Apache Solr 基本命令
安装 Solr 后，浏览到 bin Solr 主目录中的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
如果你开始 Solr 使用 start 命令，然后 Solr 将在后台启动。相反，你可以使用 -f 选项 .
[Hadoop@localhost bin]$ ./Solr start –f 5823 INFO (coreLoadExecutor-6-thread-2) [ ] o.a.s.c.SolrResourceLoader Adding 'file:/home/Hadoop/Solr/contrib/extraction/lib/xmlbeans-2.6.0.jar' to classloader 5823 INFO (coreLoadExecutor-6-thread-2) [ ] o.a.s.c.SolrResourceLoader Adding 'file:/home/Hadoop/Solr/dist/Solr-cell-6.2.0.jar' to classloader 5823 INFO (coreLoadExecutor-6-thread-2) [ ] o.a.s.c.SolrResourceLoader Adding 'file:/home/Hadoop/Solr/contrib/clustering/lib/carrot2-guava-18.0.jar' to classloader 5823 INFO (coreLoadExecutor-6-thread-2) [ ] o.a.s.c.SolrResourceLoader Adding 'file:/home/Hadoop/Solr/contrib/clustering/lib/attributes-binder1.3.1.jar' to classloader 5823 INFO (coreLoadExecutor-6-thread-2) [ ] o.a.s.c.SolrResourceLoader Adding 'file:/home/Hadoop/Solr/contrib/clustering/lib/simple-xml-2.7.1.jar' to classloader …………………………………………………………………………………………………………………………………………………………………………………………………………… …………………………………………………………………………………………………………………………………………………………………………………………………. 12901 INFO (coreLoadExecutor-6-thread-1) [ x:Solr_sample] o.a.s.u.UpdateLog Took 24.0ms to seed version buckets with highest version 1546058939881226240 12902 INFO (coreLoadExecutor-6-thread-1) [ x:Solr_sample] o.a.s.c.CoreContainer registering core: Solr_sample 12904 INFO (coreLoadExecutor-6-thread-2) [ x:my_core] o.a.s.u.UpdateLog Took 16.0ms to seed version buckets with highest version 1546058939894857728 12904 INFO (coreLoadExecutor-6-thread-2) [ x:my_core] o.a.s.c.CoreContainer registering core: my_core
在另一个端口上启动 Solr
Using -p 选项 of the start 命令，我们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 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
你可以使用 stop command.
$ ./Solr stop
此命令会停止 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
The restart Solr 命令停止 Solr 5 秒，然后再次启动它。你可以使用以下命令重新启动 Solr：
./Solr restart
该命令重启 Solr，显示如下信息：
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
The help Solr 命令可用于检查 Solr 提示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 ─ status 命令
This status Solr 命令可用于搜索和查找计算机上正在运行的 Solr 实例。它可以为你提供有关 Solr 实例的信息，例如其版本、内存使用情况等。
你可以使用 status 命令检查 Solr 实例的状态，如下所示：
[Hadoop@localhost bin]$ ./Solr status
上面的命令在执行时会显示 Solr 的状态如下：
Found 1 Solr nodes:
Solr process 6906 running on port 8983 {
"Solr_home":"/home/Hadoop/Solr/server/Solr",
