-# Installing OpenSearch
-## Prerequisites and Setup
-  * uses Docker; which is why i installed Docker and wrote the [[Docker]] wiki yesterday
-  * [source](https://opensearch.org/docs/latest/getting-started/quickstart/)
-  * `sudo swapoff -a`
-    * disables memory-paging and swapping
-  * `sudo vi etc/sysctl.conf` (leading `/` removed because `mod_security` is stupid)
-    * actually it's `etc/sysctl.d/10-map-count.conf`
-    * `vm.max_map_count=262144`
-      * Set max map count to 262144
-  * `sudo sysctl -p`
-    * reload kernel parameters
-## Install Steps
-  * `curl -O https://raw.githubusercontent.com/opensearch-project/documentation-website/2.19/assets/examples/docker-compose.yml`
-    * download the example docker-compose (which is a functional OpenSearch cluster)
-  * `export OPENSEARCH_INITIAL_ADMIN_PASSWORD=<admin-password>`
-    * **NOTE** without this value the opensearch nodes will refuse to start!
-  * `docker compose up -d`
-    * start the docker-compose cluster as background process (`-d` = detached)
-    * will download about 12 containers (two of which are 968MB and 350MB); takes a while first time
-## Testing Steps
-  * `curl https://localhost:9200 -ku admin:<admin-password>`
-    * response should confirm that the install worked
-  * http://localhost:5601/ should respond with dashboards and such
-    * change admin-password if you like at this point
-## Shooting Trouble
-  * `[ConnectionError]: getaddrinfo ENOTFOUND opensearch-node1`
-    *
