3. Add the first Crowd node to your load balancer

ロードバランサはノード間のトラフィックを分散させます。ノードが動作を停止すると、残りのノードがワークロードを引き継ぐため、ユーザーは気付くこともありません。

First, add your load balancer as a trusted proxy server in Crowd. See Configuring Trusted Proxy Servers.
最初のノードをロードバランサに追加します。
Restart the node, and then try opening different pages in Crowd. If the load balancer is working properly, you should have no problems with accessing Crowd.
In Crowd, go to > Clustering. The node should be listed as part of the cluster.

If your load balancer supports health checks, configure it to perform a check on http://<crowd-node>:8095/<context-path>/status, where <crowd-node> is the node's hostname or IP address, and <context-path> is the Crowd's context path (e.g. /crowd). If the node doesn't respond with a 200 OK response within a reasonable time, the load balancer shouldn't direct any traffic to this node.
After you've added the node to the load balancer, configure the Crowd's base URL to also point to the load balancer. Go to > General, and enter the URL of your load balancer as Base URL.
