[1]CentOS 5.4 pptp + freeradius2 +mysql +daloradius 完美整合（图文并茂）

只写操作的过程，其它没有相应的说明！！

CentOS 5.4下配置pptpd服务器已经在其它篇章中有描述，这里为文章的链接入口<< CentOS release 5.4 (Final) 配置PPTP VPN服务器（初步）>>

！！本文也是在此基础上做的改变，请先参照上述文章，完成PPTP VPN服务器的构建，再做如下步骤！！

一、安装相关配置包

1、安装httpd、mysql及php相关包

[root@localhost ~]# yum -y install httpd httpd-devel mysql mysql-server mysql-devel
[root@localhost ~]# yum -y install php php-devel php-mysql php-common php-gd php-mbstring php-mcry

2、配置httpd服务：

[root@localhost ~]# netstat -ant |grep 80
[root@localhost ~]# /etc/init.d/httpd start
Starting httpd:                                            [  OK  ]
[root@localhost ~]# vi /etc/sysconfig/iptables
[root@localhost ~]# grep 80 /etc/sysconfig/iptables
-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 80 -j ACCEPT  #增加此行
[root@localhost ~]# /etc/init.d/iptables restart
Flushing firewall rules:                                   [  OK  ]
Setting chains to policy ACCEPT: filter nat                [  OK  ]
Unloading iptables modules:                                [  OK  ]
Applying iptables firewall rules:                          [  OK  ]
Loading additional iptables modules: ip_conntrack_netbios_n[  OK  ]
[root@localhost ~]# chkconfig httpd --list
httpd           0:off   1:off   2:off   3:off   4:off   5:off   6:off
[root@localhost ~]# chkconfig httpd on  #设置httpd自动启动
[root@localhost ~]# chkconfig httpd --list
httpd           0:off   1:off   2:on    3:on    4:on    5:on    6:off
[root@localhost ~]# netstat -ant |grep 80
tcp        0      0 :::80                       :::*                        LISTEN

3、启动mysql数据库：

[root@localhost ~]# /etc/init.d/mysqld start
Initializing MySQL database:  Installing MySQL system tables...
OK
Filling help tables...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h localhost.localdomain password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

See the manual for more instructions.

You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/bin/mysqlbug script!

The latest information about MySQL is available on the web at
http://www.mysql.com
Support MySQL by buying support/licenses at http://shop.mysql.com
                                                           [  OK  ]
Starting mysqld:                                           [  OK  ]

4、设置数据库密码;

[root@localhost ~]# mysqladmin -u root password 'leekwen'

5、安装Freeradius2相关包

[root@localhost ~]# yum install -y freeradius2 freeradius2-mysql freeradius2-utils

6、启动radius进程，调试模式：

[root@localhost ~]# radiusd -X
FreeRADIUS Version 2.1.12, for host i386-redhat-linux-gnu, built on Jan  9 2013 at 05:02:57
Copyright (C) 1999-2009 The FreeRADIUS server project and contributors.
 ... adding new socket proxy address * port 51738
Listening on authentication address * port 1812
Listening on accounting address * port 1813
Listening on command file /var/run/radiusd/radiusd.sock
Listening on authentication address 127.0.0.1 port 18120 as server inner-tunnel
Listening on proxy address * port 1814
Ready to process requests.

7、开启另外一个终端进行测试，如图：

8、如果结果与上图不同，请临时关闭防火墙后，临时关闭防火墙命令如下：

[root@localhost ~]# iptables -F

重新运行测试命令：

[root@localhost ~]# radtest steve testing localhost 1812 testing123

##############
#  ！！error ！！  #
##############
Failed binding to authentication address * port 1812: Address already in use
/etc/raddb/radiusd.conf[240]: Error binding to port for 0.0.0.0 port 1812

请先用 lsof 命令查看，再用 killall -9 radiusd命令结束后，重新开启服务后，在进行测试！

二、下载ppp源码文件，集成ppp client:

1、下载源码：

[root@localhost ~]# wget ftp://ftp.samba.org/pub/ppp/ppp-2.4.4.tar.gz
--2013-07-01 18:33:36--  ftp://ftp.samba.org/pub/ppp/ppp-2.4.4.tar.gz
           => `ppp-2.4.4.tar.gz'

2013-07-01 18:33:45 (127 KB/s) - `ppp-2.4.4.tar.gz' saved [688763]

2、解压并做相关配置

[root@localhost ~]# tar zxf ppp-2.4.4.tar.gz
[root@localhost ~]# cp -R ppp-2.4.4/pppd/plugins/radius/etc/ /etc/radiusclient
[root@localhost ~]# cp /etc/radiusclient/radiusclient.conf /etc/radiusclient/radiusclient.conf.bak
[root@localhost ~]# vi /etc/radiusclient/radiusclient.conf
行号                修改前的配置文件                                修改后的配置文件
25   issue         /usr/local/etc/radiusclient/issue      修改为：issue        /etc/radiusclient/issue
46   servers      /usr/local/etc/radiusclient/servers     修改为：servers     /etc/radiusclient/servers
50   dictionary  /usr/local/etc/radiusclient/dictionary   修改为：dictionary /etc/radiusclient/dictionary
61   mapfile    /usr/local/etc/radiusclient/port-id-map   修改为：mapfile   /etc/radiusclient/port-id-map

说明：修改相关配置文件的路径，确保radiusclient.conf这个文件中radiusclient相关的路径都是“/etc/radiusclient”开头的.

