Solr architecture diagram
Start the installation:
Go to the website http://lucene.apache.org/solr/downloads.html to download the corresponding version, such as version 6.2.1, and download it to the / usr/local directory
# cd / usr/local
# tar-zxf solr-6.2.1.tgz
# cd / usr/local/solr-6.2.1
Modify the port number to 8983:
Cat / usr/local/solr-6.2.1/server/solr/solr.xml
.
${host:192.168.18.68}
${jetty.port:8983}
${hostContext:solr}
.
Start the service
# / usr/local/solr-6.2.1/bin/solr start
Waiting up to 30 seconds to see Solr running on port 8983 [/]
Started Solr server on port 8983 (pid=113190). Happy searching!
Verification service
# / usr/local/solr-6.2.1/bin/solr status
Found 1 Solr nodes:
Solr process 113190 running on port 8983

There is no core by default and needs to be created.
Core is an index library of solr, which can be understood as a database. Core can create multiple databases as needed.
An error will be reported when creating a core for the first time, for example, an error will be reported when creating a core,Add Core named test
Unable to create core [new_core] Caused by: Can't find resource 'solrconfig.xml' in classpath..
Solution:
You need to create a database directory called test in the / usr/local/solr-6.2.1/server/solr directory, and then copy the conf directory in basic_configs to the database directory:
[root@alpha-solr-68 local] # mkdir-p / usr/local/solr-6.2.1/server/solr/test
[root@alpha-solr-68 local] # cp-r / usr/local/solr-6.2.1/server/solr/configsets/basic_configs/conf / usr/local/solr-6.2.1/server/solr/test
You need to restart the service:
[root@alpha-solr-68 local] # / usr/local/solr-6.2.1/bin/solr stop
Sending stop command to Solr running on port 8983... Waiting 5 seconds to allow Jetty process 113190 to stop gracefully.
[root@alpha-solr-68 local] #
[root@alpha-solr-68 local] #
[root@alpha-solr-68 local] # / usr/local/solr-6.2.1/bin/solr start
Waiting up to 30 seconds to see Solr running on port 8983 [/]
Started Solr server on port 8983 (pid=114488). Happy searching!
