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

    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

    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

    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"
    }
