怎样在windows下配置ffmpeg-php[转载]
2012-1-30 18:31 Monday  

在网上搜索了很多关于ffmpeg－php的文章。大部分都是在linux下配置的文章。介绍window配置的内容相当的少，通过自己努力终于在windows下配置成功。特写下文章希望对大家做视频开发有用。

首先介绍下我使用的集成环境wamp。

PHP: php5.2.6

Apache: apache2.2.8

1.下载ffmpeg－php：http://sergey89.ru/files/ffmpeg-php-win32-all.zip

2. 解压ffmpeg-php-win32-all.zip 后有下面几个文件：

     avcodec-51.dll

     avformat-51.dll

     avutil-49.dll

     php_ffmpeg.dll

     pthreadGC2.dll

3. 将四个文件拷贝到windows\system32文件夹下面（小插曲:之前自己再配置时候按照网上的文章只拷贝两个文件 avcodec-51.dll, avformat-51.dll到这个文件，结果发现并不能配置成功。后来将后面avutil-49.dll, pthreadGC2.dll全部拷贝过去就成功了，很有可能这四个文件是有一定关联使用的。）

     avcodec-51.dll, avformat-51.dll, avutil-49.dll, pthreadGC2.dll

4. 然后需要到apache\bin文件下找到php.ini文件下允许使用dll文件加入extension=php_ffmpeg.dll 并允许     extension=php_gd2.dll， extension=php_gettext.dll这两个
改动后如下（去掉前面的分号就代表允许执行）

    extension=php_gd2.dll
    extension=php_gettext.dll
    extension=php_ffmpeg.dll

5. 重新启动wamp后使用phpinfo()函数看到一下信息配置：   //我两个环境一个apache一个IIS，iis不用重启就生效了，apache没试不知道， add by aboc

ffmpeg
ffmpeg-php version 0.5.2.1
libavcodec version Lavc51.43.0
libavformat version Lavf51.12.2
ffmpeg-php gd support enabled

 以上就表明ffmpeg在php环境中配置成功了。

6. 下面我们建立一个php的页面来测试是不是可以使用ffmpeg的一些函数功能。建立testvideo.php文件

 代码如下：

<?php

extension_loaded('ffmpeg');  //可不要

$ffmpegInstance = new ffmpeg_movie('C:\wamp\www\top10.mp4'); //这里要用绝对路径
echo "getDuration: " . $ffmpegInstance->getDuration()."<br>" .
"getFrameCount: " . $ffmpegInstance->getFrameCount()."<br>" .
"getFrameRate: " . $ffmpegInstance->getFrameRate()."<br>" .
"getFilename: " . $ffmpegInstance->getFilename()."<br>" .
"getComment: " . $ffmpegInstance->getComment()."<br>" .
"getTitle: " . $ffmpegInstance->getTitle()."<br>" .
"getAuthor: " . $ffmpegInstance->getAuthor()."<br>" .
"getCopyright: " . $ffmpegInstance->getCopyright()."<br>" .
"getArtist: " . $ffmpegInstance->getArtist()."<br>" .
"getGenre: " . $ffmpegInstance->getGenre()."<br>" .
"getTrackNumber: " . $ffmpegInstance->getTrackNumber()."<br>" .
"getYear: " . $ffmpegInstance->getYear()."<br>" .
"getFrameHeight: " . $ffmpegInstance->getFrameHeight()."<br>" .
"getFrameWidth: " . $ffmpegInstance->getFrameWidth()."<br>" .
"getPixelFormat: " . $ffmpegInstance->getPixelFormat()."<br>" .
"getBitRate: " . $ffmpegInstance->getBitRate()."<br>" .
"getVideoBitRate: " . $ffmpegInstance->getVideoBitRate()."<br>" .
"getAudioBitRate: " . $ffmpegInstance->getAudioBitRate()."<br>" .
"getAudioSampleRate: " . $ffmpegInstance->getAudioSampleRate()."<br>" .
"getVideoCodec: " . $ffmpegInstance->getVideoCodec()."<br>" .
"getAudioCodec: " . $ffmpegInstance->getAudioCodec()."<br>" .
"getAudioChannels: " . $ffmpegInstance->getAudioChannels()."<br>" .
"hasAudio: " . $ffmpegInstance->hasAudio();
?>

