optional 1 - download pre-build package from here: https://github.com/medcl/elasticsearch-analysis-ik/releases
create plugin folder cd your-es-root/plugins/ && mkdir ik
unzip plugin to folder your-es-root/plugins/ik

optional 2 - use elasticsearch-plugin to install ( supported from version v5.5.1 ):
./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v6.3.0/elasticsearch-analysis-ik-6.3.0.zip
NOTE: replace 6.3.0 to your own elasticsearch version

2.restart elasticsearch

报错：
