ProxMox Cluster - Soup-to-Nutz

aka what i did to get from nothing to done.

note: these are designed to be primarily a re-install guide for myself (writing things down helps me memorize the knowledge), as such don't take any of this on blind faith - some areas are well tested and the docs are very robust, some items, less so). YMMV

Go has excellent build tools that mitigate the need for using make. For example, go install won't update the target unless it's older than the source files.

However, a Makefile can be convenient for wrapping Go commands with specific build targets that simplify usage on the command line. Since most of the targets are "phony", it's up to you to weigh the pros and cons of having a dependency on make versus using a shell script. For the simplicity of being able to specify targets that can be chained and can take advantage of make's chained targets,

Nginx FastCGI response buffer sizes

By default when Nginx starts receiving a response from a FastCGI backend (such as PHP-FPM) it will buffer the response in memory before delivering it to the client. Any response larger than the set buffer size is saved to a temporary file on disk.

This process is outlined at the Nginx ngx_http_fastcgi_module page manual page.

• Introduction
• Determine actual FastCGI response sizes
• Setting the buffer size
• Verifying results