 7.执行后如果拿到视频的一些信息如下就表示环境配置成功了，那我们就可以开始开发我们的视频转换了。

执行结果：

getDuration: 811.13336181641
getFrameCount: 12167
getFrameRate: 15
getFilename: C:\wamp\www\top10.mp4
getComment:
getTitle:
getAuthor:
getCopyright:
getArtist:
getGenre:
getTrackNumber: 0
getYear: 0
getFrameHeight: 240
getFrameWidth: 320
getPixelFormat: yuv420p
getBitRate: 269769
getVideoBitRate:
getAudioBitRate:
getAudioSampleRate: 48000
getVideoCodec: mpeg4
getAudioCodec: mpeg4aac
getAudioChannels: 2
hasAudio: 1

视频截图的话如下方法： //add by aboc

$ff_frame = $ffmpegInstance->getFrame(rand(1,$ffmpegInstance->getFrameCount())); //随机截取某一帧
$gd_image = $ff_frame->toGDImage();
imagejpeg($gd_image,'t.jpg');
imagedestroy($gd_image);

echo '<img src="t.jpg" />';

Windows服务器下IIS设置伪静态 IIS Rewrite组件方法
2012-1-30 18:30 Monday  

1、将下载的IIS Rewrite 组件解压，放到适当的目录（如 C:Rewrite）下，IIS Rewrite 组件下载http://www.helicontech.com/download-isapi_rewrite.htm，IIS Rewrite 简化版组件下载http://soft.duoduo123.com/tool/，下载下来解压后不用安装拷到目录下设置好即可使用。

注：IIS Rewrite简单使用方法介绍：一个功能强大的URL处理引擎,功能和Apache的 mod_Rewrite类似,这个是For IIS版本 可以把像list.asp?id=234 这样的链接映射成 list/234.html 这样就有利于在GG中的排名

完全版(Full)与简化版(Lite)的最大的区别在于可以让每个站点自定义URL重写规则（Rewrite Rule），也就是只要将写好的httpd.ini放在站点根目录，就能使用了。

安装说明:下载后可以解压出 ISAPI_Rewrite.dll ，httpd.ini 这两个文件放到某个文件夹下面，然后在 IIS 站点属性的 ISAPI 中加载 ISAPI_Rewrite.dll  就可以了, httpd.ini  是配置文件里面有例子。如果加载不成功的话 请给 ISAPI_Rewrite.dll   安全属性为完全。

配置了asp.net的IIS出现“/”应用程序中的服务器错误的解决方法
2012-1-30 18:28 Monday  

php扩展已经添加好了，但是访问出现如下问题：

“/”应用程序中的服务器错误。无法找到资源。 说明: HTTP 404。您正在查找的资源(或者它的一个依赖项)可能已被移除，或其名称已更改，或暂时不可用。请检查以下 URL 并确保其拼写正确。

请求的 URL: /


把那个asp.net版本改成2.0就可以了
centos FTP服务器的架设和配置
2012-1-30 18:27 Monday  

yum install vsftpd

2.启动/重启/关闭vsftpd服务器
[root@localhost ftp]# /sbin/service vsftpd restart
Shutting down vsftpd: [ OK ]
Starting vsftpd for vsftpd: [ OK ]
OK表示重启成功了.
启动和关闭分别把restart改为start/stop即可.
如果是源码安装的,到安装文件夹下找到start.sh和shutdown.sh文件,执行它们就可以了.

3.与vsftpd服务器有关的文件和文件夹
vsftpd服务器的配置文件的是: /etc/vsftpd/vsftpd.conf

vsftpd服务器的根目录,即FTP服务器的主目录:
在/var/ftp处pub处
如果你想修改服务器目录的路径,那么你只要修改/var/ftp到别处就行了

4.添加FTP本地用户
有的FTP服务器需要用户名和密码才能登录,就是因为设置了FTP用户和权限.
FTP用户一般是不能登录系统的,只能进入FTP服务器自己的目录中,这是为了安全.这样的用户就叫做虚拟用户了.实际上并不是真正的虚拟用户,只是不能登录SHELL了而已,没能力登录系统.

