Setup SVN server on ubuntu 14.04

Start the installation .
Step 1 : Update the repositories.
sudo apt-get update

Step 2 : Install SVN and apache webserver (To access SVN through http ) .
sudo apt-get install subversion apache2 libapache2-svn apache2-utils

Step 3 » Create a directory and create a new repository in that directory ( testrepo is the repository name ).
sudo mkdir -p /svn/repos/
sudo svnadmin create /svn/repos/testrepo

Step 4 » Change ownership for the repository.
sudo chown -R www-data:www-data /svn/repos/testrepo

Step 5 » Create a file testrepo.conf in /etc/apache2/sites-available/ and add the below lines for creating apache virtual host.
<Location /svn>
  DAV svn
  SVNParentPath /svn/repos/
  AuthType Basic
  AuthName "Test Repo"
  AuthUserFile /etc/svnpasswd
  Require valid-user
</Location>
SVNParentPath /svn/repos/ : Parent Directory without repository name.
AuthUserFile /etc/svnpasswd : File need to be created ( Step 8) for user details.

Step 6 »Enable the Site ( testrepo in the below command should match the file name created in the previous step )
sudo a2ensite testrepo

Step 7 » Restart or reload apache service.
sudo service apache2 reload

Step 8 » Create user for accessing repository and add the user details to /etc/svnpasswd file.
Use this command to create first user.
sudo htpasswd -cm /etc/svnpasswd user1

Use the same command without c option to create additional users.
sudo htpasswd -m /etc/svnpasswd user2

Step 9 » Access http://yourip/svn/testrepo in your browser ( Eg http://10.0.1.15/svn/testrepo ) and you can see the page like below after successful authentication.

Setting up a cron in AWS Linux/Ubuntu

1. Login to server using SSH (Windows users PuTTY)
2. sudo crontab -l
3. sudo crontab -e
4. Linux : Open vim editor and allow to enter commands
5. Ubuntu : For the first time it asks which editor to use (nano is easy)
6. Enter following commands and save the file

MAILTO=yyy@gmail.com

*/5 * * * * /usr/bin/wget http://yyy.com/mail201506/index.php >/dev/null

>/dev/null

Send all the normal output to a place called "/dev/null" which is basically like a black hole. It accepts anything you dump there, but you will never see it again.

Install Git on Ubuntu

sudo apt-get update
sudo apt-get install build-essential libssl-dev libcurl4-gnutls-dev libexpat1-dev gettext unzip
wget https://github.com/git/git/archive/v1.9.2.zip -O git.zip (You can get latest version from git)
unzip git.zip
cd git-*
make prefix=/usr/local all
sudo make prefix=/usr/local install

if you want to upgrade to a later version, you can simply clone the repository and then build and install:
git clone https://github.com/git/git.git

Following commands will rebuild and reinstall the package
make prefix=/usr/local all
sudo make prefix=/usr/local install

git config --global user.name "Your Name"
git config --global user.email "youremail@domain.com"

Install Node.js on Ubuntu AND Linux

Ubuntu

sudo apt-get update

Then use apt-get to install Node.js build dependencies:
sudo apt-get install -y build-essential openssl libssl-dev pkg-config

Move to /usr/src directory - the usual place to hold software sources.
cd /usr/src

pick the latest compressed source archive from Node.js website at http://nodejs.org/download/.
sudo wget http://nodejs.org/dist/v0.12.4/node-v0.12.4.tar.gz

Uncompress the source files and move into that directory.
sudo tar zxf node-v0.12.4.tar.gz
cd node-v0.12.4

Prepare compiler commands, by executing the configure script:
sudo ./configure

It will read the properties of the system to prepare compiler flags. Ie. it could be a system architecture (32/64bit, CPU specific flags etc). With it, Now ready to actually compile the source now. To do that, just type:
sudo make

To make this available system-wide:
sudo make install

Linux

Update software repository to the latest versions:
sudo yum -y update

Install "Development Tools". It's a group of tools for compiling software from sources.
sudo yum -y groupinstall "Development Tools"

Move to /usr/src directory - the usual place to hold software sources.
cd /usr/src

Install and start the LAMP web server on Amazon Linux And Ubuntu

Linux

Install updates
[ec2-user ~]$ sudo yum update -y

you can install the Apache web server, MySQL, and PHP software packages. Use the yum install command to install multiple software packages and all related dependencies at the same time.
[ec2-user ~]$ sudo yum install -y httpd24 php56 mysql55-server php56-mysqlnd

Start Apache
[ec2-user ~]$ sudo service httpd start

Start apache at each system boot
[ec2-user ~]$ sudo chkconfig httpd on

Check httpd is on
[ec2-user ~]$ chkconfig --list httpd

Modify ownership and permissions for document root

Add a www group to your instance, and you give that group ownership of the /var/www directory and add write permissions for the group. Any members of that group will then be able to add, delete, and modify files for the web server.

[ec2-user ~]$ sudo groupadd www

[ec2-user ~]$ sudo usermod -a -G www ec2-user (Add user to www group)

[ec2-user ~]$ exit (logout)

[ec2-user ~]$ groups (Verify membership in www group)

[ec2-user ~]$ sudo chown -R root:www /var/www (Change the group ownership of /var/www and its contents to the www group.)

Change the directory permissions of /var/www and its subdirectories to add group write permissions and to set the group ID on future subdirectories.
[ec2-user ~]$ sudo chmod 2775 /var/www
[ec2-user ~]$ find /var/www -type d -exec sudo chmod 2775 {} +

Recursively change the file permissions of /var/www and its subdirectories to add group write permissions.
[ec2-user ~]$ find /var/www -type f -exec sudo chmod 0664 {} +

[ec2-user ~]$ sudo service mysqld start (Start mysql server)

[ec2-user ~]$ sudo mysql_secure_installation (Run mysql_secure_installation, here u can set password for mysql etc...)

[ec2-user ~]$ sudo chkconfig mysqld on (Start mysql at every boot)
