Running your WordPress blog on WSO2 App Cloud
WSO2 App Cloud is now supporting Docker base PHP applications. In this blog post I will describe how to install a WordPress blog in this environment. In order to setup a WordPress environment we need to have two things;
- Web server with PHP support
- MySQL database
If we have both of these we can start setting up WordPress. In WSO2 App Cloud we can use the PHP application as the WordPress hosting web server which is a PHP enabled Apache web server docker image. Also it provides a database service where you can easily create and manage MySQL databases via the App Cloud user interface (UI).
For the moment WSO2 App Cloud is on beta therefore these docker images will have only 12h of lifetime with no data persistence in the file storage level. Data on MySQL databases will be safe unless you override. If you need more help don’t hesitate to contact Cloud support.
Creating PHP application
Signup or signin to WSO2 App Cloud via http://wso2.com/cloud. Then click on the “App Cloud beta” section.
Then it will redirect you to the App Cloud user interface. Click on ‘Add New Application’ button on the left hand corner.
This will prompt you to several available applications. Select ‘PHP Web Application’ box and continue.
Then it will prompt you a wizard. In that give a proper name and a version to your application. Name and version will be use to generate the domain name for your application.
There are several options that you can use to upload PHP content to this application. For the moment I will download the wordpress-X.X.X.zip file from the wordpress site and upload it to application.
In the below sections of the UI you can set the run time and container specification. Give the highest Apache version as the runtime and use minimal container speck as wordpress does not require much processing and memory.
If the things are all set and the file upload is complete click on ‘Create’ button. You will get the following status pop-up when you click the create button and it will redirect you to the application when its complete.
In the application UI note the URL. Now you can click on the ‘Launch App’ button so that it will redirect you to your PHP application.
Newly installed WordPress site will be like this.
Now we need to provide database details to it. Therefore, we need to create database and a user.
Go back to the Application UI and click on ‘Back to listing’ button.
In that UI you can see a button in the top left hand corner called ‘Create database’. Click on that.
In the create database UI give a database name, database user name and a password . Password need to pass the password policy so you can click on ‘Generate password’ to generate a secure password easily. By the way of you use generate password option make sure you copy the generated password before you proceed with database creation. Otherwise you may need to reset the password.
Also note that database name and database user name will append tenant domain and random string accordingly to the end of both. Therefore, those fields will only get few number of input characters.
If all set then click on ‘Create database’ button to proceed. After successfully creating the database it will redirect you to a database management user interface like following.
Now you can use those details to login to the newly create mysql database as follows;
$ mysql -h mysql.storage.cloud.wso2.com -p’’ -u
$ mysql -h mysql.storage.cloud.wso2.com -p’XXXXXXXXX’ -u admin_LeWvxS3l wpdb_thilina
If the database creation is successful and you can login to it without any issue we can use those details to configure WordPress.
Go back to the WordPress UI and click on ‘let’s go’ button. It will prompt to a database configuration wizard. Fill those fields with the details that we got from the previous section.
If WordPress application can successfully establish a connection with the database using your inputs it will prompt you to a UI as follows.
On that click on ‘Run the install’. Then WordPress will start populating database tables and insert initial data to the given database.
When its complete it will ask for some basic configurations like the site title, admin user name and passwords.
Click on ‘Install WordPress’ after filling those information. Then it will redirect you to the WordPress admin console login page. Login to that using the username and password gave in the previous section.
So now WordPress is ready to use. But the existing URL is not very attractive. If you have a domain you can use it as the base URL of this application.
Setting custom domain (Optional)
IN the application UI click on the top left three lines button shown in the following image.
It will show some advance configuration that we can use. In that list select the last one ‘Custom URL’ option.
It will prompt you following user interface. Enter the domain name that you are willing to use.
But before you validate make sure you add a DNS CNAME to that domain pointing to you application launch URL.
Following is the wizard that I got when adding the CNAME via Godaddy. This user interface and adding CNAME options will be different for you DNS provider.
You can validate the CNAME by running ‘dig’ command in Linux or nslookup in windows.
If the CNAME is working click on ‘Update’.
If that is successful you will get the above notification and if you access that domain name it will show your newly created WordPress blog.