3、配置字典文件：

[root@localhost ~]# ls -l /etc/radiusclient/dictionary*
-rw-r--r-- 1 root root  7656 Jul  1 18:34 /etc/radiusclient/dictionary
-rw-r--r-- 1 root root 12295 Jul  1 18:34 /etc/radiusclient/dictionary.ascend
-rw-r--r-- 1 root root  1395 Jul  1 18:34 /etc/radiusclient/dictionary.compat
-rw-r--r-- 1 root root   599 Jul  1 18:34 /etc/radiusclient/dictionary.merit
-rw-r--r-- 1 root root  2649 Jul  1 18:34 /etc/radiusclient/dictionary.microsoft
[root@localhost ~]# vi /etc/radiusclient/dictionary
行号          文件内容
253  INCLUDE /etc/radiusclient/dictionary.microsoft
254  INCLUDE /etc/radiusclient/dictionary.merit    #增加此行
255  INCLUDE /etc/radiusclient/dictionary.ascend   #增加此行
256  INCLUDE /etc/radiusclient/dictionary.compat   #增加此行

4、在pptpd服务中添加freeradius插件：

[2]SharePoint Infopath表单服务-PowerShell

1. 激活可浏览的表单模板

Set-SPInfoPathFormsService -AllowUserFormBrowserEnabling $true
-AllowUserFormBrowserRendering $true

2. 设置数据连接超时

Set-SPInfoPathFormsService –DefaultDataConnectionTimeout 15
–MaxDataConnectionTimeout 25

3. 设置数据连接响应大小

Set-SPInfoPathFormsService –MaxDataConnectionResponseSize 3

4. 修改认证设置

Set-SPInfoPathFormsService –RequireSslForDataConnections $true –
AllowEmbeddedSqlForDataConnection $true –
AllowUdcAuthenticationForDataConnections $true –
AllowUserFormCrossDomainDataConnections $true

RequireSslForDataConnections：True为表单使用HTTP认证时需要SSL加密。

AllowEmbeddedSqlForDataConnection：当有包含用户名和密码的数据库连接信息的数据连接文件时，设置为True。

AllowUdcAuthenticationForDataConnections：是否允许自定义表单通过数据连接文件访问数据源。

AllowUserFormCrossDomainDataConnections：当表单需要访问与SharePoint不同的数据源时，设置为True。

5. 设置会话状态

Set-SPInfoPathFormsService –MaxPostbacksPerSession 110 –
ActiveSessionTimeout 720

6. 启用视图状态

Set-SPInfoPathFormsService –AllowViewState $true –ViewStateThreshold
40961

7. 验证并上传表单模板

Test-SPInfoPathFormTemplate
-Path "<<full path to InfoPath form template>>" 
Install-SPInfoPathFormTemplate-Path "<<full path to InfoPath form template>>"

8. 一次上传多个表单模板

"<<path of form 1>>" , "<<path of form 2>" , "<<path of form 3>>" |
Install-SPInfoPathFormTemplate

9. 激活/反激活网站集的表单模板

Enable-SPInfoPathFormTemplate
-Identity "<<name of form template>>"
-Site "<<URL of Site Collection>>" 

Disable-SPInfoPathFormTemplate
-Identity "<<name of form template>>"
-Site "<<URL of Site Collection>>"

10. 从InfoPath表单服务移除一个表单

Uninstall-SPInfoPathFormTemplate -Identity "<<name of form template>>"

11. 禁用InfoPath表单服务中的某一表单

Stop-SPInfoPathFormTemplate -Identity "<<name of form template>>"

12. 启用Web服务代理

Set-SPInfoPathWebServiceProxy -Identity "<<URL of web application>>"
-AllowWebServiceProxy $true

Set-SPInfoPathWebServiceProxy -Identity "<<URL of web application>>"
-AllowForUserForms $true

[3]Linux终端中使用上一命令减少键盘输入

减少键盘输入，可以大大提高程序员的工作效率，快捷键的使用就是一个很好的例子。程序员经常使用终端。那么在终端上有没有类似的“快捷键”可以提高我们的效率呢？程序员的工作往往是前后相关连的。所以，本文将演示如何使用上一条命令提高工作效率的。

1.使用上一条命令的所有参数

方法：!*

例子：如果我对hello.txt和bye.txt进行了编辑，然后希望使用git add添加这两个文件。就可以使用：git add !*

2.使用上一条命令的最后一个参数

方法：!$

           ALT + .

           ESC + .

其中后面两种方法，terminal中会自动补全

3.使用上一条命令中除了最后一个参数的部分

方法：!-:

例子：个人认为这个比较有用，因为有些命令中间会输入一大堆选项，最后一个才是实际发挥作用的对象，如果再次输入选项，会显得麻烦。

4.使用上一条命令中任意一个部份

方法：ALT + <num> + .

            其中num表示的上一条命令中的第几部分，从0开始，对于ls -shld hello.txt。ALT +０＋. 就是ls。1就是-shld

5.替换上一条命令中的一个部份

方法：将foo替换为bar

            ^foo^bar 　　　仅替换地一个

　　　!!:gs/foo/bar   　替换所有

6.上一条命令

方法：！！

最后：推荐一个网站，可以这样来学习，如果遇到一条需要输入的命令，让你觉得需要键盘输入过多，或者说你猜想可能有更好的、更快捷的方式时，不妨到这个网站上来搜一下，这样慢慢积累，加以时日，应该还是有一定的收获: commandlinefu.com
