1. Log in as the “jenkins” user on the Master Node:

$ cd ~

2. Create a directory for WordPress configuration files (you can choose any name):

$ mkdir wp-config-files

3. Mount the EFS (Elastic File System) created for config files: Replace fs-011a40c8f24e5b94d.efs.ap-south-1.amazonaws.com with your actual EFS endpoint.

$ sudo mount -t nfs4 -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport fs-011a40c8f24e5b94d.efs.ap-south-1.amazonaws.com:/ /home/jenkins/wp-config-files

4. Verify that the mount was successful:

$ df -k

5. Navigate to the wp-config-files directory:

$ cd wp-config-files

6. Install Git: (if not already installed)

$ sudo yum install -y git

7. Download the required YAML files for deploying WordPress:

$ git clone https://github.com/AvangelsTech/simple-wordpress-files.git .

 

Next proceed to set up the Worker node for WordPress data files.

1. Log in to the Worker Node as the “jenkins” user:

$ cd ~

2. Create a directory for WordPress data files (you can choose any name):

$ mkdir wp-data-files

3. Mount the EFS (Elastic File System) created for the WordPress data files: Replace fs-09b70377fe373b9f6.efs.ap-south-1.amazonaws.com with your actual EFS endpoint.

$ sudo mount -t nfs4 -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport fs-09b70377fe373b9f6.efs.ap-south-1.amazonaws.com:/ /home/jenkins/wp-data-files

4. Verify that the mount was successful:

$ df -k

5. Create two additional directories: “html” and “mysql”:

$ cd /home/jenkins/wp-data-files
$ mkdir html mysql

6. Set ownership for the directories:

$ sudo su
# chown jenkins:jenkins html
# chown jenkins:jenkins mysql
# exit
$ exit

 

The directory setup on both the Master node and Worker node is now complete. 

1. Log in to the Master Node as the “jenkins” user:

$ cd ~/wp-config-files

2. Navigate back to the home directory:

$ cd ~

3. Deploy the WordPress and MySQL pods, creating the necessary services:

$ kubectl create -f wp-config-files/

1. Log in to the MySQL pod on the Master Node:

$ kubectl exec -ti wordpress-mysql-0 /bin/bash

2. Access the MySQL prompt:

# mysql -u root -p

You’ll be prompted to enter the password.

3. Create a new database named “wordpress”:

mysql> create database wordpress;

4. Exit the MySQL prompt:

mysql> exit

5. Exit the pod:

bash-4.2# exit

6. Finally, stop the WordPress deployment. To to that, delete the deployment (e.g., wp-config-files) to apply changes to WordPress data files.

$ kubectl delete -f wp-config-files/

1. Log in to the Worker Node as the “jenkins” user. This is where the WordPress and MySQL data files reside.

2. Edit the “wp-config.php” file. This file contains essential configurations for WordPress. Make sure to keep it secure.

3. Modify the following parameters in “wp-config.php” based on your Kubernetes deployment YAML file:

• DB_NAME: The name of the WordPress database (e.g., “wordpress”).
• DB_USER: The database username (e.g., “root”).
• DB_PASSWORD: The database user’s password (e.g., “admin”).

4. Ensure that the WORDPRESS_DB_PASSWORD matches the password provided in the “secret.yaml” file. Remember that the password in “secret.yaml” is encoded in base64.

1. Log in as the “jenkins” user and navigate to the directory containing your deployment YAML files (e.g., “wp-config-file”).

2. Recreate the WordPress deployment using the following command:

$ kubectl create -f wp-config-file

This action will apply the database, database user, and database password values defined in Step 5 to the “wp-config.php” file.

3. Access WordPress via a web browser by pasting the public IP address of your Worker Node EC2 instance along with the port number:

http://<public-ip-address-worker-node>:32010

Replace <public-ip-address-worker-node> with the actual public IP of your EC2 instance.

4. If everything is set up correctly, you’ll see the WordPress screens. Follow the prompts and input the necessary data (you can choose your preferred language).
