Apache httpd has been around for a long time but a lot of people now have first experiences with nginx.

This is a simple guide to help translate some nginx concepts into apache configs

introduction & basics

nginx is only event-driven
Apache can be event-driven with mpm_event

nginx mostly uses static linking for modules whereas apache mostly uses dynamic linking for modules
both servers support both methods, but the common defaults differ; this is why you will find a lot of

#git fetch and git checkout always make changes to files in .git
#this causes docker, for example, to uncache the layer if you are putting your source code into the container

so you want to learn erlang

erlang is great. It is interesting, fun, cool, everything you want. However, it can be difficult to get started using it because all of the examples are using the interactive shell.

This is a small guide to get a few simple bootstrap things out of the way.

This is not about erlang syntax or idioms, it is how to use it.

getting erlang

0. Ensure there are no tlogs
1. take backups

• note the "config name" from tree view for each collection you delete
• note what the createNodeSet values will be (action=CLUSTERSTATUS&wt=json)

2. delete everything via collection api

• repeat until "tree view" in solrcloud admin shows empty collections

3. shutdown java globally and delete instance dirs if they are still around (they often are)
4. startup a single node
5. create collections like so: action=CREATE&name=collection1&shards=shard1,shard2&collection.configName=see-earlier-step&numShards=2&maxShardsPerNode=2&createNodeSet=also-from-info-api

• you can get createNodeSet value from action=CLUSTERSTATUS&wt=json
