【轉】CentOS中vsftp安裝、配置、卸載，centosvsftp
1. 安裝VSFTP1 yum -y install vsftpdView Code

 

2. 配置vsftpd.conf檔案

 

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 local_enable=YES 16 # 17 # Uncomment this to enable any form of FTP write command. 18 write_enable=YES 19 # 20 # Default umask for local users is 077. You may wish to change this to 022, 21 # if your users expect that (022 is used by most other ftpd's) 22 local_umask=022 23 # 24 # Uncomment this to allow the anonymous FTP user to upload files. This only 25 # has an effect if the above global write enable is activated. Also, you will 26 # obviously need to create a directory writable by the FTP user. 27 #anon_upload_enable=YES 28 # 29 # Uncomment this if you want the anonymous FTP user to be able to create 30 # new directories. 31 #anon_mkdir_write_enable=YES 32 # 33 # Activate directory messages - messages given to remote users when they 34 # go into a certain directory. 35 dirmessage_enable=YES 36 # 37 # The target log file can be vsftpd_log_file or xferlog_file. 38 # This depends on setting xferlog_std_format parameter 39 xferlog_enable=YES 40 # 41 # Make sure PORT transfer connections originate from port 20 (ftp-data). 42 connect_from_port_20=YES 43 # 44 # If you want, you can arrange for uploaded anonymous files to be owned by 45 # a different user. Note! Using "root" for uploaded files is not 46 # recommended! 47 #chown_uploads=YES 48 49 #chown_username=whoever 50 # 51 # The name of log file when xferlog_enable=YES and xferlog_std_format=YES 52 # WARNING - changing this filename affects /etc/logrotate.d/vsftpd.log 53 #xferlog_file=/var/log/xferlog 54 # 55 # Switches between logging into vsftpd_log_file and xferlog_file files. 56 # NO writes to vsftpd_log_file, YES to xferlog_file 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. 77 # Beware that on some FTP servers, ASCII support allows a denial of service 78 # attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd 79 # predicted this attack and has always been safe, reporting the size of the 80 # raw file. 81 # ASCII mangling is a horrible feature of the protocol. 82 ascii_upload_enable=YES 83 ascii_download_enable=YES 84 85 # 86 # You may fully customise the login banner string: 87 ftpd_banner=Welcome to lightnear 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 chroot_local_user=YES 99 #chroot_list_enable=YES 100 # (default follows) 101 #chroot_list_file=/etc/vsftpd/chroot_list 102 # 103 # You may activate the "-R" option to the builtin ls. This is disabled by 104 # default to avoid remote users being able to cause excessive I/O on large 105 # sites. However, some broken FTP clients such as "ncftp" and "mirror" assume 106 # the presence of the "-R" option, so there is a strong case for enabling it. 107 ls_recurse_enable=YES108 # 109 # When "listen" directive is enabled, vsftpd runs in standalone mode and 110 # listens on IPv4 sockets. This directive cannot be used in conjunction 111 # with the listen_ipv6 directive. 112 listen=YES 113 # 114 # This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6 115 # sockets, you must run two copies of vsftpd with two configuration files. 116 # Make sure, that one of the listen options is commented !! 117 #listen_ipv6=YES118 119 pam_service_name=vsftpd 120 userlist_enable=YES 121 userlist_deny=NO 122 local_root=/var/public_root 123 tcp_wrappers=YES124 use_localtime=YESView Code

 

3. 增加FTP帳戶

   這裡設定的賬戶名為“objectyan”,密碼為“objectyan”

1 [root@localhost ~]# useradd objectyan -s /sbin/nologin2 [root@localhost ~]# passwd objectyanView Code

 

4. 編輯user_list檔案，允許objectyan使用者訪問FTP 1 [root@localhost ~]# vi /etc/vsftpd/user_list 2 3 # vsftpd userlist 4 # If userlist_deny=NO, only allow users in this file 5 # If userlist_deny=YES (default), never allow users in this file, and 6 # do not even prompt for a password. 7 # Note that the default vsftpd pam config also checks /etc/vsftpd/ftpusers 8 # for users that are denied. 9 root10 bin11 daemon12 adm13 lp14 sync15 shutdown16 halt17 mail18 news19 uucp20 operator21 games22 nobody23 objectyanView Code 5. 建立我們的根目錄，並設定存取權限1 [root@localhost ~]# mkdir /var/public_root2 [root@localhost ~]# chown -R objectyan /var/public_root3 [root@localhost ~]# chmod -R 755 /var/public_rootView Code6. 開啟vsftpd服務1 [root@localhost ~]# service vsftpd startView Code7.預設開啟vsftp服務

 

1 [root@localhost var]# chkconfig vsftpd onView Code

 

centos 卸載vsftpd方法

  　　如果伺服器上安裝了vsftpd，配置出錯需要卸載vsftpd

 

1 [root@localhost ~]# rpm -aq vsftpdView Code

 

　　vsftpd-2.0.5-16.el5_5.1 #此處是尋找vsftpd的返回結果

1 [root@localhost ~]# rpm -e vsftpd-2.0.5-16.el5_5.1View Code

　　#用rpm -e 尋找結果 進行刪除就ok了。

　　warning: /etc/vsftpd/ftpusers saved as /etc/vsftpd/ftpusers.rpmsave #刪除時將備份vsftp的使用者列表檔案。
