搭建SolrCloud集群、上传solrhome的配置文件到ZooKeeper时报错：Could not find or load main class org.apache.solr.cloud.ZkCLI。
./zkcli.sh -zkhost 39.105.195.XX:2181,114.115.171.XX:2181,39.105.81.XX:2181 -cmd upconfig -confdir /usr/local/solr-cloud/solr-home/home8983/collection1/conf/ -confname myconf
./zkcli.sh: line 13: unzip: command not found
Error: Could not find or load main class org.apache.solr.cloud.ZkCLI错误提示是说：找不到命令、找不到org.apache.solr.cloud.ZkCLI这个类。
解决方案：
在你solr解压完成后的example目录下找到start.jar这个包，然后解压它。
我的是在/usr/local/solr-4.10.3/example这个目录、根据你自己解压的目录找到它。
#执行解压命令

上面的命令执行完成后、按Ctrl+c结束、或者打开一个新的xshell窗口。
然后在/usr/local/solr-4.10.3/example/scripts/cloud-scripts（按自己solr解压的目录）重新执行上传命令即可。
