Solr的服务器没有启动

Question

我Solr的服务器没有启动tomcat7使用创建AWS bitnami tomcat的叠加
下面是错误：

SEVERE: Error deploying configuration descriptor /opt/bitnami/apache-tomcat/conf/Catalina/localhost/solr.xml 
java.lang.NullPointerException 

下面是完整的堆栈跟踪：

/opt/bitnami/apache-tomcat/conf/Catalina/localhost/solr.xml看起来像这样。

<?xml version="1.0" encoding="utf-8"?> <context crossContext="true" debug="0" docBase="/usr/share/solr/solr.war"> <environment name="solr/home" override="true" value="/usr/share/solr" type="java.lang.String"> </environment></context> 

在/ usr /共享/ Solr的的内容/也看起来很好

bitnami@ip-10-144-66-148:/usr/share/solr$ ls -l 
total 11384

-rw-r--r-- 1 tomcat tomcat 1676 Jul 17 2012 solr.xml 

不知道什么是错的，但是这是我的命:-(

问题是因为在该文件中/usr/share/tomcat7/conf/Catalina/localhost/solr.xml XML节点是小写字母，但它应该开始瓶盖 这是

<context crossContext="true" debug="0" docBase="/usr/share/solr/solr.war"> <environment name="solr/home" override="true" value="/usr/share/solr" type="java.lang.String"> </environment></context> 

应该

<Context crossContext="true" debug="0" docBase="/usr/share/solr/solr.war"> 
<Environment name="solr/home" override="true" value="/usr/share/solr" type="java.lang.String"> 
</Environment></Context>
