  Apache Solr - 基本命令

  • 启动 Solr

    安装 Solr 后，浏览到binSolr 主目录中的文件夹并使用以下命令启动 Solr。 
    
[Hadoop@localhost ~]$ cd   
[Hadoop@localhost ~]$ cd Solr/ 
[Hadoop@localhost Solr]$ cd bin/ 
[Hadoop@localhost bin]$ ./Solr start
    此命令在后台启动 Solr，通过显示以下消息侦听端口 8983。 
    
Waiting up to 30 seconds to see Solr running on port 8983 [\]   
Started Solr server on port 8983 (pid = 6035). Happy searching!

    在前台启动 Solr

    如果你开始Solr使用start命令，然后 Solr 将在后台启动。相反，您可以使用–f option. 
    
[Hadoop@localhost bin]$ ./Solr start –f  
5823 INFO  (coreLoadExecutor-6-thread-2) [   ] o.a.s.c.SolrResourceLoader 
Adding 'file:/home/Hadoop/Solr/contrib/extraction/lib/xmlbeans-2.6.0.jar' to 
classloader 
5823 INFO  (coreLoadExecutor-6-thread-2) [   ] o.a.s.c.SolrResourceLoader

    在另一个端口上启动 Solr

    使用–p optionstart命令，我们可以在另一个端口启动 Solr，如下面的代码块所示。 
    
[Hadoop@localhost bin]$ ./Solr start -p 8984  
Waiting up to 30 seconds to see Solr running on port 8984 [-]   
Started Solr server on port 8984 (pid = 10137). Happy searching!

  • 停止 Solr

    您可以使用stop命令。 
    
$ ./Solr stop
    此命令会停止 Solr，并显示如下所示的消息。 
    
Sending stop command to Solr running on port 8983 ... waiting 5 seconds to 
allow Jetty process 6035 to stop gracefully.

  • 重启 Solr

    这restartSolr 命令停止 Solr 5 秒，然后再次启动它。您可以使用以下命令重新启动 Solr - 
    
./Solr restart
    此命令重新启动 Solr，显示以下消息 - 
    
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

    这helpSolr 命令可用于检查 Solr 提示及其选项的使用情况。 
    
[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 -help

  • Solr ─ status 命令

    这个statusSolr 命令可用于搜索和查找计算机上正在运行的 Solr 实例。它可以为您提供有关 Solr 实例的信息，例如其版本、内存使用情况等。
    您可以使用 status 命令检查 Solr 实例的状态，如下所示 - 
    
[Hadoop@localhost bin]$ ./Solr status
    执行时，上述命令显示 Solr 的状态如下 - 
    
Found 1 Solr nodes:   
Solr process 6906 running on port 8983 {   
   "Solr_home":"/home/Hadoop/Solr/server/Solr",   
   "version":"6.2.0 764d0f19151dbff6f5fcd9fc4b2682cf934590c5 - 
   mike - 2016-08-20 05:41:37",   
   "startTime":"2016-09-20T06:00:02.877Z",   
   "uptime":"0 days, 0 hours, 5 minutes, 14 seconds",   
   "memory":"30.6 MB (%6.2) of 490.7 MB"
}

  • Solr 管理员

    启动 Apache Solr 后，可以访问Solr web interface通过使用以下 URL。 
    
Localhost:8983/Solr/
    Solr Admin 的界面如下所示 -
