# 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=YES
#
# 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
#
# Activate logging of uploads/downloads.
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
#
# You may override where the log file goes if you like. The default is shown
# below.
#xferlog_file=/var/log/vsftpd.log
#
# If you want, you can have your log file in standard ftpd xferlog format
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 my 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=YES
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
#
# You may activate the "-R" option to the builtin ls. This is disabled by

# 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 !!

一个ftp用户
3>
1.添加虚拟用户
useradd kaqi -r -m -g ftp -d /var/www/html/ftpsite -s /sbin/nologin
passwd kaqi
2.
chown kaqi /var/www/html/ftpsite
chmod 777 /var/www/html/ftpsite
4> 重启vsftpd
命令：service vsftpd restart
5>这个地方很重要
安装好apache和vsftpd后，发现都只能访问默认根目录下的文件。
查找资料后发现时selinux的问题，所以需要关闭这个服务
vi /etc/sysconfig/selinux
SELINUX=enforcing --> SELINUX=disabled
重启后生效 重启命令reboot
--------------------------------------------------------------------------------------------------------------------------------------------------------
扩展知识：
linux调用服务的命令:
ntsysv
----------------------------------------------------------------------------------------------------------------------------------------------------------------
安装mysql命令：yum install mysql-server
//第一次安装mysql时
1. mysql -u root;
2. use mysql;
3.设置密码 update user set password =passwror('新密码') where user ="root";
4、flush privileges; //一定需要此命令，要不然重启linux后，密码会丢失
------------------------------------------------------------------------------------------------------------------------------------------------
etc/httpd/conf //http.conf配置所在目录
http.conf 需要配置的地方：
NameVirtualHost *:80 //打开共公80端口
AddDefaultCharset GBK //针对gb2312网页，乱码情况
//配置虚拟目录
<VirtualHost *:80>
DocumentRoot "/var/www/html/shanghaizx/upload"
ServerName www.85zx.com
ServerAlias 85.whzx120.com
ErrorLog logs/www.85zx120.com-error_log
CustomLog logs/www.85x120.com-access_log common
</VirtualHost>
var/log/httpd //保存日志文件所在目录
----------------------------------------------------------------------------------------------------------------------------------------------
dns的配置：
路径：/etc/resolv.conf
search localdomain
nameserver 202.103.24.68
----------------------------------------------------------------------------------------------------------------------------------------------
linux中日志轮询的服务是logrotate，主配置文件是/etc/logrotate.conf和/etc/logrotate.d中的文件
如何将某日志文件按照文件大小轮转呢？
可以通过修改/etc/logrotate.d/httpd配置文件来解决。修改之后如下（其中添加了size=10M，rotate 4)
/var/log/httpd/*log {
size=10M //增加
rotate 4 //增加
missingok
notifempty
sharedscripts
postrotate
/bin/kill -HUP `cat /var/run/httpd.pid 2>/dev/null` 2> /dev/null || true
endscript
}
