What is the difference between the two installation types of the Miva Empresa Virtual Machine on a UNIX/Linux platform?
There are several different ways that one can install the Miva Empresa Virtual Machine on a UNIX/Linux platform . You'll want to understand these differences before installing the Miva Empresa Virtual Machine on your server.
First off, there are two different installation Modes: Server-Safe Mode and Standard Mode.
â€¢ Server-Safe Mode - With this installation mode, the Miva Empresa Virtual Machine binary will go into a global cgi-bin that all sites on the server will be able to access to run their Mivascript applications. With this mode, you only need to instal lthe Miva Empresa Virtual Machine once. It also makes upgrading easier when new releases come out as there is only one set of files to update.
â€¢ Standard Mode - With this installation mode, the Miva Empresa Virtual Machine binary is installed into each site's private cgi-bin. With this mode, you will need to install multiple instances of the Miva Empresa Virtual Machine for each site on the server.
However, since root level privileges are not necessary for this installation, the site user is able to install the Miva Empresa Virtual Machine on their own and can take care of updates themselves.
In addition to these two installation modes, there are two instalaltion Methods: 3.x configuration method and 4.x configuration method.
â€¢ 3.x configuration method - This method uses a mivavm.conf file for the Miva Empresa Virtual Machine configurations. This method may be a bit slower as the server needs to access a separate file for the virtual machine settings.
â€¢ 4.x configuration method - This method uses SetEnv variables inside the Apache Configuration File for the Miva Empresa Virtual Machine configurations. Since these variables are loaded at the same time as Apache, the Virtual Machine should run faster.
There are certain limitations based on which installation mode you choose (Server-Safe or Standard). The guidelines are below:
â€¢ Server-Safe Mode - can use either the 3.x configuration method or the 4.x configuration method.
â€¢ Standard Mode - can only use the 3.x configuration method.
