启动Solr

安装Solr后，进入到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

在 Windows 系统中使用以下命令 -

此命令在后台启动Solr，通过显示以下消息监听端口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

如果使用start命令启动Solr，那么Solr将在后台启动。然而可以使用-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start命令的-p选项指定一个启动端口，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 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，显示消息如下所示。

Sending stop command to Solr running on port 8983 ... waiting 5 seconds to 
allow Jetty process 6035 to stop gracefully.

重新启动Solr

Solr的 restart 命令会停止Solr 5秒钟，然后再次启动。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

Solr的help命令可用于查看Solr提示及其选项的用法。

[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 -help

Solr ─ status命令

Solr的 status 命令可用于在计算机上搜索和找出运行的Solr实例。它可以提供有关Solr实例的信息，例如它的版本，内存使用情况等。

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，显示上述Solr的status命令结果如下 -

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"
}
