Verifying the Cluster

The following operations must be performed in a new window, and the window for starting the etcd cluster cannot be closed.

Go to the /usr/local/etcd/bin directory and check the etcd version.
```
cd /usr/local/etcd/bin
./etcd --version 
```
View the cluster member list.
```
./etcdctl member list 
```
Check the condition of cluster members. (Replace the IP addresses in the following command with the actual IP addresses.)
```
./etcdctl endpoint health --endpoints="10.208.71.111:2379,10.208.107.205:2379,10.208.72.182:2379"
```
etcdctl is the CLI client for etcd.

Check the leader of the cluster. The node whose IS LEADER value is true is the leader node.

/usr/local/etcd/bin/etcdctl -w table --endpoints="10.208.71.111:2379,10.208.107.205:2379,10.208.72.182:2379" endpoint status

Verify that data can be inserted into node 1 (the leader).

/usr/local/etcd/bin/etcdctl put age 25
/usr/local/etcd/bin/etcdctl put name angel

Query the data you inserted (in step 5) on node 1.

/usr/local/etcd/bin/etcdctl get age
/usr/local/etcd/bin/etcdctl get name
