各位：
我用的是TOMCAT+solr,直接启动没有什么问题，但使用命令方式：/usr/java/jdk1.6.0_31/bin/java -Dbootstrap_confdir=../webapps/solr/solrhome/conf -Dcollection.configName=clusterconf -DzkRun -DzkHost=localhost:3081,localhost:4081,localhost:5081 -DnumShards=2 -jar bootstrap.jar

直接启动，总会报个错
严重: Could not start Solr. Check solr/home property and the logs

请问下，这个问题大家是怎么解决的

兄弟，这个log里已经说的很清楚了吧，你用zookeeper cluster必须有个myid的文件，不然第一次选举没法儿完成。
