redhat vsftp配置以及服务自动启动设置



redhat vsftp配置以及服务自动启动设置
 
我们这里使用的vsftpd,基本配置
  www.2cto.com  
[root@ftp ~]# cat /etc/vsftpd/vsftpd.conf 
# 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 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
chroot_local_user=YES
pam_service_name=vsftpd
userlist_enable=YES
tcp_wrappers=YES
启动ftp服务
service vsftpd restart
ps -ef | grep vsftpd
  www.2cto.com  
#查看一下ftp服务是否是自启动的
chkconfig --list vsftpd
显示信息如下
vsftpd          0:off   1:off   2:off   3:off   4:off   5:off    6:off
#运行如下命令
chkconfig --level 3 vsftpd on
chkconfig --level 5 vsftpd on
 
#查看一下ftp服务是否是自启动的
chkconfig --list vsftpd
显示信息如下
vsftpd          0:off   1:off   2:off   3:on   4:off   5:on    6:off
注意一下3和5的状态如果都是on就是对的。
 
很久没搞过了,网上的看了看总结一下
 
http://www.2cto.com/os/201210/161239.html

root@localhost ~]# chkconfig --list     显示开机可以自动启动的服务
[root@localhost ~]# chkconfig --add *** 添加开机自动启动***服务
[root@localhost ~]# chkconfig --del ***   删除开机自动启动***服务
 
 
[root@localhost ~]# setup   可以在shell图形终端里面配置的命令,去service里选择
 
 
[root@localhost ~]# ntsysv   在shell终端图形配置开机启动服务命令,选项没上面那个多
 
setup 、rc.local 和chkconfig三种方式都可以设置
 
第一种)
输入#setup指令进入系统服务菜单,选择你想启动的服务比如httpd,然后重起机器或者/etc/rc.d./init.d/httpd 
  start 
 
第二种)
把启动命令放到/etc/rc.d/rc.local文件里这样就可以每次启动的时候自动启动服务了,例如对于apache,编译好apache后会在安装目录的bin下生成apachectl文件,这是个启动脚本,我们只需要把这个命令加到rc.local里就可以了
 
(suse没有rc.local。SUSE是可以这么定义自己的脚本的,如果希望在切换运行级之前和之后运行自己的脚本,那么可以分别创建:
/etc/init.d/before.local
/etc/init.d/after.local)
echo /usr/local/apache/bin/apachectl>> /etc/rc.d/rc.local,
设置服务自动启动的方式是在rc.local里还可以加入类似以下的一些脚本:
  www.2cto.com  
#sshd
/usr/local/sbin/sshd
 
#proftpd
/usr/local/sbin/proftpd
 
#apache
/home/apache/bin/apachectl start
 
#mysql
/home/mysql/bin/safe_mysqld --port=3306 &
 
#start oracle8i listener first
su - oracle -c 'lsnrctl start'
 
#start oracle8i
su - oracle -c 'dbstart'
 
第三种)
通过chkconfig指令.
 
使用chkconfig命令来把某项服务加到系统的各项运行级别中,步骤如下,
1 创建启动脚本.
  对于apache,mysql,ssh这样的软件都是自己带的,我们只要稍微修改一下使之支持chkconfig就可以了
 
2 修改脚本
我们需要在脚本的前面加上一下2行,才能支持chkconfig命令
# chkconfig: 2345 08 92
#
# description: Automates a packet filtering firewall withipchains.
#
chkconfig:后面定义的使启动服务的运行级别(例子中使2345启动改服务),以及关闭和启动服务的顺序,(上例中关闭服务的顺序使8,启动的顺序使92)
descriptions:对改服务的描述(上例中是ipchains包过滤),你可以换成自己想要的
 
修改好之后执行
cp 你的脚本 /etc/rc.d/init.d/脚本名
chmod 700 /etc/rc.d/init.d/脚本名
chkconfig --add 脚本名
 
例如:
将其加入Linux启动过程,仅在level 3, level 5级别下运行
[root@Tester init.d]/sbin/chkconfig --add apache-httpd
[root@Tester init.d]/sbin/chkconfig --level 35 apache-httpdon
之后就可以了,以后每次重新启动服务器都会自动启动和关闭我们的服务了
