How to Deploy a WordPress Instance on Alibaba Cloud
Overview This blog explains how to set up a WordPress instance with an Apache web server on Alibaba Cloud ECS Ubuntu 14.04.
About WordPress WordPress is one of the world's most popular Content Management Systems (CMS) to manage online blogs and websites. WordPress has witnessed incredible user adoption over the years and is a great choice for getting a website up and running quickly. WordPress allows you to build a website on top of a MySQL backend with PHP processing.
Getting Ready Before we can start, you will need to complete a couple of important steps to configure your server. You will need to first create a non-root user with sudo privileges here, and have a LAMP (Linux, Apache, MySQL and PHP) stack installed on your Alibaba Cloud ECS instance.
Deploying WordPress Let's now go through step-by-step how to deploy WordPress on Alibaba Cloud ECS.
Step 1: Launch a Linux instance with ECS
Execute the following steps to launch an Alibaba Cloud ECS instance for your Linux machine:
- Login to your account through the Alibaba Cloud Management Console (https://ecs.console.aliyun.com).(https://partners-intl.console.aliyun.com/#/ecs). After logging in you will be redirected to the following dashboard.
2. Navigate to ‘Elastic Compute Service’ under the ‘Products & Services’ section. You will be redirected to the ECS overview dashboard. Click on ‘Instances’ in the sidebar menu to navigate to the Instances dashboard.
3. After creating an instance, choose your preferred payment method as per your requirements. You can decide to opt for a Starter Package or Advanced Purchase. Choose the Datacenter Region and Availability Zone to launch your ECS instance. If you specify the Region but do not specify the Availability Zone, then the instance will be placed in the default zone.
4. Under ‘Choose Instance Type’ select the Generation. Different Generation types offer different configuration and computing power. Select Network Type between Classic Network or VPC depending on your needs. Next, select Network Billing Type.
5. Choose Ubuntu or another Linux server image to launch the Linux server. Also, select the version of the image using the dropdown tab as per your requirements and then select the desired storage type.
6. An option to set up your server security by setting a password will be given. You may choose to set the password or set it later from the Management Console.
7. Check the overview of your purchase configuration and click Activate to confirm and launch your server.
8. Your launched instances will appear in the Instances section
That's how you can easily launch an ECS instance with Linux Operating System using the Management Console.
Step 2: Create a MySQL Database and User for WordPress
Related Alibaba Cloud Products: Alibaba Cloud ApsaraDB for RDS WordPress makes use of a relational database to store and manage sites and user data. We will use MySQL here in the blog, but for production environment, we can use Alibaba Cloud ApsaraDB for RDS, which is an on-demand database service that frees you from the administrative labor of database management and leaves you with more time to focus on your core business. ApsaraDB for RDS is a ready-to-use service offered on MySQL, SQL Server, and PostgreSQL. RDS handles routine database tasks such as provisioning, patch up, backup, recovery, failure detection and repair. We have MySQL installed, but we need to create a database and user for WordPress. To get started, log into the MySQL root account using this command:
Here, you need to enter the password of your MySQL root account that you had set at the time of software installation. Upon entering the password, you will be given a MySQL shell. Let’s also create a separate database for WordPress. You can name it whatever you like, but here we will call it “wordpress”. Use the following command:
Welcome to aliyun Elastic Compute Service! root@iZt4n0drrwgfgq36vp3glgZ:~# mysql - u root -p
Note: Every MySQL statement should end in a semicolon (;). Make sure this is not the cause for any errors. Now, for operating on our new database, we need to create an exclusive MySQL user account. Creating one-function databases and accounts is advisable from management and security standpoints. Let’s call the new account “wordpress user” and assign “password” for the password field. The values for your user and password fields should be chosen wisely. Now create a user via this command:
mysql> CREATE DATABASE wordpress;
Now we have a database and a user account specifically for WordPress. However, the user does not have access to the database yet. To grant database access to the user account, enter the following command:
mysql> CREATE USER wordpressuser@localhost IDENTIFIED BY ‘password’ ; Query OK, 0 rows affected (0.00 sec)
This command grants database access to the user account. Now, to flush the privileges so that the current MySQL instance is aware of the recent privilege changes that we have made, we have to enter the following command:
mysql> GRANT ALL PRIVILEGES ON wordpress. TO wordpressuser@localhost;
Now, this part is done. Use “exit” to come out from the MySQL prompt as follows:
mysql> FLUSH PRIVILEGES;
You should now be back to your regular command prompt.