/usr/sbin/adduser -d /opt/test_ftp -g ftp -s /sbin/nologin test
这个命令的意思是:
使用命令(adduser)添加test用户,不能登录系统(-s /sbin/nologin),自己的文件夹在(-d /opt/test_ftp)),属于组ftp(-g ftp)
然后你需要为它设置密码 passwd test
这样就添加了一个FTP用户了.下面的示例可以帮助你进入FTP服务器了.

[root@localhost ftp]# ftp
ftp> open 192.168.0.33
Connected to 192.168.0.33 (192.168.0.33).
220 (vsFTPd 2.0.5)
Name (192.168.0.33:gxl): test
331 Please specify the password.
Password:
230 Login successful.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> quit
221 Goodbye.

在windows中,只要在浏览器中输入 ftp://192.168.0.33 进入FTP服务器,然后 右键 登录,输入用户名和密码就可以登录自己的目录了.
当然你要保证自己能读写自己的目录,就要在配置文件vsftpd.conf里设置一下就可以读写了.
local_enable=yes
write_enable=yes
local_umask=022

5.匿名上传下载
修改配置文件即可vsftpd.conf,确定有以下几行,没有自己添加进去就可以了.
anonymous_enable=yes
anon_upload_enable=yes
anon_mkdir_write_enable=yes
anon_umask=022

然后你可以新建一个文件夹,修改它的权限为完全开放,任何用户就可以登录这个文件夹,并上传下载文件:
mkdir /var/ftp/guest
chmod 777 /var/ftp/guest

6.定制进入FTP服务器的欢迎信息
在vsftpd.conf文件中设置:
dirmessage_enable=yes
然后进入用户目录建立一个.message文件,输入欢迎信息即可(我这里写入的是Welcome to gxlinux's FTP!):
[root@localhost test_ftp]# ftp 192.168.0.33
Connected to 192.168.0.33 (192.168.0.33).
220 (vsFTPd 2.0.5)
Name (192.168.0.33:gxl): test
331 Please specify the password.
Password:
230-Welcome to gxlinux's FTP!
230 Login successful.
Remote system type is UNIX.
Using binary mode to transfer files.

7.实现虚拟路径
将某个目录挂载到FTP服务器下供用户使用,这就叫做虚拟路径.
比如将gxl用户的目录挂载到FTP服务器中,供FTP服务器的用户使用,使用如下命令即可:
[root@localhost opt]# mount --bind /home/gxl /var/ftp/pub #使用挂载命令
[root@localhost opt]# ls /var/ftp/pub
LumaQQ Screenshot.png 桌面

开机自动挂载可用

这样子的方式

 

8.打开vsFTPd的日志功能
添加下面一行到vsftpd.conf文件中,一般情况下该文件中有这一行,只要把前面的注释符号#去掉即可,没有的话就添加,或者修改:
xferlog_file=/var/log/vsftpd.log

9.限制链接数,以及每个IP最大的链接数
修改配置文件中,例如vsftp最大支持链接数100个,每个IP能支持5个链接:
max_client=100
max_per=5

10.限制传输速度
修改配置文件中,例如让匿名用户和vsftd上的用户(即虚拟用户)都以80KB=1024*80=81920的速度下载
anon_max_rate=81920
local_max_rate=81920

11.将用户(一般指虚拟用户)限制在自家目录
修改配置文件中,这样用户就只能访问自己家的目录了:
chroot_local_user=yes
如果只想某些用户仅能访问自己的目录,其它用户不做这个限制,那么就需要在chroot_list文件(此文件一般是在/etc/vsftpd/中)中添加此用户.
编辑此文件,比如将test用户添加到此文件中,那么将其写入即可.一般的话,一个用户占一行.
[root@localhost vsftpd]# cat chroot_list
test

