1 在ubuntu11.04下安装tomcat 6
sudo apt-get install tomcat6 tomcat6-admin tomcat6-common tomcat6-user tomcat6-docs tomcat6-examples
sudo apt-get install libmysql-java

2.下载apache-solr-1.4.1.zip并解压
cd ~/
wget -c http://ftp.riken.jp/net/apache//lucene/solr/1.4.1/apache-solr-1.4.1.zip
unzip apache-solr-1.4.1.zip
sudo cp ~/apache-solr-1.4.1/dist/apache-solr-1.4.1.war /var/lib/tomcat6/webapps/solr.war
sudo cp -R ~/apache-solr-1.4.1/example/solr/ /var/lib/tomcat6/solr/

3. 在tomcat6里面设置solr环境
sudo vim /etc/tomcat6/Catalina/localhost/solr.xml

加入如下内容

<Context docBase=”/var/lib/tomcat6/webapps/solr.war” debug=”0″ privileged=”true” allowLinking=”true” crossContext=”true”> <Environment name=”solr/home” type=”java.lang.String” value=”/var/lib/tomcat6/solr” override=”true” /> </Context>

4. 设置solrconfig.xml环境，并建立data文件夹
mkdir /var/lib/tomcat6/solr/data

设置tomcat6访问data的权限

chown -R tomcat6:tomcat6 /var/lib/tomcat6/solr/data/

通过solr/conf/solrconfig.xml来设置data路径
<– Used to specify an alternate directory to hold all index data other than the default ./data under the Solr home. If replication is in use, this should match the replication configuration. –>
/var/lib/tomcat6/solr/data

5. 重启tomcat后进入solr
sudo service tomcat6 restart
http://localhost:8080/solr/admin

Done
