Solr系统信息

Solr 版本信息

version 命令只是返回当前安装的 Solr 版本，并且立即存在。

$ bin/solr version
X.Y.0

Solr 状态信息

status 命令显示在本地系统上运行的任何 Solr 节点的基本 JSON 格式的信息。

status 命令使用 SOLR_PID_DIR 环境变量来定位 Solr 进程 ID 文件以查找正在运行的 Solr 实例，默认情况下是 bin 目录。

bin/solr status

输出将包含群集中每个节点的状态，如下例所示：

找到2个 Solr 节点:

Solr process 39920 running on port 7574
{
  "solr_home":"/Applications/Solr/example/cloud/node2/solr/",
  "version":"X.Y.0",
  "startTime":"2015-02-10T17:19:54.739Z",
  "uptime":"1 days, 23 hours, 55 minutes, 48 seconds",
  "memory":"77.2 MB (%15.7) of 490.7 MB",
  "cloud":{
    "ZooKeeper":"localhost:9865",
    "liveNodes":"2",
    "collections":"2"}}

Solr process 39827 running on port 8865
{
  "solr_home":"/Applications/Solr/example/cloud/node1/solr/",
  "version":"X.Y.0",
  "startTime":"2015-02-10T17:19:49.057Z",
  "uptime":"1 days, 23 hours, 55 minutes, 54 seconds",
  "memory":"94.2 MB (%19.2) of 490.7 MB",
  "cloud":{
    "ZooKeeper":"localhost:9865",
    "liveNodes":"2",
    "collections":"2"}}

Healthcheck

在 SolrCloud 模式下运行时，healthcheck 命令将为集合生成 JSON 格式的运行状况报告。运行状况报告提供有关集合中所有碎片的每个副本状态的信息，包括已提交文档的数量及其当前状态。

bin/solr healthcheck [options]
bin/solr healthcheck -help

健康检查参数

-c <collection>

（要求）运行健康检查的集合的名称。例如：

bin/solr healthcheck -c gettingstarted

-z <zkhost>

ZooKeeper 连接字符串，默认为localhost:9983。如果您在8983以外的端口上运行 Solr，则必须指定 ZooKeeper 连接字符串。默认情况下，这将是 Solr 端口 + 1000。例如：

bin/solr healthcheck -z localhost:2181

以下是使用非标准 ZooKeeper 连接字符串运行的 healthcheck 请求和响应示例，其中包含2个节点：

$ bin/solr healthcheck -c gettingstarted -z localhost:9865
