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，通过显示以下消息来侦听端口 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

如果您使用start命令启动Solr，那么 Solr 将在后台启动。相反，您可以使用–f 选项在前台启动 Solr 。

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

5823 INFO  (coreLoadExecutor-6-thread-2) [   ] o.a.s.c.SolrResourceLoader

在另一个端口上启动 Solr

使用启动命令的-p选项，我们可以在另一个端口启动Solr，如以下代码块所示。

[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 的重启命令使 Solr 停止 5 秒，然后再次启动。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 ─ 帮助命令

Solr的help命令可以用来查看Solr提示符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 ─ 状态命令

Solr 的此状态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"
}
