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

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! |
可以使用stop命令停止Solr，如下示例
| $ ./Solr stop |
| Sending stop command to Solr running on port 8983 ... waiting 5 seconds to |
| allow Jetty process 6035 to stop gracefully. |
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 |
| 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 |
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" |
| } |
