Dolphin

Dolphin is an open-source software package for building social networks, dating sites and niche communities. Dolphin’s features include video chat, video messenger, iPhone app, Android App, Adobe AIR desktop app, groups, events, blogs, files, media sharing, a store, and more. Dolphin also allows developers to create plugins to add additional functionality or features. You can use the Dolphin Market to find extensions, design templates, mods, plugins, language packs and third party software integrations.

Dolphin Prerequisites

Dolphin requires a standard LAMP (Linux, Apache, MySQL, and PHP) server. If haven’t already created a LAMP server, or just want to make sure that you have everything installed, take a look at our Hosting a Website guide. After you have a LAMP server running, read through the rest of this section to verify that you have the other prerequisites installed.

Installing PHP Extensions

Dolphin requires the following PHP extensions to be installed and enabled: mbstring, mysql, mysqli, curl, gd, xslt. Here’s how to install them:

1. Install the extensions by entering the following command:

   sudo apt-get install php5-mysql php5-curl php5-gd php5-xsl
   

2. Install imagemagick by entering the following command:

   sudo apt-get install imagemagick
   

3. Save your changes by restarting the Apache web server:

   sudo /etc/init.d/apache2 restart
   

The required PHP extensions for Dolphin are now installed on your computer.

Configuring PHP

You’ll also need to make some modifications to your php.ini file. Here’s how:

1. Open the php.ini file for editing by entering the following command:

   sudo nano /etc/php5/apache2/php.ini
   

2. If necessary, change the settings in that file, as shown below:

   File: /etc/php5/apache2/php.ini

   1 2 3 4 5 6 7

   memory_limit = 128M post_max_size = 32M upload_max_filesize = 16M register_globals = Off allow_url_fopen = On allow_url_include = Off magic_quotes_gpc = Off

3. Save the changes to the file by pressing Control-X, pressing Y, and then pressing Enter.

4. Save your changes by restarting the Apache web server:

   sudo /etc/init.d/apache2 restart
   

You have successfully modified your php.ini file for Dolphin.

Setting Up Email

To configure Dolphin to send email, you’ll need to install either Sendmail or Postfix. You should be able to use send-only exim as well.

Installing JRE

If you’d like to run the Boonex RMS (Ray Media Server), which is a required component for some of Dolphin’s features, like Flash chat, Flash instant messaging, boards, video recorder, video comments, you’ll also need to install JRE (Java Runtime Environment) version 1.6. Here’s how:

1. Install JRE on your Linode by entering the following command:

   sudo apt-get install openjdk-6-jre
   

2. RMS requires ports 1935, 1936, and 5080 to be open in your firewall. For more information, see the Securing Your Server guide and the Firewall reference manuals.

You have successfully installed JRE on your Linode.

Installing Dolphin

Now that you’ve installed the necessary prerequisites, we can start installing Dolphin. We’ll walk you through the process of downloading Dolphin, adding a new MySQL user and database, configuring permissions, running the install script, removing the installation directory, and finally logging in to the Dolphin admin panel.

Note

We assume that you followed the Hosting a Website guide. If you’re using a different DocumentRoot directive than /home/example_user/public/example.com/public for your virtual host, you’ll need to update the path to correctly reflect your DocumentRoot.

Downloading Dolphin

First, you need to download the latest Dolphin release. Here’s how:

Note

Be sure to check the Dolphin web site to verify that you are downloading the latest release.

1. Change to your virtual host directory by entering the following command, replacing example_user with your username and example.com with your domain name:

   cd /home/example_user/public/example.com/public
   

2. Create a new directory for Dolphin by entering the following command:

   mkdir dolphin
   

3. Change to the Dolphin directory by entering the following command:

   cd dolphin
   

4. Download the latest Dolphin release by entering the following command:

   wget http://get.boonex.com/Dolphin-v.7.0
   

5. Unzip the archive by entering the following command:

   unzip Dolphin-v.7.0
   

You have successfully downloaded Dolphin and unzipped the archive on your Linode.

Adding a MySQL User and Database

Next, you’ll need to add a MySQL user and database. Here’s how:

1. Log in to MySQL by entering the following command:

   sudo mysql -uroot -p
   

2. Enter your MySQL root password.

3. Create a database for Dolphin by entering the following command:

   create database dolphindb;
   

4. Create MySQL user for Dolphin by entering the following command, replacing password with the password for the new user:

   create user 'dolphin' identified by 'password';
   

5. Grant the new MySQL dolphin user access to the dolphin database by entering the following command:

   grant all privileges on dolphindb.* to 'dolphin';
   

6. Exit MySQL by entering the following command:

   quit;
   

You have successfully added a new MySQL user and created a database for Dolphin.

