How To Install Subversion on Ubuntu 16.04

Subversion is an open source version control system. It helps you keep track of a collection of files and folders. Any time you change, add or delete a file or folder that you manage with Subversion, you commit these changes to your Subversion repository, which creates a new revision in your repository reflecting these changes. You can always go back, look at and get the contents of previous revisions. SVN supports several protocols for network access: SVN, SVN+SSH, HTTP, HTTPS. If you are behind a firewall, HTTP-based Subversion is advantageous since SVN traffic will go through the firewall without any additional firewall rule setting.

Install Subversion on Ubuntu 16.04

This article assumes you have at least basic knowledge of linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation Subversion on a Ubuntu 16.04 (Xenial Xerus) server.

Step 1. First make sure that all your system packages are up-to-date by running these following apt-get commands in the terminal.

sudo apt-get update
sudo apt-get upgrade

Step 2. Installing Apache web server.

First you need to install Apache web server to access svn server using http urls:

apt-get install apache2

Step 3. Installing Subversion.

Use following command to install subversion packages and there dependencies. Also install svn module for Apache libapache2-mod-svn packages on your system:

apt-get install subversion libapache2-mod-svn libapache2-svn libsvn-dev
a2enmod dav
a2enmod dav_svn

Step 4. Configure Apache for Subversion.

Subversion Apache module package creates an configuration file /etc/apache2/mods-enabled/dav_svn.conf. You just need to make necessary changes to it:

### nano /etc/apache2/mods-enabled/dav_svn.conf

Alias /svn /var/lib/svn

DAV svn
SVNParentPath /var/lib/svn

AuthType Basic
AuthName "Subversion Repository"
AuthUserFile /etc/apache2/dav_svn.passwd

After making above changes, restart Apache service:

systemctl restart apache2

Step 5. Create First SVN Repository.

Create your first svn repository named firstrepo, You can use any suitable name:

mkdir -p /var/lib/svn/
svnadmin create /var/lib/svn/myrepo
chown -R www-data:www-data /var/lib/svn
chmod -R 775 /var/lib/sv

Step 6. Create account and password for SVN.

Following commands will add two users for svn. It will prompt for users password to be assigned.

htpasswd -m /etc/apache2/dav_svn.passwd wpcademy.com
htpasswd -m /etc/apache2/dav_svn.passwd chedelics

Let’s restart Apache service again:

systemctl restart apache2

Step 7. Accessing Repository in Browser.

Subversion will be available on HTTP port 80 by default. Open your favorite browser and navigate to http://yourdomain.com/svn/myrepo/ or http://server-ip/svn/myrepo/ and will prompt for authentication. Use login credentials created in Step 6. If you are using a firewall, please open port 80 to enable access to the control panel.

How To Install HHVM on Ubuntu 16.04 LTS

HipHop Virtual Machine (HHVM) is a virtual machine developed and open sourced by Facebook to process and execute programs and scripts written in PHP. Facebook developed HHVM because the regular Zend+Apache combination isn’t as efficient to serve large applications built in PHP.

This article assumes you have at least basic knowledge of linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation HHVM (HipHop Virtual Machine) on a Ubuntu 16.04 (Xenial Xerus) server.
Install HHVM on Ubuntu 16.04 LTS

Step 1. First make sure that all your system packages are up-to-date by running these following apt-get commands in the terminal.

sudo apt-get update
sudo apt-get upgrade

Step 2. Installing HHVM.

First we need to add the HHVM repository to your Ubuntu Server with the following command:

apt-get install software-properties-common
apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0x5a16e7281be7a449
add-apt-repository "deb http://dl.hhvm.com/ubuntu $(lsb_release -sc) main"

Now we can install HHVM with the following command:

apt-get update
apt-get install -y hhvm

HHVM should have been successfully installed, to make sure run the following command:

$ php -v

HipHop VM 3.15.0 (rel)

HHVM includes an excellent script to install FastCGI based on web server you have installed. This section will help you configure HHVM in the FastCGI mode with the Apache and Nginx servers:

