Apache Solr - 基本命令

启动 Solr

安装 Solr 后，浏览到 Solr 主目录中的 **bin** 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，并在端口 8983 上监听，并显示以下消息。

Waiting up to 30 seconds to see Solr running on port 8983 [\]   
Started Solr server on port 8983 (pid = 6035). Happy searching!

在前景启动 Solr

如果使用 **start** 命令启动 **Solr**，则 Solr 将在后台启动。相反，您可以使用 **–f 选项** 在前景启动 Solr。

[Hadoop@localhost bin]$ ./Solr start –f

在其他端口上启动 Solr

使用 **start** 命令的 **–p 选项**，我们可以在其他端口上启动 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** 命令停止 Solr。

$ ./Solr stop

此命令停止 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

Solr 的 **restart** 命令会停止 Solr 5 秒钟，然后再次启动它。您可以使用以下命令重启 Solr -

./Solr restart

此命令重启 Solr，并显示以下消息 -

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

Solr 的 **help** 命令可用于检查 Solr 提示及其选项的使用方法。

[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 -help

Solr ─ status 命令

Solr 的 **status** 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。

您可以使用以下 status 命令检查 Solr 实例的状态 -

[Hadoop@localhost bin]$ ./Solr status

执行上述命令后，Solr 的状态将显示如下 -

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"
}