Configuring Permissions

Now you’ll need to adjust the permissions on Dolphin’s files. Here’s how:

1. Change to Dolphin’s directory in your virtual host by entering the following command, replacing example_user with your username and example.com with your domain name:

   cd /home/example_user/public/example.com/public/dolphin
   

2. To change the permissions, enter the following commands, one by one. Make sure you copy the entire commands - most of them are long:

   chmod 777 ./inc ./backup ./cache ./cache_public ./langs ./media/app ./media/images ./media/images/banners ./media/images/blog ./media/images/classifieds ./media/images/membership ./media/images/profile ./media/images/profile_bg ./media/images/promo ./media/images/promo/original ./tmp ./plugins/htmlpurifier/standalone/HTMLPurifier/DefinitionCache/Serializer ./plugins/htmlpurifier/standalone/HTMLPurifier/DefinitionCache/Serializer/HTML ./plugins/htmlpurifier/standalone/HTMLPurifier/DefinitionCache/Serializer/CSS ./plugins/htmlpurifier/standalone/HTMLPurifier/DefinitionCache/Serializer/Test ./plugins/htmlpurifier/standalone/HTMLPurifier/DefinitionCache/Serializer/URI

Media Server (RMS) Installation

Dolphin comes with a free Media Server software (formerly Ray Media Server - RMS), based on open-source Red 5. Media Server is required for some of the media streaming features of some Dolphin modules. Here’s how to install media server on your Linode:

1. We’ll be installing RMS into your /opt directory. Create a directory for the RMS install by entering the following command:

   sudo mkdir /opt/ray_server
   

2. Change to the new directory by entering the following command:

   cd /opt/ray_server
   

3. Download the latest Media Server for Linux by entering the following command:

   sudo wget http://get.boonex.com/RMS-LINUX-v.7.0.4
   

4. Unpack the archive by entering the following command:

   sudo tar -xvf RMS-LINUX-v.7.0.4
   

5. Move the files to ray_server by entering the following command:

   sudo cp RMS_7.0.4/* /opt/ray_server -R
   

6. Remove the archive and Media Server folder by entering the following commands, one by one:

   sudo rm -rf RMS_7.0.4
   sudo rm -rf RMS-LINUX-v.7.0.4
   

7. Open access.dat for editing by entering the following command:

   sudo nano /opt/ray_server/access.dat
   

8. Enter all of the domains you want to have access to your RMS installation. They should be listed one per line, as shown below. Do not include http:// or www:

   1 2 3

   /opt/ray\_server/access.dat > domain1.com domain2.com domain2.net domain3.com domain3.org

9. Save the changes to access.dat by pressing Control-X, and then pressing Y.

10. Open the red5.sh file for editing by entering the following command:

    sudo nano /opt/ray_server/red5.sh
    

11. Set the JAVA_HOME variable, as shown below:

    1	/opt/ray\_server/red5.sh

    JAVA_HOME=/usr/share/java;

12. Save the changes to red5.dat by pressing Control-X, and then pressing Y.

13. Open the rundaemon.sh file for editing by entering the following command:

    sudo nano /opt/ray_server/run_daemon.sh
    

14. Set the RAY_SERVER_PATH variable, as shown below:

    1	/opt/ray\_server/run\_daemon.sh

    RAY_SERVER_PATH=/opt/ray_server;

15. Save the changes to run_daemon.sh by pressing Control-Y, and then pressing Y.

16. Update the webapp.virtualHosts variable in the following files to your Linode’s IP address. Use nano to edit the files, like you did earlier:

    /opt/ray_server/webapps/board/WEB-INF/red5-web.properties /opt/ray_server/webapps/chat/WEB-INF/red5-web.properties /opt/ray_server/webapps/im/WEB-INF/red5-web.properties

17. Modify the permissions of all the .sh files in your Media Server directory by entering the following commands, one by one:

    cd /opt/ray_server
    sudo chmod -v 777 *.sh
    

18. Test your install by entering the following command:

    sudo ./red5.sh
    

19. A successful start should end with the following:

    [INFO] [Launcher:/installer] org.red5.server.service.Installer - Installer service created

20. If the start was successful, you can use the Boonex Media Server Tester to verify that your RMS install is working properly. If you get “NetConnection.Connect.Success”, everything is working.

Note

If you receive “NetConnection.Connect.Failed”, make sure you have ports 1935 and 1936 open in your firewall. For more information, see the Securing Your Server guide and the Firewall reference manuals.

21. If your test was successful, hold Control and press C to stop red5.sh.

22. Now you can start RMS as a background process by entering the following command:

    sudo ./run_daemon.sh
    

You have successfully installed RMS on your Linode.