12.绑定某个IP到vsFTPd
有时候要限制某些IP访问服务器,只允许某些IP访问,例如只允许192.168.0.33访问这个FTP,同样修改配置文件:
listen_address=192.168.0.33


配置vsftpd.conf
                   anonymous_enable=NO            #禁止匿名

虚拟用户其他设置

      在/etc/vsftpd/vsftpd.chroot_list 文件中写入允许登陆的虚拟用户名称，每行一个
      在/etc/vsftpd/vsftpd_user_conf 文件夹中创建一个以虚拟用户用户名命名的文件，
      写入：local_root = /var/FTP/子目录名
      然后在/var/FTP下创建一个对应的目录即可

 

当虚拟用户权限出现不能创建目录，上传时，是因为selinux搞的鬼，可以采用以下方法解决

1
yum remove selinux* -y

当然你也可以

 

2
vi /etc/selinux/config

修改为：SELINUX=disabled

3.setsebool -P ftpd_disable_trans 1

把他禁止掉，看你自己喜欢了。

重试，问题解决！

 

编辑/etc/vsftpd/vsftpd.conf，注意在等号前的部分大小写是敏感的，一定要全部小写，最后所有产生效用

的设置调如下。
anonymous_enable=NO   不允许匿名登录（默认为YES，需要修改）
local_enable=YES   允许本地用户登录（默认）
write_enable=YES   开放本地用户登录后的修改权限（默认）
local_umask=022   上传文件默认权限为755（777-022）（默认）
dirmessage_enable=YES   欢迎信息（默认）
xferlog_enable=YES   记录log（默认）
connect_from_port_20=YES   （默认）
xferlog_std_format=YES   log格式（默认）
listen=YES   （默认）
chroot_local_user=YES   限制用户登陆后只能在自身目录（新添加）
pam_service_name=vsftpd   （默认）
tcp_wrappers=YES   （默认）
最后删除一条默认的userlist_enable=YES
保存退出后

接下来建立一个不能在本地登录而只能使用ftp的用户，假设用户名为ftpuser，个人所属的文件夹

为/var/ftp/ftpuser

重要一，

命令如下
useradd -g ftp -d /var/ftp/ftpuser -s /sbin/nologin ftpuser
建立完成后使用passwd ftpuser命令设置密码

重要二，

cd /etc/vsftpd/

touch chroot_list

vi chroot_list 添加 ftpuser

重启vsftpd

附带：如果上传时出现以下报错（man man ftpd_selinux得到帮助）：

vsftp " 553 Could not create file"

解决方法：

1. 执行

setsebool -P ftpd_disable_trans 1
2.

service vsftpd restart

 

 

虚拟用户登录530错误。。

解决方法：

cp Path/RedHat/vsftpd.pam /etc/pam.d/ftp

path为vsftp解压缩源文件目录

这是因为我们RHEL启用了PAM,所在用到vsftp时需要用到 /etc/pam.d/ftp这个文件（默认源码安装的不会有这个文件），因此除了匿名用户外本地用户无法登录。

结果我这么一做，匿名用户也登不上了

 

 

vsftp 上传 失败 错误 200 227 553


An error occurred copying a file to the FTP server.Make sure you have permission to put file on the server.

Details:

今天遇到这个错误

解决方法

关闭selinux

修改/etc/vsftpd.conf

write_enable=YES

假设要上传这个目录是/home/ftp 

他的权限应该是770，owner是用户名，group是user

chmod 770 /home/ftp    实事证明 弄成770是不行的，要弄成755 ，要不然web不能访问

chown 用户名:用户组 /home/ftp

 

OK~搞定

关于session和memcache的若干问题[转]
2012-1-30 18:26 Monday  

来源:http://phpec.com/?action=show&id=33

一直以来,由于php本身的session机制不能跨机,令很多phper感到不爽,现在流行的解决方案主要有:
1)使用数据库来实现
2)自己写server端,通过改写session处理函数来请求
3)使用nfs等跨机存储来保存session
4)使用memcache来保存
5)使用zend platform提供的解决方案