Step 3: Download WordPress
Next, download the actual WordPress files from the project's website. Fortunately, WordPress always links the recent most stable version of their software to the same URL. Get the latest version of WordPress by using the following command:
This downloads a compressed file containing the archived directory contents of the WordPress files to our home directory. Use the following command to extract the files required for rebuilding the WordPress directory:
root@iZt4n0drrwgfgq36vp3glgZ:~# wget http://wordpress.org/latest.tar.gz
This command creates a directory called “wordpress” in your home directory. Now, post executing these commands we will download a few more required packages. You can get these directly from Ubuntu's default repositories after you update your local package index:
root@iZt4n0drrwgfgq36vp3glgZ:~# tar xzvf latest.tar.gz
This facilitates working with images and also allows you to install plugins and update portions of your site using your SSH login credentials.
root@iZt4n0drrwgfgq36vp3glgZ:~# sudo apt-get updateroot@iZt4n0drrwgfgq36vp3glgZ:~# sudo apt-get install php5-gd libssh2-php
Step 4: Configure WordPress
We will do most of the configuration through a web Interface later on. However, we do need to do some work from the command line before we can get this up and running. Let’s start by moving into the WordPress directory that we just unpacked, using the following command:
By default, a sample configuration file that closely matches the configuration we need is included. However, in order for WordPress to recognize the file, we need to copy it to the default configuration file location. To do so, use the following command:
root@iZt4n0drrwgfgq36vp3glgZ:~# cd ~/wordpress
Now that we have a configuration file to work with, let's open it in a text editor:
root@iZt4n0drrwgfgq36vp3glgZ:~/wordpress# cp wp-config-sample.php wp-config.php
As mentioned earlier, this file meets most of our needs already with some modifications to the parameters that hold our database information. Search the settings for DB_NAME, DB_USER, and DB_PASSWORD for WordPress to correctly connect to and authenticate the created database. We need to populate these parameters with the information for the database created. It would be visible as shown below:
root@iZt4n0drrwgfgq36vp3glgZ:~/wordpress# vi wp-config.php
Change only the highlighted values, save and close the file once you finish.
Step 5: Copy Files to the Document Root
After we have configured our application, we must then copy it to Apache's document root where it can be served to our website’s visitors. File transfer between directories using the rsync command can be done in an easy and reliable manner. This preserves permissions and offers data integrity features as well. The document root location is /var/www/html/. We can transfer the WordPress files there by typing:
This copies all of the contents from the directory you unpacked to the document root in a safe manner. Next, go to the document root to make a few final changes to the permissions.
root@iZt4n0drrwgfgq36vp3glgZ:~/wordpress# sudo rsync -avP ~/wordpress/ /var/www/html/
Change the ownership of files for increased security. We want to give user ownership to regular, non-root user (with sudo privileges) that you plan to use for interacting with your site. This could be a regular user, or we can create an additional user. Next perform all the actions from the root account. Assign correct ownership on your uploads directory so that the owner can upload all kinds of content to your site. Currently, the permissions are too restrictive. Let us first create the uploads directory manually under wp-content directory at our document root, making it the parent directory for our content:
root@iZt4n0drrwgfgq36vp3glgZ:~/wordpress# cd /var /www/html
root@iZt4n0drrwgfgq36vp3glgZ:/ var /www/html# mkdir /var/www/html/wp-content/uploads
Step 6: Complete Installation through the Web Interface

In your web browser, go to your server’s domain name or public IP address: http://server_domain_name_or_IP On the WordPress initial configuration page, create an initial administrator account:
Fill out the required information and the administrative account you wish to create. (Note: The user must note down his/her password to login again, as the reset option will not work at this stage as the email ID has yet to be configured.) Once finished, click on the install button at the bottom.
Once you fill in your account information you will be directed to the WordPress interface:
Your WordPress instance is now up and running on your ABC ECS (Ubuntu 14.04).
