为什么不能使用CentOS,plesk 9.2.1和tomcat 5.5进行solr 1.3.0安装？

好的,我只是通过其托管服务提供商为我的客户设置了专用服务器.他们在那里安装了plesk(版本9.2.1),此专用服务器的警告之一是,如果我在控制面板之外执行任何操作(即使用SSH)以执行任何任务,则它们不保证支持该软件组件.很好,因为无论如何我还是愿意使用控制面板来完成它,因为我要做的就是上传一个war文件来安装servlet.

但是,这是问题所在,在安装了最新版本的solr(1.3.0)之后,我在plesk中得到了一个警告图标,它给了我一个模糊的错误,例如“应用程序的实际状态与从数据库中检索到的状态不对应. ”

这是日志条目：

solr / home目录存在,那么为什么solr对此有所抱怨？

解决方法:

好的,这是问题所在！事实证明,有些tomcat发行版没有对xalan的引用,这是XPathFactory异常的来源.此错误可能会引起误解,因为它将错误记录为solr / home属性未设置的问题.事实是它已被设置. 10次​​中有9次由于未设置solr / home目录而导致启动solr出现问题.

这就是我自己修复它的方式：我进入/usr/share / tomcat5 / shared / lib目录,并创建到/usr/share / java目录中的xalan-j2.jar文件的符号链接.重新启动Tomcat并立即启动Solr！

其他一些技巧：
编辑您要上传的solr.war文件中的web.xml文件,然后将其取消封装,进行更改,然后将其重新封装.将目录设置为/usr/share / solr.这样,如果日志未显示其使用该目录作为solr / home,则存在问题.另外,确保solr / home看起来像这样：

/usr/share/solr/
/usr/share/solr/bin
/usr/share/solr/bin/rsyncd-stop
/usr/share/solr/bin/abo
/usr/share/solr/bin/scripts-util
/usr/share/solr/bin/snappuller-disable
/usr/share/solr/bin/backupcleaner
/usr/share/solr/bin/snapcleaner
/usr/share/solr/bin/rsyncd-disable
/usr/share/solr/bin/snapinstaller
/usr/share/solr/bin/commit
/usr/share/solr/bin/snappuller-enable
/usr/share/solr/bin/snappuller
/usr/share/solr/bin/backup
/usr/share/solr/bin/rsyncd-start
/usr/share/solr/bin/abc
/usr/share/solr/bin/rsyncd-enable
/usr/share/solr/bin/optimize
/usr/share/solr/bin/snapshooter
/usr/share/solr/bin/readercycle
/usr/share/solr/conf
/usr/share/solr/conf/schema.xml
/usr/share/solr/conf/solrconfig.xml
/usr/share/solr/conf/synonyms.txt
/usr/share/solr/conf/xslt
/usr/share/solr/conf/xslt/example_atom.xsl
/usr/share/solr/conf/xslt/luke.xsl
/usr/share/solr/conf/xslt/example_rss.xsl
/usr/share/solr/conf/xslt/example.xsl
/usr/share/solr/conf/elevate.xml
/usr/share/solr/conf/scripts.conf
/usr/share/solr/conf/protwords.txt
/usr/share/solr/conf/spellings.txt
/usr/share/solr/conf/admin-extra.html
/usr/share/solr/conf/stopwords.txt
/usr/share/solr/README.txt

具有user：group权限的用户必须是tomcat：tomcat.如果solr正常启动,将创建数据目录.

希望这可以为某人节省大量时间.
