Lu Chunli's work notes are not as good as bad notes.

1. View help

At the bottom of Admin UI, you can connect to the appropriate website to view help information about Solr.

2 、 Dashboard

The default page of Admin UI, which mainly includes:

Instance information (such as solr service startup time)

Version information (solr and lucene version information)

JVM configuration parameters such as

-DSTOP.KEY=solrrocks

-DSTOP.PORT=7983

-Djetty.home=/lucl/solr-5.3.0/server

-Djetty.port=8983

-Dsolr.install.dir=/lucl/solr-5.3.0

And host system information (such as memory, swap space, file descriptor and JVM memory usage).

3 、 Logging

Log files are created in units of Core (index library), and log levels can be set.

Note: the log level of Solr is quite fine, and you can configure a class separately.

4 、 Core Admin

The Core (index library) used to manage Solr, and the CoreAdminHandler class encapsulates its functional implementation.

5 、 Java Properties

The Solr operation is the configuration parameter, and the default parameter can be overridden by-D parameter name = parameter value.

6 、 Thread Dump

The Thread Dump screen lets you inspect the currently active threads on your server.

7 、 Manage Core

Always prompts an error when executing Add Core through Admin UI:

Error CREATEing SolrCore 'my_core': Unable to create core [new_core] Caused by: Can't find resource' solrconfig.xml' in classpath or'/ lucl/solr-5.3.0/server/solr/my_core/conf'

So create it through command script execution:

[hadoop@nnode solr-5.3.0] $bin/solr create-c test_coreSetup new core instance directory:/lucl/solr-5.3.0/server/solr/test_coreCreating new core' test_core' using command: http://localhost:8983/solr/admin/cores?action=CREATE&name=test_core&instanceDir=test_core{ "responseHeader": {"status": 0, "QTime": 3876}, "core": "test_core"} [hadoop@nnode solr-5.3.0] $

Note: if the creation fails, you can delete it using the name of the bin/solr delete-c index library.
