Can es_host configure multiple nodes' IP in config.yml? I have 3 ES nodes，thanks

I don't think it can be done with the current Elast Alert. The following pull request seems to be relevant.

simple solution is to install a lightweight load balancer (like nginx or haproxy) and redirect your requests to your elasticsearch nodes. Just be sure your index settings are correctly spreading replicas of your shards accross your nodes because if the LB query a elastic node but doesn't contain all the data you needs, you will not see everything if the datas are spreads between the nodes

No, you don't need to install it multiple places, nor do you need to declare all the node names. All you need is direct connectivity to a SINGLE node.

Please use haproxy in front of elasticsearch . This helps to accomplish ha mode for elastalert.

I recommend haproxy. It's super simple to set up a reverse proxy for Elasticsearch to do load balancing.