其中的1-4都是通过改用可以跨机的储存机制,再使用session_set_save_handler()来实现,5是zend公司的商业产品(不过据之前在使用的同事反映,效果不太满意),以上的方案,各有利弊,不在本文讨论范围

无论是用memcache,还是db,nfs,其原理是一样的,都是通过session_set_save_handler函数来改变默认的处理方式,通 过指定回调函数来自定义处理,可以参考手册的session_set_save_handler()函数部分,有例子,比较容易明白

以下是一些我在使用memcache来实现时的一些记录:
1)使用类来实现时,各回调函数都定义为静态方法,在类的构造中使用session_set_save_handler注册回调函数, 如:
session_set_save_handler(
                array('memSession', 'open'),
                array('memSession', 'close'),
                array('memSession', 'read'),
                array('memSession', 'write'),
                array('memSession', 'destroy'),
                array('memSession', 'gc')
          );
memSession为类名,要使用session,则先new memSession,再session_start();


2)生存期和垃圾回收
memCache的set命令有生存期,即使用set命令添加值时,可加上lifetime,此时间可以作为session的生存期,用户在此时间内没有 动作,则会失效,但有动作则不会失效(因为每一个脚本结束时,都会执行write和close,此时lifetime就会被更新了),当然,如果使用 cookie传递SID,则控制SESSION生存期可以用:ini_set('session.cookie_lifetime',time)来设定, 这其实是控制cookie的有效时间,如果session赖以生存的cookie消失了,当然session也就活不了,使用 cookie_lifetime来控制的话,无论有无动作,都将在指定的时间后过时

gc是指垃圾回收,在session中是指清理过期的session数据,影响的参数有:
session.gc_maxlifetime 被视为垃圾前的生存期,超过此时间没有动作,数据会被清走
注意的是,gc不是每次启动会话都会被执行,而是由session.gc_probability 和 session.gc_divisor的比率决定的

结论:控制SESSION的生存期有几种方法
一是cookie_lifttime,这种方式无论有无动作,都会在指定时间内销毁
二是在read中根椐保存时间控制,此方法在有动作时时间会一直有效
三设定session.gc_probability 和 session.gc_divisor的比率为1(即每次会话都会启用gc),再设定gc.maxlifetime来指定生存期,此方法也是在用户有动作时时间一直有效

3)回调函数的执行时机
open 在运行session_start()时执行
read 在运行session_start()时执行,因为在session_start时,会去read当前session数据并写入$_SESSION变量
destroy 在运行session_destroy()时执行
close 在脚本执行完成或调用session_write_close() 或 session_destroy()时被执行,即在所有session操作完成后被执行
gc 执行概率由session.gc_probability 和 session.gc_divisor的值决定,时机是在open,read之后,即session_start会相继执行open,read和gc
write 此方法在脚本结束和使用session_write_close()强制提交SESSION数据时执行

结论:
session_start //执行open(启动会话),read(读取session数据至$_SESSION),gc(清理垃圾)
脚本中间所有对$_SESSION的操作均不会调用这些回调函数
session_destroy //执行destroy,销毁当前session(一般是删除相应的记录或文件),相应地,此回调函数销毁的只是session的数据,但此时

var_dump一下$_SESSION变量,仍然有值的,但此值不会在close后被write回去
session_write_close() //执行write和close,保存$_SESSION至存储,如不手工使用此方法,则会在脚本结束时被自动执行

清晰了以上信息,将对你清楚了解SESSION的工作原理有很大的帮助...

