Welcome to the SolrCloud example!

This interactive session will help you launch a SolrCloud cluster on your local workstation.
To begin, how many Solr nodes would you like to run in your local cluster? (specify 1-4 nodes) [2]: 

Ok, let's start up 2 Solr nodes for your example SolrCloud cluster.
Please enter the port for node1 [8983]: 

Please enter the port for node2 [7574]: 

Creating Solr home directory /opt/solr-8.11.1/example/cloud/node1/solr
Cloning /opt/solr-8.11.1/example/cloud/node1 into
   /opt/solr-8.11.1/example/cloud/node2

Starting up Solr on port 8983 using command:
"bin/solr" start -cloud -p 8983 -s "example/cloud/node1/solr" -force

Waiting up to 180 seconds to see Solr running on port 8983 [-]  
Started Solr server on port 8983 (pid=1214969). Happy searching!

    
Starting up Solr on port 7574 using command:
"bin/solr" start -cloud -p 7574 -s "example/cloud/node2/solr" -z localhost:9983 -force

Waiting up to 180 seconds to see Solr running on port 7574 [/]  
Started Solr server on port 7574 (pid=1215273). Happy searching!

Now let's create a new collection for indexing documents in your 2-node cluster.
Please provide a name for your new collection: [gettingstarted] 
techproducts

4.关闭

sudo bin/solr delete -c techproducts
sudo bin/solr stop -all 
sudo rm -Rf example/cloud/

实际操作：

xc194@dku-dspace-app-dev-01:/$ cd /opt/solr-8.11.1/
xc194@dku-dspace-app-dev-01:/opt/solr-8.11.1$ sudo bin/solr delete -c techproducts
{
  "responseHeader":{
    "status":0,
    "QTime":283},
  "success":{
    "10.200.14.130:8983_solr":{"responseHeader":{
        "status":0,
        "QTime":37}},
    "10.200.14.130:7574_solr":{"responseHeader":{
        "status":0,
        "QTime":87}}}}


Deleted collection 'techproducts' using command:
