利用SOLR搭建企业搜索平台 之 MultiCore

1》找到solr下载包中的example文件夹，在它的下面有个multicore文件夹，将这个文件夹下面的所有东西

copy到 c:\solr-tomcat\solr下面。

注意：有一个 solr.xml（这只是默认文件，当然也可以指定别的文件），如：

 

<?xml version="1.0" encoding="UTF-8" ?>
<solr persistent="false">
<cores adminPath="/admin/cores">
<core name="core0" instanceDir="core0" />
<core name="core1" instanceDir="core1" />
</cores>
</solr>

 

 

这个文件是告诉solr应该加载哪些core，cores里有 core0,core1。core0（可以类比以前的solr.home）/conf

目录下有schema.xml与solrconfig.xml，可以把实际应用的复制过来。现示例就用官方的了。

2》启动tomcat，访问应用，就可以看到有 Admin core0 和 Admin core1

3》采用上面的默认solr.xml，索引文件将存放在同一个目录下面，在这里将存放在C:\solr-tomcat\solr\data，

如果你想更改目录，或者两个应用存放在不同的目录，请参见下面的xml。

 

<core name="core0" instanceDir="core0">
<property name="dataDir" value="/data/core0" />
</core>

 

给core添加子元素 property，property的两个属性就不说了，一看就能明白！

solr.core.name -- The core's name as defined in solr.xml

solr.core.instanceDir -- The core's instance directory (i.e. the directory under which that core's conf/

and data/ directory are located)

solr.core.dataDir -- The core's data directory (i.e. the directory under which that core's index directory

are located)

solr.core.configName -- The name of the core's config file (solrconfig.xml by default)

solr.core.schemaName -- The name of the core's schema file (schema.xml by default)

 

4》solr.xml具体含义：

1）solr

The <solr> tag accepts two attributes:

persistent - By default, should runtime core manipulation be saved in solr.xml so that it is available

after a restart.

sharedLib - Path to a directory containing .jar files that are added to the classpath of every core. The

path is relative to solr.home (where solr.xml sits)

2）cores

The <cores> tag accepts two attribute:

adminPath - Relative path to access the CoreAdminHandler for dynamic core manipulation. For

example, adminPath="/admin/cores" configures access via http://localhost:8983/solr/admin/cores. If

this attribute is not specified, dynamic manipulation is unavailable.

 

3）core

The <core> tag accepts two attributes:

name - The registered core name. This will be how the core is accessed.

instanceDir - The solr.home directory for a given core.

dataDir - The data directory for a given core. The default is <instanceDir>/data . It can take an

absolute path or a relative path w.r.t instanceDir . Solr1.4

4）property

The <property> tag accepts two attributes:

name - The name of the property

value - The value of the property
