Root-directory

The <root-directory> directive specifies the root of the current Environment. In a <host>, it specifies the parent directory for any <access-log>, <web-app-deploy>, or any child <web-app>.

<host>

In general, you should configure a <root-directory> for each virtual host.

If you deploy your virtual hosts with <host-deploy>, then the <root-directory> is already configured for you.
