Solr基本命令
啓動Solr
安裝Solr後，進入到Solr主目錄中的bin文件夾，並使用以下命令啓動Solr。
[Hadoop@localhost ~]$ cd
[Hadoop@localhost ~]$ cd Solr/
[Hadoop@localhost Solr]$ cd bin/
[Hadoop@localhost bin]$ ./Solr start在 Windows 系統中使用以下命令 -
此命令在後臺啓動Solr，通過顯示以下消息監聽端口8983。
Waiting up to 30 seconds to see Solr running on port 8983 [\]
Started Solr server on port 8983 (pid = 6035). Happy searching!在前臺啓動Solr
如果使用start命令啓動Solr，那麼Solr將在後臺啓動。然而可以使用-f選項在前臺啓動Solr。
[Hadoop@localhost bin]$ ./Solr start –f

使用start命令的-p選項指定一個啓動端口，可以在另一個端口啓動Solr，如下面的代碼塊所示。
[Hadoop@localhost bin]$ ./Solr start -p 8081
Waiting up to 30 seconds to see Solr running on port 8081 [-]
Started Solr server on port 8081 (pid = 10137). Happy searching!停止Solr
可以使用stop命令停止Solr，如下示例 -
$ ./Solr stop此命令停止Solr，顯示消息如下所示。
Sending stop command to Solr running on port 8983 ... waiting 5 seconds to
allow Jetty process 6035 to stop gracefully.重新啓動Solr
Solr的 restart 命令會停止Solr 5秒鐘，然後再次啓動。可以使用以下命令重新啓動Solr -
./Solr restart此命令重新啓動Solr，顯示以下消息 -
Sending stop command to Solr running on port 8983 ... waiting 5 seconds to
allow Jetty process 6671 to stop gracefully.
Waiting up to 30 seconds to see Solr running on port 8983 [|] [/]
Started Solr server on port 8983 (pid = 6906). Happy searching!Solr ─ help 命令
Solr的help命令可用於查看Solr提示及其選項的用法。
[Hadoop@localhost bin]$ ./Solr -help
Usage: Solr COMMAND OPTIONS
where COMMAND is one of: start, stop, restart, status, healthcheck,
create, create_core, create_collection, delete, version, zk
Standalone server example (start Solr running in the background on port 8984):
./Solr start -p 8984
SolrCloud example (start Solr running in SolrCloud mode using localhost:2181
to connect to Zookeeper, with 1g max heap size and remote Java debug options enabled):
./Solr start -c -m 1g -z localhost:2181 -a "-Xdebug -
Xrunjdwp:transport = dt_socket,server = y,suspend = n,address = 1044"
Pass -help after any COMMAND to see command-specific usage information,
such as: ./Solr start -help or ./Solr stop -helpSolr ─ status命令
Solr的 status 命令可用於在計算機上搜索和找出運行的Solr實例。它可以提供有關Solr實例的信息，例如它的版本，內存使用情況等。
可以使用status命令檢查Solr實例的狀態，如下所示：
[Hadoop@localhost bin]$ ./Solr status執行時，顯示上述Solr的status命令結果如下 -
