Apache Solr 简明教程
Apache Solr - Basic Commands
Starting Solr
在安装 Solr 之后，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，监听端口 8983，并显示以下消息。

如果您使用 start 命令启动 Solr ，则 Solr 将在后台启动。取而代之的是，您可以使用 –f option 在前台启动 Solr。
[Hadoop@localhost bin]$ ./Solr start –f

您可以使用 stop 命令停止 Solr。
$ ./Solr stop如下所示命令会停止 Solr，并显示一条消息：

allow Jetty process 6035 to stop gracefully.Restarting Solr
Solr 的 restart 命令会让 Solr 停止运行 5 秒，然后自动再次启动。你可以使用以下命令重启 Solr：
./Solr restart如下所示命令会重启 Solr，并显示以下消息：

可以通过 Solr 的 help 命令检查 Solr 提示符及其选项被使用的状况。
[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 -helpSolr ─ status Command
可以通过 Solr 的 status 命令搜索和找出你的计算机上正在运行的 Solr 实例。该命令可以提供 Solr 实例的相关信息，例如它的版本、内存使用情况等。
你可以使用状态命令，如下所示，检查 Solr 实例的状态：
[Hadoop@localhost bin]$ ./Solr status在执行该命令后，它会如下所示显示 Solr 的状态：
