CentOS 64位 搭建FTP服务器过程----自己成功后的总结
1.查看是否安装vsftpd
rpm -qa|grep vsftpd
2.没有的话,安装 yum -y install vsftpd
卸载的话 rpm -e 安装包名称
3.修改配置文件
# 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=NO # # 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=NO # # 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=ftptesting # # 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=NO chroot_list_enable=YES # (default follows) chroot_list_file=/etc/vsftpd/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 #my add background=YES guest_enable=YES guest_username=ftptesting user_config_dir=/etc/vsftpd/user_config max_clients=100 max_per_ip=20 pasv_enable=YES pasv_min_port=6000 pasv_max_port=7000
主要修改的地方为：
//不匿名登陆
anonymous_enable=NO
//本地账户
nopriv_user=ftptesting
chroot_local_user=NO
chroot_list_enable=YES
//本地账户映射文件
chroot_list_file=/etc/vsftpd/vsftpd.chroot_list
//本地用户
guest_username=ftptesting
//虚拟用户配置信息所在位置
user_config_dir=/etc/vsftpd/user_config
3.创建本地用户ftptesting 以及加入到虚拟用户映射文件
useradd ftptesting
vi /etc/vsftpd/vsftpd.chroot_list
文件内写入:
ftptesting
//该文件为手动建立，每一行代表一个欲将虚拟用户映射到本地账户的名称
4.创建用户账户密码文件passwd.file
格式为第一行为用户名第二行密码以此类推
vi /etc/vsftpd/passwd.file
ftpuser
123456
5.生成虚拟用户认证文件
db_load -T -t hash -f /etc/vsftpd/passwd.file /etc/vsftpd/ftpuser_passwd.db
6.创建用户配置文件
mkdir /etc/vsftpd/user_config
vi /etc/vsftpd/user_config/ftpuser
local_root=/home/test //该路径对应的目录必须存在，下一步创建 write_enable=YES anon_umask=022 anon_world_readable_only=NO anon_upload_enable=YES anon_mkdir_write_enable=YES anon_other_write_enable=YES
7.虚拟用户访问目录必须存在，或者自己创建
mkdir /home/test/ss
本文中ftpuser虚拟用户是被映射到ftptesting系统帐户的，所以 ftptesting系统帐户必须拥有对ftpuser 的 FTP 主目录/home/test的读/写权限
chown -R ftptesting:ftptesting /home/test/
8.修改pam认证模板文件
修改前需要先查看自己系统是32位还是64位，命令为:getconf LONG_BIT
编辑文件 vi /etc/pam.d/vsftpd
注释掉说有内容
增加一下内容
32位系统增加以下两句：
auth required pam_userdb.so db=/etc/vsftpd/ftpuser_passwd
account required pam_userdb.so db=/etc/vsftpd/ftpuser_passwd
64位系统增加以下两句：
auth required /lib64/security/pam_userdb.so db=/etc/vsftpd/ftpuser_passwd
account required /lib64/security/pam_userdb.so db=/etc/vsftpd/ftpuser_passwd
增加的文件名为第五步生成的认证文件的文件名 .db结尾的
9.关闭防火墙
service iptables stop
10.关闭selinux
setenforce 0 //临时关闭，重起系统失效
或者修改selinux配置关闭selinux
vi /etc/selinux/config
SELINUX=disable
11.启动vsftpd服务
service vsftpd start
或者重启
service vsftpd restart
12.到此恭喜你配置成功！可以访问了
连接ftp 第四步创建的用户名为ftpuser 密码123456
