessive I/O on large 108 # sites. However, some broken FTP clients such as "ncftp" and "mirror" assume 109 # the presence of the "-R" option, so there is a strong case for enabling it. 110 ls_recurse_enable=YES 111 # 112 # When "listen" directive is enabled, vsftpd runs in standalone mode and 113 # listens on IPv4 sockets. This directive cannot be used in conjunction 114 # with the listen_ipv6 directive. 115 listen=YES 116 # 117 # This directive enables listening on IPv6 sockets. By default, listening 118 # on the IPv6 "any" address (::) will accept connections from both IPv6 119 # and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6 120 # sockets. If you want that (perhaps because you want to listen on specific 121 # addresses) then you must run two copies of vsftpd with two configuration 122 # files. 123 # Make sure, that one of the listen options is commented !! 124 #listen_ipv6=YES 125 126 pam_service_name=vsftpd 127 userlist_enable=YES 128 userlist_deny=NO 129 local_root=/var/public_home 130 tcp_wrappers=YES 131 use_localtime=YES 132 allow_writeable_chroot=YES 133 pasv_enable=YES 134 pasv_min_port=7666 135 pasv_max_port=7700
