DESCRIPTION & PROCEDURE:

CollabNet Subversion Edge - Linux 32/64-bit

Version 2.0.0

Release Date: June 14, 2011

Contents

1. Overview

2. Platform and configuration

3. Requirements

4. Installation notes

5. Updates

6. Documentation

7. Known issues

8. Support for CollabNet Subversion Edge

9. About Subversion and CollabNet

1. Platform and configuration

Product: CollabNet Subversion Edge

License: GNU Affero General Public License 3.0 (AGPLv3)

Certified platforms: Red Hat Enterprise Linux 5.x

CentOS 5.x

SuSE Linux Enterprise 11.x

2. Requirements

* Java 1.6 JRE/JDK must be installed. We recommend the JRE provided by

Sun/Oracle. When testing on 64-bit Linux we have used the 64-bit JVM.

* Python 2.4 to 2.6 must be installed.

3. Installation Notes

1. Set the JAVA_HOME environment variable, and point it to your Java 6 JRE

home. For example:

export JAVA_HOME=/usr/java/default

Test the variable:

$ $JAVA_HOME/bin/java -version

java version "1.6.0_20"

Java(TM) SE Runtime Environment (build 1.6.0_20-b02)

Java HotSpot(TM) Client VM (build 16.3-b01, mixed mode, sharing)

2. Switch to the folder where you want to install CollabNet Subversion

Edge. You must have write permissions to this folder.

$ cd /opt

3. Untar the file you downloaded from CollabNet.

$ tar zxf CollabNetSubversionEdge-x.y.z_linux-x86.tar.gz

This will create a folder named "csvn" in the current directory. You can

rename this folder if desired.

4. Install the application so that it will start automatically

when the server restarts. This command generally requires root/sudo to execute.

$ cd csvn

$ sudo -E bin/csvn install

5. Configure proxy settings. CollabNet Subversion Edge need access to the

internet to check for and install updates. If you need to go through a proxy to

access the internet, then you can configure the proxy by editing the

data/conf/csvn.conf file which was created by the previous step. Uncomment

and edit the HTTP_PROXY variable to configure your proxy server.

6. Start the server. Be sure that you are logged in as your own userid and not

running as root.

$ bin/csvn start

This will take a few minutes and the script will loop until it sees that the server

is running. If the server does not start, then try starting the server with this

command:

$ bin/csvn console

This will start the server but output the initial startup messages to the console.

The default administrator login is:

Address: http://localhost:3343/csvn

Username: admin

Password: admin

Subversion Edge also starts an SSL-protected version using a self-signed SSL

certificate. You can access the SSL version on this URL:

Address: https://localhost:4434/csvn

OUTPUT

https://localhost:4434/csvn

RESULT:

Thus the version control software was implemented and verified.

<td width="78">Username</td>

<td width="6">:</td>

<td width="294"><input name="myusername" type="text"

id="myusername"></td>

</tr>

<tr>

<td>Password</td>

<td>:</td>

<td><input name="mypassword" type="text" id="mypassword"></td>

</tr>

<tr>

<td> </td>

<td> </td>

<td><input type="submit" name="Submit" value="Login"></td>

</tr>

</table>

</td>

</form>

</tr>

</table>

Create Validation Page (checklogin.php):

<?php

$host="localhost"; // Host name

$username="root"; // Mysql default username

//$password=""; // Mysql No password

$db_name="student"; // Database name

$tbl_name="members"; // Table name

// Connect to server and select databse.

mysql_connect("$host", "$username")or die("cannot connect");

mysql_select_db("$db_name")or die("cannot select DB");

// username and password sent from form

$myusername=$_POST['myusername'];

$mypassword=$_POST['mypassword'];

$sql="SELECT * FROM $tbl_name WHERE

username='$myusername' and password='$mypassword'";

$result=mysql_query($sql);

// Mysql_num_row is counting table row

$count=mysql_num_rows($result);

// If result matched $myusername and $mypassword, table row must be 1 row

if($count==1)

echo "Welcome To Our Web Page";

else

echo "Wrong Username or Password";

?>

Output:

TYPE THE FOLLOWING IN THE BROWSER

http://localhost/HomePage.html

RESULT

http://localhost/HomePage.html

Aim:

To Write a Python program to create a table in MYSQL using database

connectivity

Steps to execute python programs:

1. Open the Gedit editor and write the program

2. Save the program with .py as extension

3. Execute the program using python filename.py

Program

#!/usr/bin/python

import MySQLdb

# Open database connection

db = MySQLdb.connect("localhost","root","","student" )

# prepare a cursor object using cursor() method

cursor = db.cursor()

# Drop table if it already exist using execute() method.

cursor.execute("DROP TABLE IF EXISTS college ")

# Create table as per requirement

sql = """CREATE TABLE college ( FIRST_NAME CHAR(20) NOT

NULL,LAST_NAME

CHAR(20), AGE INT, SEX CHAR(1))"""

cursor.execute(sql)

# disconnect from server

db.close()
