Solr5.0快速入門

一，安裝環境 
硬件：虛擬機 
操作系統：Centos 6.4 64位 
IP：10.51.121.10 
主機名：datanode-4 
安裝用戶：root 
安裝系統要求：需要先安裝JDK7或者以上版本，推薦JDK7U55或者以后版本。

二，安裝JDK7 
安裝JDK7U55或者以上版本。這里安裝JDK1.7.0_75。 
下載地址：http://www.oracle.com/technetwork/java/javase/downloads/index.html 
1，下載jdk-7u75-linux-x64.tar.gz，執行：#tar -zxvf jdk-7u75-linux-x64.tar.gz 
到/usr/lib目錄。解壓之后的目錄為：/usr/lib/jdk1.7.0_75

2，在/root/.bash_profile中添加如下配置：

export JAVA_HOME=/usr/lib/jdk1.7.0_75 export PATH=$JAVA_HOME/bin:$PATH

3，使環境變量生效#source ~/.bash_profile 
4，安裝驗證# java -version 
java version “1.7.0_75” 
Java(TM) SE Runtime Environment (build 1.7.0_75-b13) 
Java HotSpot(TM) 64-Bit Server VM (build 24.75-b04, mixed mode)

三，安裝Solr 
1，下載Solr5.0，下載URL：http://archive.apache.org/dist/lucene/solr/5.0.0/solr-5.0.0.tgz 
2，執行：#tar -zxvf solr-5.0.0.tgz 
到/root/nutch目錄。解壓之后的目錄為：/root/nutch/solr-5.0.0

四，啟動Solr服務 
1，進入solr的安裝目錄，/root/nutch/solr-5.0.0 
2，執行，#./bin/solr start -e cloud -noprompt 
Welcome to the SolrCloud example! 
Starting up 2 Solr nodes for your example SolrCloud cluster. 
… 
Started Solr server on port 8983 (pid=8404). Happy searching! 
… 
Started Solr server on port 7574 (pid=8549). Happy searching! 
… 
SolrCloud example running, please visit http://localhost:8983/solr

Solr在2個節點上運行，一個端口是8983，另一個端口是7574。並自動建立了名稱為gettingstarted的collection，此collection有2個shard，每個shard有replicas。 
3，在瀏覽器中輸入：http://10.51.121.10:8983/solr/ 

四，建立索引 
指定需要建立索引數據源，數據源可以是HTML, PDF, Microsoft Office 文件(比如 MS Word、Excel)，平面文件等。 
這里為solr安裝目錄下的docs文件夾中的文件建立索引。 
1，執行#bin/post -c gettingstarted docs/

#bin/post -c gettingstarted docs/ java -classpath /solr-5.0.0/dist/solr-core-5.0.0.jar -Dauto=yes -Dc=gettingstarted -Ddata=files -Drecursive=yes org.apache.solr.util.SimplePostTool docs/ SimplePostTool version 5.0.0 Posting files to [base] url http://localhost:8983/solr/gettingstarted/update... Entering auto mode. File endings considered are xml,json,csv,pdf,doc,docx,ppt,pptx,xls,xlsx,odt,odp,ods,ott,otp,ots,rtf,htm,html,txt,log Entering recursive mode, max depth=999, delay=0s Indexing directory docs (3 files, depth=0) POSTing file index.html (text/html) to [base]/extract POSTing file quickstart.html (text/html) to [base]/extract POSTing file SYSTEM_REQUIREMENTS.html (text/html) to [base]/extract Indexing directory docs/changes (1 files, depth=1) POSTing file Changes.html (text/html) to [base]/extract ... 3254 files indexed. COMMITting Solr index changes to http://localhost:8983/solr/gettingstarted/update... Time spent: 0:02:27.712

2，為xml文件建立索引

#bin/post -c gettingstarted example/exampledocs/*.xml

3，為JSON文件建立索引

#bin/post -c gettingstarted example/exampledocs/*.json

4，為CSV文件建立索引

#bin/post -c gettingstarted example/exampledocs/books.csv

五，搜索 
Solr可以通過REST 客戶端，cURL命令，wget命令等方式來訪問搜索。 
1，進入http://10.51.121.10:8983/solr，選擇gettingstarted_shard1_replica2，點擊Query Tab，在q輸入域中輸入”solr”，然后點擊”Execute Query”按鈕，這時可以查到內容為solr的文件。 

2，在Linux Shell中用cURL訪問，比如：

# curl "http://localhost:8983/solr/gettingstarted/select?wt=json&indent=true&q=foundation"

# curl "http://localhost:8983/solr/gettingstarted/select?wt=json&indent=true&q=foundation" { "responseHeader":{ "status":0, "QTime":26, "params":{ "indent":"true", "q":"foundation", "wt":"json"}}, "response":{"numFound":3105,"start":0,"maxScore":0.13157843,"docs":[ { "id":"UTF8TEST", "name":["Test with some UTF-8 encoded characters"], "manu":["Apache Software Foundation"], "cat":["software", "search"], ...... 

3，訪問http://10.51.121.10:8983/solr/gettingstarted/browse。 

六，常用命令 
1，solr命令有start, stop, restart, status, healthcheck, create, create_core, create_collection, delete。

# ./bin/solr

Usage: solr COMMAND OPTIONS
       where COMMAND is one of: start, stop, restart, status, healthcheck, create, create_core, create_collection, delete 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

2，healthcheck命令

[root@datanode-4 solr-5.0.0]# bin/solr healthcheck -c gettingstarted { "collection":"gettingstarted", "status":"healthy", "numDocs":3296, "numShards":2, "shards":[ { "shard":"shard1", "status":"healthy", "replicas":[ { "name":"core_node2", "url":"http://10.51.121.10:8983/solr/gettingstarted_shard1_replica2/", "numDocs":1633, "status":"active", "uptime":"0 days, 0 hours, 42 minutes, 6 seconds", "memory":"36.9 MB (%7.5) of 490.7 MB"}, { "name":"core_node4", "url":"http://10.51.121.10:7574/solr/gettingstarted_shard1_replica1/", "numDocs":1633, "status":"active", "uptime":"0 days, 0 hours, 41 minutes, 44 seconds", "memory":"83.2 MB (%17) of 490.7 MB", "leader":true}]}, { "shard":"shard2", "status":"healthy", "replicas":[ { "name":"core_node1", "url":"http://10.51.121.10:8983/solr/gettingstarted_shard2_replica2/", "numDocs":1663, "status":"active", "uptime":"0 days, 0 hours, 42 minutes, 6 seconds", "memory":"37.1 MB (%7.6) of 490.7 MB"}, { "name":"core_node3", "url":"http://10.51.121.10:7574/solr/gettingstarted_shard2_replica1/", "numDocs":1663, "status":"active", "uptime":"0 days, 0 hours, 41 minutes, 44 seconds", "memory":"83.3 MB (%17) of 490.7 MB", "leader":true}]}]}
