Solr系統(tǒng)信息

Solr 版本信息

version 命令只是返回當(dāng)前安裝的 Solr 版本，并且立即存在。

$ bin/solr version
X.Y.0

Solr 狀態(tài)信息

status 命令顯示在本地系統(tǒng)上運(yùn)行的任何 Solr 節(jié)點(diǎn)的基本 JSON 格式的信息。

status 命令使用 SOLR_PID_DIR 環(huán)境變量來(lái)定位 Solr 進(jìn)程 ID 文件以查找正在運(yùn)行的 Solr 實(shí)例，默認(rèn)情況下是 bin 目錄。

bin/solr status

輸出將包含群集中每個(gè)節(jié)點(diǎn)的狀態(tài)，如下例所示：

找到2個(gè) Solr 節(jié)點(diǎn):

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 模式下運(yùn)行時(shí)，healthcheck 命令將為集合生成 JSON 格式的運(yùn)行狀況報(bào)告。運(yùn)行狀況報(bào)告提供有關(guān)集合中所有碎片的每個(gè)副本狀態(tài)的信息，包括已提交文檔的數(shù)量及其當(dāng)前狀態(tài)。

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

健康檢查參數(shù)

-c <collection>

（要求）運(yùn)行健康檢查的集合的名稱。例如：

bin/solr healthcheck -c gettingstarted

-z <zkhost>

ZooKeeper 連接字符串，默認(rèn)為localhost:9983。如果您在8983以外的端口上運(yùn)行 Solr，則必須指定 ZooKeeper 連接字符串。默認(rèn)情況下，這將是 Solr 端口 + 1000。例如：

bin/solr healthcheck -z localhost:2181

以下是使用非標(biāo)準(zhǔn) ZooKeeper 連接字符串運(yùn)行的 healthcheck 請(qǐng)求和響應(yīng)示例，其中包含2個(gè)節(jié)點(diǎn)：

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