WLNSC1000 改機資訊

改了以後可以跑自己的Apache server...也就是可以跑php囉..

See Log:
cat /var/log/messages


==========Setup Apache=========
in directory /mnt/C
tar zxvf apachexxxxx
vi /mnt/C/sys/etc/env-ng
RCNG=1

APACHE2=1 (if apache path is /mnt/C/sys/apache2)

APACHE22=1 (if apache path is /mnt/C/sys/apache22)


cp /mnt/C/sys/etc/php-ini-dist /mnt/C/sys/etc/php-ini
=========apache/conf/httpd.conf============

Convert QString to Char*

If you went to convert prototype QString to char*,you can using this method:

int main(int argc, char **argv)
{
    QApplication app(argc, argv);
    QString str1 = "Test";

    //method 1
    strcpy(c_str2,str1.toUtf8());
 
    //method 2 
    QByteArray ba = str1.toLatin1();
    const char *c_str2 = ba.data();

    printf("str2: %s", c_str2);
    return app.exec();    
}

Read and Write large file(over 2G) in C

If you want to open a large file in Linux


You can try it

Add those flag into your Makefile

-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64

Modify you fseek and ftell to fseeko and ftello

Finish

IP的轉換

1、htonl ()和ntohl( )

u_long PASCAL FAR ntohl (u_long netlong);

u_short PASCAL FAR ntohs (u_short netshort);

ntohl( )-----網路順序轉換成主機順序

u_long PASCAL FAR htonl (u_long hostlong);

u_short PASCAL FAR htons (u_short hostshort);

htonl ()-----主機順序轉換成網路順序

2、inet_addr( )和inet_ntoa ( )

unsigned long PASCAL FAR inet_addr (const char FAR * cp);

char FAR * PASCAL FAR inet_ntoa (struct in_addr in);

inet_addr函數需要一個字串作為其參數，該字串指定了以點分十進位格式表示的IP位址（例如：192.168.0.16）。而且inet_addr函數會返回一個適合分配給S_addr的u_long類型的數值。

Inet_ntoa函數會完成相反的轉換，它接受一個in_addr結構體類型的參數並返回一個以點分十進位格式表示的IP位址字串。

Linux下查詢UTC時間,UTC秒、日期轉換

查詢當下UTC秒

[Shell]date +%s
1270542114


UTC秒轉日期

[Shell]date -d "1970-01-01 UTC 1270538720 seconds"
Tue Apr 6 15:25:20 CST 2010

1270538720 是要轉換的秒


日期轉UTC秒

[Shell]date -d "20100101 00:00:01" +%s
1262275201

紅色部分是要轉換的時間

JAR Library: Export and Import

1. Export Library
   • Prepare source code
     • Create an Android project
     • Create source code, and fix all bug
     • Remove res/*
     • Remove unused source files
     • Edit AndroidManifest.xml to remove the statements that referes to resource, such as android:icon="@drwable/icon", android:label="@string/app_name"
   • Export library
     • On Package Explorer Panel of Eclipse, right-click the project, and select Export
     • Select Jave -> JAR file, then press "Next". At this time a dialog pops up.
     • On the right panel of "Select the resources to export:" group, unselect all items (such as .classpath, .project, AndroidManifest.xlm, default.properties), then press "Next"
     • Press "Next"
     • Press "Finish"
       
       Then the library is created.
       (Reference: Eclipse export jar files http://hi.baidu.com/etrigger/blog/item/e1fed134468b2fb2d0a2d3ad.html)
2. Import Library
   You can use a third party JAR in your application by adding it to your Eclipse project as follows:
   • In the Package Explorer panel, right-click on your project and select Properties.
   • Select Java Build Path, then the tab Libraries.
   • Press the Add External JARs... button and select the JAR file
   
   Alternatively, if you want to include third party JARs with your package, create a new directory for them within your project and select Add Library... instead.
   It is not necessary to put external JARs in the assets folder.

Apache2 開啟 .htaccess 功能 & CodeIgniter 移除 index.php

1.一般都是使用.htaccess但是可以設定要依照別的檔案名稱

/etc/apache2/apache2.conf

內的

AccessFileName .htaccess


2.在httpd.conf可以設定要作用的路徑


Options FollowSymLinks
AllowOverride All


/var/www/admin
就是要作用的資料夾

3.載入mod_rewrite以啟用RewriteEngine模組
sudo a2enmod rewrite

4.設定完重開apache2
sudo /etc/init.d/apache2 restart

5.在資料夾放入.htaccess檔案
設定轉換路徑
EX:
RewriteEngine On
RewriteBase /admin
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php/$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

上面的/admin對應之前的/var/www/admin

不過他是網路上的第一層資料夾
ex:http://localhost/admin

將.htaccess放到/var/www/admin/

下就好了

以下給CodeIgniter使用
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
如果要把網址後面的index.php取消
上面的步驟照作之外

下面在設定一些東西
config.php

$config['index_page'] = "";
$config['uri_protocol'] = "REQUEST_URI";

大概就這樣吧....
