Solr基本命令
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

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 -

Solr process 6906 running on port 8983 {
