Word. Press and Etherpad with Blue. Mix and Docker
Our aim is to run on Blue. Mix containers (now in beta) these two famous services In the Blue. Mix dashboard, we click create a container, we then follow the steps, paste a SSH public key, and wait for the creation to be confirmed. Then, we connect to the container using the SSH private key (I used putty as a SSh client on windows). Once connected as root, we are ready to work with our container.
Word. Press is a CMS (kind of blog manager) widely used and easy to configure. To run Word. Press, we will need Apache, as a web server, My. SQL for the database, and php will be the scripting language. Finally, we will install and run Word. Press.
Apache Installation Our containers are based on ubuntu 14. 04, we will be able to use its packet manager, called apt. The command is : apt-get update && apt-get install apache 2 && service apache 2 start
My. SQL installation apt-get install mysql-server php 5 -mysql service mysql start mysql_install_db mysql_secure_installation The installation script will run, and questions will be asked through the terminal (which password, which user …? )
Php install (version 5 used) apt-get install php 5 libapache 2 -mod-php 5 -mycrypt php 5 -gd libssh 2 -php We then edit (for example with nano) /etc/apache 2/modsenabled/dir. conf We switch the order of index. html and index. php,
Creation of the database mysql –u root –p CREATE DATABASE wordpress; CREATE user wordpress_user@localhost IDENTIFIED BY ‘our_password’; GRANT ALL PRIVILEGES ON wordpress. * TO wordpress_user@localhost; FLUSH PRIVILEGES; exit
Wordpress download cd ~ wget http: //wordpress. org/latest. tar. gz tar xzvf latest. tar. gz
Wordpress configuration cd. /wordpress cp wp-onfig-sample. php wp-config. php nano wp-config. php define('DB_NAME', 'wordpress'); define('DB_USER', 'wordpress_user'); define('DB_PASSWORD', ‘our_password');
Linking apache and wordpress rsync -av. P ~/wordpress/ /var/www/html/
First launch We access 129. 41. 227. 85 (or the address given by bluemix)
Etherpad is a collaborative tool used to edit text, very similar to a Google Doc We will use etherpad lite, that works with nodejs, and Ngin. X will take care of the network.
Installation of node. js Etherpad requires a given version of node. js (between 0. 10 and 0. 12). I then chose to download it directly from the node. js website. Wget http: //nodejs. org/dist/v 0. 12. 4/node-v 0. 12. 4. tar. gz Tar xzvf node-v 0. 12. 4. tar. gz. /configure Make #This is the compilation step, it may take time Make install Node –v checks the version of node installed (0. 12 for me).
etherpad lite installation Mkdir etherpad_folder Cd etherpad_folder git clone https: //github. com/etherpad-lite. git. /bin/install. Dep. sh If dependencies are not up-to-date, there are errors : we must update. We can edit the address: ~/etherpad_folder/etherpadlite/settings. json to switch from 0. 0 to 127. 0. 0. 1.
Launching through a screen When etherpad is running, there is no way to type other commands. Thus, we will use what is called a screen, that allows to have more tha none terminal window. If it is not already installed: apt-get install screen Then : screen # we have a blank new window ~/dossier_etherpad/etherpad-lite/bin/run. sh #launching We go back to the main terminal by using the shortcut : press Ctrl and a, then d. To go back to the screen, the command is screen rd
What is the use of nginx? Through wget 127. 0. 0. 1: 9001, we check that etherpad works well, (we get an index. html file, its beginning is available with head index. html). We want to access the l’etherpad through the web, we shall use a proxy.
Installation of nginx We install it through : apt-get install -t wheezy-backports nginx We create te file : /etc/nginx/sites-available/etherpad And copy the configuration (next slide) Then, we create a symbolic link to the active configuration : ln -s /etc/nginx/sites-available/etherpad /etc/nginx/sites-enabled/ Then, we reload the server and (re)start the service nginx reload && service nginx (re)start
Ngin. X configuration (you can simply copy/paste it with a few modifications) server { listen 80; // default web http port, sometimes may be 8080 server_129. 41. 238. 118; //replace it with YOUR public IP address, people will access the server through it access_log /var/log/nginx/etherpad. access. log; error_log /var/log/nginx/etherpad. error. log; location / { proxy_pass http: //127. 0. 0. 1: 9001; //exchanges data with the etherpad proxy_set_header Host $host; proxy_buffering off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_http_version 1. 1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $connection_upgrade; } } map $http_upgrade $connection_upgrade { default upgrade; '' close; }
We may now access etherpad through a web browser, and create an active sheet. If there is a problem with the nginx configuration, we get a http 502 bad gateway error.