With Apache

Configuring HHVM to work in the FastCGI mode with Apache is extremely simple. All you need to do is execute the following following script:

sudo /usr/share/hhvm/install_fastcgi.sh

With Nginx

If you are using Nginx with PHP-FPM, you’ll have to modify the configuration file to disable the use of PHP-FPM. This file is normally located at /etc/nginx/sites-available/default.Look for the following section and make sure it’s all commented (by adding a # at the beginning of each line):

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
# location ~ \.php$ {
# fastcgi_split_path_info ^(.+\.php)(/.+)$;
# # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
#
# # With php5-cgi alone:
# fastcgi_pass 127.0.0.1:9000;
# # With php5-fpm:
# fastcgi_pass unix:/var/run/php5-fpm.sock;
# fastcgi_index index.php;
# include fastcgi_params;
#}

After doing this, execute the following script:

sudo /usr/share/hhvm/install_fastcgi.sh

Finally, run the commands below to start up HHVM:

systemctl start hhvm

Step 3. Testing HHVM.

Install Magento on Ubuntu 16.04 LTS

Step 1. First make sure that all your system packages are up-to-date by running these following apt-get commands in the terminal.

sudo apt-get update
sudo apt-get upgrade

Step 2. Install LAMP (Linux, Apache, MariaDB, PHP) server.

A Ubuntu 16.04 LAMP server is required. If you do not have LAMP installed, you can follow our guide here. Also install all required PHP modules:

apt-get install imagemagick php7.0-curl php7.0-gd php7.0-mbstring php7.0-mysql libapache2-mod-php7.0 php7.0-mcrypt

Step 3. Installing Magento.

First thing to do is to go to Magento’s download page and download the latest stable version of Magento, At the moment of writing this article it is version 2.1.2:

wget http://www.magentocommerce.com/downloads/assets/2.1.2/magento-2.1.2.zip

Unpack the Magento archive to the document root directory on your server:

unzip magento*.zip
cp -rf magento/* /var/www/html/

We will need to change some folders permissions:

chown -R www-data:www-data /var/www/html/
chmod -R 755 /var/www/html

Step 4. Configuring MariaDB for Magento.

mysql_secure_installation

Configure it like this:

- Set root password? [Y/n] y
- Remove anonymous users? [Y/n] y
- Disallow root login remotely? [Y/n] y
- Remove test database and access to it? [Y/n] y
- Reload privilege tables now? [Y/n] y

Next we will need to log in to the MariaDB console and create a database for the Magento. Run the following command:

mysql -u root -p

This will prompt you for a password, so enter your MariaDB root password and hit Enter. Once you are logged in to your database server you need to create a database for Magento installation:

CREATE DATABASE magentodb;
GRANT ALL PRIVILEGES ON magentodb . * TO magento@'localhost' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;
flush privileges;
exit

Step 5. Configuring Apache web server for Magento.

Create a new virtual host directive in Apache. For example, create a new Apache configuration file named ‘magento.conf’ on your virtual server:

touch /etc/apache2/sites-available/magento.conf
ln -s /etc/apache2/sites-available/magento.conf /etc/apache2/sites-enabled/magento.conf
nano /etc/apache2/sites-available/magento.conf

Add the following lines:

ServerAdmin [email protected]
DocumentRoot /var/www/html/
ServerName your-domain.com
ServerAlias www.your-domain.com

Options FollowSymLinks
AllowOverride All

ErrorLog /var/log/apache2/your-domain.com-error_log
CustomLog /var/log/apache2/your-domain.com-access_log common

Save and close the file. Restart the apache service for the changes to take effects:

systemctl restart apache2

Step 6. Configure PHP for Magento.

Now here we should allow Magento to use enough PHP memory (it is recommended that PHP should be allowed 512 MB of RAM). To do that, run the commands below to open the configuration file:

nano /etc/php5/apache2/php.ini

Search for the line ‘memory_limit‘ in the file:

memory_limit = 128M
### And change the value to 512 ###
memory_limit = 512M

Restart Apache for the changes to take effect using the following command:

systemctl restart apache2

Step 7. Accessing Magento.

Magento will be available on HTTP port 80 by default. Open your favorite browser and navigate to http://yourdomain.com/ or http://server-ip and complete the required the steps to finish the installation. If you are using a firewall, please open port 80 to enable access to the control panel.
