Lua is a flexible programming language frequently used for scripting.
By default, Lua version 5.1 is installed on reseller and shared hosting accounts. If you have a managed VPS or managed Flex Dedicated Server, please open a ticket on the Customer Portal at https://my.a2hosting.com and we can install it for you.
If you have a Cloud VPS, semi-managed VPS or Flex Dedicated Server account, you can install Lua by using the package manager for your Linux distribution.
