#==========================cdh solr4.10配置core =====================================================
#参考
http://blog.csdn.net/kissmelove01/article/details/45043955


1.生产实体配置文件
solrctl instancedir --generate nutch


2.创建 collection1 实例并将配置文件上传到 zookeeper
solrctl instancedir --create nutchtest nutch
#修改
solrctl instancedir --update nutchtest nutch


3.查看上传的实体
solrctl instancedir --list


4.上传到 zookeeper 之后，其他节点就可以从上面下载配置文件。接下来创建 collection
#其中-s表示设置Shard数为2，-r表示设置的replica数为2。
solrctl collection --create nutchtest -s 1 -r 1
#删除
solrctl collection --delete nutchtest
#增加share
solrctl --solr http://<target_solr_server>:8983/solr core --create <core_name> \
-p dataDir=hdfs://<nameservice>/<index_hdfs_path> -p collection.configName=<config_name> \
-p collection=<collection_name> -p numShards=<int> -p shard=<shard_id>  


5.启动服务并访问
bin/solr start
