修改配置修改elasticsearch目录下 config/elasticsearch.yml文件找到network和port字段，修改为你的ip和端口即可，重启es然后发现启动报错[1]: max file descriptors [65535] for elasticsearch process is too low[2]: max number of threads [3805] for user [es] is too low, increase to at least [4096][3

elastic下载地址https://www.elastic.co/cn/downloads/elasticsearch我下载的是7.10版本，但是这个版本启动需要jdk 11以上我最后选择linux下命令行下载，总之选择版本低点的wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.2.4.tar.gz 然后就是解压tar -zxvf elasticsearch-6.2.4.tar.gz启动.
