# luapower vps installation

needs 1GB RAM; Ubuntu 18.04


## functionality

  * luapower-related
    * luapower.com website (openresty+luapower)
    * luapower.com forum (nodebb+redis)
    * mirror for compiler tools (static files)
    * apt mirror for ubuntu's "test toolchain" PPA
    * git mirror for luapower repos (git-mirror; currently empty)
  * personal stuff
    * mokingburd.de (static website)
    * capr.github.io (static website)
    * luapower.com/oldbeat (static website)

## crontab

  * luapower source code
    * pull all packages (hourly, so that docs are updated and for code search; we have github hooks on all repos that trigger pulling, so this is just a safety measure)
  * luapower bundle
    * update/push luapower-all (each half hour, so that master.zip from the download button reflects the current state of the code)
    * release-tag luapower-all (daily, so that we can download old releases)
    * download github.com/luapower/luapower-all/archive/master.zip (every day, so that its reported size on the download button reflects the actual size of the archive)
  * forum
    * backup the redis db and any new files (plugins, customization, etc.) to the `forum` repo (daily)
