Solr配置与MongoDB的安装
Solr安装配置到目前已经非常简单，参考官方文档：http://lucene.apache.org/solr/quickstart.html，官方文档中用的是cloud这个样例(-e 指定)，最后，我采用的是techproducts，基本命令如下：
|
注意：如果unzip没有安装，请先安装：apt-get install unzip
root@xxx:xxx# ls solr-* solr-5.3.1.zip solr-5.3.1.zip root@xxx:xxx# unzip -q solr-5.3.1.zip root@xxx:xxx# cd solr-5.3.1/ -----------------------------安装好之后使用solr中自带的techproducts测试一下start-------------------------------------------- root@xxx:/home/software/solr-5.3.1# bin/solr start -e techproducts –noprompt Your current version of Java is too old to run this version of Solr We found version 1.7.0_79, using command '/usr/java/jdk1.7.0_79/bin/java' Please install latest version of Java 8 or set JAVA_HOME properly.
Debug information: JAVA_HOME: /usr/java/jdk1.7.0_79 Active Path: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/java/jdk1.7.0_79/bin:/usr/local/mongodb/bin
如果出现上面的提示语，请安装jdk1.7以上版本
安装好之后执行： root@xxx:/home/software/solr-5.3.1# bin/solr start -e techproducts -noprompt
这时候从浏览器访问： http://localhost:8983/solr/#/techproducts 的结果是：
|
|
上面的techproducts就是一个SolrCore ----------------------------------------------------------------安装好之后使用solr中自带的techproducts测试一下end--------------------------------------------------------------------------------- |
1、Solr的安装和启动停止
按照官方文档所说，如果你像用完后关闭solr,并清除这个样例底下的数据，那么请运行：
|
root@xxx:/home/software/solr-5.3.1# pwd /home/software/solr-5.3.1 root@xxx:/home/software/solr-5.3.1# bin/solr stop -all Sending stop command to Solr running on port 8983 ... waiting 5 seconds to allow Jetty process 1816 to stop gracefully.
root@xxx:/home/software/solr-5.3.1# rm -Rf example/techproducts/ |
注意：如果在停止所有之后执行：bin/solr start -all -noprompt 默认到，然后访问：http://localhost:8983/solr/ ，添加solrCore，它最后会到/home/software/solr-5.3.1/server/solr中去找。若没有，拷贝：/home/software/solr-5.3.1/example/techproducts/techproducts 到 /home/software/solr-5.3.1/server/solr 并将名称techproducts改成docdetection,例如：
并修改docdetection中的core.properties的内容为：
#Written by CorePropertiesLocator
#Fri Mar 31 18:36:50 UTC 2017
name=docdetection
config=solrconfig.xml
schema=schema.xml
dataDir=data
如果想创建多个，可以在docdetection同级目录下创建多个。比如：
core.properties的内容如下：
#Written by CorePropertiesLocator
#Fri Mar 31 18:36:50 UTC 2017
name=test
config=solrconfig.xml
schema=schema.xml
dataDir=data
进入/home/software/solr-5.3.1/server/solr-webapp/webapp/WEB-INF,修改web.xml中的
<env-entry>
<env-entry-name>solr/home</env-entry-name>
<env-entry-value>/home/software/solr-5.3.1/server/solr</env-entry-value>
<env-entry-type>java.lang.String</env-entry-type>
</env-entry>
接着刷新：http://localhost:8983/solr，最终的界面如下：
2、solr与MongoDB的整合
从Solr官方给的quickstart文档上来看，它可以搜索xml,json, csv等多种文档，但丝毫看不出这东西还能跟MongoDB整合，但是万能的人类总是能想办法把他们弄到一起，或许真的有*吧。
参考地址：http://www.cnblogs.com/sysuys/p/3403670.html
为了让solr和mongodb进行整合，需要mongo-connector，参考地址是：https://github.com/10gen-labs/mongo-connector/wiki/Getting-Started
