ElasticSearch之cat shards API

命令样例如下：

curl -X GET "https://localhost:9200/_cat/shards?v=true&pretty" --cacert $ES_HOME/config/certs/http_ca.crt -u "elastic:ohCxPH=QBE+s5=*lo7F9"

执行结果输出如下：

index       shard prirep state   docs  store dataset ip        node
.security-7 0     p      STARTED    2 12.6kb  12.6kb 127.0.0.1 jackie-ubuntu