4)直接使用memcache作session处理
在我写了一系列的memcache来保存session的代码后,无意中发现,可以直接在php.ini中设定使用memcache作为session处理,而无须另外编码,方法是:
修改php.ini中的以下值
session.save_handler = memcache
session.save_path = 'tcp://host1:11211' #有多个时直接用","分隔即可
如果只想在特定的应用里使用memcache储存session,可以使用ini_set的方法对以上两个参数进行设定

要测试一下是否真正用上了memcache,可以先捕足到使用的PHPSESSID,再作为KEY用memcach去读一下,就清楚了

Session改为memcached中存储，能解决跨域共享session的问题。

安装php的soap扩展
2012-1-30 18:25 Monday  

1.windows下

去掉extension=php_soap.dll前的;号重启iis或是apache即。

2.centos下

  通过yum安装  yum install php-soap 然后重启apache。

中途如果有报thread.error: can't start new thread 这个错误，则用如下方法解决

编辑 /etc/yum/pluginconf.d/fastestmirror.conf

将enabled=1修改为enabled=0，禁用该功能就可以了。

 通过重编译来扩展，则进行如下操作，来源http://www.9enjoy.com/php5-soap-make/

切换到php5安装目录的soap目录
cd /soft/php-5.2.8/ext/soap
视php安装目录定
/usr/local/php5/bin/phpize
编译soap.so
./configure --with-php-config=/usr/local/php5/bin/php-config --enable-soap
make
make install

Installing shared extensions:     /usr/local/php5/lib/php/extensions/no-debug-zts-20060613/
提示编译后的soap.so文件保存在了/usr/local/php5/lib/php/extensions/no-debug-zts-20060613/目录下。

修改php.ini
vi /usr/local/apache2.2.0/conf/php.ini

如 果之前没有安装过extension，则需要将extension_dir = "./"改为extension_dir = "/usr/local/php5/lib/php/extensions/no-debug-zts-20060613/"，如果已经装过，这步之前就 已经改过了。
再其后面加一句：
extension = "soap.so"

重新启动apache，在phpinfo中就有soap的信息了。
Soap Client  enabled  
Soap Server  enabled  

在另一台在phpsize时提示了一些错误，不过不影响之后的编译安装。

smarty3.0和__autoload()冲突
2012-1-30 18:24 Monday  

今天更新了一下smarty到3.0，结果发现项目中的__autoload()不能用了，原来是因为smarty改变了autoload的方式。

解决方法如下：

function autoload($className){
    if (file_exists(SITEROOT.'include/module/'.$className.'.class.php'))
    include SITEROOT.'include/module/'.$className.'.class.php';
    else
    die('类'.$className.'文件不存在');
}
spl_autoload_register("autoload");

用上面的方式还可以依顺序同时载入几个autoload方法哦

PHP无法操作memcached提示Permission denied
2012-1-30 18:23 Monday  

AMP环境是用yum安装，CentOS系统，telnet memcached正常。PHP的memcache模块及socket都正常

分析后发现系统SeLinux开启,httpd只能访问443,80端口。

找到原因后就好办了，关闭SElinux就可以了。

修改/etc/selinux/config

SELINUX=disabled

重启系统或执行：

setenforce 0

搞定，泡茶或继续干活。

==========

以下介绍一下SELinux相关的工具

/usr/bin/setenforce 修改SELinux的实时运行模式
setenforce 1 设置SELinux 成为enforcing模式
setenforce 0 设置SELinux 成为permissive模式
如果要彻底禁用SELinux 需要在/etc/sysconfig/selinux中设置参数selinux=0 ，或者在/etc/grub.conf中添加这个参数
/usr/bin/setstatus -v
察看系统的状态
以下是运行输出，请参考
SELinux status: enabled
SELinuxfs mount: /selinux
Current mode: enforcing
Policy version: 18

mysql修复坏表命令mysqlcheck
2012-1-30 18:23 Monday  
mysqlcheck -A -r -c -p
输入密码来修复就可以了
    -A    检查所有数据库中的所有表
    -c    检查表的错误
    -r    可以修复大部分问题的修复（如果不赶时间的话，可考虑-e参数代替）
    -o    优化表（如果表太大，写操作比较频繁的话，可能会花较长时间）
    -p    指定加密码
如何让APACHE禁止列目录
2012-1-30 18:22 Monday  

方法一，首先修改 httpd.conf 配置文件：
vi /etc/httpd/conf/httpd.conf
查找 Options Indexes FollowSymLinks，修改为 Options -Indexes。
 


 
方法二，在www 目录下的修改 .htaccess 配置文件：
加入 Options -Indexes