关于mongo-connector的下载地址：https://github.com/mongodb-labs/mongo-connector
1） 、建立MongoDB的replica set(副本集)
安装python-pip 和 git
|
root@xxx:~# apt-get install python-pip root@xxx:~# apt-get install git |
|
Reading package lists... Done Building dependency tree Reading state information... Done The following extra packages will be installed: root@iZm5effj2tm01xy2qqmnlzZ:~# |
配置副本参考：http://blog.csdn.net/tototuzuoquan/article/details/76473441
2）、安装mongo-connector
2.1）、mongo-connector安装（推荐）
安装参考https://github.com/10gen-labs/mongo-connector，十分简单，一条命令：
|
可以在安装的时候，让mongo-connector作为一个后台进程，可以按照下面的步骤进行安装： 编辑config.json进行查看 root@xxx:/home/software/mongo-connector-master#pwd /home/software/mongo-connector-master
root@xxx:/home/software/mongo-connector-master# pip install mongo_connector[solr] 要注意的是，在后面同步solr的时候，要doc manager,所以，也需要对它进行安装，如果够仅仅是按照上面的方式安装，同步的时候会出现错误，在网上查了很久，最后直接在mongodb-connector中的README.rst找到了一个地址：https://github.com/mongodb-labs/solr-doc-manager (同理安装其它类型的doc-manger也类似)
如果没有安装：solr-doc-manager，请执行下面的命令：pip install solr-doc-manager
如果查找mongo-connector在哪儿，可以使用下面的方式： root@xxx:/etc/init.d# find / -name mongo-connector /home/software/mongo-connector-master/scripts/mongo-connector /usr/local/bin/mongo-connector
下面是安装elastic2-doc-manager 这个doc-manager root@xxx:/home/software/mongo-connector-master# pip install elastic2-doc-manager |
注意：如果提示没有python-pip，apt-get一下便好了。但是先别急着用，因为这个东西要读取solr的配置文件，所以Solr中的一些地方弄好了，再用这个就只是一条命令罢了。
注意：网上说通过pip安装，但是没有说卸载的，看下pip的说明：
|
root@xxx:/home/software/mongo-connector-master# pip --help
Usage: pip <command> [options] |
可以通过下面的方式进行卸载：
root@xxx:/home/software/mongo-connector-master# pip uninstall mongo-connector |
2.2）、第二种安装mongodb-connector的方式：
|
git clone https://github.com/10gen-labs/mongo-connector.git cd mongo-connector #安装前修改mongo_connector/constants.py的变量：设置DEFAULT_COMMIT_INTERVAL = 0 python setup.py install |
2.3）、第三种方式：https://github.com/mongodb-labs/mongo-connector上下载mongo-connector-master.zip （不推荐）
|
root@xxx:/home/software# unzip mongo-connector-master.zip root@xxx:/home/software# chmod +x setup.py root@xxx:/home/software# cd mongo-connector-master/ root@xxx:/home/software/mongo-connector-master# python setup.py install
running install_service creating /var/log/mongo-connector copying ./config.json -> /etc/mongo-connector.json copying ./scripts/mongo-connector -> /etc/init.d
root@xxx:/home/software/mongo-connector-master# chmod +x /etc/init.d/mongo-connector 执行下面的命令确保系统的启动配置被更新了： root@xxx:/home/software/mongo-connector-master# update-rc.d mongo-connector defaults update-rc.d: warning: default start runlevel arguments (2 3 4 5) do not match mongo-connector Default-Start values (3 4 5) Adding system startup for /etc/init.d/mongo-connector ... /etc/rc0.d/K20mongo-connector -> ../init.d/mongo-connector /etc/rc1.d/K20mongo-connector -> ../init.d/mongo-connector /etc/rc6.d/K20mongo-connector -> ../init.d/mongo-connector /etc/rc2.d/S20mongo-connector -> ../init.d/mongo-connector /etc/rc3.d/S20mongo-connector -> ../init.d/mongo-connector /etc/rc4.d/S20mongo-connector -> ../init.d/mongo-connector /etc/rc5.d/S20mongo-connector -> ../init.d/mongo-connector root@iZm5effj2tm01xy2qqmnlzZ:/home/software/mongo-connector-master#
如果想移除后台运行的可以执行下面的操作： python setup.py uninstall_service
通过这个命令可以移除/etc/init.d/mongo-connector 和 /etc/mongo-connector.json |
3）Solr一端的配置：
查找schema.xml,并修改这个文件
|
root@xxx:/home/software/solr-5.3.1# find ./ -name "schema.xml" ./example/example-DIH/solr/rss/conf/schema.xml ./example/example-DIH/solr/tika/conf/schema.xml ./example/example-DIH/solr/solr/conf/schema.xml ./example/example-DIH/solr/mail/conf/schema.xml ./example/example-DIH/solr/db/conf/schema.xml ./example/techproducts/solr/techproducts/conf/schema.xml ./server/solr/configsets/sample_techproducts_configs/conf/schema.xml ./server/solr/configsets/basic_configs/conf/schema.xml root@iZm5effj2tm01xy2qqmnlzZ:/home/software/solr-5.3.1# |
打开
vi ./server/solr/configsets/sample_techproducts_configs/conf/schema.xml |
将(linux上的查找方式是： Esc --à :/<uniqueKey>)
<uniqueKey>id</uniqueKey> |
改成带有下划线的id：
再添加（Linux上到达最第行的命令： Esc --à Shift + g）：
|
<field name="_id" type="string" indexed="true" stored="true" /> <field name="_ts" type="long" indexed="true" stored="true" /> <field name="ns" type="string" indexed="true" stored="true"/> |
添加后的效果如下：
注释掉原来的（命令是： Esc --à :/name="id"）
<!--
<field name="id"type="string" indexed="true" stored="true"required="true" multiValued="false" />
-->
截图如下：
不然往Solr中添加一个json，或者xml都要求有这个字段id,因为required=”true”
schema.xml的修改就是这些
修改solrconfig.xml
打开：
vi ./server/solr/configsets/sample_techproducts_configs/conf/solrconfig.xml |
将（关于下面的class如果配置错了，也将出不来solr和mongodb的数据同步,参考官网：https://github.com/mongodb-labs/mongo-connector/wiki/Usage%20with%20Solr#make-sure-the-lukerequesthandler-is-enabled）
<requestHandler name="/admin/luke" class="org.apache.solr.handler.admin.LukeRequestHandler" /> |
解注释，如果没有，就添加一行，这个东西要被mongo-connector用到，mongo-connector会请求获取上面的schema.xml，正是这个Handler来处理这个请求，所以说这个很重要。
最后：
最后，我们按照之前说的关闭Solr，清除example/techproducts目录，重新再次启动Solr，重启techproducts样例会产生一些错误，那是因为修改了schema.xml，里面uniqueKey变成了_id，而不是id，所以会产生这些错误，但这些都可以忽略，不产生错误就说明有问题。之后你会发现，那两个配置文件被复制成了exmaple/techproducts这个样例的配置文件，就像上文说的。
|
root@xxx:/home/software/solr-5.3.1# cd /home/software/solr-5.3.1 root@xxx:/home/software/solr-5.3.1# bin/solr stop -all Sending stop command to Solr running on port 8983 ... waiting 5 seconds to allow Jetty process 1816 to stop gracefully.
root@xxx:/home/software/solr-5.3.1# root@xxx:/home/software/solr-5.3.1# bin/solr start -e techproducts -noprompt |
4)使用mongo-connector连接Solr与MongoDB.
