KUSANAGI Initialization

KUSANAGI Initialization

Once you have logged in to the virtual machine, you can perform initialization.

For initialization we will use specialized “KUSANAGI commands”.

“KUSANAGI commands”are designed for KUSANAGI only and can be used for web server switching, cache control and other features after initialization.

The following steps explain the procedures of getting KUSANAGI ready for WordPress.

1. Start initialization

First, use yum to update your CentOS and KUSANAGI system before initializing.
Enter the following command to begin the update.

# yum --enablerepo=remi,remi-php56 update -y

Once the update is completed, continue the steps to initialization.

Use the following command to reboot the server.If you are using Microsoft Azure, restart the virtual machine using Microsoft Azure portal.

# reboot

You will be logged out so please log in again and switch to the root user.

Next, we will set or change the user passwords of Linux and databases in the virtual machine.
Enter the following command to start.

# kusanagi init  [options]

2.The creation of the TLS host key file

Create the TLS session key file and parameter files to use DH(Diffie-Hellman) key exchange.
The file will be created under /etc/kusanagi.d/ssl ,it will not be recreated if the file is already there.
please be aware of that it will takes several minutes to create the file according to the performance of the machine.
