Creating a Ghost site with Openstack-Flex
Welcome! In this blog post we are going over using Openstack-Flex to deploy Ghost. If you havent used ghost before and would like more information about it please visit their website using the link here
Getting Started:
First you will need to set up your clouds.yaml file to be able to complete the next steps. More information about that can be found here.
Creating our Openstack-Flex Server
Fist we are going to create our Flex router.
Second we are we wil create our flex network
Next we are going to set our router's external gateway to PUBLICNET to grant access to the internet.
Now we are going to set up our subnet, you can choose between ipv4 and ipv6. The ip range is also up to you. For the DNS name server you will need to ping cachens1.sjc3.rackspace.com and cachens2.sjc3.rackspace.com.
ping cachens1.sjc3.rackspace.com -c2
ping cachens2.sjc3.rackspace.com -c2
openstack --os-cloud {cloud_name} subnet create --ip-version 4 --subnet-range 172.18.107.0/24 --dns-nameserver 216.109.154.188 --dns-nameserver 216.109.154.189 --network flex-network flex-subnet
Connect the subnet to our flex-router
Now we need to create our security group, this is the group which specify the network access rules. For our example now we are only going to allow SSH access.
openstack --os-cloud {cloud_name} security group rule create --ingress --remote-ip 0.0.0.0/0 --dst-port 22 --protocol tcp flex-sg
Now we need to create our floating ip.
Note
Save this ip for later we will need to connect it to our server.
Now we are going to create our Public and Private ssh keys so we can securely connect to our server. I am naming my key wordpress-key
This will prompt you store and name your private key. I did something like this /home/{username}/.ssh/flex-key.After that we will create our public key using the command below then we will assign it using the the openstack cli tools.
ssh-keygen -f ~/.ssh/flex-key -y > ~/.ssh/flex-key.pub
openstack —os-cloud {cloud_name} keypair create --public-key ~/.ssh/flex-key.pub flex-key
Now we create our server! This should include the flavor you'd like to use, the image, memory, network, key-name, and security group for this example.
openstack --os-cloud {cloud_name} server create --flavor m1.medium --image Ubuntu-22.04 --boot-from-volume 40 --network flex-network --key-name flex-key --security-group flex-sg flex-server
Assigning our floating ip. We can do this by adding it to our port for the server. If you get the fixed ip from our newly create server you can find the port ID by searching through the port list.
openstack --os-cloud {cloud_name} port list
openstack --os-cloud {cloud_name} floating ip set --port {port id} {floating-ip}
SSH into your new Server!
Deploying our Ghost website on our Openstack-Flex server
Once we have created our Openstack-Flex Server we will want to make sure everything is up to date.
Next we need to install nginx
Next we need to enable nginxStart nginx
Next we install Mysql
Next we need to use mysql and create our wordpress database with our username and password. Please create your own personal username and password.
CREATE DATABASE ghost-db;
CREATE USER 'openstack-flex'@'localhost' IDENTIFIED BY 'pass';
GRANT ALL PRIVILEGES ON ghost-db.* TO 'openstack-flex'@'localhost';
FLUSH PRIVILEGES;
EXIT;
Next step is to install Node.js
Our last step is to install Ghost
sudo mkdir -p /var/www/directory-name
sudo chown -R {username}:{username} /var/www/ghost/
sudo chmod -R 755 /var/www/ghost/
cd /var/www/ghost
Answer the configuration question and when that is complete you can reach the setup page for your website. It should look like this.