在目前情况下，请运行（其中：mongo-connector 的参考地址是：http://blog.csdn.net/hyman_yx/article/details/51684218）：
|
mongo-connector -m localhost:27017 --auto-commit-interval=0 -t http://localhost:8983/solr/techproducts -d solr_doc_manager & mongo-connector -m localhost:27017 --auto-commit-interval=0 -t http://localhost:8983/solr/docdetection -d solr_doc_manager & 注意： 若有时候发现重新创建索引的时候不给力，需要执行下面的命令（同时要删除索引，重新创建）： root@iZm5effj2tm01xy2qqmnlzZ:/home/software/solr-5.3.1# rm -rf mongo-connector.log root@iZm5effj2tm01xy2qqmnlzZ:/home/software/solr-5.3.1/server/solr/docdetection/data# pwd |
执行完成之后的效果如下：
查看mongo-connector进去的内容
经过以上步骤配置之后，终于可以看到（至此，配置成功）：
在MongoDB中的内容为：
如果有时候你发现你的solr没有自动同步数据，那是因为solr默认配置中，默认把自动同步给关闭了，这时候需要对solrconfig.xml自动同步的开关进行设置，可以以下操作
进入solr的目录（注意：我的solr是放在/home/software/solr-5.3.1）中的：
cd /home/software/solr-5.3.1
查找solrconfig.xml
find ./ -name solrconfig.xml,结果如下：
|
./example/files/conf/solrconfig.xml ./example/example-DIH/solr/rss/conf/solrconfig.xml ./example/example-DIH/solr/tika/conf/solrconfig.xml ./example/example-DIH/solr/solr/conf/solrconfig.xml ./example/example-DIH/solr/mail/conf/solrconfig.xml ./example/example-DIH/solr/db/conf/solrconfig.xml ./example/techproducts/solr/techproducts/conf/solrconfig.xml ./server/solr/configsets/sample_techproducts_configs/conf/solrconfig.xml ./server/solr/configsets/basic_configs/conf/solrconfig.xml ./server/solr/configsets/data_driven_schema_configs/conf/solrconfig.xml |
修改上面红色标注出来的文件中的如下内容进行修改：
|
<autoCommit> <maxTime>${solr.autoCommit.maxTime:15000}</maxTime> <openSearcher>false</openSearcher> </autoCommit>
<!-- softAutoCommit is like autoCommit except it causes a 'soft' commit which only ensures that changes are visible but does not ensure that data is synced to disk.

要注意的是，如果想在solr中再次添加mongodb中中的key作为索引元素，需要编辑solrCore中的schema.xml中的内容。下面的一个例子是：
<?xml version="1.0" encoding="UTF-8" ?>
<schema name="example" version="1.5">
<types>
<fieldType name="string" class="solr.StrField" sortMissingLast="true" />
<fieldType name="boolean" class="solr.BoolField" sortMissingLast="true"/>
<fieldType name="int" class="solr.TrieIntField" precisionStep="0" positionIncrementGap="0"/>
<fieldType name="float" class="solr.TrieFloatField" precisionStep="0" positionIncrementGap="0"/>
<fieldType name="long" class="solr.TrieLongField" precisionStep="0" positionIncrementGap="0"/>
<fieldType name="double" class="solr.TrieDoubleField" precisionStep="0" positionIncrementGap="0"/>
<fieldType name="date" class="solr.TrieDateField" precisionStep="0" positionIncrementGap="0"/>
<!--

</fields>
<uniqueKey>_id</uniqueKey>

</schema>
回到执行mongodb-connector命令的所在位置：
mongo-connector -m localhost:27017 --auto-commit-interval=0 -t http://localhost:8983/solr/docdetection -d solr_doc_manager &
找到：oplog.timestamp，然后删除。同样，也可以删除mongo-connector.log这个文件
进入索引的存放目录：
cd /home/software/solr-5.3.1/server/solr/docdetection/data
删除生成的所有的索引信息rm -rf * (注意目录在：cd /home/software/solr-5.3.1/server/solr/docdetection/data)
然后再执行：
重启solr，命令在博文的上面：
mongo-connector -m localhost:27017 --auto-commit-interval=0 -t http://localhost:8983/solr/docdetection -d solr_doc_manager &
