$mkdir -p /usr/local/Cellar/elasticsearch/6.2.4/libexec/plugins/ik
$mv elasticsearch /usr/local/Cellar/elasticsearch/6.2.4/libexec/plugins/ik
重启es失败
原因 多了层目录
/usr/local/Cellar/elasticsearch/6.2.4/libexec/plugins/ik／elasticsearch 内部的东西移动到
/usr/local/Cellar/elasticsearch/6.2.4/libexec/plugins/ik
即可
重启

kibana 可以测试分词
GET _analyze?pretty
{
“analyzer”: “ik_smart”,
“text”:”安徽省长江流域”
}
分词结果
