1.安装和卸载vsftpd 1.1安装vsftpd
a．rpm -qa|grep vsftpd 检查centos是否已经安装了vsftpd
b．cd到光盘的Centos目录下运行 rpm –ivh vsftpd*. Rpm安装vsftpd
备注（当centos连接internet时使用yum install vsftpd安装）
[root@localhost ~]# yum install vsftpd

1.2．卸载vsftpd
a．rpm -qa|grep vsftpd 检查centos是否已经安装了vsftpd
b.运行 yum remove vsftpd卸载 vsftpd
2.检查并启动vsftpd
A．使用命令 rpm –qa|grep vsftpd 检测是否安装了vsftpd
B.使用命令service vsftpd status 检查 vsftpd服务的启动状态
C. 使用命令 sevice vsftpd start 启动vsftpd服务
3.解决ftp客户端中文文件名乱码问题
Centos ftp的主目录中文显示正常
而客户端访问时中文文件名乱码
解决方法
使用vi编辑器打开/etc/sysconfig/目录下的i18n，把内容改为LANG="zh_CN.GB2312",然后按esc键最后 输入：wq保存，然后reboot一下centos
最后客户端访问结果如下
4.使用匿名访问ftp站点，在ftp主目录下新建upload使匿名用户可以上传 下载 运行
a. 在ftp的家目录创建upload文件夹
b. 并使用chmod 777 /var/ftp/upload将upload设置为所有用户都有读、写、执行权限
c. 将vsftpd.cnf文件改动如下
# 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 anon_other_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_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 whith 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 5.更改ftp用户默认的家目录位置 a.使用mkdir /ftpmain建立ftpmain b.使用chmod 755 /ftpmain修改ftpmain的访问权限 c.使用vi/etc/password更改用户ftp的家目录 d.保存后使用service vsftpd restart重启vsftpd服务 
6.定制访问vsftpd时的欢迎信息 a.打开/etc/vsftpd/vsftpd.conf b.添加dirmessage_enable=YES
message_file=.message c．把写好欢迎信息的.message文件放到用户的家目录下，并使用chmod 755 /ftpmain/.message设置一下.message的访问权限 
7.使用用户名和密码访问ftp
a.修改vsftpd.conf文件 anonymous_enable=no b.使用useradd -d /ftpmain -g ftp -s /sbin/nologin testuser新建testuser用户，并设置密码
