创建并运行容器

注意：-Xms -Xmx设置的值，两者需要一致

docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9101:9101 -p 9111:9111 -v /usr/local/elasticsearch/docker/config/es1.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /usr/local/elasticsearch/docker/data1:/usr/share/elasticsearch/data --name ES01 elasticsearch:5.6.9


docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9102:9102 -p 9112:9112 -v /usr/local/elasticsearch/docker/config/es2.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /usr/local/elasticsearch/docker/data2:/usr/share/elasticsearch/data --name ES02 elasticsearch:5.6.9


docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9103:9103 -p 9113:9113 -v /usr/local/elasticsearch/docker/config/es3.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /usr/local/elasticsearch/docker/data3:/usr/share/elasticsearch/data --name ES03 elasticsearch:5.6.9

boot连接测试

错误日志：
2020-08-06 15:17:05.587 ERROR 1257 --- [ main] .d.e.r.s.AbstractElasticsearchRepository : failed to load elasticsearch nodes : org.elasticsearch.index.mapper.MapperParsingException: analyzer [ik_max_word] not found for field [name]

解决：

docker cp /usr/local/elasticsearch/docker/ik 容器id:/usr/share/elasticsearch/plugins

安装ik分词器, 再重启ES容器就好了
