MySQL Database Service Webinar - Installing WordPress in OCI with MDS
2 likes291 views
The document outlines the steps to install WordPress on Oracle Cloud Infrastructure (OCI) using the MySQL Database Service. This includes creating a VCN with public and private subnets, creating a MySQL Database Service instance, launching a compute instance in the public subnet to host WordPress, installing WordPress and required software like PHP, and configuring security settings on the compute instance and in OCI like firewall rules and SELinux policies.
![Installing WordPress: download & install
Now we will download WordPress and install it on the webroot:
[opc@mywordpress ~]$ cd /var/www/
[opc@mywordpress www]$ sudo wget https://wordpress.org/latest.tar.gz

To create a database and a dedicated user for WordPress, we need to install a MySQL client
on the compute instance. We will use MySQL Shell:
[opc@mywordpress ~]$ sudo rpm -ivh
